Americans have started to recognize interpersonal violence as a major health care issue.
Increasingly, clinicians are beginning to recognize both the high rate of victimization among
extremely poor women and its health consequences. However, most clinical responses focus
on the immediate effects of child abuse, partner abuse, and rape. The long-term medical and
mental health consequences and the relationship between early victimization and adult
problems are still largely ignored. This article focuses on medical and mental health needs of
extremely poor women survivors of interpersonal violence. It begins by documenting the
extent and nature of violence against low-income women. Special attention is focused on the
long-term sequelae of childhood abuse and on identifying and managing complex trauma
responses in these women. The article concludes by discussing obstacles to care and the
necessity of advocating for increased resources to respond to women living in extreme
poverty.
As the prevalence of homelessness among men increases, the impact of trauma and posttraumatic stress disorder in the lives of homeless men warrants attention. We will review
research and clinical reports on the impact of traumatic event exposure, the antecedents and
consequences of traumatic events, and homelessness among males in order to begin to
develop scientific, public health, and social policy answers to several questions. The nascent
clinical and scientific literature provides evidence of the need for prospective studies of the
etiology, epidemiology, course, and prevention of post-traumatic stress disorder among
males who are at risk for or in the early stages of homelessness. We attempt to summarize,
categorize, and suggest important variables and causal relationships that can inform future
research studies and interventions in order to contribute to the growth of this
underdeveloped and important knowledge base
Homelessness is recognised to be a traumatic event in itself and is often preceded by the
experience of violence. More recent research has indicated that homelessness can function to
enact growth and resilience in women with dependent children. This review paper draws
together findings from a series of studies involving women with dependent children who
experience homelessness. It identifies key psychosocial and health priorities in this
population and how findings related to resilience and growth can be harnessed in therapeutic

work. Pragmatic service developments and examples of good practice in therapeutic and
multi-agency interventions from the domestic violence and homelessness literature are
described and recommendations are made for developing services and working
therapeutically with marginalised and transient populations. Therapists need to work in a
flexible and integrated way with other key services, so that the crisis and long term needs of
this population are met
Homeless adolescents are some of this nation's most vulnerable and underserved youth and
comprise approximately one-quarter of all people who are homeless (Cauce et al., 2000).
Homelessness among youth populations has serious consequences for public health. Topics
discussed in this chapter include why youth become homeless; homeless youth victimization;
trauma and homeless youth; homeless youth case vignettes; intervention options and
recommendations; and social policy implications.

Respondents who reported physical abuse only, sexual

disorder, respondent psychiatric disorder, respondent
age, and income were also significant correlates of
running away.
We found that extremely poor women with lifetime
PTSD were more likely to have grown up in family
environments of violence, threat, and anger than
those without PTSD. The strongest risk factor for
PTSD was childhood sexual abuse with threat. Many
low-income women have difficulty using medical care
appropriately because of childhood histories of
physical and sexual abuse, the subsequent
development of post-trauma responses, and structural
barriers to care. Given these factors, it is critical that

health care clinicians routinely screen for histories of
violence and PTSD and develop treatment plans that
ensure safety, link current symptoms with prior
experiences, and provide support as necessary. A
team approach coordinated by a case manager may
be the best strategy. Without routine screening for
PTSD and sensitive treatment, many extremely poor
women will receive compromised health care and may
even be retraumatized.
In multivariate analyses, homeless and at risk
adolescents reported equivalent levels of family
conflict, early problem behaviour and low
opportunities and rewards for family involvement.
Compared to adolescents not at risk, at risk
adolescents were more likely to be female and to
show poorer social skills/assertiveness and depressive
symptoms. Compared to at risk adolescents, homeless
adolescents showed additional family, school, peer
and individual risks, but lower depressive
symptomatology.

nearly two-thirds reported severe physical violence by
a childhood caretaker, 42% reported childhood sexual
molestation, and 61% reported severe violence by a
male partner. Comparisons of homeless and housed
women are presented, and implications for prevention
and intervention are discussed in light of recent
welfare reform legislation
All women and over 90% of men reported at least one
event of trauma in their life. Fifty-eight per cent
suffered serious physical assault and 55% witnessed
someone being badly injured or killed. Half the women
and 10% of men reported that they had been raped.
CONCLUSION: The experience of at least one lifetime
event of trauma is almost universal among homeless
people in Sydney and is considerably higher than for
the USA general population. Reasons for such high
prevalence rates are discussed. Depression and
posttraumatic stress disorder are associated with a
history of trauma. Health professionals need to be
aware of past events of trauma among individuals
who are homeless.
Results of analyses suggest that homeless youth come
from generally troubled backgrounds and have
elevated rates of psychiatric disorders. For boys, their
histories typically include physical abuse during
childhood, physical assault on the street, and elevated
rates of externalizing disorders. For girls, histories are
more often marked by sexual abuse during childhood,
sexual victimization on the streets, and elevated rates
of internalizing disorders. Implications of these results
for service delivery are discussed.

hypotheses that characterize the young homeless
population as experiencing higher rates of childhood
adversity and psychiatric disorder than their domiciled
contemporaries. A tentative model is suggested
whereby childhood experiences, educational
attainment and the prior presence of psychiatric
disorder all independently increase the likelihood of
homelessness in a youthful population
The prevalence of childhood abuse in this sample of
women was substantially higher than among homeless
women in general. The experience of childhood abuse
was related to increased suicidality, and resulted in
symptoms of posttraumatic stress disorder for some
women. Women who had suffered abuse were also
much more likely to become homeless during
childhood and it is suggested that this is an important
precursor to homelessness for many homeless women
with chronic and severe mental illness.
Homelessness is a risk factor for psychological trauma,
including implications of trauma theory improving
psychosocial conditions of homelessness.
The only between-group difference was that a
significantly higher proportion of housed mothers had
experienced sexual abuse in adulthood. However, both
groups had high lifetime prevalence rates for all forms
of abuse. Data suggest that mental health services are
urgently needed for both populations because of the
traumatic psychological effects produced by
homelessness and abuse.
Rates of childhood maltreatment were substantial.
Further, almost all youth experienced at least one
traumatic event, with most experiencing multiple types
of trauma. Gender differences were found in the
types, but not prevalence or magnitude, of childhood

Partial symptomatology of PTSD was common for
females but not males. Symptoms of depression and
anxiety were found to co-occur with PTSD for females,
which may complicate treatment efforts.
Most of the respondents came from backgrounds
characterized by severe emotional deprivation and
physical or sexual abuse. Of the 140 who completed
the full interview, 90 percent fulfilled DSM-III-R
criteria for an emotional or behavioral disorder. Fiftynine percent had conduct disorder, three-quarters
were depressed, 41 percent had considered suicide,
and more than one-quarter had attempted suicide
Significant differences in families of origin among
these three groups were identified. On univariate
analysis, homeless persons were found to have an
increased prevalence of alcoholism in the family of
origin, earlier departure from the home, minority
status, a self-described negative childhood,
experiences of abuse as a child, high birth order in
large families, less parental education, less-skilled
parental occupations, less feeling of love in the
childhood family, less likelihood of the father being in
the home, more risk of the father having been in jail,
and less identification with a religious group.
Multivariate analysis revealed that compared to the
study groups, the following family of origin factors
were associated with homelessness: ethnic group,
alcoholism, feeling loved as a child, and having one's
father in jail.
Lack of care from a parent during childhood sharply
increased the likelihood of subsequent homelessness
(odds ratio [OR] = 13), as did physical abuse (OR =
16). Sexual abuse during childhood was associated

with a nonsignificant trend toward homelessness (OR
= 1.7). The risk of subsequent homelessness among
individuals who experienced both lack of care and
either type of abuse was dramatically increased
compared with subjects reporting neither of these
adversities (OR = 26). CONCLUSIONS: Adverse
childhood experiences are powerful risk factors for
adult homelessness. Effectively reducing child abuse
and neglect may ultimately help prevent critical social
problems including homelessness.

Why became
homeless
In professional discourses, homeless young people are
often portrayed as victims of physical abuse and
emotional neglect. Although participants' narratives
reveal that abuse and neglect play a central role in
their decisions to leave home, many maintain a sense
of agency in the recounting of how they became
homeless.
The sample presents with extensive psychopathology
and a history of physical and sexual abuse. Gender
differences indicate that, except for antisocial
personality, females yield higher rates on measures of
both psychiatric disturbance and abuse. The
relationship between psychopathology and abuse also
appears to be much stronger for females than for
males. However, the relationship between abuse and
adult homelessness appears to be similar for men and
women. The gender differences in the relationship
between histories of abuse and manifestations of
psychiatric disturbance support a hypothesis that has
been proposed elsewhere: Females internalize the
trauma associated with abusive experience, while
males externalize it. The findings suggest that,
although there may be a need for gender-specific

targeted interventions, treatment providers must also
recognize that the impact of abuse seems to
transcend gender within this population.
In this sample, 86% of the population (74% of the
males and 90% of the females) reported at least one
physically abusive experience. The data reported
suggest that this population of adolescents have been
the victims of chronic, extreme abuse, experienced at
a young age, often perpetrated by the biological
parent (most often the mother), and was initiated
prior to the first runaway episode. Female runaways
were at greater risk than males for all types of abuse
experience. Once youths left home, the physical abuse
experiences decreased in frequency, but grew in
severity, particularly for males
Results indicate that: (1) being abused or neglected in
childhood increases the likelihood of running away
from home; (2) both childhood victimization and
running away increase the risk of juvenile arrest; and
(3) chronic runaway youths are at greater risk of
arrest. Running away increases the risk of juvenile
arrest for both childhood victims and nonvictims, and
therefore does not mediate the relationship between
childhood victimization and delinquency. The effect of
running away is stronger for non-abused and nonneglected youths. This unexpected finding suggests
that all runaways are at risk for delinquency regardless
of childhood victimization
20.7% of children were found to have high
hopelessness and 8% of children had depression. 2%
of children revealed that they had attempted suicide
at any point of time in life. Among children with high
hopelessness, 3.2% had ever attempted suicide. 8.3%

abuse, 14.6% of sexual abuse and a large number
reported substance abuse. 69.33% were found to
have behavioral problems (i.e. scored above the
recommended cut off score of 9). 81% of children had
antisocial behavior, 7.8% were neurotic and 10.5%
remained undifferentiated.
Analyses revealed that the number of stressful life
events and the presence of a co-occurring mental
health disorder were both significant predictors of the
severity of trauma symptoms. Findings suggest that
treatment professionals working with this population
should assess for stressful life events and trauma
symptoms as part of a comprehensive approach to
substance abuse treatment for homeless men.
Discuss 5 trajectories into homelessness. More

The detrimental effects of traumatic experiences often
inhibit homeless youths' ability to employ the
psychosocial skills necessary to a transition out of
homelessness. Consequently, interventions targeting
the mitigation of post-traumatic stress symptoms
among this population are crucial. This article aims to
address the symptoms and needs of unaccompanied
homeless youth who experience post-traumatic stress
disorder symptomatology and offers a strength-based
intervention framework for understanding, identifying,
and beginning to address trauma-related mental
health needs within the cultural context and
experience of youth homelessness

factors (poverty, lack of employment, low welfare
wages, lack of affordable housing) and personal
vulnerability (childhood abuse or neglect, mental
health symptoms, impoverished support networks,
substance abuse). Chronically homeless individuals
often reported experiences of severe childhood trauma
and tended to attribute their continued homelessness
to a substance abuse problem. It is concluded that
both macro anal individual level factors must be
considered in planning programs and services to
address the issue of homelessness in Canada.
Relationships were demonstrated between use of
defenses and specific as well as cumulative
victimization experiences. All levels of defenses
became more pervasive in response to victimization,
but this was not a predictor of overall immature
defensive functioning. CONCLUSIONS: Clinical and
program interventions to engage homeless youth need
to incorporate an understanding of the relationship
between defenses and victimization in order to be
effective in maximizing upon the strengths of this
population.
Most subjects with PTSD had an additional lifetime
psychiatric diagnosis. No consistent pattern of
association was apparent, however, between
individual diagnoses and either traumatic events or
PTSD. In almost three-fourths of both men and
women, the onset of PTSD had preceded the onset of
homelessness. Childhood histories of abuse and family
fighting were predictive of both traumatic events and
PTSD. The results suggest that factors leading to
PTSD in the study sample began long before the onset
of homelessness and may overlap with factors
operative in the genesis of homelessness.

Many subjects had experienced a traumatic event, and
post-traumatic stress disorder was very common.
Substance abuse and other Axis I disorders were
associated with a history of a traumatic event. The
majority of men and a substantial proportion of
women also had a history of physically aggressive
behaviors, often beginning in childhood. Aggressive
adult behavior was associated with substance abuse
and major depression. The aggressive behaviors
usually predated homelessness, and about half
continued after the individual had become homeless.
Thirty-nine percent of the women reported being
physically and/or sexually assaulted as adults.
Controlling for potential confounders, victimized
women were more likely than others to have a history
of childhood sexual and physical abuse, lifetime
substance use, greater mental health
symptomatology, and current risky sexual activity.
Thus, homeless women with mental health and
substance abuse problems ought to be screened for
violent experiences and encouraged to obtain
treatment appropriate to their problems to reduce
their ongoing risk of victimization.
Results indicate that clear behavioral indicators of
maltreatment can be observed among runaway and
homeless youth, which varied as a function of gender,
type of maltreatment, and the reason the youth
sought services from the program. One of the most
common behavioral indicators of maltreatment
observed had to do with school failure. Data showed
several gender differences including the fact that girls
tended to engage in victim type behaviors while boys
tended to be more anti-social. All of the behavioral

indicators pointed to a high degree of psychological

Results highlight the diversity of trauma. In a
longitudinal analysis, women who lived in shelters or
experienced major violence had a twofold increase in
their risk of depression over the 6-month follow-up. In
a cross-sectional analysis, childhood sexual abuse,
living in a shelter, physical violence, childhood physical
abuse, and death or injury of a friend or relative
predicted avoidant coping and symptoms of
depression. Active coping and depression predicted
mental health service seeking among traumatized
women. Modifying coping strategies may ameliorate
some of the negative impact of trauma and potentially
enhance mental health service use among at-risk
women.
Sixty percent of the sample reported sexual abuse,
which was significantly related to loneliness and
inversely related to connectedness and perceived wellbeing. Subjects felt lonely and disconnected. They
perceived their well-being in terms of current health
status.
Over 60% of the sample reported a history of sexual
abuse; the majority were under the age of 12 years
when they first tried alcohol, marijuana, and cocaine;
56.3% had injected drugs, and 46.9% had tried
inhalants. A disproportionate number of Hispanics
(95% of the sample) reported a history of sexual
abuse. Participants with a history of sexual abuse
were significantly more likely than those who did not
have a history of sexual abuse to have used alcohol
and/or marijuana (chi square = 9.93, p < .01) and to

Postmilitary social isolation, psychiatric disorder, and
substance abuse had the strongest direct effects on
HML, although substantial indirect effects from
stressors related to being in the war zone and from
premilitary conduct disorder were observed. Several
premilitary factors (e.g., year of birth, childhood
physical or sexual abuse, placement in foster care
during childhood) also had direct effects on HML.

While it has been established that attachment is a
salient factor with regard to childhood maltreatment
and later psychosocial problems, there is a dearth of
information on how homeless youths' thoughts and
feelings about attachment may also be linked to
behavioral risks including alcohol and substance use.
This exploratory study examines older homeless

illuminate the relationship between these factors and

Prevalence
The majority of the sample had experienced at least
one traumatic event in their lifetime (98%). Indeed,
the mean number of traumas per person was six. The
12 month prevalence of post-traumatic stress disorder
was higher among homeless adults in Sydney in
comparison to the Australian general population (41%
vs 1.5%). But 79% of the sample had a lifetime
prevalence of post-traumatic stress. In 59% of cases,
the onset of post-traumatic stress
disorder preceded the age of the first reported
homeless episode. CONCLUSIONS: Homeless adults in
Sydney frequently experience trauma and posttraumatic stress disorder. The study found that
trauma and post traumatic stress disorder more often
precede homelessness, but re victimization is
common. These findings highlight the high mental
health needs among homeless people and have
implications for services for homeless people.
Prevalence
Ninety-eight percent of participants had elevated
PTSD symptom scores. Although use of inhalants and
LSD was associated with PTSD symptoms, only
depression, anxiety, and dissociation, mother's ecstasy
or LSD use, youth's worry about family relationships,
and poor family communication predicted higher PTSD
scores. Runaway/homeless youth entering emergency
shelters services must be evaluated concerning
trauma and associated comorbid symptoms
Findings indicate that adolescents exposed to neglect

abusive homes longer (beta=.15) than their similarly
situated urban counterparts.
The most common reason for running away was;
beating by parents/relatives, followed by a desire for
economic independence (28.5%). Other reasons were
maltreatment by step parent/s, being both parents
dead argument with parent etc. The factors emerging
can be useful for identifying high-risk families with
children in pre adolescent age and hence for
prevention and rehabilitation
Multiple forms of child maltreatment, family
alcoholism, drug use, and criminal activity
characterized early family histories of many youth.
Leaving home because of either running away or
being removed by child protective services often
resulted in multiple transitions, which regularly
included moving from foster care homes to a group
home, back to their parents, and then again returning
to the streets
Approximately one-half of these young people
reported being physically abused and almost one-third
experienced sexual abuse. Females experienced
significantly higher rates of sexual abuse compared to
males, and sexual minority youth experienced
significantly higher rates of physical and sexual abuse
compared to heterosexual youth. Average duration of
physical and sexual abuse was 5 and 2 years,
respectively. Both types of abuse were rated as
extremely violent by more than half of those who
were abused. The average number of different
perpetrators of physical and sexual abuse was four
and three, respectively. Biological parents were the
majority of perpetrators for physical abuse whereas
non-family members most often perpetrated sexual
17
abuse. Average age of perpetrators was late 20s to
early 30s and the majority of perpetrators were male
for both types of abuse. CONCLUSIONS: The pattern
of exploitation and victimization within the family may
have serious and cumulative developmental
consequences for these youth as they enter the street
environment. Early intervention programs are needed
to break the cycle of exploitation and abuse that
adolescents experience within the family. Without
intervention, many of these youth may be at risk of
future exploitation and re-victimization out on the
street.

The authors provide data in this descriptive study to
suggest that physical and sexual abuse within the
family system frequently expedites youths' decisions
to leave home. The role that drugs and alcohol play in
runaway youths' lifestyles is also explained
Homeless families taking part in the 2003 study were
poorer than those taking part in the 1993 study, and
female heads of household in that study reported
more physical health limitations, major depressive
illness, and posttraumatic stress disorder.
Both the parents/caretakers and their runaway
adolescents reported lower levels of parental
monitoring and warmth and supportiveness and higher
levels of parental rejection than comparison groups of
nonrunaway families. Parents/caretakers and runaway
adolescents reported high levels of family violence and
sexual abuse. Similarly, they concur regarding conduct
problems for the adolescents. The findings suggest
that runaway and homeless adolescents accurately
depict the troubled family situations that they choose
18

to leave. The policy implications for recent debates
involving criminalization and mandatory return to
parental custody of homeless and runaway youth are
discussed.

Outcome
Homeless and housed mothers had similar rates of
psychiatric and substance use disorders. Both
groups had higher lifetime and current rates of
major depression and substance abuse than did all
women in the National Comorbidity Survey. Both
groups also had high rates of posttraumatic stress
disorder and two or more lifetime conditions
In people with psychosis, there is a marked excess
of victimising experiences, many of which will have
occurred during childhood. This is suggestive of a
social contribution to aetiology.

analyzed using phenomenological analysis

perceived childhood physical, sexual, and
psychological abuse and neglect to be among the
biopsychosocial antecedents to their becoming
chemically dependent.
Three aspects of physical and sexual assault were
assessed: lifetime prevalence; severity, cooccurrence, and recency; and associations between
levels of this victimization and specific
characteristics of the women. Results indicate that
the life-time risk for violent victimization was so high
(97%) as to amount to normative experiences for
this population
Sexually abused participants had significantly less
future time perspective (p = .05), fewer sexual selfcare behaviors (p = .04), and less social support
than non-abused participants (p = .01) and almost
significantly more sexual risk-taking (p = .08).
However, no significant differences were found
between abused and non-abused participants on
sexual self-concept, self-efficacy or intention to use
condoms, safe sex behaviors, AIDS knowledge,
assertive communication, or self-efficacy to perform
testicular/ breast self-exams. Overall, participants
who did not report a history of sexual abuse had
significantly more sexual health resources and
engaged in fewer sex-risk behaviors than those who
reported having been abused. These differences
have notable implications for screening adolescents
for a history of sexual abuse. Adolescents who

We found that male and female abuse victims differ
in terms of their cognitive-perceptual and behavioral
factors associated with sexual health practices. Early
identification of those who have been abused is
critical so that interventions can be developed.
Effective short-term interventions are needed for
the adolescent victims of Child Sexual Abuse (CSA),
particularly those who are homeless and prone to
further sexual victimization.
Analyses revealed that the number of stressful life
events and the presence of a co-occurring mental

the severity of trauma symptoms. Findings suggest
that treatment professionals working with this

family dysfunction and had to cope with low selfesteem, emotional distress, and poor physical
health. The initiation of drug and/or alcohol use was
strongly affected by the social influence of other
users. In comparison, homeless women who did not
use drugs or alcohol reported a positive self-image,
few traumatic events, and chose partners who did
not use drugs or alcohol. Common among current
drug and/or alcohol users were the reported social
benefits of drug use. Quantitative analyses revealed
homeless women who were current drug users were
significantly more likely to have experienced
childhood and adult victimization as compared with
women in the other groups
Physical abuse and parental drug abuse predicted
daily drug use in the whole sample and selected
subgroups, whereas parental alcohol abuse
predicted daily alcohol use in the whole sample.
Teen self-esteem was also found to have a
protective effect on daily alcohol use for the sample
and for African American women. Negative peer
influence in adolescence predicted daily drug use
among high-acculturated Latinas. In summary,
childhood abuse, parental substance use, and
negative peer influence affect important roles in
homeless women’s daily substance use.
Therefore, the members of Group B have a higher
probability of being diagnosed as having a conduct
disorder, being male, and associating with
delinquent peers. This group had not experienced a
higher level of parental violence. The opposite is
true for the members of Group A. Conclusion: Our
study demonstrates that parental violence and
behavioral problems are variables that are

independently related to the defined categories of

constitute, as some thinkers have claimed, the
components of a unique dynamic able to explain the
phenomenon of the runaway. Our results vitiate the
doubts sometimes expressed by researchers about
the importance of parental violence to the
phenomenon of adolescent runaways.
In line with predictions, more current substance use
was related to less PTG, more reliance on avoidant
coping once approach coping was accounted for,
and greater PTSD symptomatology. Levels of
growth were comparable to those found in samples
with less trauma exposure.
Adverse childhood events were precursors to
adulthood alcohol and drug use. Consistent
substance use was negatively associated with longterm labor force participation and with social service
utilization among homeless adults. Adverse events
at childhood, however, were positively associated
with service use. Conclusions: Adverse childhood
events may contribute to negative adulthood
consequences, including consistent substance use
and reduced labor force participation. Agencies that
are involved in halting the abuse or neglect also
should participate in more preventive interventions.
Job-related assistance is particularly important to
facilitate employment and labor force participation
among homeless adults.

early sexual abuse in the home had a positive direct
effect on sexual victimization of adolescents on the
streets. Early sexual abuse also increased the
likelihood of later sexual victimization indirectly by
increasing the amount of time at risk, deviant peer

women who leave dysfunctional and disorganized
homes often characterized by abuse continue on
negative developmental trajectories once they reach
the streets. The social context of street life puts
these adolescents in close proximity to potential
offenders and exposes them to crime and criminals.
The combination of a negative developmental
trajectory and the high-risk street environment
increases these young women's chances of being
sexually victimized
Data on levels of physical and sexual abuse within
family of origin, participation in deviant subsistence

A review of the relevant literature is followed by an exploration of the complex relationship, especially for
women, between homelessness and mental health. Various mental health and gender-related concerns that
have implications for the design of interventions for homeless women are explored

The state of Anglo-American research on psychiatric disorders among homeless persons is summarised. Several
authors reported on life-time prevalence (50-75%) and present prevalence rates (30-50%) of psychiatric
disorders in this population. Alcohol-related and drug-related disorders were most frequent. Most studies,
however, only included single and male subjects, while there is little information on homeless persons living
with a partner or in a family. Up to now, no representative studies exist. Some recent investigations evaluated
classic single case models versus case management approaches. Short-term programmes only yielded shortterm effects, but linking psychiatric and social services seems to improve health service utilization by the

disorders were alcohol dependence, which ranged from 8.1% to 58.5%, and drug dependence, which ranged
from 4.5% to 54.2%. For psychotic illness, the prevalence ranged from 2.8% to 42.3%, with similar findings
for major depression. CONCLUSIONS: Homeless people in Western countries are substantially more likely to
have alcohol and drug dependence than the age-matched general population in those countries, and the
prevalences of psychotic illnesses and personality disorders are higher. Models of psychiatric and social care
that can best meet these mental health needs requires further investigation
This article systematically reviews studies of prevalence of schizophrenia in homeless persons.
Describes recent research on the prevalence of alcohol, drug, and mental (ADM) disorders and the
characteristics of homeless substance abusers and persons with mental illnesses. Methodological problems in
homelessness research are reviewed, particularly in relation to definitions of homelessness and sampling- and
case-ascertainment methods. Prevalence rates of ADM disorders are much higher in homeless groups than in
the general population.
Reviewed literature on psychological distress and psychiatric disorders among homeless youth in Australia, and
compared these rates with Australian youth as a whole. 14 separate studies were located. Homeless youth in
Australia have extremely high rates of psychological distress and psychiatric disorders. As homeless youth are
at risk of developing psychiatric disorders and possibly self-injurious behavior the longer they are homeless,
early intervention in relevant health facilities is required
We have set out to assemble a practical clinical guide for work with homeless people who have mental illness,
written by clinicians, for clinicians. It approaches treatment and rehabilitation from the vantage point of the
treatment environment, from street to housing--and, we hope, almost everything in between. The ideas in this
book reflect what we believe is the evolution of consensus on a clinical approach to the homeless mentally ill
person, developed over more than two decades by many experts but until now not assembled in a detailed,
practical format.
The rapidly growing, but still small, research literature on homelessness in Europe has often been provided by
non-academics, using qualitative methods, and has been published in sources that are not widely available.
This article summarizes definitions employed, observed prevalence, the socio-demographic characteristics, and
the physical and mental health status of the homeless in Western Europe. Research pertaining to the causes of
homelessness and the societal response to the problem are also reviewed, and the ethical and methodological
questions raised by European researchers are debated. A critical analysis of the largely descriptive European
research is provided, and some noteworthy exceptions are described. We also discuss a number of promising
theoretical models, including those that focus on learned helplessness, social strain, and social stress
Significant mental illness is present in 30-50% of the homeless: functional psychoses predominate; acute
distress and personality dysfunction are also prevalent. Co-morbidity of mental illness and substance abuse
occurs in 20%, and physical morbidity rates exceed those of domiciled populations. The homeless mentally ill
26
also have many social needs. Pathways to homelessness are complex; deinstitutionalization may be only one
possible cause of the increase in the number of homeless people. This review outlines the research, highlights
current views on the definition and classification of homeless populations, and offers some guidelines on
avenues which need to be explored
This paper reviews 18 surveys of mental health problems among homeless adolescents and reports on a pilot
study of the same topic conducted in Amsterdam. Sampling methods and measures of mental health are
discussed. The reported estimates of mental health problems vary greatly, very probably because of
methodological differences. Despite the different methods used, there seems to be considerable research
evidence to support a high prevalence of mental disorders among homeless adolescents. The results of the
pilot study of 50 homeless adolescents in Amsterdam are consistent with the surveys reviewed. A highly
structured interview was conducted at all four services sites for homeless adolescents in Amsterdam. Of the
homeless adolescents interviewed, 78% had at least one lifetime DIS/DSM-III-R diagnosis, and 64% had at
least one 1-month diagnosis
Research on the mental health and service needs of homeless seniors has been scant. This paper reviews the
available literature and presents findings of a Toronto survey in an effort to describe the demographics of
homeless seniors, their level of impairment, and their mental and physical health needs. Although seniors
represent a small percentage of the homeless population, their numbers are growing. The available literature
suggests a high prevalence of psychiatric disorders and cognitive impairment in this population, with a greater
proportion of older women than men having severe mental illness.

Outcome
The results show that 58% of the homeless
adolescents were exposed to continuous violence in
their families and that violence was a major reason
for them to leave home. The overall prevalence of
diagnosed psychiatric disorders was 80% in the
whole sample; the leading disorder was substance
abuse/dependence (65%), followed by mood
disorders (42.5%), anxiety disorders (17.5%) and
eating disorders (17.5%). Duration of homelessness
had the greatest influence on the prevalence of
mental disorders. Longer duration of homelessness
was associated with a higher risk of psychiatric
disorder or self-harm. These results demonstrate the
urgent need for early psychosocial and psychiatric
help for homeless adolescents
In 44/98 (44.9%), a formal DSM-IV axis I psychiatric
disorder was diagnosed, most common being
dementia (15/44) and schizophrenia (15/44). A
significant minority of 13/44 (29.5%) were
diagnosed and treated prior to becoming homeless.
Physical co-morbidity was found in nearly 2/3
subjects. Following intensive case-management by
social workers, 35/44 (79.5%) subjects were
successfully placed in permanent housing.
The vast majority were found to have severe
psychological illnesses that largely remained
untreated. Approximately 91% were given primary
psychiatric diagnoses: About 40% had psychoses,
29% were chronic alcoholics, and 21% had
personality disorders. Approximately one-third had
been hospitalized for psychiatric care. The authors

one. Childhood sexual abuse was associated with
conduct disorder, while living in a home where drugs
were used was associated with aggression. Severe
aggressive behavior was associated with other
problem behaviors, including attempted suicide,
behavior that precipitated residential psychiatric

compared with those who exhibit adolescent-onset
conduct disorder, youth with childhood onset are
more likely to engage in a series of antisocial
behaviors such as use of sexual and nonsexual
survival strategies. Second, youth with childhoodonset conduct disorder are more likely to experience
violent victimization; this association, however, is
mostly through an intervening process such as
engagement in deviant survival strategies.
The homeless sample were younger and more likely
to be male than their domiciled counterparts. They
had more often spent time in institutional child care
and had worse educational records and lower levels
of employment. Young people who were homeless
had greater involvement with the police, more
frequently used illicit drugs and reported worse
physical and mental health than those in private
households. They were equally likely to see a general
practitioner and more often consulted for 'nerves' as
well as having a higher rate of contact with mental
health professionals
Homeless patients were more symptomatic and
behaviorally disturbed than controls. They were
significantly more likely to have a criminal history
and to be identified by key workers as having
problems related to substance use. Homeless
patients were less likely to have been born in
Birmingham and to have ongoing contact with
childhood carers but despite being less aware of the
need for treatment, uptake of psychiatric care was
comparable with that of controls. The implications

Very high rates of all personality disorders were

borderline, 20% histrionic, 57% narcissistic) and C
(50% avoidant, 25% dependent, 57% obsessive

sample. At least one Cluster A disorder was
diagnosed in 92% of the sample, and these disorders
were distinguished from Axis I psychotic disorders
(20%) with regard to prevalence, patterns of
association, and constellation of symptoms. Cluster A
disorders were not associated with any Axis I
disorder, suggesting diagnostic independence in this
sample.
Nearly one out of three homeless subjects (32.7%)
presented with a psychotic disorder, a higher
proportion than that found in non-homeless subjects
(15.7%). Compared to non-homeless subjects with
psychosis, homeless subjects with psychosis were
more likely to be male and to present with drug use
disorder.
There was a high prevalence of mental illness among
the Ss and this was a factor in the entry to
homelessness in many cases. There were indications
that some Ss with mental health problems became
homeless because their needs had been neglected or
undetected. Mental health problems also had an
impact on the circumstances of older homeless
people and affected their ability to seek and accept
help.

younger individuals have different vulnerabilities to
homelessness.
the following lifetime prevalence rates were
obtained: 91.8% for substance use disorder (82.9%
alcohol dependence), 41.8% for affective disorders,
22.6% for anxiety disorders and 12.4% for
schizophrenia. Of the homeless males in Munich,
94.5% had at least one DIS/DSM-III axis I diagnosis.
Six-month prevalence data is also presented. Results
are compared with those of a very similar study on
homeless individuals in Los Angeles, which also used
DIS/DSM-III diagnoses. In comparison with
representative community samples in the United
States and in Germany, mental illness was much
more frequent among homeless individuals in Munich
as well as in Los Angeles. Implications for health
care planning are discussed.
Rates of mental illness decreased from 79 % to 66%
over 3 years possibly due to an improved housing
situation and increased medical/psychiatric attention
and service. The prevalence of mood disorders,
substance use disorders and anxiety disorders was
significantly lower at 3-year follow-up while psychotic
disorders showed a slight increase over time. A high
rate of use of general medical inpatient services was
found. Considering the very high prevalence of
mental illness, the use of psychiatric services was
very low with some increase over time.

Results point to very high prevalence rates of mental

frequent diagnostic groups were alcohol and drug
abuse (lifetime prevalence rate 90.6%), affective
disorders (50.0%), anxiety disorders (43.8%) and
schizophrenia (21.9%).
Twenty-one percent of the cohort was classified as
having mental illness. Seventy-two percent had a
diagnosis of drug abuse or dependence, and 51
percent had alcohol abuse or dependence. Persons
with mental illness also experienced homelessness of
some kind over a significantly longer period
Analyses indicated that Ss' lifetime and current rates
of major mental illnesses were disproportionately
high when compared with a household sample for
the city. 12% of the Ss had dual diagnoses of
chronic major mental illness and chronic substance

Rates of schizophrenia, bipolar disorder, and
somatization disorder were not significantly different
between homeless and non-homeless groups. Major
depression was about four times as prevalent in nonhomeless men as in homeless men. Homeless men
were significantly more likely than non-homeless
men to qualify for a diagnosis of alcohol use
disorder, and homeless women were more likely
than other women to qualify for a diagnosis of drug
use disorder. Both homeless men and women were
significantly more likely than their domiciled
counterparts to meet criteria for antisocial
personality disorder. Personality disorder other than
antisocial was more prevalent in nonhomeless men
than in homeless men. Combined rates of personality
disorder were significantly higher among homeless
than non-homeless women, but not men.
In this sample of homeless men and women, most,
but not all, adult symptoms of antisocial personality

support the appropriateness of the diagnosis of

populations. It cannot be said from these data that
homelessness often leads to antisocial behaviors
They report negative and stigmatising descriptions of
mental health despite their involvement with a
mental health service. Four key interpretative
repertoires are identified; denial of problems, mental
health as negative, the need to talk, and challenging
prejudice. It is concluded that the term 'mental
health', which appears in the title of the service (of
which they are clients), presents barriers for usage
but works to challenge prejudice and educate young
people.
Use of eight types of services over a 26-month
period was examined. Individuals whose primary
presenting problem was subsistence needs were
more likely to be housed than those whose primary
problem was mental, illness or substance abuse.
Those with a diagnosis of personality disorder used
fewer services. Housed individuals were more likely
to use services than those who were homeless
32% had a more narrowly defined form of
depression, 15% a schizophrenic disorder (DSM-IIIR-codes 295.00-295.70) and 52% an antisocial

schizophrenia it concerned a 6-month prevalence

The majority of the youth in our sample met criteria
for dual or multiple diagnosis (60%) with many
having more than one substance-use diagnosis
(56%). The severity of mental-health and
substance-use problems in this sample of substanceabusing runaways suggests the need for continued
development of comprehensive services. The range
and intensity of diagnoses seen indicates a need for
greater focus on treatment development and
strategies to address their multiple areas of risk.
Schizophrenia and bipolar affective disorder account
for only a small portion of the mental illness in these
women. Nearly one in three has a history of
substance abuse, with drug abuse being more
prevalent than alcoholism. One third of the sample
met lifetime criteria for posttraumatic stress disorder.
One fourth of the women have received inpatient
psychiatric care, and the majority with a
nonsubstance Axis I diagnosis have received some
mental health treatment.

mental health needs could be met by services
operating on the interface with specialist services, if
these are jointly planned and co-coordinated.
Thirty-one per cent fulfilled the diagnostic and
statistical manual (DSM: 111R) criteria for a
diagnosis of schizophrenia and more than half were
not in contact with psychiatric services. This
suggests that a significant number of male
schizophrenics are lost to follow-up and become
homeless.
Lower use of problem-focussed coping was
associated with poorer mental health at the time of
homelessness. Mental health problems improved
over time, but levels of psychopathology remained
high at follow-up. Most women had achieved their
primary goal of resettlement, and this was associated
with use of problem-focussed coping. Lower use of
problem-focussed coping, in particular, acquiring
social support, was associated with continuation of
mental health problems at follow-up, however the
greatest predictor of mental health at follow-up was
mental health status whilst homeless. Despite
exposure to major stressors and poor mental health,
mothers experiencing homelessness can maintain
their ability to cope effectively, in order to achieve
their goals.

scores on pathological dimensions of personality
(borderline features, antisocial traits, and
aggressivity) and differed primarily on the dimension

personality dysfunction and the fourth did not
deviate from adult nonclinical norms. Brief
personality assessment can be a cost-effective
approach to matching services with clinical needs of
homeless adults by attending to interpersonal
dimensions that will likely affect service provision
The prevalence of diagnosed psychiatric disorders
was 71 %; the leading disorder was substance
abuse/dependence (43 %), followed by anxiety
disorders (35 %) and schizophrenia (12 %). Multiple
diagnoses were made in 35 % of the women.
DISCUSSION: Striking features were the often early
onset of homelessness and the reticence in seeking
help. The flight from violence was a crucial
precipitant of the loss of the home and should also
be discussed in the context of the development of
the psychiatric disorders.
About one-third (35.5%) of the runaways met
lifetime criteria for PTSD and 16.1% met 12-month
criteria for the disorder. More than 90% of the
adolescents who met criteria for PTSD met criteria
for at least one of the other four diagnoses.
Multivariate analyses indicated that correlates of
PTSD were age of adolescent, being female, having
experienced serious physical abuse and/or sexual
abuse from an adult caretaker, and having been
assaulted or injured by weapon when on the street.

A literature review of homeless service users' perceptions of services for homeless mentally ill people was
supplemented by a qualitative in-depth survey of 10 homeless people. This article reports on their views about the
services they receive. Mismatch between expectations and provision, disputes with healthcare providers, dissatisfaction
with the degree to which they have choice in their care, and suspicions about the intentions of health professionals
demonstrate the extent to which powerlessness and social exclusion are replicated in healthcare economies.
Despite recent prosperity in the U.S., homelessness is still a widespread social problem. It is estimated that 25% of
homeless persons have a serious mental illness. This article will review the literature evaluating prevention services and
specialized outreach, treatment, and housing programs designed to reduce homelessness for individuals who are
mentally ill. Although these interventions have been helpful in addressing the complex needs of the homeless mentally
ill, it is difficult to measure how they have improved outcomes. It is even more challenging to determine whether the
programs are cost-effective.

no significant differences on any measures of
psychiatric or substance abuse status or
community adjustment, although HUD-VASH
clients had larger social networks. From the
societal perspective, HUD-VASH was 6200 US
dollars (15%) more costly than standard care.
Incremental cost-effectiveness ratios suggest
that HUD-VASH cost 45 US dollars more than
standard care for each additional day housed
(95% confidence interval, -19 US dollars to
108 US dollars). CONCLUSIONS: Supported
housing for homeless people with mental
illness results in superior housing outcomes
than intensive case management alone or
standard care and modestly increases societal
costs.
Stepwise regression results indicated that a
history of sexual abuse and suicide attempts
were the two strongest predictors of the
treatment attendance rate, higher attendance
among those with these histories. Youths who
attended greater than 6 treatment sessions
showed a significant reduction in alcohol use
at post-treatment, but attendance rates did
not impact other substance use.
Youth assigned to EBFT reported greater

compared to youth assigned to SAU while
other problem areas improved in both
conditions. Findings suggest that EBFT is an

Among the referred clients, the prevalence of

48.5%, respectively. At 6 months, 24 clients
(35.3%) had improved clinically, and 33

identified 2 factors associated with clinical
improvement: the number of visits with a
psychiatrist and treatment adherence. The
same 2 factors were associated with higher
odds of housing, and presence of substance
use disorder was associated with lower odds
of housing at 6-month follow-up.
Young homeless people have high rates of
psychiatric disorders and related complex
needs. However, they often find it difficult to
access mainstream mental health services.
The aim of this study was to establish the and
whether this is predicted by variables in young
people's profiles. Young people reported a
range of previous adversities and service
contacts, and high HoNOS and risk scores.
There was significant improvement on most
HoNOS items for those who attended more

To investigate whether substance abuse is a direct factor in the explanation of homelessness or one that operates indirectly
through disaffiliation and human capital processes to place individuals at greater risk of the condition. Analysis of several
46
nested models of homelessness links substance abuse only indirectly to loss of domicile, primarily through its impact on
social and institutional affiliations. Contrary to expectations, substance abuse did not impact homelessness indirectly by
diminishing the accumulation of human capital. CONCLUSIONS: The role of disaffiliation as a proximate cause of
homelessness was confirmed. This locates the phenomenon within the context of society itself, as a direct result of a
breakdown in the social bonds necessary for human community. Substance abuse plays a critical role in this breakdown,
negatively influencing social as well as institutional relationships

deinstitutionalization was a major factor leading to the increase in homelessness in Germany, but the extent to which
established psychiatric outpatient services are providing sufficient support for their clientele is debated. It is argued that the
problems of homeless people can be overcome only be a functional network of different, responsible, and accountable
services.
Reviews factors associated with homelessness. The loss of employment and income are significant variables involved in
homelessness. During the early decades, most of the homeless were single men with little education and skills who were
unemployed. However, recent reports indicate an increasing number of families in the homeless population. Estimates of the
number of homeless people range between 300,000 and 3,000,000. Inconsistencies are observed in the public policies, most
policymakers dealing with homelessness as a local concern. Homelessness is found to be associated with mental health and
unemployment. It can be interpreted as a generalizational problem, an extreme end of poverty syndrome, fueled by poor
planning and the lack of incentives to find a job
System dynamics models help explain why intuitive, well-intentioned solutions to social problems go awry when introduced

youth behavior and shelter usage. Together, the model and supporting evidence imply that simple linear thinking may guide
policy expansion to the detriment of homeless youth. Shelters provide incentives for other service systems to neglect difficult
cases, which raises serious questions about the efficacy of the shelter system. This model provides common ground upon
which practitioners, administrators, policymakers, and research communities can consider the impact and effectiveness of
policy and service. Furthermore, the model challenges these communities to bring dynamic system considerations to their
work
Notes that there is convincing evidence that homeless people have higher rates of both mental health and substance misuse
problems than the general population, in addition to lowered access to services and other helping resources. It is proposed
that a model of care which includes designated, well-trained, and well-supervised workers who can work effectively across
47
the various domains of mental health, substance misuse, and housing will be the main future direction. The author argues
that it is important to adopt a holistic (and pragmatic) view as to what the targets of treatment should be, and that
therapists need very high levels of skill in engagement. In addition, the assessment of co-existing mental health and
alcohol/other drug use problems in people who are also homeless should follow a similar process as for other clients.
However, there are important individual barriers and organizational issues that need to be addressed. The author concludes
by suggesting that there are four areas from which treatment ideas can be drawn: substance misuse, mental health
generally, assertive outreach in particular, and housing.
