Psychological Disorders
I felt the need to clean my room … spent four to five
hour at it … At the time I loved it but then didn't want
to do it any more, but could not stop … The clothes
hung … two fingers apart …I touched my bedroom
wall before leaving the house … I had constant anxiety
… I thought I might be nuts.
Marc, diagnosed with
obsessive-compulsive disorder
(from Summers, 1996)

Psychological Disorders
People are fascinated by the exceptional, the
unusual, and the abnormal. This fascination
may be caused by two reasons:
1.
During various moments we feel, think, and act
like an abnormal individual.
2.
Psychological disorders may bring unexplained
physical symptoms, irrational fears, and suicidal
thoughts.
9
Psychological Disorders
To study the abnormal is the best way of
understanding the normal.
William James (1842-1910)
1.
26.2 percent of Americans ages 18 and older — about one in four adults — suffer from a diagnosable mental
disorder in a given year
2.
Nearly half (45 percent) of those with any mental disorder meet criteria for 2 or more disorders,
with severity strongly related to comorbidity
3.
There are 450 million people suffering from psychological disorders (WHO, 2004).
4.
Depression and schizophrenia exist in all cultures of the world.

Is Attention-Deficit/
Hyperactivity Disorder (ADHD)
a disorder?
 Is it deviant? Do some people have a level of
inattentiveness, impulsiveness, or restlessness that
goes beyond laziness or immaturity?
 Is it distressful? Is the person enjoying being
energetic, or are they frustrated that they can’t sustain
focus?
 Is there dysfunction? Are the symptoms harmless
fun, or do they negatively impact work and
relationships?
• Andrew has led a turbulent life. As a young child, he
skipped school more often than he attended. When he did
attend, he was a frequent behavior problem, often getting
into fights with other boys. He was finally expelled from
school altogether after stabbing another student in his high
school class. Since then he has not held a job for any
length of time. Soon after his expulsion, he began
supplementing his income by breaking into homes and
stealing whatever he could get his hands on. However, he
appears to feel no guilt about this behavior. Although he
has never been in a committed relationship, he has several
children, whom he never sees, due partly to the fact that he
frequently moves from town to town. Despite these
characteristics, Andrew is a colorful and entertaining
person and has a certain charm. If asked, he will tell you
that he is quite happy with his current life-style.

• Barbara was generally a happy child and had many friends
in high school. She made very good grades and decided to
go on to college and then to law school. After her first year
of law school, she began to notice periods of “feeling
down.” At first she ignored this, but after a year or so,
these episodes began to get worse. When she started
paying more attention, she noticed that the episodes
usually began about a week before her period and ended a
few days after her period began. In addition to feeling
depressed during that time, she also was overly sensitive to
criticism. Often, her appetite would increase, and she
would especially crave sweets. Sometimes she found it
difficult to concentrate on her studies during this time, and
she often lacked the energy to do much of anything except
watch television.
14
• Charles is the third of seven children. He attended school in
the suburbs of a large city, where he made average grades.
He dated a bit in high school and had several close friends.
During vacations, he worked in his father’s garage, learning
all he could about automobiles. After high school, Charles
took a job as a mechanic in the garage. However, Charles
was beginning to feel different from his co-workers. He
began to realize that he was attracted to one of his customers,
a man with whom he had gone to school. When Charles
realized this, he became very confused and felt angry with
himself for having such feelings. Although he tried to
convince himself that the feelings would go away over time,
they did not, and Charles finally admitted to himself that he
was a homosexual. Currently, he is in a monogamous
relationship with another man but is afraid to admit his
sexual orientation to friends or family, for fear of their
reaction. He often finds himself preoccupied with trying to 15
find ways to hide his orientation from them.
• Eric was born in a rural town in the Midwest. He made
average grades in school and decided after graduation to
purchase a farm in the area and raise corn. He very much
enjoyed this lifestyle and did quite well. One day, while
working in the field, an accident with a combine caused
Eric to be rushed to the hospital. While doctors were able
to save his life, they were not able to save his legs. Eric is
now confined to a wheelchair. It has been a year since the
accident and he is in a great deal of pain, which is partially
controlled by morphine, which his doctor has prescribed.
However, his thinking remains quite rational, and he has
been able to do some work helping with the books at his
parents’ store. He does not enjoy this work and misses his
previous activity. Recently, he confided in his doctor that
he does not feel that his new life is worth living, and he has
decided that he would like to end it all.

Psychological Disorders
• Psychological Disorder
– a “harmful dysfunction” in which behavior is
judged to be:
• Deviance – behavior that deviates from societies
norms.
• Distress – negative feelings toward themselves
• Dysfunction – maladaptive behavior patterns.
• Danger – usually positively reinforces behavior.
17
Defining Psychological Disorders
Mental health workers view psychological
disorders as persistently harmful thoughts,
feelings, and actions.
When behavior is deviant, distressful, dangerour,
and dysfunctional psychiatrists and psychologists
label it as disordered (Comer, 2004).
18
Deviant, Distressful & Dysfunctional
Carol Beckwith
1. Deviant behavior
(going naked) in one
culture may be
considered normal,
while in others it may
lead to arrest.
2. Deviant behavior must
accompany distress.
3. If a behavior is
dysfunctional it is
clearly a disorder.
In the Wodaabe tribe men
wear costumes to attract
women. In Western society
this would be considered
abnormal.
19
Understanding Psychological
Disorders
Ancient Treatments of psychological disorders
include trephination, exorcism, being caged like
animals, being beaten, burned, castrated,
mutilated, or transfused with animal’s blood.
John W. Verano
Trephination (boring holes in the skull to remove evil forces)

Medical Perspective
Philippe Pinel (1745-1826) from France, insisted
that madness was not due to demonic possession,
but an ailment of the mind.

Medical Model
When physicians discovered that syphilis led to
mental disorders, they started using medical models
to review the physical causes of these disorders.
1.
2.
3.
4.
Etiology: Cause and development of the
disorder.
Diagnosis: Identifying (symptoms) and
distinguishing one disease from another.
Treatment: Treating a disorder in a psychiatric
hospital.
Prognosis: Forecast about the disorder.
22
Biopsychosocial Perspective
Assumes that biological, socio-cultural, and
psychological factors combine and interact to
produce psychological disorders.
23
Classifying Psychological Disorders
The American Psychiatric Association rendered
a Diagnostic and Statistical Manual of Mental
Disorders (DSM) to describe psychological
disorders.
The most recent edition, DSM 5 describes 400
psychological disorders compared to 60 in the
1950s.
24
Goals of DSM
1.
2.
Describe (400) disorders.
Determine how prevalent the
disorder is.
Disorders outlined by DSM 5 are reliable.
Therefore, diagnoses by different professionals
are similar.
Others criticize DSM-5 for “putting any kind of
behavior within the compass of psychiatry.”
25
Labeling Psychological Disorders
1. Critics of the DSM-IV argue that labels may
stigmatize individuals.
Elizabeth Eckert, Middletown, NY. From L. Gamwell and
N. Tomes, Madness in America, 1995. Cornell University Press.

26
Labeling Psychological Disorders
2. Labels may be helpful for healthcare
professionals when communicating with
one another and establishing therapy.
27
Labeling Psychological Disorders

3. “Insanity” labels
raise moral and
ethical questions
about how society
should treat people
who have
disorders and have
committed crimes.

• Pretend the following description of Tom W. was written by a
clinical psychologist 5 years ago, when Tom was a senior in high
school. Please read it carefully before responding to the question
below.
• Tom W. is of high intelligence, although lacking in true
creativity. He has a need for order and clarity, and for neat
and tidy systems in which every detail finds its appropriate
place. His writing is rather dull and mechanical,
occasionally enlivened by somewhat corny puns and
flashes of imagination of the sci-fi type. He has a strong
drive for competence. He seems to have little feeling and
little sympathy for other people and does not enjoy
interacting with others. Self-centered, he nonetheless has a
deep moral sense.
• Today, Tom is a mental patient in a state hospital. Might that outcome
have been predicted when Tom was a senior in high school? On what
basis?

Anxiety statistics
Anxiety and anxiety related conditions negatively impact individuals, and our
society:
•40 million people in the U.S. will experience an impairment because of an anxiety
condition this year.
•Only 4 million will receive treatment, and of those, only 400,000 will receive
proper treatment.
•Those who experience anxiety and stress have a very high propensity for drug
abuse and addictions.

65% of North Americans take prescription medications daily, 43% take mood altering prescriptions
regularly.
There were over 3.3 Billion prescriptions filled in America in 2002 (12 times the U.S’s population that’s 12 prescriptions for every man, woman, and child in the U.S. that year).
Paxil and Zoloft (two of the more popular anti-anxiety medications) ranked 7th and 8th in the top ten
prescribed medications in the US (these two medications totaled almost $5 Billion in sales in 2002).
Recreational drugs are also used to cope with anxiety. 42% of young adults in America regularly use
recreational drugs (National Institute on Drug Abuse)
Alcohol is commonly used to cope with anxiety. 72% of Canadians consume alcohol each year.

On November 1983, Pearl Pizzamiglio, age 60, was working as a hotel
clerk when Michael Steward handed her a paper bag with a note: “Don’t
say a word. Put all the money in this bag and no one will get hurt.”
Pizzamiglio complied, Stewart fled, and the police were called. Two hours
later Pizzamiglio was dead of heart failure. She had had no history of heart
trouble and a jury, convinced that Stewart had scared her to death, later
convicted him of murder.
On Memorial Day weekend, 1988, Barbara Reyes, 40, was floating on a raft
when a man on a jet ski roared within a foot of her. Panicked, she paddled
to the shore, collapsed, and died. The skier was arrested and charged with
involuntary manslaughter.
Omar Torrijos, Panama’s former dictator, reportedly amused himself by
killing a prisoner with an unloaded gun; blanks, apparently, were enough to
frighten the victim to death.
An elderly man sitting on his lawn collapsed and died when a car jumped
the curb and seemed to head straight for him.
An 45-year-old man reportedly died of fright as he stepped to the dais to
give a speech.

GAD: Generalized
Anxiety Disorder
 Emotional-cognitive
symptoms include
worrying, having anxious
feelings and thoughts about
many subjects, and
sometimes “free-floating”
anxiety with no attachment
to any subject. Anxious
anticipation interferes with
concentration.
 Physical symptoms include
autonomic arousal,
trembling, sweating,
fidgeting, agitation, and
sleep disruption.
Panic Disorder:
“I’m Dying”
A panic attack is not just an
“anxiety attack.” It may include:
 many minutes of intense dread
or terror.
 chest pains, choking,
numbness, or other frightening
physical sensations. Patients
may feel certain that it’s a heart
attack.
 a feeling of a need to escape.
Panic disorder refers to repeated
and unexpected panic attacks, as
well as a fear of the next attack,
and a change in behavior to avoid
panic attacks.
Specific Phobia
A specific phobia is more than just
a strong fear or dislike. A specific
phobia is diagnosed when there is
an uncontrollable, irrational,
intense desire to avoid the some
object or situation. Even an image
of the object can trigger a reaction-“GET IT AWAY FROM ME!!!”-the uncontrollable, irrational,
intense desire to avoid the object
of the phobia.
Phobia
Marked by a persistent and irrational fear of an
object or situation that disrupts behavior.

Other Anxiety Disorders
• Separation Anxiety: is persistent fear or
anxiety about harm coming to attachment
figures and events that could lead to loss of
or separation from attachment figures and
reluctance to go away from attachment
figures, as well as nightmares and physical
symptoms of distress
46
Other Anxiety Disorders
• Social Anxiety: fearful or anxious about or
avoidant of social interactions and situations
that involve the possibility of being
scrutinized
• Selective Mutism: consistent failure to
speak in social situations in which there is
an expectation to speak (e.g., school) even
though the individual speaks in other
situations.

Understanding Anxiety Disorders:
Explanations from Different Perspectives
Psychodynamic/
Freudian:

Observational
learning:
worrying like
mom
Classical
conditioning:
overgeneralizing
a conditioned
response
Cognitive
appraisals:
uncertainty is

Operant
conditioning:

Evolutionary:

avoiding danger
Understanding Anxiety Disorders:
Freudian/Psychodynamic
Perspective
 Sigmund Freud felt that
anxiety stems from
repressed childhood
impulses, socially
inappropriate desires, and
emotional conflicts.
 We repress/bury these
issues in the unconscious
mind, but they still come
up, as anxiety.

Classical
Conditioning and
Anxiety
In the experiment
by John B.
Watson and Rosalie Rayner in
1920, Little Albert learned to
feel fear around a rabbit
because he had been
conditioned to associate the
bunny with a loud scary noise.
 Sometimes, such a conditioned
response becomes
overgeneralized. We may begin
to fear all animals, everything
fluffy, and any location where
we had seen those, or even fear
that those items could appear
soon along with the noise.
 The result is a phobia or
generalized anxiety.
Operant Conditioning
and Anxiety
 We may feel anxious in a
situation and make a decision
to leave. This makes us feel
better and our anxious
avoidance was just reinforced.
 If we know we have locked a
door but feel anxious and
compelled to re-check,
rechecking will help us
temporarily feel better.
 The result is an increase in
anxious thoughts and
behaviors.
Observational
Learning and
Anxiety
 Experiments with humans
and monkeys show that
anxiety can be acquired
through observational
learning. If you see
someone else avoiding or
fearing some object or
creature, you might pick
up that fear and adopt it
even after the original
scared person is not
around.
 In this way, fears get
passed down in families.
Cognition and
Anxiety
 Cognition includes worried
thoughts, as well as
interpretations, appraisals,
beliefs, predictions, and
ruminations.
 Cognition includes mental
habits such as
hypervigilance (persistently
watching out for danger).
This accompanies anxiety in
PTSD.
 In anxiety disorders, such
cognitions appear
repeatedly and make
anxiety worse.
Examples of Cognitions that can
Worsen Anxiety:
Cognitive errors, such as believing that we
can predict that bad events will happen
Irrational beliefs, such as “bad things don’t
happen to good people, so if I was hurt, I
must be bad”
Mistaken appraisals, such as seeing aches as
diseases, noises as dangers, and strangers as
threats
Misinterpretations of facial expressions and
actions of others, such as thinking “they’re
talking about me”
Biology and Anxiety:
An Evolutionary Perspective
1. Human phobic objects: 2. Similar but non-phobic
Snakes objects:
Heights Fish
Closed spaces Low places
Darkness Open spaces
light
3. Dangerous yet non-phobicBright
subjects:
We are likely to become cautious about, but not phobic about:
Guns
Electric wiring
McDonalds
 Evolutionary psychologists believe that ancestors
prone to fear the items on list #1 were less likely to
die before reproducing.
 There has not been time for the innate fear of list #3
(the gun list) to spread in the population.
Biology and Anxiety: Genes
 Studies show that
identical twins, even
raised separately,
develop similar
phobias (more similar
than two unrelated
people).
 Some people seem to
have an inborn highstrung temperament,
while others are more
easygoing.
 Temperament may
be encoded in our
genes.
Genes and
Neurotransmitters
17 Genes regulate are
associated with Anxiety
People with anxiety have
problems with a gene associated
with levels of serotonin, a
neurotransmitter involved in
regulating sleep and mood.
People with anxiety also have a
gene that triggers high levels of
glutamate, an excitatory
neurotransmitter involved in the
brain’s alarm centers.
Biology and Anxiety: The Brain
 Traumatic
experiences can burn
fear circuits into the
amygdala; these
circuits are later
triggered and
activated.
 Anxiety disorders
include overarousal
of brain areas
involved in impulse
control and habitual
behaviors.
The OCD brain shows extra
activity in the ACC, which
monitors our actions and checks
for errors.
ACC = anterior cingulate gyrus

The Biological Perspective
• Natural Selection has led our ancestors to
learn to fear snakes, spiders, and other
animals. Therefore, fear preserves the species.
• Twin studies suggest that our genes may be
partly responsible for developing fears and
anxiety. Twins are more likely to share
phobias.
• 17 genes that appear to be expressed with
anxiety symptoms:
–
–
Serotonin levels – sleep and mood
Glutamate levels - overactivity
59
The Biological Perspective
S. Ursu, V.A. Stenger, M.K. Shear, M.R. Jones, & C.S. Carter (2003). Overactive action
monitoring in obsessive-compulsive disorder. Psychological Science, 14, 347-353.
Generalized anxiety,
panic attacks, and even
OCD are linked with
brain circuits like the
anterior cingulate cortex.
Linked to amygdala and
processes the salience of
emotions (picks out
things that are important
in the environment).
Anterior Cingulate Cortex
of an OCD patient.
60
Auditory and visual stimuli:
sights and sounds are processed first
by the thalamus, which filter the
incoming cues and shunts them
either to the amygdala or the cortex.
Olfactory and tactile stimuli:
smells and touch sensations bypass
the thalamus, taking a shortcut to the
amygdala. Smells, often evoke
stronger memories or feelings than
do sights or sounds.
Amygdala: the emotional core of
the brain, primary roles of triggering
the fear response. Information that
passes through the amygdala is
tagged with emotional significance.
Hippocampus: vital to storing the
raw information coming in from the
senses, along with the emotional
baggage attached to the data during
their trip through the amygdala.
61
Obsessive-Compulsive and
Related Disorders
• OCD
• Body Dysmorphic
Disorder
• Hoarding Disorder
• Trichotillomania
(hair pulling)
• Excoriation (skinpicking)
62
Diagnostic Criteria - OCD
•
Presence of obsessions, compulsions, or both:
• Obsessions are defined by
– Recurrent and persistent thoughts, urges, or images that are
experienced, at some time during the disturbance, as intrusive and
unwanted, and that in most individuals cause marked anxiety or distress.
– The individual attempts to ignore or suppress such thoughts, urges, or
images, or to neutralize them with some other thought or action (i.e., by
performing a compulsion).
• Compulsions are defined by
– Repetitive behaviors (e.g., hand washing, ordering, checking) or mental
acts (e.g., praying, counting, repeating words silently) that the individual
feels driven to perform in response to an obsession or according to rules
that must be applied rigidly.
– The behaviors or mental acts are aimed at preventing or reducing anxiety
or distress, or preventing some dreaded event or situation; however, these
behaviors or mental acts are not connected in a realistic way with what 63
they are designed to neutralize or prevent, or are clearly excessive.
Obsessive-Compulsive Disorder
Persistence of unwanted thoughts (obsessions)
and urges to engage in senseless rituals
(compulsions) that cause distress.

Depressive Disorders
Emotional extremes of mood disorders come
in two principal forms.
•Approximately 20.9 million American adults, or about 9.5 percent of the U.S. population
age 18 and older in a given year, have a mood disorder.
•The median age of onset for mood disorders is 30 years.
•Depressive disorders often co-occur with anxiety disorders and substance abuse. (NIMH,
2010)
•90,000 college students surveyed – 44% responded that on more than one occasion they
felt “so depressed it was difficult to function”
67
Disruptive Mood Dysregulation
Disorder
•
•
•
•
•
•
•
•
•
Severe recurrent temper outbursts manifested verbally (e.g., verbal rages) and/or
behaviorally (e.g., physical aggression toward people or property) that are grossly out of
proportion in intensity or duration to the situation or provocation.
The temper outbursts are inconsistent with developmental level.
The temper outbursts occur, on average, three or more times per week.
The mood between temper outbursts is persistently irritable or angry most of the day,
nearly every day, and is observable by others (e.g., parents, teachers, peers).
Criteria A–D have been present for 12 or more months. Throughout that time, the
individual has not had a period lasting 3 or more consecutive months without all of the
symptoms in Criteria A–D.
Criteria A and D are present in at least two of three settings (i.e., at home, at school,
with peers) and are severe in at least one of these.
The diagnosis should not be made for the first time before age 6 years or after age 18
years.
By history or observation, the age at onset of Criteria A–E is before 10 years.
There has never been a distinct period lasting more than 1 day during which the full
symptom criteria, except duration, for a manic or hypomanic episode have been met. 68

•
•
Premenstrual Dysphoric
Disorder
In the majority of menstrual cycles, at least five symptoms must be present in the final week before the
onset of menses, start to improve within a few days after the onset of menses, and become minimal or
absent in the week postmenses.
One (or more) of the following symptoms must be present:
– Marked affective lability (e.g., mood swings; feeling suddenly sad or tearful, or increased
sensitivity to rejection).
– Marked irritability or anger or increased interpersonal conflicts.
– Marked depressed mood, feelings of hopelessness, or self-deprecating thoughts.
– Marked anxiety, tension, and/or feelings of being keyed up or on edge.
One (or more) of the following symptoms must additionally be present, to reach a total of five symptoms
when combined with symptoms from Criterion B above.
– Decreased interest in usual activities (e.g., work, school, friends, hobbies).
– Subjective difficulty in concentration.
– Lethargy, easy fatigability, or marked lack of energy.
– Marked change in appetite; overeating; or specific food cravings.
– Hypersomnia or insomnia.
– A sense of being overwhelmed or out of control.
– Physical symptoms such as breast tenderness or swelling, joint or muscle pain, a sensation of
“bloating,” or weight gain.
69
Major Depressive Disorder
Depression is the “common cold” of
psychological disorders. In a year, 5.8% of men
and 9.5% of women report depression
worldwide (WHO, 2002).

Major Depressive Disorder
•
•
•
•
Five (or more) of the following symptoms have been present during the same
2-week period and represent a change from previous functioning; at least one
of the symptoms is either (1) depressed mood or (2) loss of interest or
pleasure.
Depressed mood most of the day, nearly every day, as indicated by either
subjective report (e.g., feels sad, empty, hopeless) or observation made by
others (e.g., appears tearful). (Note: In children and adolescents, can be
irritable mood.)
Markedly diminished interest or pleasure in all, or almost all, activities most of
the day, nearly every day (as indicated by either subjective account or
observation).
Significant weight loss when not dieting or weight gain (e.g., a change of more
than 5% of body weight in a month), or decrease or increase in appetite nearly
every day. (Note: In children, consider failure to make expected weight gain.)
71
Major Depressive Disorder
•
•
•
•
•
•
•
•
Insomnia or hypersomnia nearly every day.
Psychomotor agitation or retardation nearly every day (observable by others, not merely
subjective feelings of restlessness or being slowed down).
Fatigue or loss of energy nearly every day.
Feelings of worthlessness or excessive or inappropriate guilt (which may be delusional)
nearly every day (not merely self-reproach or guilt about being sick).
Diminished ability to think or concentrate, or indecisiveness, nearly every day (either by
subjective account or as observed by others).
Recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation without a
specific plan, or a suicide attempt or a specific plan for committing suicide.
The symptoms cause clinically significant distress or impairment in social, occupational,
or other important areas of functioning.
The episode is not attributable to the physiological effects of a substance or to another
medical condition.
72
College & Depression
•
•
•
Aaron Beck, a leading investigator of depression, suggests that college students may
be especially prone to psychological problems because they simultaneously
experience all the transitions that are major stresses in adulthood.
Entering college, they lose family, friends, and familiar surroundings and are provided
no ready made substitutes. Furthermore, while in high school, they were the most able
students; in college they must compare their own abilities with equally able students.
Research indicates that students who exhibit optimism as they enter college
develop more social support and experience a lowered risk of depression.
Moreover, students’ frequent misperception of these stresses may be as important a
cause of depression as the stresses themselves. While they do not hallucinate their
problems of academic or social adjustment, they often inflate the importance of
temporary setbacks and misjudge the severity of rejections. They may
overestimate academic difficulties on the basis of one mediocre grade. They may
grieve over their social isolation, even though they often have at least some caring and
supportive friends. Their pessimism and dissatisfaction may lead to clinical depression
that in turn interferes with actual performance. A vicious cycle is created in which
misperceptions of academic and social difficulties result in still poorer grades and
greater
73
• Studies suggest that perhaps 40 to 50
percent of college students have suicidal
thoughts at one time or another and that as
many as 15 percent may have actually.
• Edwin Schneidman presents the following
in the belief that knowledge of these
characteristics may help the general public
and mental health professionals reduce
suicide rates.

alternation between depression and mania
signals bipolar disorder.

Bipolar I
• The essential feature of a manic episode is
a distinct period during which there is an
abnormally, persistently elevated,
expansive, or irritable mood and
persistently increased activity or energy that
is present for most of the day, nearly every
day, for a period of at least 1 week.
76
Bipolar I -Diagnostic Criteria
•
For a diagnosis of bipolar I disorder, it is necessary to meet the following criteria for a manic episode. The
manic episode may have been preceded by and may be followed by hypomanic or major depressive episodes.
Manic Episode
•
•
A distinct period of abnormally and persistently elevated, expansive, or irritable mood and
abnormally and persistently increased goal-directed activity or energy, lasting at least 1
week and present most of the day, nearly every day (or any duration if hospitalization is
necessary).
During the period of mood disturbance and increased energy or activity, three (or more) of the
following symptoms (four if the mood is only irritable) are present to a significant degree and
represent a noticeable change from usual behavior:
– Inflated self-esteem or grandiosity.
– Decreased need for sleep (e.g., feels rested after only 3 hours of sleep).
– More talkative than usual or pressure to keep talking.
– Flight of ideas or subjective experience that thoughts are racing.
– Distractibility (i.e., attention too easily drawn to unimportant or irrelevant external stimuli),
as reported or observed.
– Increase in goal-directed activity (either socially, at work or school, or sexually) or
psychomotor agitation (i.e., purposeless non-goal-directed activity).
– Excessive involvement in activities that have a high potential for painful consequences (e.g.,
77
engaging in unrestrained buying sprees, sexual indiscretions, or foolish business
investments).
Manic state of a bipolar disorder
•
When I start going into a high, I no longer feel like an ordinary housewife.
Instead, I feel organized and accomplished, and I begin to feel I am my most
creative self. I can write poetry easily. I can compose melodies without effort.
I can paint. My mind feels facile and absorbs everything. I have countless
ideas about improving the conditions of mentally retarded children, how a
hospital for these children should be run, what they should have around them
to keep them happy and calm and unafraid. I see myself as being able to
accomplish a great deal for the good of people. I have countless ideas about
how the environmental problem could inspire a crusade for the health and
betterment of everyone. I feel able to accomplish a great deal for the good of
my family and others. I feel pleasure, a sense of euphoria or elation. I want it
to last forever. I don’t seem to need much sleep. I’ve lost weight and feel
healthy, and I like myself. I’ve just bought six new dresses, in fact, and they
look quite good on me. I feel sexy and men stare at me. Maybe I’ll have an
affair, or perhaps several. I feel capable of speaking and doing good in politics.
I would like to help people with problems similar to mine so they won’t feel
hopeless. (Fieve, 1975, p. 17)
78
Bipolar II
•
Bipolar II disorder is characterized by a clinical course of recurring mood episodes consisting of one or more major
depressive episodes (Criteria A–C under “Major Depressive Episode”) and at least one hypomanic episode (Criteria
A–F under “Hypomanic Episode”).
79
Hypomanic episode
• Not a disorder in itself, but rather is a description of a part
of a type of bipolar II disorder.
• Associated with a change in functioning that is
uncharacteristic of the person.
• Hypomanic episodes have the same symptoms as manic
episodes with two important differences:
– (1) the mood usually isn’t severe enough to cause problems
with the person working or socializing with others (e.g., they
don’t have to take time off work during the episode), or to require
hospitalization; and
– (2) there are never any psychotic features present in a hypomanic
episode.

Bipolar Disorder
Many great writers, poets, and composers
suffered from bipolar disorder. During their
manic phase creativity surged, but not during
their depressed phase.

Suicide and Self-Injury
 Every year, 1 million people commit suicide, giving
up on the process of trying to cope and improve their
emotional well-being.
 This can happen when people feel frustrated, trapped,
isolated, ineffective, and see no end to these feelings.
 Non-suicidal self-injury has other functions such as

An Evolutionary Perspective on the
Biology of Depression
 Depression, in its milder, nondisordered form, may have
had survival value.
 Under stress, depression is
social-emotional hibernation.
It allows humans to:
 conserve energy.
 avoid conflicts and other
risks.
 let go of unattainable goals.
 take time to contemplate.
Biology of Depression: Genetics
Evidence of genetic influence on depression:
1. DNA linkage analysis reveals depressed gene regions
2. twin/adoption heritability studies
Biology of Depression: The Brain
 Brain activity is diminished in depression and increased in
mania.
 Brain structure: smaller frontal lobes in depression and
fewer axons in bipolar disorder
 Brain cell communication (neurotransmitters):
 more norepinephrine (arousing) in mania, less in
depression
 reduced serotonin in depression

Zung Depression Scale
• The authors do not provide specific norms but indicate that
“most respondents score in the lower range.” The specific scale
items introduce four important components of depression:
• Items 2 and 9 reflect the presence of negative affect; items 3
and 6 suggest the absence of positive affect; 7, 8, and 10
indicate interpersonal difficulty; and items 1, 4, and 5 assess
“somatic” difficulties.
• Handout 16–14, the Zung Self-Rating Depression Scale, is one
of the most widely used measures of depression.
• In scoring, students should reverse their responses to items 2, 5,
6, 11, 12, 14, 16, 17, 18, and 20 (that is, 1 = 4, 2 = 3, 3 = 2, 4 =
1). They should then add all the numbers to obtain a total
score, which can range from 20 to 80.
• Scores from 50 to 59 suggest mild to moderate depression, from
60 to 69 indicate moderate to severe depression, and 70 and 96
above indicate severe depression.
1. Unendurable psychological pain. Suicide is not an act of hostility or revenge
but a way of switching off unendurable and inescapable pain. If you reduce
their level of suffering, even just a little, suicidal people will choose to live.
2. Frustrated psychological needs. Needs for security, achievement, trust, and
friendship are among the important ones not being met. Address these
psychological needs and the suicide will not occur. Although there are
pointless deaths, there is never a “needless” suicide.
3. The search for a solution. Suicide is never done without purpose. It is a way
out of a problem or crisis and seems to be the only answer to the question:
“How do I get out of this?”
4. An attempt to end consciousness. Suicide is both a movement away from pain
and a movement to end consciousness. The goal is to stop awareness of a
painful existence.
5. Helplessness and hopelessness. Underneath all the shame, guilt, and loss of
effectiveness is a sense of powerlessness. There is the feeling that no one can
help and nothing can be done except to commit suicide.

Constriction of options. Instead of looking for a variety of answers,
suicidal people see only two alternatives: a total solution or a total
cessation. All other options have been driven out by pain. The goal of
the rescuer should be to broaden the suicidal person’s perspective.
Ambivalence. Some ambivalence is normal, but for the suicidal person
ambivalence is only between life and death. In the typical case, a
person cuts his or her own throat and calls for help simultaneously. The
rescuer can use this ambivalence to shift the inner debate to the side of
life.
Communication of intent. About 80 percent of suicidal people give
family and friends clear clues about their intention to kill themselves.
Departure. Quitting a job, running away from home, leaving a spouse
are all departures, but suicide is the ultimate escape. It is a plan for a
radical, permanent change of scene.
Lifelong coping patterns. To spot potential suicides, one must look to
earlier episodes of disturbance, to the person’s style of enduring pain,
and to a general tendency toward “either/or” thinking. Often, there has
been a style of problem solving that might be characterized as “cut and
run.”
98
Women experience depression at roughly
twice the rate as men. What might account for
this large difference?
• Is it possible that women are simply more willing to admit to
being depressed than men are? As a researcher, how could you
assess rates of depression in a way that minimized this potential
reporting problem? To answer this question: a) describe the
method you would choose to collect your data; b) explain why
you chose that method; and c) describe the specific measures
you would take to minimize the anticipated reporting problem.
• What biological factors might account for women's greater
susceptibility to depression?
• What social factors might account for women's greater
susceptibility to depression?
• Young boys and girls have been shown to suffer from
depression equally until they reach adolescence. At that point,
depression becomes much more common in women. What might
99
account for this change?
Dissociative Disorder
Common denominator is the “fragmentation”
of personality – a sense that parts of personality
have detached (dissociated) from others.
Symptoms
1. Having a sense of being unreal.
2. Being separated from the body.
3. Watching yourself as if in a movie.

101
Dissociative Disorder
• Non-psychotic Fragmentation of the Personality
(note: all diagnosis is disputed) – essential feature is a disruption in the
usually integrated functions of consciousness, memory identity, or
perception.
– Dissociative amnesia – memory loss due to stress
– Dissociative fugue – loss of identity which leads to
fugue (flight)
– Depersonalization disorder – mind / body are separated.
Dream state / Near death experiences
– Dissociative Identity disorder

DID Critics
Critics argue that the diagnosis of DID
increased in the late 20th century. DID has
not been found in other countries.
Critics’ Arguments
1. Role-playing by people open to a
therapist’s suggestion.
2. Learned response that reinforces
reductions in anxiety.
104
Is DID the same as Schizophrenia?
• NO –
– DID is sometimes called a “split personality”
– Schizophrenia’s split is based on reality, not a
fracturing of personalities.
105
106
Schizophrenia
If depression is the common cold of
psychological disorders, schizophrenia is the
cancer.
Nearly 1 in a 100 suffer from schizophrenia, and
throughout the world over 24 million people
suffer from this disease (WHO, 2002).
Schizophrenia strikes young people as they
mature into adults. It affects men and women
equally, but men suffer from it more severely
than women.

115
Delusional Disorder
• Erotomanic type: This subtype applies when the central theme of the
delusion is that another person is in love with the individual.
• Grandiose type: This subtype applies when the central theme of the
delusion is the conviction of having some great (but unrecognized)
talent or insight or having made some important discovery.
• Jealous type: This subtype applies when the central theme of the
individual’s delusion is that his or her spouse or lover is unfaithful.
• Persecutory type: This subtype applies when the central theme of the
delusion involves the individual’s belief that he or she is being
conspired against, cheated, spied on, followed, poisoned or drugged,
maliciously maligned, harassed, or obstructed in the pursuit of longterm goals.
• Somatic type: This subtype applies when the central theme of the
116
delusion involves bodily functions or sensations.
Disorganized & Delusional Thinking
Many psychologists believe disorganized
thoughts occur because of selective attention
failure (fragmented and bizarre thoughts).
117
Disturbed Perceptions
A schizophrenic person may perceive things
that are not there (hallucinations). Frequently
such hallucinations are auditory and lesser
visual, somatosensory, olfactory, or gustatory.

118
Inappropriate Emotions & Actions
A schizophrenic person may laugh at the news
of someone dying or show no emotion at all
(apathy).
Patients with schizophrenia
may continually rub an arm,
rock a chair, or remain
motionless for hours
(catatonia).
119
Positive and Negative Symptoms
Schizophrenics have inappropriate symptoms
(hallucinations, disorganized thinking, deluded
ways) that are not present in normal
individuals (positive symptoms).
Schizophrenics also have an absence of
appropriate symptoms (apathy, expressionless
faces, rigid bodies) that are present in normal
individuals (negative symptoms).
120
Chronic and Acute Schizophrenia
When schizophrenia is slow to develop
(chronic/process) recovery is doubtful. Such
schizophrenics usually display negative
symptoms.
When schizophrenia rapidly develops
(acute/reactive) recovery is better. Such
schizophrenics usually show positive
symptoms.
