Treatment of Psychological Disorders History Psychological Therapies Biological Therapies Effectiveness Specific Disorder-Treatment Matches Old-Fashioned Causes & “Cures”  Possession by demons  Prehistoric  Trephination  In league with Satan  Up to 1700    Exorcism Torture Starvation  Humor imbalance  From Greeks until 1800s    Bloodletting Purging Whirling  Illness  Middle ages until 1800’s  Confinement in asylums, often dungeon-like prisons History: 1800’s to 1950  Humanitarian Reform Movement (1800’s) “Inmates” begin to be housed in more standard living conditions  Hysteria and general paresis  Hysteria cured by Freud (1890’s)    Psychological approach to treatment General paresis caused by syphilis (1913)  Neuropsychiatric disorder affecting central nervous system – Presents with psychotic-like symptoms  Biological approach to treatment  Mental hospital inpatient population grows to 600,000 in 1950’s (see slide 5) History: 1950’s to present  Discovery of antipsychotics in 1950’s  Deinstitutionalization begins in 1960’s and continues until today  40,000 mental hospital inpatients remain (see slide 5)  Some reasons for deinstitutionalization  Introduction of antipsychotics  Criticism of mental hospitals  Community care movement  Reduce costs to state governments  Some negative consequences of deinstitutionalization  16% - 50% of incarcerated prisoners have a mental disorder   The range in percentages depend on criteria for mental disorder classification 1/3-1/2 of homeless have mental disorders  Jack Nicholson in “One Flew over the Cuckoo’s Nest” Antipsychotic Drugs & Inpatients Psychological Therapies (Psychotherapy) Psychodynamic Therapies Humanistic Therapies Behavioral Therapies Cognitive Therapies Group-Therapy Approaches Psychodynamic Therapies I  The goal is to uncover and resolve conflicting thoughts, feelings, and intentions  Insight: an understanding of one’s own psychological processes     Free association Dream analysis: manifest vs. latent content Hypnosis Analysis of resistance  Resistance is the barriers to free association and treatment in general that the patient creates.  Catharsis: recovery into consciousness of repressed mental contents causes release of psychic energy and the melting away of associated symptoms Psychodynamic Therapies II  Therapeutic alliance     Patient-Therapist relationship Comfort level Nonjudgmental and empathetic listener Transference    Patients bring enduring interpersonal patterns into their relationship with their therapist Positive vs. negative Countertransference   Therapists may experience emotional responses to their patients Therapist must themselves undergo therapy in order to detect and handle these feelings Humanistic Therapies  Removing impediments to personal growth  Client-Centered Therapy – Carl Rogers  Warm and Caring Relationship  Empathy  Unconditional Positive Regard  Reflection  Gestalt Therapy – Fritz Perls  Empty chair technique   Imagine that the person to whom you wish to express your feelings is sitting in the empty chair Two chair technique  Place two sides of a dilemma in two different chairs and express each side while in that chair Behavioral Therapies I  Focus is on altering symptoms rather than exploring their meaning  Operant-Conditioning Techniques  Reward and Punishment    Biofeedback   Behavior modification Token economies To treat headaches or chronic pain (see next slide) Skills Training  Social skills – Assertiveness training  ADHD Biofeedback & Tension Headaches  Sensors on the head detect muscle activity  System converts signal to visual display  Patient watches the display, tries to reduce tension signal  Muscle tension reduced Behavioral Therapies II  Classical conditioning techniques are often used when there is a specific feared object (as in phobias) or desired object (as in addictions)  Flooding   Confronting a fearful stimulus without negative consequences will lead to extinction of the dysfunctional conditioned emotional response Systematic Desensitization  Associating positive feelings with a feared stimulus – Relaxation training, construction of fear hierarchy, and gradual exposure  Aversive Conditioning: associating negative feelings with a desirable, but unhealthy, object (see next slide) Aversion Therapy for Alcoholism  Alcohol is paired with a chemical that causes nausea and vomiting  Straightforward classical conditioning Cognitive Therapies I  Rational-Emotive Behavior Therapy  Albert Ellis  A form of cognitive therapy in which people are confronted with their irrational, maladaptive beliefs.  Common beliefs that are irrational and selfdefeating – I have to be liked by everyone – I have to be perfect at what I do – Everyone gets what they deserve  Therapeutic devices – Step out of character – “How to refuse to be ashamed of anything” – Try new behaviors to see that these behaviors won’t bring your life crashing down around you Cognitive Therapies II  A-B-C’s of Emotional Distress  Disorders often occur because of self- defeating beliefs  Activating Event - Beliefs - Consequences  Rational-emotive therapy helps people change these beliefs Cognitive Therapies III  Cognitive Therapy  Aaron Beck  A form of psychotherapy in which people are taught to think in more adaptive ways.  Address cognitive distortions  Catastrophizing: belief that was has happened was so awful or what will happen will be so terrible that you won’t be able to stand it  Overgeneralization: seeing a single negative event as a never-ending pattern of defeat  Address negative triad (world, self, future) in depression  World: interpret events unfavorably  Self: Does not like themselves  Future: Regard future pessimistically  Therapeutic devices Asking “What’s the evidence?” “Are these facts or interpretation?” “Is there another way to look at the situation?”  Triggering distress during therapy so that it can be interpreted  Keeping diaries or logs and doing reading assignments  Group Therapy Approaches  4 to 10 people meet with one or two therapists usually once a week for 2 hours  Successful group members can instill hope in newcomers  Discovering that others have similar problems can relieve shame and guilt  Group members talk about individual problems, but also gain insight from group processes in that people often interact with others in such a way that it is revealing Biological Therapies Drug Therapies (uses psychotropic medications) (also known as Psychopharmacology) Antianxiety Drugs  “Tranquilizers”  Can treat generalized anxiety  Barbituates  Work, but are highly addictive  Benzodiazepines  Increase activity of GABA, an inhibitory neurotransmitter  Examples (trade names in parentheses)     Diazepam (Valium) Chlordiazepoxide (Librium) Alprazolam (Xanax) Negative side effects     Drowsiness; dangerous when combined with alcohol After stopping, two-week rebound period of greater anxiety Can be psychologically and physically addictive Can cause memory loss  Buspirone (Trade name: BuSpar) Antidepressants  Tricyclic antidepressants  Block reuptake of serotonin and norepinephrine  Improvement of 40-50% over placebo  Imipramine (Trade name: Tofranil)  Placebo: Any medical intervention designed to work through the power of suggestion  A pill that does not contain any medically active ingredients can reduce symptoms by 20-40%  MAO (monoamine oxidase) inhibitors  MAO is an enzyme that breaks down serotonin   So, if you inhibit this enzyme, you will increase the amount of serotonin in the brain Effective when personality disorders are also present  Selective serotonin reuptake inhibitors (SSRI’s)  Fluoxetine (Trade name: Prozac) Antipsychotic Drugs  “Major tranquilizers”  Known as this because of sedating effects  Also known as “neuroleptics”  Reduce positive symptoms, like hallucinations and delusions   By inhibiting dopamine Do not do much for negative symptoms  Examples (trade name in parentheses)  Chlorpromazine (Thorazine)  Haloperidol (Haldol)  Clozapine (Clozaril)  Risperidone (Risperdal)  Side effects of thorazine: tardive dyskinesia  Involuntary twitching in tongue, face, neck, and jaw  Occurs in patients who have taken Thorazine for several years  Irreversible Other Medical Interventions  Electroconvulsive Therapy (ECT)  Electric-shock treatments that often relieve severe depression by triggering seizures in the brain.  Psychosurgery  The surgical removal of portions of the brain for the purpose of treating psychological disorders.  After, antipsychotic medications were introduced, psychosurgery was no longer a serious consideration  Lobotomy   Severing tissue in a cerebral lobe, typically the frontal lobe Produced severe side effects (see Phineas Gage) Treatment Effectiveness Psychotherapy Disorder-Treatment matches Usefulness of Psychotherapy  Two ways to evaluate the usefulness of psychotherapy  Effectiveness studies (this slide) vs. efficacy studies (next slide)  Effectiveness studies  Assessment of treatment outcomes under relatively less controlled conditions  1994 Consumer Reports Survey (N=2900)    2004 Consumer Reports Survey (N=3000)    Somewhat improved to much improved – 86% Fairly satisfied to highly satisfied – 89% 28% rise in the use of psychological medications Medication plus psychotherapy produces the best outcome, followed by psychotherapy alone, and then drug therapy alone Reasons to be critical of the use of effectiveness studies   Subjective measure No comparison to group that had problems but did not receive treatment Efficacy studies  Assessment of treatment outcomes under controlled conditions     Random assignment of subjects to conditions Therapists trained to adhere to manual Standardized length of treatment Summary of 475 efficacy studies (Smith et al., 1980)  The figure below shows that the average psychotherapy patient is better off than 80% of untreated patients Are some psychotherapies better?  On average, across all disorders, all therapies are equally effective (Sloane et al., 1977; Elkin et al., 1989)  However, for some disorders, certain types of therapy tend to be more successful than others  Two common, nonspecific factors at work in all types of psychotherapy   Supportive relationship with caring therapist gives patients reason for hope The opportunity for a patient to open up can have healing power  Pennebaker Anxiety Disorder & Treatment Match  For specific phobias  The sources of anxiety are better addressed with cognitivebehavioral therapy (CBT) than with medication   Systematic Desensitization Virtual treatments can reduce fear responses  For social phobia  SSRI’s help, but CBT is better  For panic disorder  Treatments often combine medication and CBT, but relapse is less with CBT  For obsessive-compulsive disorder (OCD)  For tic-related OCD, SSRI’s and dopamine receptor blockers  For non-tic-related OCD, oxytocin regulation  Exposure and response prevention therapy Exposure & Response Prevention  Another type of behavioral therapy  Woman with handwashing compulsion  Baseline Instruction Response prevention cycle  After a few cycles, the woman was washing less often and getting fewer urges to wash Hand washing Urges Depression & Treatment Match  Psychological medications  MAO-inhibitors, tricyclics, and SSRI’s provide relief to 6070% of depressed persons  Cognitive-behavioral therapy (CBT)  Just as effective psychological medications  Targets the automatic irrational thoughts that accompany depression  Medication plus CBT is most effective  Seasonal Affective Disorder  Responds to phototherapy  Exercise helps depression too  Electroconvulsive therapy (ECT)  The single most effective treatment for severe depression, and it saves lives, negative public views notwithstanding  Transcranial magnetic stimulation (TMS) Bipolar Disorder & Treatment Match  Lithium is “indispensable” for the treatment of bipolar disorder   Reduces bipolar mood swings Especially effective at calming mania  Less effective in reducing the severity of the depressive mood swings – For this reason, an antidepressant is often prescribed in addition to lithium  Takes awhile (3-4 weeks) to “kick in”   Side effects are unpleasant during this period Highly toxic  Only 20% of bipolar patients who maintain their medications experience relapse  But many patients discontinue medication, perhaps because of the “intoxicating pleasure” of manic states Schizophrenia & Treatment Match  Antipsychotic medications are indispensable for the treatment of schizophrenia  But significant sedative and motor side effects, resembling Parkinson’s disease, make treatment unpleasant for many patients  In addition, patients show little improvement in social skills  Psychosocial treatments  Improve functioning beyond drug treatments  Social skills training  Most schizophrenic patients improve as they get older Professionals Involved in Therapy  Clinical Psychologists  Psychiatrists  Psychiatric (or clinical) social worker  Psychiatric nurse  Counseling Psychologists  Psychoanalysts  Others offering therapy (paraprofessionals)  Crisis intervention  Pastoral Counselors  Community outreach Where People Turn for Help Orientations of Psychotherapists Can Personality Disorders Be Treated?  Dialectical Behavior Therapy Is Most Successful for Borderline Personality Disorder  Antisocial Personality Disorder Is Difficult to Treat The Use of Medication to Treat Adolescent Depression Is Controversial  Fewer than 30 percent of children who have mental health problems receive any type of treatment  Twice as many of those taking SSRIs reported having suicidal thoughts (4 percent) as those taking a placebo (2 percent)  None of the children or adolescents committed suicide  The FDA voted in 2004 to require manufacturers to add to their product labels a warning that antidepressants increase the risk of suicidal thinking and behavior in depressed children and adolescents The Use of Medication to Treat Adolescent Depression Is Controversial  The previous slide displayed the results of the TADS study    All treatment groups experienced a reduction in thoughts of suicide compared with the baseline However, participants in the Prozac group were twice as likely to have serious suicidal thoughts or intentions compared with those undergoing other treatments Although prescribing drugs without CBT might be cost effective, it may not be in the best interests of depressed children Children with ADHD Can Benefit from a Variety of Approaches  Methylphenidate (ritalin) targets under active brains and reduces negative behaviors (see Fig. 14.29 and Fig. 15.23)  Side effects and lack of long-term efficacy limit the utility of ritalin  Behavioral Treatments, though time-consuming, augment medication and help social skills, academics, and family relationships Autistic Children Benefit from a Structured Treatment Approach  Generalization of skills must be taught explicitly  Applied Behavior Analysis (ABA) is time intensive but raises IQ points by 20 onaverage  The long-term prognosis for autism is poor
