| Social Problems of Providing Care for the Mentall Ill | |
A. History of treatment:1. Middle Ages (attributed to being possessed by the devil or supernatural powers): torture, hanging, burnt at stake, "ships of fools." 2.
18th Century (attributed to degeneracy or unworthiness): chained in
prisons or dark, damp hospitals. B. Reform"moral-treatment movement," 19th Century: 1. Philippe Pinel, Paris: unchained, sunny, airy rooms, exercise. 2. Dorothea Dix, U.S.: publicized appalling conditions. 3. State-supported asylums built.
1. 1940's: overcrowded, understaffed, poor treatment. 2. 1950's: deinstitutionalization inspired by effective drugs and optimism. 3. 1960's: community-based mental health centers. 4. Current: debatable improvement in treatment.
1. Little contact with psychiatrists. 2. Dehumanizing interactions. 3. Physical and verbal abuse.
1. Standard hospital treatment. 2. Milieu therapy: frequent interaction, respect, high expectations, democratic decision, reduction/elimination of antipsychotic drugs. 3. Social-learning therapy: milieu conditions plus social skills training. 4. 97% of social-learning group were able to live in the community.
1. Mental hospitals: public, private. 2. General hospitals. 3. Nursing homes. 4. Halfway houses. 5. Private offices (72% of patients). 6. Community mental health centers (16% of patients).
1. Psychiatrist. 2. Clinical psychologist. 3. Counseling psychologist. 4. Counselors. 5. Psychiatric social workers. 6. Psychiatric nurses. 7. Other: religious organizations, self-help groups.
1. Definition of mental disorder (see chp 16). 2. Most people with mental disorders never seek or obtain treatment. 3. Demographics of individuals with diagnosable disorders who seek help: a. Sex: 25% women; 20% men. b. Education: 43% college graduates; 11% less then high school. c. Race: 27% white; 17% non-white. d. Income level: 37% <$35,000; 20% <$10,000. e. Higher income >> less the incidence of mental disorder and seeing a professional. 4. Other reasons for seeking mental health treatment: a.
Life problems, marital problems. d. Substance abuse or dependence. |

| Methods of clinical assessment | |
|
A.
Assessment: Assessments are used for: 1. Diagnosis. 2. Understand the individual, life circumstances, thoughts and behaviors. 3. Monitor changes for determining treatment modification or discontinuation. 4. Theoretical orientations that guide assessment:
1. Assessment interview: (most common procedure) dialogue to learn about client.
2. Objective questionnaire: self report of feelings, thoughts and behaviors. (Example: Beck Depression Inventory.)
1. Purpose: to provide an objective means of diagnosing mental disorders, uncontaminated by the biases of a clinician. 2. Criticism: cultural biases. 3. MMPI-2 (1980s): revised to increase validity.
1. Free association: free mind constraints of logic and say whatever comes to mind in response to a word or other stimuli. 2. Rorschach test: symmetrical inkblots. 3. Thematic apperception test (TAT): pictures of ambiguous scenes.
1. Self-monitoring: client records his/her own behaviors.
F. Brain damage and neuropsychological functioning: 1. Electroencephalogram (EEG): measures patterns of electric activity. 2. Computerized axial tomography (CAT) scan: multiple x-rays from various angles. 3. Magnetic resonance imaging (MRI) scan: strong magnetic field constructs pictures based on electromagnetic radiation given off by molecules in the brain. 4. Positron emission tomography (PET) scan: images of patterns of blood flow and oxygen use. 5. Halstead-Reitan battery: identification of functional deficits related to brain damage. |
|
| Biological approaches to treatment: directly altering bodily processes | |
A. Historical treatments:1. Trephination: drilling holes in the brain to allow evils spirits to escape. 2. Bloodletting.
1. Phenothiazines: decreases dopamine activity.
2. Clozapine: blocks less dopamine and blocks more serotonin.
1. Tricyclics: increases availability of serotonin and norepinephrine by blocking their reuptake in the synapse. (Examples: imipramine, amitriptyline.)
2. Selective serotonin reuptake inhibitors (SSRIs): increases availability of serotonin by blocking its reuptake only. (Examples: Prozac.)
1. Mineral element that stabilizes monoamines. 2. Controls both mania and depression. 3. Serious side effects at high doses. E. Antianxiety drugs: for treatment of generalized anxiety. 1. Tranquilizers. (Example: phenobarbital.)
2. Benzodiazepines: augments the inhibitory transmitter gammaaminobutyric acid (GABA) which decreases neuron excitability. (Examples: Librium and Valium.)
F. Electroconvulsive shock therapy (ECT): electric current passed through the skull causing a brain seizure. 1. Used for severe depression that has not responded to conventional therapies. 2. Criticism: possibility of permanent brain damage. 3. Problem: may cause temporary memory loss. 4. Bilateral ECT: electric current passes through both hemispheres; unilateral ECT: current passes through only one hemisphere (usually the right).
1. Frontal lobotomy (1930s-50s, Egas Moniz): the front portions or the brains frontal lobes are surgically separated from the rest of the brain.
2. Cingulotomy: destruction of small areas of the brain by applying radio-frequency current through wire electrodes.
3. Procedures are irreversible; appropriate for disorders persisting for 10 or more years, when conventional treatments have failed and patient is suicidal. |

| Major Forms of Psychotherapy | |
Fformal, theory-based systematic treatment for mental problems or disorders that use psychological means and conducted by a trained therapist.A. Psychodynamic therapies: Therapy based on the premise that psychological problems are manifestations of inner mental conflicts and that conscious awareness of conflicts is key to recovery. (Psychoanalysis: term coined by Freud.) 1. Wishes and memories (especially sex and aggression) are unconscious. 2. Repression: defense mechanism to keep wishes unconscious. 3. Neuroses: emotional disorders arise from memories or wishes becoming conscious and causing emotional breakdown.
4. Free association (defined above). 5. Dream interpretation: purest form of free association.
6. Mistakes (i.e., "slip of the tongue", "Freudian slip"): expressions of unconscious wishes. 7. Resistance: refusal to talk about a topic, forgetting or arguing as defenses against unconscious memories becoming conscious. 8. Transference: patients unconscious feelings about a person are experienced as conscious feelings about the therapist. 9: Cure: Memories and wishes become conscious and experienced directly or modified. Patient no longer represses freeing psychic energy for other pursuits.
B. Modern psychodynamic therapies: 1. Similar to Freuds psychoanalysis. 2. Differences:
3. Non-Freudian psychodynamic therapies (Adler, Jung, Horney): emphasizes other conflicts (not just sex and aggression).
1. Rogers client-centered therapy: focuses clients positive attributes and how he/she can use them to identify problems and make improvements.
i. Empathy: gain clients perspective. ii. Unconditional positive regard: client is worthy and capable. iii. Genuineness: empathy and positive regard cannot be fake.
1. Therapists role: directive, teaching. 2. Problem: people are disturbed by maladaptive thoughts that produce anxiety or depression. 3. Therapy goals: identify maladaptive thought patterns; replace with adaptive thoughts. 4. Elliss rational-emotive therapy (RET) (1955): negative emotions arise form peoples irrational interpretations of their experiences, not objective experiences.
i. A = activating event in the environment. ii. B = belief triggered when the event occurs. iii. C = emotional consequence of that belief. 5. Becks cognitive therapy: negative self-concept due to routine distortion of experience.
1. History: based on laboratory work of Pavlov, Watson and Skinner. 2. Cognitive-behavior therapy: focuses on mental process as mediators between stimuli and responses.
3. Exposure treatments: fear paired with harmless contexts until it is habituated (for unconditioned fears) or extinguished (for conditioned fears).
4. Aversion treatments: reduction or elimination of a harmful habit by applying aversive stimuli immediately after it occurs. (Example: antabuse.) a. Criticism: learned aversions do not generalize beyond the condition in which they are applied. 5. Other techniques:
1. Group therapies: one therapist meeting with more than one client at once.
2. Couple/family therapy: one therapist meets with a married or cohabiting couple, or a whole family.

| Evaluating psychotherapies | |
|
A. Controlled experiments. (Example: Philadelphia experiment, 1975.) B. Therapy outcome experiments conclusions: 1. Psychotherapy produces improvement more than no treatment. 2. No single type of therapy is generally superior. 3. Some types of therapy work best with specific kinds of disorders or problems.
4. The therapist matters.
C. Non-specific factors in therapy outcome: factors unrelated to the specific therapy principles. 1. Support: acceptance, empathy, encouragement, guidance.
2. Hope: faith in the therapy process.
