Psych 100 Lesson 17 Treatment (2)
- Behavior Therapies - involve the application of learning principles to direct efforts to change clients' maladaptive behaviors
- Behaviorist perspective
- No insights, no defense mechanisms, unconscious conflicts, childhood trauma, no parents
- Problems arise from bad behaviors learned behaviors
- Fix is to learn good behaviors
- "psychological" problems all disappear with the bad behaviors
- Usually apply the classical conditioning model (Pavlov)
- Conditioning results from pairing of CS with UCS so that CS now elicts a UCR
- Counterconditioning pairs CS with UCS without UCR, connection extinguishes
- Sytematic desensitization -Wolpe 58- behavior therapy used to reduce phobic clients' anxiety responses through counterconditioning
- Therapist builds anxiety hierarchy, what is bothering the patient
- Train deep muscle relaxation, relaxed state is incompatible with anxiety
- Patient works through hierarchy by imagining each source of anxiety
- Another approach is gradual physical approximation: fear of flying
- Recent variation, virtual reality: treatment for post traumatic stress disorder
- Aversion Therapy - a behavior therapy in which an aversive stimulus is paired with a stimulis that elicits an undesirable response.
- Pairs aversive UCS with target CS of bad behavior so CS elicits aversive UCR
- Bingeing and sickness, my job as a bartender
- Emetic drug (Anabuse) makes alcoholic sick when he/she drinks alcohol
- Basis for therapy in "Clockwork Orange"
- Social Skills Training - a behavior therapy designed to improve interpersonal skills emphasized modeling, behavioral rehearsal, and shaping.
- Modeling, emulating others to acquire correct behavior "Desperately Seeking Susan"
- Behavioral rehearsal, role playing to correct inappropriate behaviors
- Shaping, multiple approximations to the desired behavior
- Can be used in schizophrenic and autistic, when positive and negative stimuli identifiable
- Biofeedback - monitor body states (heartrate, GSR, EMG, etc) and feedback results so person can achieve relaxation
- Does not alter person, can be done with or without supervision (not considered biological)
- Successfully used in treating anxiety, tension, migranes
- Evaluating behavior therapies
- Measure objective behavior progress, not subjective feelings of wellness
- Controversial, prisons have had behavioral programs halted because of prisoner rights
- Effectiveness varies greatly with therapist skills
- Biomedical Therapies - physiological interventions intended to reduce symptoms associated with psychological disorders
- Background
- Includes drugs, ECT, surgery
- Widely employed today, often first approach
- Psychopharmacotherapy
- Delay and Deniker 52 first use chlorpromazine on schizophrenic patients, first drug therapy
- Antianxiety drug therapy- relieve tension, apprehension, nervousness
- Benzodiazepine tranquilizers
- Include diazepam (valium) and alprazolam (Xanax)
- Chemically prevent tension or anxiety
- Side effects of drowsiness, depression, anxiety and confusion
- Can cause withdrawal symptoms
- Newer drugs buspirone (Buspar) have fewer side effects
- Meant to be used as short term facilitators of therapy, abuse problems
- Antipsychotic drug therapy- reduce psychotic symptoms including hyeractivity, confusion, hallucinations, and delusions
- Chlorpromazine (Thorazine), thioridazine (Mellaril), haloperidol (Haldol)
- Most patients respond to drugs, but with varying degrees of success
- Side effect of drowsiness, constipation, cotton mouth, tremmors, rigidity, impaired motor coordination drive patients to stop drug, 2/3 relapse
- Tardive dyskinesia involuntary writhing, tics in mouth face, tongue, hands, feet
- New drugs atypical antipsychotics (clozapine, olanzapine,quetiapine) reduce but do not eliminate side effects
- Antidepressant drug therapy - elevate mood and reduce depressive symptoms
- Early drugs include tricyclics (Elavil) and MAO inhibitors (Nardil), have serious side effects
- New drugs include selective serotonin reuptake inhibitors SSRIs like fleoxetine (Prozac), paroxetine (Paxil), sertraline (Zoloft) with fewer side effects
- Side effects include sexual and withdrawal symptoms
- Antibipolar drug therapy
- Metal Lithium dampens mood swings of bipolar mood disorders
- Requires careful monitoring, too little has no effect, too much toxic, affects kidneys and thyroid
- Evaluating drug therapies
- Drugs offer temporary relief, not long term solutions
- Side effects may be nearly as bad as mental illness
- Over prescription and abuse
- Electroconvulsive Therapy (ECT) biomedical treatment in which electric shock is used to produce a cortical seizure accompanied by convulsions
- Background
- Seizures & schizophrenia, von Meduna 30's, electrical Cerletti and Bini, 38
- Method
- light anesthetic, protective countermeasures
- Uni- or Bi-lateral application of current
- Mechanisms of effect unknown
- Some data supports use in severe mood disorders
- Side effects include short term cognitive deficiency, memory loss
- Bill's theory, patients get better for fear they will get brains fried!
- Other treatment issues
- Managed care and restricting insurance for psychological problems
- Evaluation methods lacking
- Blending multiple approaches, drugs with others may be most effective
- Eclecticism runs contrary to the "school" approach to therapy
- Multicultural issues in an increasingly pluralistic society
- Cultural barriers
- Language barriers
- Access barriers
- Institutional barriers
- Institutional treatment
- History of poor care
- Deinstitutionalization - from inpatient to community-based facilities offering out-patient
- Mental Illness, revolving door and homelessness
- Perspective
- Mental health care in America is only fair among industrialized nations
- HMOs have exacerbated the problem
