Psychotherapy Research Flashcards
General Outcome Studies
Eysenck
Smith, Glass, Miller
**Eysenck: **
- summarized 24 outcome studies
- effects of psychotherapy are small or nonexistent
- any positive effects may reflect nothing more than spontaneous remission.
- SMITH et al. challenged results using META-Analysis
- the meta analysis combined statistics from studies to calculate an effect size for common metric
- subtract mean from control from mean of treatment group and divide difference by the SD of the control group
- number indicates difference between average patients in the treatment and control group in terms of SD units.
Smith, Glass and Miller:
- used meta-analysis to combine 475 outcome studies and got an effect size of .85
- average therapy client is better than 80% of those who need therapy but remain untreated.
- psychological treatments are generally efficacious in practical and statistical terms.!
- no one type of therapy is consistently superior to any other type across disorders
- CBT is better for panic, phobias, and compulsions.
- shared therapy factors like catharsis, positive relatioinship, bx regulations and cognitive learning and mastery seen as key, not certain technique…but what they all share!
Effects of Treatment Length
Dose-Dependent Effect: Howard et al. found that 75% patients showed meansurable improement at 26 session but only 85% with 52 sessions (double the length showed only 10% increase).
Phase Model:
-
Remoralization:
- client’s feelings of h_opelessness & desperation_ respond quickly to therapy, all in a few sessions (the initial rush).
- evaluate well-being
-
Remediation:
- focus is on the symptoms that brought the client to therapy.
- Symptom relief in about 16 session.
- evaluate/id symptoms
-
Rehabilitation: unlearning troublesome, maladaptive, habitual bx and creating new ways to deal with aspects of life.
- Sesssion # dependent on type and severity of problem.
- evaluate functioning
Efficacy vs Effectiveness
Efficacy (clinical trials):
- most useful for establishing whether or not a treatment has an effect.
- However, Seligman argues: efficacy study omits too many crucial elements of what is actually done in the field
Effectiveness (correlational or quasi-experimental)
- strict experimental control needed by efficacy studies limits the generalizability of their results, thus effectiveness research is more indicated/valid.
- best for assessing clinical utility, or determining a treatment’s generalizability, feasibility, and cost-effectiveness.
Research on Psychotherapy with Members of Diverse Populations
Sue et al.: GAS scores post therapy showed the best improvement for Hispanics, Anglo, Asian, and AA (in order).
Utilization of MHS:
- Blacks receive a disproportional share of MHS in the ER or psychiatric inpatient
- Asians are mostly underrepresented in out and in patient settings.
- Black larger treatment for alcohol, and more Whites for depression compared to blacks/hispanics
Premature Termination:
- compared to whites, all other cultures/ethnic groups terminate more after 1 session (50% vs. 30%).
- But for community clinics it was: blacks, white/hispanic, and asians (lowest d/o).
Effects of Therapist-Client Matching
- mixed results if any effect correlating if ethnic matching has any benefit to retention of service.
- factors like client’s ethnic identity, level of acculturation, gender, and trust of whites may be issue.
- Those who benefit from client-therapist matching in terms of ethnicity, culture, or race may reduce pre-mature termination for Asians, Hispanics and Whites, but not for Blacks (so stubborn).
Interventions with Older Adults
Prevalence of MH problems among older adults:
anxiety, severe cognitive impairment, and depression (in order).
- Very heterogenious group compared to others.
- Respond to the same degree to psychotherapies as younger adults, but more slowly.
-
Best interventions (in order):
- Behavioral and environmental interventions with older folks with dementia
- memory and cognitive retraining is ‘probably efficacious’ with dementia
- cognitive, behavioral and brief therapies also ‘probably efficacious’ with depression.
- Best interventions for old farts are tailored to their specific needs and circumstances (slower processing, low memory, increase emotional complexity).
Interventions for Victims of Spousal/Partner Abuse
- Great abuse of woman (20% vs 7%)
- greater abuse of younger women, heterosexual, American Indian/Alaska Native (followed by Blacks) and in families with very low SES.
- Low SES was the best single predictor of cessation of battering (lower SES most likely to continue beating)
Intervention:
- Goals of intervention emphasize self-determination, ensure safety, increasing self-esteem, empowerment and control.
- assessments that are valid and meet their needs.
- cultrual and contextual factors assessed.
- clinicians must continually self-monitor their own feelings, attitudes and bx. Be in tune with vicarious trauma and changes in perceptions (safety).
Victim and Perpetrator conjoint therapy?!
- Expressive Abuse ( mutual emotion followed by remorse) can be conjoint.
- Instrumental Abuse (impulsive, goal seeking, unilateral, no remorse) therapy done separately in separate locations.
Factors to Stay in Abusive Relationship
- Woman’s commitment to the relationship, emotional level of attachment, to save it, or been in it for many years.
- economic dependence, belief that batterer will change, fear of retaliation if she leaves.
Other Issues in Psychotherapy Practice and Research
Treatment Manuals
- empirically evaluated, standardized treatments.
- can be oversimplified and lead to misuse of therapy techniques.
- but may also benefit from set clinical decision making guidelines, and avoid many pitfalls of individual clinical judgment.
Placebo Effect
- means: providing participants with the nonspecific (common) factors of psychotherapy such as attenbtion and support.
- research shows that placebo conditions have a substantial impact (.67 compared to no trtment, but .48 compared to trtment).
- Diagnostic Overshadowing: tendency of health professionals to attribute all bx, soical, and emotional problems to MR people (everything is about the problem).
- applies to other diagnoses and situations, and not related to professional’s orientation, expertise or experience.
- Vocational Overshadowing: therapist overlooks vocational problems as they co-exist with personal problems (overshadowed).
_Alloplastic vs. Autoplastic Interventions: _
- Alloplastic Intervention: goal is to make changes in the environment so that it better accommodates the person.
- Autoplastic Intervention: goal is the change the individual so he is better able to function effectively w/in his environment.
Therapist Distress
- Survey found that 74% of therapists had personal distress in last 3 years, w/ 36% saying decresed quality of work and 4% saying led to inadequate trtment.
- suicidal statemtns are the most stressful type of client bx.
- lack of therapeutic success is most stressful aspect of their work
- confidentiality issues are most frequently ethical/legal dilemma.
Psychiatric Hospitalization
- mental illness higher with females in each age group
- admission to hospital is higher for men
- but more women in outpatient services!
- men may be more externalizers and at risk to harm, compared to anxious/depressed females.
- commitment criteria changed from psychopathology to perceived dangerousness.!
- Admission to hospital data
- highest for never married, middle for married/divorced, and low for widowed.
- whites highest frequency, but proportionally, minorities are overrepresented!
- whites represent 70% of admissions to both inpatient and outpatient services.
- largest admission is for 25-44 yo (both sexes).
- Schizophrenia most common admission for 18-44 yo,
- but 65+ yo an organic disorder is most common followed by affective dx.
