3. Hans Eysenck (1952) – published a paper showing that clients in therapy were worse off than untreated individuals  44% of clients in psychoanalytic treatment improved  64% of clients in eclectic treatment improved  72% of clients not in therapy improved  Several problems with the study invalidated results – but led to push for additional research on effectiveness Does Psychotherapy Work?

4.  Meta-analysis: quantitatively combining several studies to measure the effect of a variable  Effect size: Numeric value that indicates size between group differences (d=.5 means ½ SD between group difference)  Can also be presented as an r statistic when correlational studies are used  First meta-analysis (1977): psychotherapy has an effect of d=.68 Does Psychotherapy Work?

5.  Subsequent research (e.g., Smith, Glass, & Miller, 1980) indicates d=.85.  That is, the average person in therapy is better off than 80% of people without therapy  Subsequent research validated these findings Criticisms of meta-analysis:  “garbage-in, garbage-out”  “apples and oranges” Does Psychotherapy Work?

6. Clinical Practice Guidelines:  Rules and guides for particular problems. Clinical Psychology has not been quick to adopt these structures Empirically Supported Treatments (ESTs):  Specific criteria must be met for a treatment to be an EST to be recommended for use.  Section on Clinical Psychology of the Canadian Psychological Association (CPA) struck a task force in 1996 to examine ESTs  Several criticisms of ESTs emerged – see Exhibit 12.2 Evidence-Based Treatments: Initiatives and Controversies

7.  Statistically significant differences  Differences not due to chance  Clinically significant differences  Improved quality of life, cure, recovery  Different types of clinical trials:  Type 1: High quality Randomized Controlled Trials (RCTs)  Type 2: Imperfect RCTs  Type 3: Open trials without a control condition Evidence-Based Treatments: Initiatives and Controversies

8. Different types of clinical trials (cont.):  Type 4: Quantitative meta-analyses  Type 5: Qualitative literature reviews  Type 6: Case studies or professional consensus statements not based on research  The EMDR debate and recent findings – concludes that eye movement does not add to treatment of trauma Evidence-Based Treatments: Initiatives and Controversies

14.  Current research indicates that efficacy trials can be translated into real-word settings  Effectiveness studies show similar results  Benchmarking strategies: using efficacy trials as a mark for whether the translation of a treatment is working in the real world Translating Efficacy to Effectiveness
