Psychotherapy credibility ratings: patient predictors of credibility and the relation of credibility to therapy outcome.

OBJECTIVE: The current investigation examined the relation between credibility ratings for adult psychotherapies and a variety of patient factors as well as the relation between credibility ratings and subsequent symptom change. METHOD: A pooled study database that included studies evaluating the efficacy of cognitive and psychodynamic therapies for a variety of disorders was used. For all studies, a three-item credibility scale was administered at session 2. Patient variables at baseline were used to predict early treatment credibility. RESULTS: Early symptom improvement, age, education, and expectation of improvement were all significantly predictive of credibility scores at session 2. In one combined multiple regression model controlling for treatment, study, and early symptom change, age, education, and expectation of improvement remained significantly predictive of credibility scores. Credibility was predictive of subsequent symptom change even when controlling for age, education, expectation of improvement, and early symptom improvement. CONCLUSIONS: These findings suggest that age and education, in addition to expectations of improvement and the amount of early symptom improvement, may influence the patient's perceptions of the credibility of a treatment rationale early in the treatment process and that credibility ratings predict subsequent symptom change.

Supportive-expressive dynamic psychotherapy in the community mental health system: a pilot effectiveness trial for the treatment of depression.

The goal of the current article is to present the results of a randomized pilot investigation of a brief dynamic psychotherapy compared with treatment-as-usual (TAU) in the treatment of moderate-to-severe depression in the community mental health system. Forty patients seeking services for moderate-to-severe depression in the community mental health system were randomized to 12 weeks of psychotherapy, with either a community therapist trained in brief dynamic psychotherapy or a TAU therapist. Results indicated that blind judges could discriminate the dynamic sessions from the TAU sessions on adherence to dynamic interventions. The results indicate moderate-to-large effect sizes in favor of the dynamic psychotherapy over the TAU therapy in the treatment of depression. The Behavior and Symptom Identification Scale-24 showed that 50% of patients treated with dynamic therapy moved into a normative range compared with only 29% of patients treated with TAU.
