Motivational Enhancement Therapy for Increasing Antidepressant Medication Adherence and Decreasing Clinical Depression Among Adult Latinos
Case Studies Within Psychotherapy Trials: Integrating Qualitative and Quantitative Methods presents a specific, mixed-methods approach, called the “Cases Within Trials” (CWT) model, to psychotherapy research, combining the results from a randomized clinical trial (RCT), from case studies drawn from the RCT, and a synthesis of the two types of knowledge. Chapter 6 of the book applies this model to a study of the application of a three-session, individual, “motivational interviewing” therapy—specifically labeled “motivational enhancement therapy for antidepressants” (META). META was employed for treating disadvantaged, predominantly Spanish-speaking Latinos with depression. Finding META plus routine individual psychiatric therapy based in a community mental health center (CMHC) to be statistically and substantially superior to the CMHC-therapy-only condition, the authors then analyze and compare the positive-outcome case of Lupe, the mixed-outcome case of Ana, and the negative-outcome case of Maria, all drawn from the META condition.
