Mixed Methods Analysis of Implementation of Interpersonal Psychotherapy (IPT) for Major Depressive Disorder in Prisons in a Hybrid Type I Randomized Trial.

This article describes a mixed methods evaluation of implementation of interpersonal psychotherapy (IPT) in the first fully-powered trial of any treatment for major depressive disorder in an incarcerated population. Assessments in this Hybrid Type I trial included surveys of prison providers and administrators (n = 71), measures of feasibility and acceptability to prison patients (n = 90), and a planned document review (n = 460) to assess potential determinants of implementation. Quantitative and qualitative results indicated that IPT was a good fit for prisoners, and that prisoners and providers were enthusiastic about IPT.
