Effective Implementation of Interpersonal Psychotherapy

Pragmatic Strategies for Assessing and Enhancing High Fidelity Delivery of Interpersonal Psychotherapy (IPT) in Community Practice

The study is designed to observe the impact of improved measures of the fidelity on the community delivery of Interpersonal Psychotherapy.
