A New Community-Based Model for Training in Evidence-Based Psychotherapy Practice

The Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) for serious mental illness in community mental health part 2: Study protocol for a hybrid type 2 effectiveness-implementation cluster- randomized trial using train-the-trainer

Background

Train-the-trainer (TTT) is a promising method for implementing evidence-based psychological treatments (EBPTs) in community mental health centers (CMHCs). In TTT, expert trainers train locally embedded individuals (i.e., Generation 1 providers) to deliver an EBPT, who then train others (i.e., Generation 2 providers). The present study will evaluate implementation and effectiveness outcomes of an EBPT for sleep and circadian dysfunction-the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C)-delivered to CMHC patients with serious mental illness by Generation 2 providers (i.e., trained and supervised within CMHCs via TTT). Specifically, we will investigate whether adapting TranS-C to fit CMHC contexts improves Generation 2 (a) patient outcomes (b) providers' perceptions of fit.

Methods

TTT will be implemented in nine CMHCs in California, United States (N= 60 providers; N= 130 patients) via facilitation. CMHCs are cluster-randomized by county to Adapted TranS-C or Standard TranS-C. Within each CMHC, patients are randomized to immediate TranS-C or usual care followed by delayed treatment with TranS-C (UC-DT). Aim 1 will assess the effectiveness of TranS-C (combined Adapted and Standard), compared to UC-DT, on improvements in sleep and circadian problems, functional impairment, and psychiatric symptoms for Generation 2 patients. Aim 2 will evaluate whether Adapted TranS-C is superior to Standard TranS-C with respect to Generation 2 providers' perceptions of fit. Aim 3 will evaluate whether Generation 2 providers' perceived fit mediates the relation between TranS-C treatment condition and patient outcomes. Exploratory analyses will: (1) evaluate whether the effectiveness of TranS-C for patient outcomes is moderated by generation, (2) compare Adapted and Standard TranS-C on patient perceptions of credibility/improvement and PhenX Toolkit outcomes (e.g., substance use, suicidality); and (3) evaluate other possible moderators.

Discussion

This trial has potential to inform the process of (a) embedding local trainers and supervisors to expand delivery of a promising transdiagnostic treatment for sleep and circadian dysfunction, (b) adding to the growing body of TTT literature by evaluating TTT outcomes with a novel treatment and population, and (c) advancing our understanding of providers' perceptions of EBPT 'fit' across TTT generations.

Transcultural adaptation of interpersonal psychotherapy in Asia

Interpersonal Psychotherapy (IPT) has been utilized with great efficacy and effectiveness across many cultural settings. The attachment theory upon which IPT rests provides a strong foundation for IPT cross-culturally: regardless of their geographic location, people are people and their relationships are important. Though the structure of families and individual social roles varies greatly across cultures, people relate to one another. They become distressed when they have problems with interpersonal conflict, change, and loss of relationships. In this article, we review the basics of IPT and then describe the ways in which cultural adaptations can be made for people in Asia. Both are large tasks-to summarize IPT concisely while providing sufficient information is difficult; describing cultural adaptions for people in geographical areas from Russia to China to India to Southeast and Central Asia and all of the ethnic and language groups that area includes is nigh well impossible within a review article. Thus we have restricted our cultural overview to areas in which we have experience clinically and in which we have been active with IPT training, supervision, and implementation. All of the work we describe, however, elaborate on the principles of cultural adaptations which can be used to implement IPT in other local contexts.
