Implementing and Sustaining a Sleep Treatment to Improve Community Mental Health Part 3: Sustainment

Research on the sustainment of implemented evidence-based psychological treatments in routine practice settings, such as community mental health centers, is limited. The goal of this study is to test sustainment predictors, mechanisms, and outcomes of the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) in community mental health centers after implementation efforts have ended. CMHC providers have been trained to deliver a "Standard" or "Adapted" version of TranS-C. Researchers will compare these two groups to evaluate differences--and possible mechanisms--with respect to sustainment outcomes.

More research on the sustainment of implemented evidence-based treatments in routine practice settings, such as community mental health centers (CMHCs), is needed. This study is the third and final phase-i.e., the Sustainment Phase-of a cluster-randomized controlled trial and focuses on CMHC providers' sustainment of the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C). The Sustainment Phase seeks to build on the two earlier phases of the trial-the Implementation Phase (NCT04154631) and Train-the-Trainer Phase (NCT05805657)-during which TranS-C was adapted to fit the CMHC context, and ten CMHCs were cluster-randomized to implement Standard TranS-C or Adapted TranS-C via facilitation and train-the-trainer. Data collection for the Sustainment Phase will commence at least three months after implementation efforts in partnering CMHCs have ended. Note that in this study, sustainment is operationalized per Shediac-Rizkallah and Bone's framework (1998) and defined as continued (a) activities, (b) benefits, and (c) capacity of an intervention after implementation efforts have ended.

Aim 1: Report the sustainment outcomes of TranS-C after implementation support has ended.

Aim 2: Evaluate whether manipulating fit to context predicts sustainment outcomes. It is hypothesized that providers in Adapted TranS-C will report better sustainment outcomes (i.e., activities, benefits, and capacity) relative to Standard TranS-C.

Aim 3: Test whether provider perceptions of fit-operationalized as acceptability, appropriateness, and feasibility-mediate the relation between treatment condition (Standard versus Adapted TranS-C) and sustainment outcomes. It is hypothesized that Adapted TranS-C, compared to Standard TranS-C, will predict better sustainment outcomes (i.e., activities, benefits, and capacity) indirectly through better provider perceptions of fit.
