There are significant barriers to widespread implementation and sustainment of evidence-based psychological treatments (EBPTs) in community mental health centers (CMHCs), including insufficient time and funding, shortage of trainers and consultants, and staff turnover. The investigators propose to evaluate one possible solution, the train-the-trainer (TTT) approach, in the context of a transdiagnostic EBPT for sleep and circadian dysfunction-the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C)- for serious mental illness (SMI) in CMHCs. This entry describes the Train-the-Trainer Phase, the second of a three-phase hybrid type 2 effectiveness-implementation trial conducted to test TranS-C in CMHCs.

TTT is a training structure with multiple levels, called "Generations." First, external expert trainers train an initial cohort of providers in a specific EBPT ("Generation 1 providers"). Next, Generation 1 providers are offered additional training in how to train others in the EBPT and become "local trainers." These local trainers then train the next cohort of providers within their organization ("Generation 2 providers").

The Train-the-Trainer Phase builds upon the first phase, the Implementation Phase (NCT04154631), in which implementation and effectiveness outcomes of two versions of TranS-C, Standard and Adapted are compared, with CMHC providers, who are trained by treatment experts. Adapted TranS-C is a version of TranS-C designed to improve 'fit' with the CMHC context. In the Train-the-Trainer Phase, the aim is to test implementation and effectiveness outcomes of Standard and Adapted TranS-C with CMHC providers who are trained and supervised within CMHCs (i.e., Generation 2 of TTT).

In the Implementation Phase, 10 CMHC clinic sites were cluster randomized to either Standard or Adapted TranS-C. Nine CMHCs continued participation into the Train-the-Trainer Phase. Within each CMHC site, patients are randomized to immediate TranS-C or to Usual Care followed by Delayed Treatment (UC-DT). Generation 2 patients (n=130) will be assessed pre, mid and post-treatment and at 6 month follow-up. UC Berkeley will coordinate the research, facilitate implementation, collect data, etc. Generation 2 providers (n=60), trained by local trainers within an established network of CMHCs, will implement TranS-C and will be assessed at pre and post-treatment. SA1 is to confirm that both Standard vs. Adapted TranS-C, compared to UC-DT, improve sleep and circadian functioning and reduce functional impairment and disorder-focused psychiatric symptoms for Generation 2 patients. SA2 is to evaluate the fit, to the CMHC context, of Standard vs. Adapted TranS-C via Generation 2 provider ratings of acceptability, appropriateness and feasibility. SA3 will examine if better fit, operationalized via Generation 2 provider ratings of acceptability, mediates the relationship between treatment condition and Generation 2 patient outcome. This research will determine if (1) sleep and circadian problems can be effectively addressed in SMI by CMHC providers trained and supervised within CMHCs via the train-the-trainer approach, (2) test two variations of TranS-C that each have unique advantages and focus on community providers and typical community patients.
