An obstacle to the roll-out of evidence-based psychological treatments (EBPTs) for severe mental illness (SMI) is that the context for the implementation typically differs from the original testing context causing a lack of "fit" between the setting and the EBPT. The investigators propose to evaluate if adapting a specific treatment to improve the contextual fit improves outcomes in a setting that typifies this challenge-community mental health centers (CMHCs).
Following the Experimental Therapeutics Approach, the target is sleep and circadian dysfunction. In SMI, sleep and circadian dysfunction undermines affect regulation, cognitive function and physical health, predicts the onset and worsening of symptoms and is often chronic even with evidence-based SMI treatment. Prior treatment studies have been disorder-focused-they have treated a specific sleep problem (e.g., insomnia) in a specific diagnostic group (e.g., depression). However, real-life sleep and circadian problems are not so neatly categorized, particularly in SMI. Hence, the investigators developed the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) to treat a wide range of sleep and circadian problems experienced in SMI.
With NIMH support, including a study in CMHCs, the investigators established that TranS-C engages the target. Yet gaps remain: 1) Thus far, the TranS-C providers have been employed, trained and supervised by the university. The investigators will determine if TranS-C can be effectively delivered by providers within CMHCs. 2) The investigators will test a version of TranS-C that has been adapted to improve the fit and to address potential barriers to scaling TranS-C. The rigorous adaptation process used theory, data and stakeholder inputs. 3) The investigators will study ad hoc adaptations made by providers to TranS-C. 4) The investigators include a Sustainment Phase (1 year), responding to urgent calls to study the sustainability of EBPTs.
This entry describes the Implementation Phase, the first of a three-phase hybrid type 2 effectiveness-implementation trial. In this phase, implementation and effectiveness outcomes of two versions of TranS-C (Standard and Adapted) are compared with CMHC providers who are trained by treatment experts.
Guided by the Replicating Effective Programs (REP) framework, at least 8 CMHC clinic sites will be cluster randomized to either Standard or Adapted TranS-C. Then, within each CMHC site, patients will be randomized to immediate TranS-C or to Usual Care followed by Delayed Treatment (UC-DT). A total of 96 providers and 576 patients. Patients will be assessed pre, mid and post-treatment and at 6 months follow-up. UC Berkeley will co-ordinate the research, facilitate implementation, collect data etc. Providers within an established network of CMHCs will implement TranS-C. 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. SA2 is to evaluate the fit, to the CMHC context, of Standard vs. Adapted TranS-C via provider ratings of acceptability, appropriateness and feasibility. SA3 will examine if better fit, operationalized via provider ratings of acceptability, mediates the relationship between treatment condition and patient outcome. This research will determine if sleep and circadian problems can be effectively addressed in SMI in CMHC settings, test two variations of TranS-C that each have unique advantages and focus on community providers and typical community patients.
