Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Mental illness is often severe, chronic and difficult to treat. The sleep disturbance commonly experienced by individuals with a severe mental illness reduces capacity to function and contributes to key symptoms. This study seeks to determine if an intervention to improve sleep can improve functioning and reduce symptoms and impairment. The investigators will conduct this study in community mental health centers to ensure that the results contribute to closing the worrisome gap between research and practice and to ensure that the findings are generalizable to the real world.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Despite advances in treatment, severe mental illness (SMI) remains common, chronic and difficult to treat. SMI is defined as having at least one mental disorder that lasts for 12-months and leads to substantial life interference. Sleep and circadian dysfunctions are among the most prominent correlates of SMI, yet have been minimally studied in ways that reflect the complexity of the sleep problems experienced by people with SMI. In SMI, sleep and circadian dysfunction undermines affect regulation, cognitive function and physical health, predicts 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 where features of insomnia overlap with hypersomnia, delayed sleep phase and irregular sleep-wake schedules. Accordingly, the investigators aim to test the hypothesis that a Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) will improve functional impairment, disorder-focused symptoms and sleep and circadian functioning. The investigators will recruit participants across Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnoses and across common sleep and circadian problems. The elements of TranS-C are efficacious across SMI in research settings with research-based providers. The next step is to test TranS-C in community settings with community-based providers. Accordingly, the investigators propose to conduct an 'efficacy in the real world' randomized controlled trial within Alameda County Behavioral Health Care Services (ACBHCS), the community mental health center (CMHC) for Alameda County. The investigators will recruit 120 adults diagnosed with SMI and sleep and circadian dysfunction within ACBHCS. Individuals will be randomly allocated to TranS-C (n = 60) or 6-months of Usual Care followed by Delayed Treatment with TranS-C (UC-DT; n = 60). TranS-C is modularized and delivered across eight to twelve 50-minute, weekly, individual sessions. All participants will be assessed before, immediately following treatment (ie. 9-14 weeks later) and again 6 months later.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

TranS-C

The Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) is comprised of cross-cutting interventions, 'core modules' and 'optional modules'. TranS-C is derived and adapted from our previous disorder-focused research, firmly grounded in basic science and treatment literature.

Group Type EXPERIMENTAL

Transdiagnostic Intervention for Sleep and Circadian Dysfunction

Intervention Type BEHAVIORAL

The intervention is a modular treatment composed of core modules that are given to all participants and modules that are delivered based on the need/s of the participants. The interventions are all cognitive behavioral.

UC-DT

Usual Care, Delayed Treatment (DT) is comprised of a case manager who co-ordinates care and refers each client for a medication review and to rehabilitation programs. At the end of 6-months in UC-DT, the participants will receive TranS-C.

Group Type ACTIVE_COMPARATOR

Intervention Type BEHAVIORAL

The intervention is a modular treatment composed of core modules that are given to all participants and modules that are delivered based on the need/s of the participants. The interventions are all cognitive behavioral.
