NCT04154631

Brief Summary

The sleep disturbance commonly experienced by individuals with a severe mental illness (SMI) reduces these individuals' capacity to function and contributes to key symptoms. This study will test the effects of a sleep treatment that has been adapted using theory, data and stakeholder inputs to improve the fit for SMI patients treated in community mental health centers (CMHCs), relative to the standard treatment. The investigators will also determine if the adapted and standard versions can improve sleep, improve functioning and reduce symptoms.

Outcome Measures

Primary Outcomes (2)

  • Patient-level Outcome: Patient-Reported Outcomes Measurement Information System - Sleep Disturbance

    Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance Scale. The 8-item short version scale assesses perceived sleep problems (e.g., sleep quality, perception of sleep difficulties) over a 7-day period. Items are rated on a 5-point scale ranging from 1 (not at all) to 5 (very much). Raw scores are summed to produce a single score, resulting in a range from 8 to 40. Raw scores are converted to t-scores using treatment manuals. T-scores range from 30.5 to 77.5. A T-score of 50 indicates the population mean with a standard deviation of 10. Higher scores indicate worse sleep disturbance.

    Baseline, mid-treatment (2 weeks post-baseline for Adapted TranS-C and 4 weeks post-baseline for Standard TranS-C), post-treatment (4 weeks post-baseline for Adapted TranS-C and 8 weeks post-baseline for Standard TranS-C), and 6-month follow-up.

  • Provider-level Outcome: Acceptability Intervention Measure

    Assesses provider perceptions of the acceptability of the treatment intervention using a self-report questionnaire. The 4-item scale is rated on a 5-point scale from 1 (completely disagree) to 5 (completely agree). A total score is calculated by averaging all four items. Total scores range from 1 to 5, with higher scores indicating greater perceptions of acceptability.

    Baseline, mid-treatment (2 weeks post-baseline for Adapted TranS-C and 4 weeks post-baseline for Standard TranS-C), post-treatment (4 weeks post-baseline for Adapted TranS-C and 8 weeks post-baseline for Standard TranS-C).

Secondary Outcomes (6)

  • Patient-level Outcome: Patient-Reported Outcomes Measurement Information System - Sleep Related Impairment

    Baseline, mid-treatment (2 weeks post-baseline for Adapted TranS-C and 4 weeks post-baseline for Standard TranS-C), post-treatment (4 weeks post-baseline for Adapted TranS-C and 8 weeks post-baseline for Standard TranS-C), and 6-month follow-up.

  • Patient-level Outcome: Composite Sleep Health Score

    Baseline, mid-treatment (2 weeks post-baseline for Adapted TranS-C and 4 weeks post-baseline for Standard TranS-C), post-treatment (4 weeks post-baseline for Adapted TranS-C and 8 weeks post-baseline for Standard TranS-C), and 6-month follow-up.

  • Patient-level Outcome: Sheehan Disability Scale

    Baseline, post-treatment (4 weeks post-baseline for Adapted TranS-C and 8 weeks post-baseline for Standard TranS-C), and 6-month follow-up.

  • Patient-level Outcome: The Diagnostic and Statistical Manual of Mental Disorders Cross-Cutting Symptom Measure

    Baseline, post-treatment (4 weeks post-baseline for Adapted TranS-C and 8 weeks post-baseline for Standard TranS-C), and 6-month follow-up.

  • Provider-level Outcome: Intervention Appropriateness Measure

    Baseline, mid-treatment (2 weeks post-baseline for Adapted TranS-C and 4 weeks post-baseline for Standard TranS-C), post-treatment (4 weeks post-baseline for Adapted TranS-C and 8 weeks post-baseline for Standard TranS-C).

  • +1 more secondary outcomes

Other Outcomes (21)

  • Patient-level Outcome: Midpoint of Sleep Measure

    Change from baseline, to mid-treatment, which is 2 or 4 weeks after the beginning of treatment, to post-treatment, which is 6 or 10 weeks after the beginning of treatment, and to 6-month follow-up.

  • Patient-level Outcome: Alcohol Intake

    Change from baseline to post-treatment, which is 6 or 10 weeks after the beginning of treatment, and to 6-month follow-up.

  • Patient-level Outcome: Substances Intake

    Change from baseline to post-treatment, which is 6 or 10 weeks after the beginning of treatment, and to 6-month follow-up.

  • +18 more other outcomes

Study Arms (3)

Standard TranS-C

EXPERIMENTAL

Standard TranS-C is modularized and delivered across eight 50-minute, weekly, individual sessions. It is comprised of 4 cross-cutting interventions featured in every session; 4 core modules that apply to the vast majority of patients; and 7 optional modules used less commonly, depending on the presentation.

Behavioral: Standard Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C)

Adapted TranS-C

EXPERIMENTAL

The process for developing Adapted TranS-C has been iterative and grounded in theory, data and stakeholder feedback. The core elements of the evidence-based theory of change underpinning TranS-C have been retained. Adapted TranS-C is delivered in four 20-minute, weekly, individual sessions.

Behavioral: Adapted Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C)

UC-DT

ACTIVE COMPARATOR

Usual Care Delayed Treatment. Usual care in the partner CMHCs starts with a case manager who co-ordinates care and refers each client for a medication review and to various rehabilitation programs (e.g., health care, housing, nutrition, finding a job, peer monitoring).

Other: Usual Care Delayed Treatment

Interventions

TranS-C is a psychosocial treatment designed to improve sleep and circadian functioning. It is a modular, psychosocial, skills-based approach. In this study, two version of TranS-C will be tested: Standard and Adapted.

Standard TranS-C

The Adapted version was derived from Standard TranS-C. It was developed to improve the fit of the treatment with the CMHC context.

Adapted TranS-C

Usual care in the partner CMHCs typically starts with a case manager who co-ordinates care and refers each client for a medication review and to various rehabilitation programs (e.g., health care, housing, nutrition, finding a job, peer monitoring).
