Overview
Brief Summary
This study is designed to evaluate an integrated intervention to reduce alcohol and marijuana use and consequences and improve sleep among young adults with comorbid heavy episodic drinking, marijuana use, and sleep impairment.
Detailed Description
This study is designed to evaluate an integrated brief intervention to reduce alcohol and cannabis use and consequences and improve sleep among young adults (YA) with comorbid heavy episodic drinking (HED), cannabis misuse, and sleep impairment. HED in YA is an important public health problem; consequences include accidental injury and death, academic/work problems, unsafe and unwanted sex, and development of alcohol use disorders. Many YA with HED also use cannabis and experience increased harm as a result. Sleep impairment is common and problematic among YA, identified as one of 5 leading barriers to academic success for students and an important risk factor for mental health problems and suicide in YA. More than 75% of YA report frequent daytime fatigue, 27% extreme distress related to sleep problems, and more than 1 in 4 are at high risk for insomnia. Alcohol use has been linked to insomnia in adolescent, YA, and older adult populations, with bidirectional causal links between alcohol use and impaired sleep. Comorbidity of HED and sleep impairment is associated with increased consequences of alcohol use and exacerbates risk of accidents (including automobile accidents), impaired decision-making, and work and academic difficulties. Similar bidirectional relations exist with cannabis use and sleep, and co-use of these substances may be particularly harmful for sleep. Despite these risks, alcohol and cannabis prevention programs rarely target sleep directly, and the majority of YA sleep interventions either focus on sleep hygiene broadly in the absence of specific strategies to improve sleep or reduce alcohol/cannabis use or have insufficient sample size and duration to truly evaluate impacts on sleep or related comorbid alcohol or cannabis use. Building on the investigators' successful R34 intervention development project, the current study addresses these gaps by evaluating efficacy of integrating a brief sleep intervention (BBTI) with an efficacious brief alcohol and cannabis intervention (BASICS/Cannabis BMI) to increase magnitude and duration of effects on sleep and alcohol and cannabis misuse among a diverse community sample of YA with comorbid insomnia, HED, and cannabis use. Given bidirectional influences between sleep impairment and alcohol/cannabis misuse leading to significant public health challenges for this population, an efficacious integrated treatment is imperative. Impact will be evaluated in a RCT comparing efficacy of telehealth-delivered, integrated BASICSSLEEP to BASICS/BMI only (BASICS+), BBTI only (SLEEP), and Attention control (AC). Surveys and daily diaries will assess alcohol, cannabis, and sleep at baseline, post-treatment, 3-, 6-, 12-, and 18-months. Specific aims are: (1) Evaluate comparative efficacy of BASICSSLEEP, BASICS+, and SLEEP in reducing alcohol/cannabis use and consequences and improving sleep; (2) Evaluate moderators of efficacy for integrated and monotherapies; and (3) Use diary data to evaluate temporal sequencing of effects and duration/decay over time. Findings will remedy important gaps in the literature and result in a scalable, accessible new resource to address this important and costly comorbidity.

Arms & Interventions
BASICSSLEEP
The BASICSSLEEP intervention will integrate BASICS feedback and the Motivational Interviewing (MI) process described in the BASICS arm with Brief Behavioral Therapy for Insomnia (BBTI) content and materials. The BASICS + SLEEP intervention will be implemented in 2 sessions of 45-75 minutes and 2 telephone booster sessions. The investigators will follow BBTI procedures, including provision of a physiological rationale for insomnia and the importance of behavioral strategies to regulate sleep; introduction of sleep hygiene; discussion of factors that can impede duration and quality of sleep; introduction of sleep restriction and stimulus control strategies and negotiation of an initial sleep restriction schedule; and follow-up evaluation of success and continued refinement to achieve sleep efficiency goals. Booster contacts serve as opportunities to adjust the sleep restriction schedule, problem-solve challenges, and further build motivation.

BASICS+
The BASICS+ condition will meet for 2 sessions of 45-75 minutes. Content depends on the degree to which participants discuss the feedback, have questions, and/or explore behavior change options. Therapists review feedback components with participants, eliciting personally relevant reasons to change as domains are explored. When the participant is ambivalent about change, therapists work with them to explore and resolve that ambivalence. The method is non-confrontational and utilizes exploration of personalized graphic feedback (i.e., frequency, quantity, and peak use alongside perceived and actual norms for alcohol/MJ use) to increase motivation for change by highlighting ways alcohol and/or marijuana use could be incongruent with goals or values. Beliefs, expectations, and motives for use are discussed as are strategies to minimize risks and consequences. Booster sessions address questions and problem-solve challenges that have arisen since the session.

SLEEP
The SLEEP intervention will be implemented in 2 sessions of 45-75 minutes and 2 telephone booster sessions. The investigators will follow BBTI procedures, including provision of a physiological rationale for insomnia and the importance of behavioral strategies to regulate sleep; introduction of sleep hygiene; discussion of factors that can impede duration and quality of sleep; introduction of sleep restriction and stimulus control strategies and negotiation of an initial sleep restriction schedule; and follow-up evaluation of success and continued refinement to achieve sleep efficiency goals.

Attention Control
Attention Control (AC) participants complete all assessments (survey, daily, Fitbit, BAC) yoked to participants in the 3 active interventions, and attend the Zoom training to verify identity, orient to the Fitbit \& BAC monitoring, and provide rationale and instructions for daily diaries. To better control for time and attention, AC participants attend 4 weekly Zoom check-ins (\~20 minutes) in which clinically trained staff inquire about challenges encountered in monitoring, observations from monitoring, check in on mood/functioning, and provide referrals as needed. All conditions including AC receive community referrals to address substance uses, sleep, and mental health concerns. No participant is deprived of services; service use is tracked to assist with interpreting outcomes. AC participants will be offered BASICSSLEEP after completing 18-month follow-up.
Intervention: Attention Control
Outcomes
Primary Outcomes
Insomnia Severity Index (ISI)
Time Frame: Baseline, Post-Intervention (7 weeks post-Baseline), 3 Month Follow-up (3 months post-Baseline), 6 Month Follow-up (6 months post-Baseline), 12 Month Follow-up (12 months post-Baseline), 18 Month Follow-up (18 months post-Baseline)
The Insomnia Severity Index is a 7-item measure that assesses the severity of both nighttime and daytime aspects of insomnia. Response options utilized a 5-point Likert scale ranging from 0-4 where "0" reflected low symptom endorsement and "4" reflected high symptom endorsement. Responses across the 7 items are summed to create a Total Score. Total Scores range from 0 to 28. Total scores of 0-7=No clinically significant insomnia, 8-14=subthreshold insomnia, 15-21=clinical insomnia (moderate severity), and 22-28=clinical insomnia (severe).
Patient-Reported Outcomes Information System Short Form v1.0 Sleep-Related Impairment 8a (PROMIS SF8 v1.0 SRI)
Time Frame: Baseline, Post-Intervention (7 weeks post-Baseline), 3 Month Follow-up (3 months post-Baseline), 6 Month Follow-up (6 months post-Baseline), 12 Month Follow-up (12 months post-Baseline), 18 Month Follow-up (18 months post-Baseline)
The Patient-Reported Outcomes Information System Short Form v1.0 Sleep Related Impairment 8a (8-items) assesses self-reported perceptions of impairment due to sleep problems. Response options range from 1=Not at all to 5=Very much and are summed to create a raw score (range 8-40). Raw scores are transformed to T-scores with a population mean of 50 and a standard deviation (SD) of 10, where higher scores indicate greater impairment due to sleep problems. For example, a T-score of 60 is one SD worse than average, whereas a T-score of 40 is one SD better than average.
