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.
Participants must: 1) be 18-29 years old; 2) reside in Washington State; 3) have valid email address; 4) score on the Insomnia Severity Index (ISI) of 10 or higher, indicating at least a moderate score (score of 2 or more) on one or more of the first three items of the ISI measuring difficulty falling asleep, staying asleep, or waking up too early; 5a) report at least two heavy drinking episodes (4+ drinks for women /gender diverse, 5+ for men in a 2-hour period) in the past month; or 5b) 1 heavy drinking occasion and at least 4 total drinking occasions in the past month; 6) have used cannabis 4+ times in the past month; and 7) did not participate in the R34 pilot feasibility trial on which the current RCT is based.

Brief Behavioral Therapy for Insomnia (BBTI)
BehavioralBrief Behavioral Therapy for Insomnia (BBTI) focuses primarily on stimulus control and sleep restriction as well as sleep hygiene recommendations delivered over 2 in-person sessions and 2 brief telephone boosters and is designed to be implemented by nonspecialists in primary care or other non-clinical settings. The intervention is manualized, and clients utilize sleep diaries and workbook assignments to consolidate recommendations.
Brief Alcohol Screening and Intervention for College Students (BASICS)
BehavioralBrief Alcohol Screening and Intervention for College Students (BASICS) is a manualized brief intervention targeting alcohol use and consequences among high risk drinkers and includes both personalized feedback regarding drinking norms, consequences, and motives for drinking, as well as protective behavioral skills for reducing heavy episodic drinking and related consequences. BASICS is delivered in a motivational interviewing (MI) style (Miller \& Rollnick, 2002) to enhance intrinsic motivation to change drinking and implement protective behavioral strategies. BASICS has been adapted to target marijuana use and has been adapted for use with a variety of populations.
Attention Control
BehavioralAttention Control is comprised of 4 weekly 20-minute check-ins with a study therapists regarding the daily monitoring and mood/functioning. Referrals for additional services will be provided as needed.
Insomnia Severity Index (ISI)
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)
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.
Quantity/Frequency/Peak Alcohol Use Index (QFP) peak item
The Quantity Frequency Peak Alcohol Use Index was used to assess the peak number of standard drinks consumed on their heaviest drinking occasion over the previous month.
Quantity/Frequency/Peak Alcohol Use Index (QFP) quantity item
The Quantity Frequency Peak Alcohol Use Index was used to assess typical drinking quantity using the number of drinks consumed during a typical drinking occasion over the previous month.
Daily Marijuana Questionnaire
The Daily Marijuana Questionnaire was used to assess hours high from cannabis use on each day over a typical week in the past month. Items were summed to create a total score of overall number of hours spent high during a typical week.
Marijuana-Related Consequences
Marijuana Consequences were assessed with a 29-item measure assessing consequences related to marijuana use. Response options range from 0=Never to 4=More than 10 times. Scores are summed to create a total score of problems experienced in the previous 3 months. Possible scores ranged from 0 to 116.
