Project STAR aims to examine the feasibility, acceptability, and initial efficacy of a CBT-I supplement to outpatient alcohol and substance use treatment.
Among those who receive treatment for alcohol use disorder (AUD), one in three relapses to problematic drinking within one year of treatment. Thus, additional treatment strategies are needed. Notably, up to 74% of individuals seeking treatment for AUD report co-occurring symptoms of insomnia, while 85% of those seeking SUD treatment report insomnia symptoms. Given the negative impact of insomnia on attention and emotion regulation, insomnia symptoms may decrease patients' abilities to attend to treatment for substance use and manage negative emotions that lead to craving and relapse. This project aims to examine the feasibility, acceptability, and initial efficacy of a CBT-I supplement to substance use treatment. Forty adults who meet diagnostic criteria for AUD or SUD and Insomnia Disorder will receive Cognitive Behavioral Therapy for Insomnia (CBT-I). In order to generate hypotheses regarding the efficacy of CBT-I for individuals who are and are not engaged in substance use treatment, we aim to recruit 20 participants who are engaged in substance use treatment through the community at baseline and 20 participants who are not. Outcomes will be assessed at the end of the active intervention period (6 weeks) and at 6 weeks post-intervention

RECRUITINGRecruitment
The number of participants who complete baseline.
Time frame: Assessed at Post-Treatment (week 6)
Retention
The number of participants who complete all treatment sessions
Time frame: Assessed at Post-Treatment (week 6)
Treatment Satisfaction
The satisfaction rating participants give the treatment.Assessed using the Client Satisfaction Questionnaire; The Client Satisfaction Questionnaire is an 8-item measure of satisfaction with treatment that has been validated in substance use treatment settings. Items are scores from 1 to 4, with higher scores indicating greater satisfaction with treatment.
Time frame: Assessed at Post-Treatment (week 6)
Abstinence
The percentage of days during the past 6 weeks that the participant is abstinent from their drug of choice (alcohol or other substance). Assessed using the Timeline Followback (TLFB); TLFB allows participants to trace their alcohol and drug use back 42 days.
Time frame: Change from baseline to post-treatment (week 6) to follow-up (week 12)
Heavy-Drinking Days
The percentage of days during the past 6 weeks that the participant engages in heavy drinking (\>4/5 drinks/day for women/men). Assessed using the Timeline Followback (TLFB) for alcohol; TLFB allows participants to trace their alcohol use back 42 days.
Time frame: Change from baseline to post-treatment (week 6) to follow-up (week 12)
Substance Use Days
The percentage of days during the past 6 weeks that the participant engages in drug/substance use. Assessed using the Timeline Followback (TLFB) ; TLFB allows participants to trace their drug/substance use back 42 days.

Alcohol Problems
Assessed using the Short Inventory of Problems (SIP); SIP measures adverse consequences of substance use.
Time frame: Change from baseline to post-treatment (week 6) to follow-up (week 12)
Alcohol or Other Drugs as Sleep Aids
Assessed using the daily sleep diary; Sleep Diaries are quotidian questionnaires that measure self-reported sleep quality, sleep time, and daily habits concerning substance use. Diaries will be used to determine if participants used alcohol or other substances specifically to go to sleep
Time frame: Change from baseline to post-treatment (week 6) to follow-up (week 12)
Insomnia severity
Assessed using the Insomnia Severity Index (ISI); ISI will be used as a 7-item measure of insomnia severity in the past two weeks. Items assess difficulty falling or staying asleep, satisfaction with current sleep pattern, interference with daily functioning, the extent to which others notice their sleep problems, and worry/distress related to sleep problems. Response options range from 0 (not at all worried) to 4 (very much worried), with possible total scores ranging from 0 to 28. Participants scoring 10 or higher will be classified as screening positive for insomnia (Morin et al., 2011).114 Notably, self-report is the recommended method of assessment for symptoms of insomnia in adults (Schutte-Rodin et al., 2008).
Time frame: Change from baseline to post-treatment (week 6) to follow-up (week 12)
Total Wake Time
The amount of time the participant is awake after they try to go to sleep. Measured using Daily Diaries and actigraphy.
Time frame: Change from baseline to post-treatment (week 6) to follow-up (week 12)
Sleep quality
Assessed using the daily sleep diary; Sleep Diaries are quotidian questionnaires that measure self-reported sleep quality, sleep time, and daily habits concerning substance use. Diaries will be used to determine if participants used alcohol or other substances specifically to go to sleep.
Time frame: Change from baseline to post-treatment (week 6) to follow-up (week 12)
Dysfunctional beliefs
Assessed using the Dysfunctional Beliefs and Attitudes about Sleep questionnaire (DBAS;Morin, 1994). The DBAS is designed to measure sleep and insomnia-related cognitions.
Time frame: Change from baseline to post-treatment (week 6) to follow-up (week 12)
