Cognitive Behavioral Therapy for Insomnia in Cannabis Users
Behavioral: Cognitive Behavioral Therapy for Insomnia in Cannabis Users
Each CBTi-CB therapy session will review the previous week of sleep/wake diaries and summarize key sleep parameters with participants. The treatment will address cannabis use by increasing use of appropriate coping strategies and improving self-efficacy to manage insomnia and next-day consequences. The content includes: (1) Sleep Scheduling Strategies to consolidate sleep using behavioral strategies that increase the drive for sleep and stabilize the circadian timing system; (2) Sleep Hygiene to discuss behaviors, substances, and environmental conditions that can help or hinder sleep; (3) Cognitive Therapy aims to identify and alter dysfunctional beliefs about sleep and functioning that contribute to insomnia; (4) Counter-Arousal Strategies address ruminative thoughts and increased body tension interfering with ability to fall or return to sleep; (5) Relapse Prevention for Insomnia reviews treatment gains and the behavioral and cognitive strategies that were most helpful.
Other Name: Cognitive Behavioral Therapy
Placebo Comparator: Sleep Education
Psycho-education on sleep and sleep hygiene
Behavioral: Sleep Education
The SE condition will be matched to the CBTi-CB condition in terms of level of attention and the non-specific aspects of receiving social support from a study therapist, without providing individualized recommendations. The current content includes: (1) Insomnia History of the participant, including triggers that initiated the problem, duration, severity, and frequency, premorbid sleep characteristics, and previous sleep treatments; (2) Sleep Education about why we sleep, sleep stages, sleep regulation at night, and sleep changes across lifespan; (3) Substance Use and Sleep and the effects of cannabis and other licit and illicit substances on sleep; (4) Environmental Factors that contribute to a sleep-conducive environment; (5) Lifestyle Factors like the effects of diet, exercise, and napping on sleep; (6) Sleep Maintenance Strategies to review treatment gains from the participant's perspective and emphasize the principles covered to maintain sleep improvements.
- Change from baseline Insomnia Severity Index score at study completion [ Time Frame: 12 Weeks ]
The Insomnia Severity Index (ISI) is a brief self-report instrument measuring the patient's perception of both nocturnal and diurnal symptoms of insomnia.
The ISI comprises seven items assessing the perceived severity of difficulties initiating sleep, staying asleep, and early morning awakenings, satisfaction with current sleep pattern, interference with daily functioning, noticeability of impairment attributed to the sleep problem, and degree of distress or concern caused by the sleep problem.
