Clinical Trial Summary

This study will compare the efficacy of telemedicine-delivered cognitive behavioral therapy for insomnia tailored for people using cannabis for sleep (CBTi-CB-TM) to telemedicine-delivered sleep hygiene education (SHE-TM) on sleep, cannabis use, and daytime functioning. We will also evaluate the effects of CBTi-CB-TM on fundamental sleep regulatory system - homeostatic sleep drive - and its association with clinical outcomes.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Frequency of cannabis use as measured by the Timeline Followback (TLFB)	The TLFB is an interviewer-administered calendar-guided instrument that is the gold standard tool for assessing daily substance use.	Up to 6 months after intervention, approximately 32 weeks
Primary	Insomnia Severity Index (ISI) total score measured by the Insomnia Severity Index (ISI)	The ISI is a 7-item questionnaire used to examine insomnia severity over the past 2 weeks. Scores range from 0-28 with higher scores indicating greater insomnia symptom severity.	Up to 6 months after intervention, approximately 32 weeks
Primary	Mental Composite Score (MCS-12) as assessed by the 12-item Short-Form Health Survey (SF-12)	The MCS-12 is a composite score derived from the 12-item Short-Form Health Survey quality of life measure. Scores range from 0-100 with higher scores indicating better health.	Up to 6 months after intervention, approximately 32 weeks
