The purpose of this study is to investigate the efficacy of a group-based behavioral sleep intervention, and the incremental benefit provided by an adjunct sleep mobile app, on cannabis and sleep outcomes among cannabis dependent Veterans.

Conditions

• Sleep Initiation and Maintenance Disorders

Interventions

BEHAVIORAL

Cognitive Behavioral Therapy for Insomnia (CBT-I)

This is a group-delivered version of the six-session Cognitive-Behavioral Treatment for Insomnia that has been disseminated throughout the VA. It incorporates psychoeducation, diary-based sleep assessment, estimation of sleep scheduling and efficiency, evaluation/mitigation of dysfunctional sleep-related beliefs/ behaviors, generation of sleep prescription (typically restriction), iterative review of sleep efficiency and prescription, and planning for maintenance of gains.

BEHAVIORAL

Cognitive Behavioral Therapy for Insomnia Plus Mobile App (CBT-I-MA)

This is a mobile-app-augmented, group-delivered version of the six-session Cognitive-Behavioral Treatment for Insomnia that has been disseminated throughout the VA. It incorporates psychoeducation, diary-based sleep assessment, estimation of sleep scheduling and efficiency, evaluation/mitigation of dysfunctional sleep-related beliefs/ behaviors, generation of sleep prescription (typically restriction), iterative review of sleep efficiency and prescription, and planning for maintenance of gains. The mobile-app augmentation substitutes a smartphone-based sleep diary with time-stamping of records to mitigate the common postponement of diary recording and consequent loss of validity. The app also records the sleep prescription, making it, along with links to web-based psychoeducational materials, easily accessible to users. The app also provides plots of bed times, wake times, and sleep efficiency over time, with the goal of promoting adherence.

BEHAVIORAL

Desensitization Treatment for Insomnia

This is a group-delivered version of the sham sleep improvement treatment developed by Edinger which purports to "desensitize" the patient to the various aspects of the sleep experience which are presented as distressing.
