About

The CanCope Study is a micro-randomized trial conducted to gather evidence about and compare the effectiveness of a momentary intervention to help young adults cope with cannabis cravings as they attempt to reduce their use.

Full description

The CanCope Study is designed to test the effectiveness of two distinct strategies (mindfulness and distraction) to cope with cannabis cravings in young adults (19 - 25 years) who are attempting to reduce their cannabis use. Cannabis use is determined using a single-item question about the number of days out of the past 30 days the individual used cannabis. Young adults who reported using cannabis >10 out of the past 30 days, who were not pregnant or breastfeeding, and who were not currently in treatment for problems related to substance use were eligible to enroll in this four-week study. The CanCope intervention was delivered to participants through the MetricWire app, which was available for download on the participants' personal smartphones. Participants were asked to complete five ecological momentary assessments (EMA) per day, which asked questions related to cannabis use including one question about current level of craving on a scale of 0 - 10. If a participant reported a craving level >4, a message was sent via the app encouraging the participant to try a mindfulness or distraction coping strategy, or the participant received a thank-you for completing the EMA which served as an attention control.

55 participants in 3 patient groups, including a placebo group

CanCope mindfulness
Active Comparator group
Description:
The CanCope intervention was delivered through the MetricWire app which was available to each participant on their personal smartphone. The intervention included a "push" component which was responsive to a participant's level of craving (based on self-report assessed via EMA) and sent messages to each participant via the MetricWire app according to a decision rule. MetricWire randomized delivery of the push component with a probability of 0.33 for receiving a mindfulness coping strategy, 0.33 for receiving a distraction coping strategy, and 0.33 for receiving a thank-you message (attention control) at each decision point when participants were available for the intervention.

Behavioral: CanCope
