Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

CanCope Intervention

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.

Group Type EXPERIMENTAL

CanCope

Intervention Type BEHAVIORAL

Messages prompted participants to use mindfulness-based or distraction-based coping strategies, or a thank-you message which served as an attention control. If participants reported elevated craving (4 or greater) prior to a decision point, they received either a coping strategy message or a control message. If participants reported craving levels of less than 4 they received a control message.
