Feasibility/Acceptability of a Brief Motivational Intervention for Frequent/High-Intensity Cannabis Use

Summary

The study aims to develop a novel brief motivational mobile health (mHealth) intervention for frequent and/or high-intensity cannabis use for non-collegiate young adults. A total of 120 young adults (ages 18-29, not enrolled at or attending a 4-year college or university) will be randomized to receive a mHealth intervention with text messages for five weeks or to an online resource/program with psychoeducation information about cannabis. The mHealth intervention will focus on prompting the young adult to reflect on their journey with cannabis and to reflect on their personal goals and how cannabis is reflected in these goals. Additional mini-modules are included related to topics such as motivations for use, perceived norms and tracking cannabis use. Participants will return to the program each week to reflect on the prior week and reflect on goals for the upcoming week. All participants will complete a program satisfaction survey and complete follow-up assessments at 3- and 6-months post-program.

Interventions

BEHAVIORAL

Brief Motivational Mobile Health (mHealth) Intervention

Participants randomized to the mHealth intervention condition will receive a five-week online program that incorporates weekly text messages. The program will begin with prompting the young adult to reflect on their journey with cannabis and to reflect on their personal goals and how cannabis is reflected in these goals and how their social network may support their goals. Additional mini-modules are included related to topics such as motivations for use, perceived norms and tracking cannabis use. Text messages will be sent weekly to return to the program to prompt reflection and support any goals the participant indicates.

OTHER

Psychoeducational Attention Control (AC)

Participants randomized to the control group will receive a program to learn more about psychoeducational information about cannabis. They also receive psychoeducational material via text messages.
