研究概览
简要总结
The study is about helping teens who are involved in the court system to cut down or quit using marijuana. Teens may be asked to test out an experimental smartphone app, called TECH, that will be used only by teens in this study. This app is a private online community where teens can work towards changing their substance use and other behavior with the help of other anonymous teens. We will use this information to learn how the app may help teens make a change and to improve the TECH app.
详细描述
This multiphase study will establish the feasibility, acceptability, and preliminary efficacy of a novel smartphone app that leverages both intrapersonal and interpersonal mechanisms to promote cannabis-related behavior change among CINI youth ages 14-17. The app, Teen Empowerment through Computerized Health (TECH), will be evaluated as an adjunct to treatment as usual (TAU) at the local family court. Phase 1 (completed Fall 2021) included a series of semi-structured interviews with key individuals, to inform how clinical goals (e.g., reduced cannabis use) will map onto usage goals (e.g., goal-setting, peer networking), features (e.g., expert-moderated forum, notifications) and workflow. Then, Phase 2 (completed Fall 2022) beta tested and iteratively refined the TECH prototype with 10 court-involved, non-incarcerated (CINI) youth. In the current phase of the work, Phase 3, we will conduct a pilot randomized control trial (RCT) with 60 CINI youth to test the TECH app (TAU+TECH) relative to TAU-only.
Specific aims are:
Aim 1. Apply the Behavior Intervention Theory model to develop a user-driven tool (i.e., TECH) that capitalizes on how, why, and when CINI youth would most prefer to engage with a smartphone app to reduce cannabis use.
~Aim 1 was achieved in Phase 1 qualitative interviews with CINI youth, their parents, and behavioral health app developers.
Aim 2. Examine the feasibility and acceptability of the TECH user-driven smartphone app.
