Culturally Tailored Cannabis Use Disorder App

Study Overview
=================
Brief Summary
-----------------
The present study aims to address disparities in cannabis use outcomes among African American/Black (hereby referred to as Black) adults with cannabis use disorder (CUD). The specific aims of this study are: (1) to develop a culturally adapted, mobile app for Black cannabis users (CT-MICART) using knowledge from the current research team, published literature, expert opinion, and feedback from the Community Research Advisory Board (CRAB), (2) to pilot test CT-MICART and (3) focus on analysis of data collected as part of Aim 2.

Detailed Description
-----------------
The present study aims to address disparities in cannabis use outcomes among African American/Black (hereby referred to as Black) adults with cannabis use disorder (CUD). African American/Black adults are more likely to endorse cannabis use patterns that are more severe (weekly and blunt use) and meet diagnostic criteria for cannabis use disorder (CUD) than White adults (16.8% vs 10.0%). This finding is alarming as cannabis use disorder is associated with more severe psychosocial risk profiles, including poly-substance use, psychiatric problems, and legal trouble relative to non-CUD use and non-use. Additionally, although Black cannabis users are more likely to report being ready to quit and a recent quit attempt relative to White cannabis users, this population is less likely to seek in-person treatment relative to White cannabis users because of individual (e.g., beliefs about use), community (e.g., neighborhood attitudes about use), and institutional (e.g., healthcare access) factors as well as due to institutionalized racism and discrimination (e.g., more likely to not be listened to by practitioners). Targeted, accessible, and culturally adapted therapeutic programming is needed to reduce risk and improve disparities for poor cannabis-related outcomes among Black adults with cannabis use disorder. These findings are significant because they contribute to heath, social, and psychological health disparities within the Black community. Psycho-sociocultural models of substance use posit that Black individuals may use cannabis and continue using despite cannabis-related problems including cannabis use disorder, to manage psychological distress associated with stressors associated with minority status, such as racial discrimination. Therefore, the present study seeks to develop a culturally adapted, mobile app tailored specifically for Black cannabis users (CT-MICART). Using the expert opinion and feedback from the community Research Advisory Board (CRAB), the investigative team will pilot test CT-MICART and focus on analysis of data collected to help achieve a better culturally tailored app.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety Aid Scale | The Safety Aid Scale will be used to assess change of false safety behavior use over time, being scored on a 5 point scale where higher scores indicate greater use of false safety behaviors. | Baseline appointment and 6-week follow up appointment | 
| Qualitative Interview | The qualitative interview done by the participants will ask them about their experience with the app, what aspects helped, what aspects didn't help, and will allow researchers to adapt and refine the CT-MICART app. | 6-week follow up appointment | 
| Engagement with the CT-MICART app | Behavioral indicators of engagement with the app (>75% of all videos watched and >75% of scheduled skills practiced). | Week 1-6 |
