Overview
The goal of this clinical trial is to learn if Therabot-CALM (Cannabis, Anxiety, Low Mood) has acceptability among users and could work to improve the symptoms of persons with cannabis use disorder and anxiety and/or depression. The main question it aims to answer is:
What is the usability, feasibility, and acceptability of Therabot-CALM in persons with Cannabis Use Disorder and Anxiety and/or Depression?
Participants will
- Take a screening questionnaire
- Participate in two virtual 1-hour interviews to provide feedback on app design and suggest features.
- Engage with Therabot-CALM in a 4-week clinical trial and provide feedback on their app experience in a third virtual interview
Description
Participants will complete a two-stage screening process via REDCap to determine their eligibility for enrollment. Participants who meet criteria and provide informed consent will be enrolled and participate in three interviews and the 4-week clinical trial.
After the first interview, researchers will fine-tune Therabot-CALM based on feedback received during the interview. After the second interview, experts by experience (EBEs) will engage with Therabot-CALM at least once per day for 4 weeks. After the clinical trial period, participants will receive an email with a link to complete the post-intervention measures delivered via REDCap, including the System Usability Scale (SUS), Treatment Acceptability and Adherence Scale (TAAS), Cannabis Use Disorders Identification Test - Revised (CUDIT-R), the Daily Sessions, Frequency, Age of Onset, and Quantity of Cannabis Use Inventory (DFAQ-CU), the 9-item Patient Health Questionnaire for depression (PHQ-9), and the 7-item generalized anxiety disorder screener for DSM-5 (GAD-7). Participants will then be asked to return for a third interview to provide feedback on their experience with Therabot-CALM.
Researchers will use the IDEAS (Innovate, Develop, Evaluate, Adapt, Scale) Impact Framework to plan and conduct three, one-on-one interviews with a trained research assistant (RA). Each interview script will be developed using the IDEAS Impact Framework and follow a semi-structured design, such that the RA will follow a set of questions, with as-needed probing for follow-up. Interviews will be recorded via a virtual platform.
