Official title
A Brief Psychoeducation Intervention to Address Cannabis Use Amongst Patients Seeking Eating Disorder Treatment: A Single Blind Randomized Control Trial
Overview
The goal of this clinical trial is to learn if providing eating disorder patients with education about the consequences of cannabis (marijuana) use on mental health, gastrointestinal symptoms, eating disorder symptoms, and eating disorder treatment effectiveness increases their knowledge about the cannabis use consequences, intention to reduce cannabis use, and motivation to seek treatment for their cannabis use. The main questions this study aims to answer are: 1. Does education about consequences of cannabis use increase eating disorder patients' knowledge about the risks of cannabis use? 2. Does education about the consequences of cannabis use increase intention to reduce cannabis use and seek cannabis use treatment among those with eating disorders? 3. Does cannabis use interfere with how successful eating disorder treatment is for eating disorder patients? All participants will receive 20 weeks of eating disorder treatment. In week 1 of treatment, participants will either be assigned to receive education about cannabis use consequences, or be assigned to a control condition where they receive education about consequences of poor sleep. Participants will be asked to complete a number of questionnaires that measure knowledge about cannabis use consequences, intention to reduce use and seek cannabis use treatment, eating disorder symptoms, and cannabis use habits. Researchers will assess how effective providing education about cannabis use consequences is on changing knowledge about cannabis use risks, intention to reduce use, and intention to seek cannabis use treatment. It will also be examined if effectiveness of eating disorder treatment is related to cannabis use habits.
Interventions
- Other Psychoeducation about risks of cannabis use
This intervention will provide psychoeducation to eating disorder patients about the risks of using cannabis on mood, anxiety, sleep, substance use, gastrointestinal symptoms, eating disorder symptoms, and eating disorder treatment outcomes. - Other Placebo control: Sleep hygiene psychoeducation
Eating disorder patients in the control condition will receive psychoeducation about impacts of poor sleep on mental health and eating disorder treatment outcomes, and strategies to improve sleep hygiene.
Primary outcome measures
- Knowledge of cannabis use consequences [Time frame: Will be measured at baseline (i.e. 5 minutes into Session 1 of treatment for eating disorders before cannabis psychoeducation is administered), and again at 140 minutes into Session 1 of treatment for eating disorders.]
- Intention to reduce cannabis use [Time frame: Will be measured at baseline (i.e. 5 minutes into Session 1 of treatment for eating disorders before cannabis psychoeducation is administered), and again at 140 minutes into Session 1 of treatment for eating disorders.]
- Intention to seek cannabis use treatment [Time frame: Will be measured at baseline (i.e. 5 minutes into Session 1 of treatment for eating disorders before cannabis psychoeducation is administered), and again at 140 minutes into Session 1 of treatment for eating disorders.]
Secondary outcome measures (5)
- Motivations for cannabis use [Time frame: Measured at baseline (i.e. Week 1 of CBT for eating disorders) and through treatment completion (i.e. Week 20 of CBT for eating disorders).]
- Cannabis use frequency [Time frame: Weekly use will be monitored for 20 weeks using a Likert-type question. The Daily Sessions, Frequency, Age of Onset, and Quantity of Cannabis Use Inventory will be measured twice during Week 1 and Week 20 of CBT for eating disorders]
- Eating disorder symptoms [Time frame: Administered at Week 1 (baseline) and Week 20 of CBT for eating disorders.]
- Impairment caused by eating disorder [Time frame: Administered at Week 1 and Week 20 of CBT for eating disorders.]
- Problematic cannabis use [Time frame: Administered at Week 1 and Week 20 of CBT for eating disorders.]
