A Brief Cannabis Use Psychoeducation Intervention for Eating Disorder Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

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.

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.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Knowledge of cannabis use consequences — 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.
  Self-perceived knowledge about consequences of cannabis use will be measured using a 100 point visual analogue scale. Higher scores will indicate greater self-perceived knowledge about the consequences of cannabis use.
• Intention to reduce cannabis use — 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 personal cannabis use will be measured using a 100 point visual analogue scale. Higher scores indicate greater intention to reduce cannabis use.
• Intention to seek cannabis use treatment — 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 will be measured using a 100 point visual analogue scale. Higher scores indicate greater intention to seek cannabis use treatment.
