A Process study and Randomized controlled trial examining the Efficacy and Mechanisms of Motivational interviewing for alcohol Intoxicated young adults admitted to the Emergency Room
Alcohol intoxication
Participants will be randomised to one of two groups using an algorithm implemented in the same software used to collect baseline assessment (secuTrial). Intervention group: The experimental treatment will be a brief motivational intervention (BMI) developed and pre-tested in the first phase of project PREMMIER. BMI will be delivered while in the ER by a qualified research clinician (psychologist, clinical social worker, or nurse) and will last between 20 to 60 minutes. The intervention will use 3 main ingredients, in particular: 1. Relational factors (e.g., empathy, acceptance, collaboration, avoidance of confrontation) 2. Evoking participants’ change talk and strengthening their ability and commitment to change 3. Providing information while supporting participants’ autonomy. Overall, the intervention aims at increasing participants’ motivation to change their drinking behaviours by enhancing discrepancy between their current behaviour and their broader life goals and values. The intervention focuses on helping participants to resolve the latter discrepancy through evoking and planning behaviour change. When necessary, interventionist will discuss and facilitate referral to alcohol treatment. After the session, the interventionist sends a letter summing up the discussion (i.e., context, discussion, aims and encouragements) to the participant. Based on participant’s agreement, booster session by phone will be conducted after 1 week, 1 month, and 3 months. Control group: The control intervention will be a minimal intervention - Brief advice. Brief advice will be delivered in approximately 5 to 10 minutes. It will led by the same research clinicians and will consist of a standardized brief structured feedback and advice to cut down drinking, with referral to specialist services for the more severe patients (based on the Alcohol Use Disorders Identification Test score included in the baseline assessment). Participants will complete a short post-session questionn
