Internet-based A-CRA for Young Adults With Problematic Alcohol Use

Study Overview
=================
Brief Summary
-----------------
The primary aim of the study is to evaluate the feasibility and acceptability of an internet-delivered Adolescent Community Reinforcement Approach (I-A-CRA) with therapist support for young adults (aged 18-24 years) with problematic alcohol use and their caregiver/significant other. Secondary aims include investigating the role of comorbid emotional symptoms, emotion regulation and prosocial behavior in treatment outcomes for the young adults. In a randomized controlled pilot trial, participants (n = 60 young adults as well as an optional accompanying caregiver/significant other) will be recruited from the community through advertisements as well as through clinic referrals in Stockholm, Sweden. Eligible participants will be randomized either to the 10-week I-A-CRA treatment or to an active control group (receiving psychoeducation about alcohol use over the same time frame). In both conditions an optionally accompanying caregiver/significant other will receive a support program in conjunction with the young adult's treatment. Participating young adults will be evaluated with regards to their alcohol use, psychiatric symptoms, emotion regulation, and prosocial behavior at pre-treatment, weekly during treatment, post-treatment, and at a 3-month follow-up. The primary outcome will be feasibility (measured as number of treatment completers; i.e., having completed 5 out of 8 treatment modules), and acceptability (measured by patient satisfaction). Secondary outcomes will include pre- and post-treatment self-rated binge drinking episodes, levels of depression, anxiety and stress, emotion dysregulation, and prosocial behavior. Self-reports regarding stress, emotion dysregulation, and prosocial behavior will be complemented by behavioral measures (computerized tasks).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: I-A-CRA<br>Internet-delivered Adolescent Community Reinforcement Approach: The treatment program consists of 8 extensive treatment modules delivered over 10 weeks with continuous therapist support and guidance. There are two separate treatments for the young adult and the caregiver/significant other. | Behavioral: Internet-delivered Adolescent Community Reinforcement Approach (I-A-CRA)<br>* The intervention is a behavioral internet-based intervention based on the Adolescent Community Reinforcement Approach. The program encompasses text, pictures, videos, and written as well as practical assignments (skills training). The main components of the treatment for the young adult with problematic alcohol use consist of psychoeducation and functional analysis, goal formulation, increasing prosocial behaviors, relapse prevention, problem solving, and communication training. The accompanying significant other receives modules containing information focusing on gaining an understanding of the treatment components aimed at the young adult, as well as communication training to improve communication between the young adult and the significant other.<br>|
| Active Comparator: Psychoeducation alcohol use<br>Psychoeducation focusing on alcohol use: This support program provides 8 brief modules of psychoeducation (alcohol information) over 10 weeks. Participants receive no therapist guidance/support but have the possibility of asking questions to a therapist. There are two separate programs for the young adult and the caregiver/significant other. | Behavioral: Psychoeducation, information on use of alcohol and its effects<br>* The intervention is a behavioural internet-based intervention including psychoeducation focusing on providing information on alcohol, alcohol use, and its effects. The psychoeducation is provided via texts and pictures, and there is a possibility of asking questions to a therapist if needed however no therapist contact is mandatory. There are separate programs directed towards the young adult and the accompanying significant other. The programmes give brief self-help tips at the end. The intervention approximately corresponds to the information given in a primary care setting for someone with problematic alcohol use.<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of treatment completers defined as patients completing 5 or more of the 8 modules of treatment | Outcome used to assess feasibility. | Will be assessed post treatment (11 weeks after treatment initiation) | 
| Client Satisfaction Questionnaire 8 item | Acceptance will be measured as percentage of participants rating their satisfaction as good. Higher score indicates better outcome. Scores range from 8-32. | Will be assessed post treatment (11 weeks after treatment initiation) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Timeline Follow-back - change in time spent doing activities unrelated to drinking | Number of self-reported activities registered that are not related to alcohol consumption over the past week. More episodes is a better outcome. | Will be assessed before treatment initiation, at week 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 of treatment, and post treatment (11 weeks after treatment initiation) | 
| Alcohol Use Disorders Identification Test - change pre to post treatment | Self-reported screening of alcohol use disorder symptoms. Higher scores indicate worse outcome. Scores range from 0-40. | Will be assessed before treatment initiation and post treatment (11 weeks after treatment initiation) | 
| Difficulties in Emotion Regulation Scale 16 item - change over timepoints | Self-report scale measuring emotion dysregulation. Higher scores indicate worse outcome. Scores range from 16-80. | Will be assessed before treatment initiation, at week 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 of treatment, and post treatment (11 weeks after treatment initiation) | 
| Depression Anxiety Stress Scale-21 - change pre to post treatment | Self-report scale measuring symptoms of depression, anxiety and stress over the past week. Higher scores indicates worse outcome. Scores range from 0-42. | Will be assessed before treatment initiation and post treatment (11 weeks after treatment initiation) | 
| Timeline Follow-back - change in self-rated alcohol consumption | Number of heavy drinking episodes (heavy drinking defined as 4 or more drinks per drinking occasion in women and 5 or more for men) over the past week. Fewer episodes is a better outcome. | Will be assessed before treatment initiation, at week 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 of treatment, and post treatment (11 weeks after treatment initiation) |
