Plain English Summary

Background and study aims
Alcohol problems are stigmatizing not only for the people drinking themselves but also for their concerned significant others (CSO's). It has become more and more evident over the last decades that the second hand effects of alcohol- or other dependence problems - are huge both at a personal and societal level. Being a CSO of someone with Alcohol Use Disorder is associated with increased levels of both mental health problems and somatic disorders. Despite this many relatives refrain from seeking help due to e.g. feelings of shame and failure.
Web-based interventions have advantages due to possible anonymity and accessibility, facilitating for people who otherwise wouldn't seek help to take part of treatment programs. For this study a web-based self-help program consisting of four modules of Community Reinforcement Approach and Family Training (CRAFT) was developed with the intention of helping CSO's increasing their psychological health and via new strategies increasing the possibility of their loved ones lowering their alcohol consumption and entering treatment.
Different parental management training programs (PMT's) have shown a lot of positive results during the last decades. The programs often aim at reinforcing positive parental behaviors and strengthening the parent-child relationship. One such Swedish program called ABC (Alla barn I centrum – All Children in the Center) has been used as an add-on feature for parents with a child between 3-11 y/o to investigate if this enhances the effects of the program, especially on the SDQ-outcome.

Who can participate?
Anyone over 18 years old who has a close relationship with a person with alcohol use disorder.

What does the study involve?
Participants are recruited from the Swedish public via websites and online advertisement. For participation they must first register as a user on one of the online help sites Alkoholhjä (the Alcohol help) or Anhörigstö (help for relatives). After registration participants fill out questionnaires which works both as inclusion/exclusion and baseline measurement. Participants are divided with regards of having children in the right age or not. Participants who do not share a child with their IP are randomized into one of two groups: either access to the full web-based self-help CRAFT-program or an educational material (control group). Parents who share a child between 3-11 y/o with their IP are randomized to one of two groups: either access to the full web-based self-help CRAFT-program with the ABC add-on or an educational material. After three months the participants from both the control groups receive access to the full program.

What are the possible benefits and risks of participating?
We have not been able to detect any risks of participation in the study. Answering questions about ones own or a concerned significant others use of alcohol/drugs and how this might effect shared children can be associated with negative emotions. The possible benefits of participation outweighs this given that it might help organizing the present situation that for many concerned significant others is perceived as rather (or very) chaotic. It might also lead to a higher overall quality of life for the participant and a safer environment for children living with parental alcohol or drug problems.
If this project is successful it will make available an evidence based, easy access, self-help program for CSO's possibly helping many thousands of people who otherwise wouldn't receive any help.

Alcohol use disorder, mental health among concerned significant others


Participants who are concerned significant others (CSO) of an identified person (IP) with alcohol use disorder (AUD), but do not present AUD themselves, will be recruited from the general public.
This study involves three subgroups:
A. Parents who share a child (3-11 years) with a person with AUD
B. CSOs dealing with severe problems (CSOs mental health, IP illicit drugs or partner violence from IP)
C. CSOs without severe problems or children (3-11 years)
Included participants in each subgroup are randomized 1:1 to:
Arm 1: Sequential four-module self-help program comprising psychoeducation and exercises from Community Reinforcement Approach And Family Training (CRAFT), with therapist support as needed.
Arm 2: Basic psychoeducation about alcohol use disorder (AUD), being a concerned significant other to someone with AUD and where to look for further help.
Primary outcome will be the participant’s mental health. Additional outcomes will cover the IP's drinking and treatment seeking as well as parent self-efficacy, parent-child relationship and child’s mental health (for parents). Measures will be collected pre-, mid- and post-treatment, and three times during a two-year follow-up period.

Participants eligible for inclusion will be automatically randomised (allocation tickets drawn from a predetermined block-randomised scheme that is reshuffled prior to each draw; no stratification) on accessing their assigned (blinded) treatment program for the first time.

The therapists providing program-support are located at the Centre for dependency disorders in Stockholm, Sweden

The control group will be given access to a brief psychoeducation program, split into four modules and distributed in the same manner as the intervention program (modules made available as completed, although with a minimum 1-week waiting period).
