Combining online Community Reinforcement and Family Training (CRAFT) with a parent-training programme for parents with partners suffering from alcohol use disorder: study protocol for a randomised controlled trial

INTRODUCTION: Partners and children of individuals with alcohol use disorder (AUD) present with impaired quality of life and mental health, yet seldom seek or participate in traditional supportive interventions. Engaging the parent/partner without AUD in treatment is a promising way of supporting behavioural change in both the child and the parent with AUD. Universal parent-training (PT) programmes are effective in increasing children’s well-being and decreasing problem behaviours, but have yet to be tailored for children with a parent with AUD. Community Reinforcement Approach And Family Training (CRAFT) programmes are conceptually similar, and aim to promote behavioural change in individuals with AUD by having a concerned significant other change environmental contingencies. There has been no study on whether these two interventions can be combined and tailored for partners of individuals with AUD with common children, and delivered as accessible, online self-help. METHODS AND ANALYSIS: n=300 participants with a child showing mental health problems and partner (co-parent) with AUD, but who do not themselves present with AUD, will be recruited from the general public and randomised 1:1 to either a four-module, online combined PT and CRAFT programme or a psychoeducation-only comparison intervention. Primary outcome will be the child’s mental health. Additional outcomes will cover the partner’s drinking, the participants own mental health and drinking, the child’s social adjustment, treatment seeking in all three parties and parental self-efficacy. Measures will be collected preintervention, mid-intervention and postintervention, and three times during a 2-year follow-up period. Data will be analysed using mixed-effects modelling. ETHICS AND DISSEMINATION: This study has been approved by the Stockholm Regional Ethical Review Board (2016/2179-31). The results will be presented at conferences and published as peer-reviewed publications. TRIAL REGISTRATION NUMBER: ISRCTN38702517; Pre-results.
