BACKGROUND: There is an urgent need for interventions helping children affected by parental problematic alcohol consumption (PAC). Such interventions could target partners to individuals with PAC, partners who often themselves show impaired quality of life and mental health. The aim of this study was to investigate the efficacy of an online self-directed intervention combining components from Community Reinforcement Approach and Family Training (CRAFT) with a parenting training program for concerned significant others (CSOs) sharing a child with a co-parent with PAC.
METHODS: A randomized controlled parallel-group superiority trial compared the efficacy of the online intervention for CSOs sharing a child (3-11 y/o) with a co-parent with PAC (N = 37), to an active control group (N = 39) receiving written psychoeducational material. Assessment of outcomes was conducted at baseline, 3 weeks, 8 weeks and 12 weeks. Primary outcome was children's mental health, while secondary outcomes included parental self-efficacy, CSO mental health and co-parent alcohol consumption and level of dependence. Linear mixed effect models with a factorial time variable were used to model time by group interaction effects.
RESULTS: Recruitment rate was slow and a vast majority of interested CSOs were excluded at baseline assessment, mainly due experience of co-parent violence. The target sample size was not met. The intention to treat analysis did not show any significant time by group effects on either the primary or secondary outcomes during the follow-up period: the CSOs reported a significant reduction in co-parent alcohol consumption and severity of alcohol dependence and showed significant improvements in parental self-efficacy for how to handle effects of co-parent alcohol consumption, but no differences were found between the two conditions.
CONCLUSIONS: The current study found no evidence supporting efficacy of a novel, online self-directed intervention on children's mental health, CSO mental health and co-parent alcohol related outcomes. Engaging in a support program or receiving information appears to initiate behavior change in the CSOs which affects the alcohol consumption and severity of dependence for co-parents with PAC. It is suggested that future studies may preferably focus on CSOs in more severely affected contexts.
