Abstract

Background and aim: Parental substance use is a major public health and safeguarding concern. There have been a number of trials examining interventions targeting this risk factor. We aimed to estimate the effectiveness of psychosocial interventions at reducing parental substance use.                 Design: We used systematic methods to identify trials; pooling data using a random-effects model. Moderator analyses examined influence of parent gender, presence of child in treatment and intervention type.                    Setting: No restrictions on setting.                                                         Participants: Substance using parents of children below the age of 21 years. Interventions: Psychosocial interventions including those that targeted drug and alcohol use only, and drug and alcohol use in combination with associated issues.                                                                                            Measurements: Frequency of alcohol use and frequency of drug use. Findings: We included eight unique studies with a total of 703 participants. Psychosocial interventions were more effective at reducing the frequency of parental alcohol use than comparison conditions at 6-month [standardized mean difference (SMD) = – 0.32, 95% confidence interval (CI) = –0.51 to −0.13, P = 0.001] and 12-month follow-up (SMD = –0.25, 95% CI = –0.47 to −0.03, P = 0.02) and frequency of parental drug use at 12 months only (SMD = –0.21, 95% CI = –0.41 to −0.01, P = 0.04). Integrated interventions which combined both parenting and substance use targeted components were effective at reducing the frequency of alcohol use (6 months: SMD = –0.56, 95% CI = –0.96 to −0.016, P = 0.006; 12 months: SMD = –0.42, 95% CI = –0.82 to −0.03, P = 0.04) and drug use (6 months: SMD = –0.39, 95% CI = –0.75 to −0.03, P = 0.04; 12 months: SMD = –0.43, 95% CI = –0.80 to −0.07, P = 0.02). Interventions targeting only substance use or parenting skills were not effective at reducing frequency of alcohol or drug use at either time-point.                                             Conclusion: Psychosocial interventions should target both parenting and substance use in an integrated intervention.
