Family-based prevention and multi-component interventions may help prevent alcohol misuse in young people, say new systematic reviews

Readers interested in preventing alcohol misuse in young people will find these two new systematic reviews from the Cochrane Library worth looking at in more detail.

Both reviews have been conducted by researchers from Brookes University in Oxford, who searched for randomised controlled trials including school aged children up to 18 years old.

The first review examined the effectiveness of family-based universal programs for the prevention of alcohol misuse in young people. In family settings, universal prevention typically takes the form of supporting the development of parenting skills including parental support, nurturing behaviours, establishing clear boundaries or rules, and parental monitoring. Social and peer resistance skills, the development of behavioural norms and positive peer affiliations can also be addressed with a universal family-based preventive program.

Most of the studies included in this review reported positive effects of family-based universal programs for the prevention of alcohol misuse in young people. Two studies, each with a large sample size, reported no effects.

The reviewers concluded:

The effects of family-based prevention interventions are small but generally consistent and also persistent into the medium- to longer-term.

The second review examined the effectiveness of universal multi-component programs for the prevention of alcohol misuse in young people. Multi-component prevention programs are defined as those prevention efforts that deliver interventions in multiple settings, for example in both school and family settings, typically combining school curricula with a parenting intervention.

A majority of the studies included in this review reported positive effects of multi-component programs for the prevention of alcohol misuse in young people, with effects persisting into the medium- and longer-term. But a notable proportion of trials reported no statistically significant effects. In seven studies the reviewers were able to assess the impact of single versus multiple components, and only 1 out of the 7 studies clearly showed a benefit of components delivered in more than one setting.

The reviewers concluded:

There is some evidence that multi-component interventions for alcohol misuse prevention in young people can be effective. However, there is little evidence that interventions with multiple components are more effective than interventions with single components.
