Primary prevention for alcohol misuse in young people
Abstract
Background
Alcohol misuse is a cause of concern for health services, policy makers, prevention workers, the criminal justice system, youth workers, teachers and parents.
Objectives
1. To identify and summarize rigorous evaluations of psychosocial and educational interventions aimed at the primary prevention of alcohol misuse by young people.
2. To assess the effectiveness of primary prevention interventions over the longer‐term (> 3 years).
Search methods
Databases searched (no time limits): Project CORK, BIDS, PSYCLIT, ERIC, ASSIA, MEDLINE, FAMILY‐RESOURCES‐DATABASE, HEALTH‐PERIODICALS‐DATABASE, EMBASE, BIDS, Dissertation‐Abstracts, SIGLE, DRUG‐INFO, SOMED, Social‐Work‐Abstracts, National‐Clearinghouse‐on‐Alcohol‐and‐Drug‐Information, Mental‐Health‐Abstracts, DRUG‐database, ETOH (all searched Feb‐June 2002).
Selection criteria
1. randomised controlled and non‐randomised controlled and interrupted time series designs.
2. educational and psychosocial primary prevention interventions for young people up to 25 years old.
3. alcohol‐specific or generic (drugs; lifestyle) interventions providing alcohol outcomes reported.
4. alcohol outcomes: alcohol use, age of alcohol initiation, drinking 5+ drinks on any one occasion, drunkeness, alcohol related violence, alcohol related crime, alcohol related risky behaviour.
Data collection and analysis
Stage 1: All papers screened by one reviewer against inclusion criteria.
Stage 2: For those papers that passed Stage 1, key information was extracted from each paper by 2‐3 reviewers.
Main results
20 of the 56 studies included showed evidence of ineffectiveness. No firm conclusions about the effectiveness of prevention interventions in the short‐ and medium‐term were possible. Over the longer‐term, the Strengthening Families Program (SFP) showed promise as an effective prevention intervention. The Number Needed to Treat (NNT) for the SFP over 4 years for three alcohol initiation behaviours (alcohol use, alcohol use without permission and first drunkeness) was 9 (for all three behaviours). One study also highlighted the potential value of culturally focused skills training over the longer‐term (NNT=17 over three‐and‐a‐half years for 4+ drinks in the last week).
Authors' conclusions
1. Research into important outcome variables needs to be undertaken.
2. Methodology of evaluations needs to be improved.
3. The Strengthening Families Programme needs to be evaluated on a larger scale and in different settings.
4. Culturally‐focused interventions require further development and rigorous evaluation.
5. An international register of alcohol and drug misuse prevention interventions should be established and criteria agreed for rating prevention intervention in terms of safety, efficacy and effectiveness.
Plain language summary
Primary prevention for alcohol misuse in young people
Many studies that have evaluated educational and psychosocial prevention programmes were considered and appraised in this systematic review. A number of programmes showed evidence of ineffectiveness. Those that reported longer‐term evaluations (over three years follow‐up) were examined in more detail and several promising studies were re‐analysed to provide a better indication of the potential impact of the prevention programme. On the basis of this re‐analysis, the Strengthening Families Programme (SFP) in particular but also culturally focused skills training appear to offer promise. However, all of the studies included in the review showed some methodological weaknesses and it is therefore necessary to replicate these studies with more robust design and analysis, and across different settings.
