Preventing alcohol harm: early results from a cluster randomised, controlled trial in Victoria, Australia of comprehensive harm minimisation school drug education.

BACKGROUND: In Australia, the burden of alcohol-attributable harm falls most heavily on young people. Prevention is important, and schools have long been seen as appropriate settings for pre-emptive interventions with this high risk group. This paper evaluates the effectiveness, in relation to alcohol harm prevention, of the Drug Education in Victorian Schools (DEVS) programme, nine months after implementation. This intervention dealt with both licit and illicit drugs, employed a harm minimisation approach that incorporated interactive, skill based, teaching methods and capitalised on parental influence through home activities. METHODS: A cluster randomised, controlled trial of the first ten lessons of the DEVS drug education programme was conducted with year eight students, aged 13-14 years. Twenty-one secondary schools in Victoria, Australia were randomly allocated to receive the DEVS programme (14 schools, n=1163) or the drug education usually provided by their schools (7 schools, n=589). Self-reported changes were measured in relation to: knowledge and attitudes, communication with parents, drug education lessons remembered, proportion of drinkers, alcohol consumption (quantity multiplied by frequency), proportion of student drinkers engaging in risky consumption, and the number of harms experienced as a result of alcohol consumption. RESULTS: In comparison to the controls, there was a significantly greater increase in the intervention students' knowledge about drugs, including alcohol (p≤0.001); there was a significant change in their level of communication with parents about alcohol (p=0.037); they recalled receiving significantly more alcohol education (p<0.001); their alcohol consumption increased significantly less (p=0.011); and they experienced a lesser increase in harms associated with their drinking (p≤0.001). There were no significant differences between the two study groups in relation to changes in attitudes towards alcohol or in the proportion of drinkers or risky drinkers. There was, however, a notable trend of less consumption by risky drinkers in the intervention group. CONCLUSIONS: A comprehensive, harm minimisation focused school drug education programme is effective in increasing general drug knowledge, and reducing alcohol consumption and harm.

Starting to drink: the experiences of Australian lower secondary students with alcohol.

This study describes Australian year eight students' (13-14 years old) experiences with alcohol in terms of communication with parents, initiation into drinking, patterns of consumption, context of use, and harms experienced. The sample comprised 521 year eight students from four state government secondary schools in the state of Victoria. Three of the schools are in Melbourne, the capital of Victoria; the fourth is in a rural center. Female and rural students were more likely to talk to parents about alcohol, but this was not associated with safer drinking. Initiation into drinking was higher among rural students. Rural students also drank more, were more likely to drink without adult supervision, to drink to get drunk, and drink more than planned. Student drinkers experienced just over four alcohol-related harms on average in 12 months, with some indication of greater harm among rural students. Higher levels of drinking by rural students, accompanied by more risky patterns of consumption and the possibility of greater harm, supports prioritizing interventions in rural schools.

Drug education in Victorian schools (DEVS): the study protocol for a harm reduction focused school drug education trial.

BACKGROUND: This study seeks to extend earlier Australian school drug education research by developing and measuring the effectiveness of a comprehensive, evidence-based, harm reduction focused school drug education program for junior secondary students aged 13 to 15 years. The intervention draws on the recent literature as to the common elements in effective school curriculum. It seeks to incorporate the social influence of parents through home activities. It also emphasises the use of appropriate pedagogy in the delivery of classroom lessons. METHODS/DESIGN: A cluster randomised school drug education trial will be conducted with 1746 junior high school students in 21 Victorian secondary schools over a period of three years. Both the schools and students have actively consented to participate in the study. The education program comprises ten lessons in year eight (13-14 year olds) and eight in year nine (14-15 year olds) that address issues around the use of alcohol, tobacco, cannabis and other illicit drugs. Control students will receive the drug education normally provided in their schools. Students will be tested at baseline, at the end of each intervention year and also at the end of year ten. A self completion questionnaire will be used to collect information on knowledge, patterns and context of use, attitudes and harms experienced in relation to alcohol, tobacco, cannabis and other illicit drug use. Multi-level modelling will be the method of analysis because it can best accommodate hierarchically structured data. All analyses will be conducted on an Intent-to-Treat basis. In addition, focus groups will be conducted with teachers and students in five of the 14 intervention schools, subsequent to delivery of the year eight and nine programs. This will provide qualitative data about the effectiveness of the lessons and the relevance of the materials. DISCUSSION: The benefits of this drug education study derive both from the knowledge gained by trialling an optimum combination of innovative, harm reduction approaches with a large, student sample, and the resultant product. The research will provide better understanding of what benefits can be achieved by harm reduction education. It will also produce an intervention, dealing with both licit and illicit drug use that has been thoroughly evaluated in terms of its efficacy, and informed by teacher and student feedback. This makes available to schools a comprehensive drug education package with prevention characteristics and useability that are well understood.
