The School Health and Alcohol Harm Reduction Project (SHAHRP) is an example of a harm reduction education intervention which combines a harm reduction philosophy with skills training, education, and activities designed to encourage positive behavioural change It is a curriculum-based programme with an explicit harm reduction goal and is conducted in two phases over a two year period.

13. Knowledge Safer Attitudes Alcohol Consumption Harms McBride et al., 2004; McKay et al., 2012; Midford et al., 2014

14. Subgroup Analyses Baseline Drinking Behaviour (McBride et al., 2003) Abstainers Supervised Drinkers Unsupervised Drinkers Significantly more influenced by the intervention Significantly more influenced by the intervention

15. Findings Greater Alcohol-related Knowledge Safer Attitudes toward Alcohol Regardless of Baseline Drinking Behaviour

16. Findings Lower Quantity of Alcohol Consumption Reduced Frequency of Alcohol Consumption Fewer self-reported Alcohol-Related Harms from both their own and other peoples’ alcohol consumption Consistently observed in the Unsupervised Drinkers group only

18. Quantity of Alcohol Consumption 10% 21% -2% 6%

19. Alcohol-related harms from own drinking 14% -8% 18% -13%

20. Alcohol-related harms from else drinking -8% -28% -9% -33%

21. Unsupervised Drinkers Higher Risk Group (Bellis et al., 2010) SHAHRP lessons focused on alcohol use experiences in unsupervised contexts
