This article describes the 'Partysafe' Christmas campaign which was developed and implemented as part of the Community Mobilisation for the Prevention of Alcohol Related Injury (COMPARI) project in Geraldton, Western Australia, during December 1993. The campaign encouraged the responsible serving of alcohol at parties by providing 'Partysafe' Christmas cards with every purchase of take-away liquor, and through local media promotions. Over 17,000 cards containing four key safe partying recommendations were distributed and the campaign message was reinforced by daily newspaper and radio advertisements. An evaluation survey compared pre and post levels of recommended safe party knowledge and behaviours, within Geraldton and between Geraldton and the control town of Bunbury. Results indicated that 'Partysafe' achieved good coverage and increased the level of knowledge, but not the level of personal practice, of the four safe party messages among people who had encountered the campaign. The study indicated that young people were particularly at risk in party situations because they had poorer safe partying knowledge and attended parties which were less likely to adhere to safe practices. Interestingly, the study also revealed poor discrimination between health promotion campaigns.
