To assist intervention developers assess the likely effectiveness of messages designed to encourage greater use of protective behavioral strategies, this study developed and tested the Alcohol Message Perceived Effectiveness Scale (AMPES). Recommendations from the message effectiveness literature were used to guide AMPES development. The resulting scale was administered in online surveys at two time points to Australian drinkers aged 18-70 years (3001 at Time 1 and 1749 at Time 2). An exploratory factor analysis identified the presence of two factors ('effect perceptions' and 'message perceptions') that accounted for 71% of the variance in scores. Internal consistency of scores was good for the overall scale (ω = 0.83) and 'effect perceptions' factor (ω = 0.85), but suboptimal for the 'message perceptions' factor (α = 0.60). Scores on both factors significantly predicted enactment of protective behavioral strategies. The AMPES appears to be an appropriate tool to assess perceived message effectiveness and assist in the development of public health messages designed to reduce alcohol consumption.
为了帮助干预措施的开发者评估旨在鼓励更多使用保护性行为策略的信息的有效性,本研究开发并测试了酒精信息感知有效性量表(AMPES)。信息有效性文献中的建议被用来指导 AMPES 的开发。该量表在两个时间点通过在线调查分发给年龄在 18 至 70 岁的澳大利亚饮酒者(第一次调查时为 3001 人,第二次调查时为 1749 人)。探索性因素分析确定了两个因素(“效果感知”和“信息感知”)的存在,它们解释了分数变化的 71%。总分(ω=0.83)和“效果感知”因子(ω=0.85)的得分内部一致性良好,但“信息感知”因子(α=0.60)的一致性则不太理想。两个因子的得分都显著预测了保护性行为策略的实施。AMPES 似乎是评估感知信息有效性的合适工具,并有助于开发旨在减少饮酒的公共卫生信息。
