Research on the efficacy of mediated suicide awareness campaigns is limited. The impacts of a state-wide media campaign on call volumes to a national hotline were analyzed to determine if the advertisements have raised awareness of the hotline. We use a quasi-experimental design to compare call volumes from ZIP codes where and when the campaign is active with those where and when the campaign is not active. Multilevel model estimates suggest that the campaign appears to have significantly and substantially increased calls to the hotline. Results from this study add evidence to the growing public health literature that suggests that mediated campaigns can be an effective tool for raising audience awareness.
关于有引导的自杀意识宣传活动效果的研究有限。本研究分析了全州范围的媒体宣传活动对全国热线电话呼入量的影响，以确定广告是否提高了热线的知名度。我们使用准实验设计，比较了广告投放的邮政编码的呼入量，这些地区的广告活动活跃，而其他地区的广告活动不活跃。多层次模型估计表明，该活动似乎显著且大幅增加了热线电话的呼入量。本研究的结果为越来越多的公众健康文献增添了证据，表明有引导的宣传活动可以成为提高受众意识的有效工具。
