采用前后设计、对照组和随访的方法，评价了四种商业录像带对584名大学生艾滋病知识和态度改变的效果。在播放信息录像带之前、之后以及播放后4至6周，分别测量艾滋病知识和态度。此外，研究对象还对每盘录像带进行了几个特定维度的评分，包括整体质量。年龄、性别、以前接触过艾滋病信息以及演讲后是否进行讨论的影响作为协变量进行测量。总的来说，所有四盘录像带都使艾滋病知识有了显著的立即增加（p < 0.001）。这些收益一直持续到后续调查，四盘磁带中的三盘没有受到侵蚀。除了认为艾滋病预防方法的有效性(p <。001)，对艾滋病的态度没有因为观看任何录像带而改变（p大于0.05）。观众的评分显示，其中两盘录像带在整体质量方面更胜一筹（p < 0.05）。视频在其他方面的评分也存在差异。在协变量中，在随访时，演讲后讨论与不讨论与知识获得或态度改变之间没有关系。性别与态度的一个组成部分有关，女性认为艾滋病的流行比男性更严重（p < 0.001）。
The effectiveness of four commercial videotape presentations in changing AIDS knowledge and attitudes among 584 college students was evaluated in a pre-post design with control group and follow-up. AIDS knowledge and attitudes were measured prior to, immediately after, and 4 to 6 weeks following presentation of the informational videotapes. In addition, subjects rated each videotape on several specific dimensions, including overall quality. The effects of age, sex, prior exposure to AIDS information, and presence v absence of post-presentation discussion were measured as covariates. In general, there was a significant immediate increase in AIDS knowledge attributable to all four videotapes (p less than .001). These gains persisted until follow-up, with no erosion for three of the four tapes. With the exception of perceived effectiveness of AIDS prevention methods (p less than .001), attitudes toward AIDS showed no change as a result of exposure to any of the videotapes (p greater than .05). Viewer ratings showed two of the videotapes to be superior in terms of perceived overall quality (p less than .05). There were also differences in ratings of videos on other dimensions. Among the covariates, there was no relationship at time of follow-up between post-presentation discussion v no discussion and either knowledge gain or attitude change. Sex was related to one attitude component, with women perceiving the AIDS epidemic as more severe than men (p less than .001).
