Abstract

Although media literacy represents an innovative venue for school-based antismoking programming, studies have not systematically compared student impressions of these and traditional programs. This study utilized data from a randomized trial comparing these two types of programs. After each program, students responded to three open-ended questions related to their assigned curriculum. Two coders, blinded to student assignments, independently coded these data. Coders had strong inter-rater agreement (kappa = 0.77). Our primary measures were spontaneously noted overall assessment, enjoyment/interest and the likelihood of changing smoking behavior. Of the 531 participants, 255 (48.0%) were randomized to the intervention (media literacy) group. Intervention participants had more net positive responses [rate ratio (RR) = 1.27, 95% confidence interval (CI) = 1.05, 1.54], more responses rating the program as compelling (RR = 1.63, 95% CI = 1.16, 2.29) and fewer responses rating the program as non-compelling (RR = 0.62, 95% CI = 0.39, 0.97). However, the intervention group was not more likely to suggest that the curriculum was likely to change behavior positively (RR = 0.57, 95% CI = 0.30, 1.06). Findings suggest that although media literacy provides a compelling format for the delivery of anti-tobacco programming, integration of components of traditional programming may help media literacy programs achieve maximal efficacy.

摘要

尽管媒体素养代表了以学校为基础的反吸烟项目的一个创新途径,但研究尚未系统地比较学生对这些项目和传统项目的印象。本研究利用了一项随机试验的数据,比较了这两种类型的项目。在每个项目结束后,学生们回答了与他们所分配课程相关的三个开放式问题。两名对学生分配情况不知情的编码员独立对这些数据进行编码。编码员之间有很强的评分者间一致性(kappa = 0.77)。我们的主要衡量指标是自发记录的总体评估、享受/兴趣以及改变吸烟行为的可能性。在531名参与者中,255名(48.0%)被随机分配到干预(媒体素养)组。干预组有更多的净积极反应[率比(RR)= 1.27,95%置信区间(CI)= 1.05,1.54],更多将该项目评为引人入胜的反应(RR = 1.63,95% CI = 1.16,2.29),以及更少将该项目评为不引人入胜的反应(RR = 0.62,95% CI = 0.39,0.97)。然而,干预组并不更有可能认为该课程可能对行为产生积极改变(RR = 0.57,95% CI = 0.30,1.06)。研究结果表明,尽管媒体素养为开展反烟草项目提供了一种引人入胜的形式,但整合传统项目的组成部分可能有助于媒体素养项目实现最大效果。
