Drawing on the notion of the drench hypothesis proposed by Greenberg (1988), the author proposes a preliminary theoretical framework to explain "drenching" effects of dramatic media. Three drench variables-perceived realism, role identification, and media involvement-were identified and tested regarding their role in mediating the impact of virus disease portrayals on health locus-of-control belief orientations. Participants in the experimental condition watched the movie Outbreak (a portrayal of an outbreak of a deadly virus disease). Perceived realism, role identification, and media involvement were measured concerning the movie depiction of the virus disease. The findings indicate that the dramatized portrayal significantly weakened the viewers' beliefs in self-controllability over health and strengthened their beliefs in chance outcomes of health. Beliefs in provider control over health were affected by the viewers' perception of realism regarding the movie portrayals. Effects of role identification were different between male and female viewers. The results are discussed in relation to drench analysis as a theoretical approach to media effects.
借鉴格林伯格（1988年）提出的“沉浸假说”概念，作者提出了一个初步的理论框架来解释戏剧化媒体的“沉浸”效应。确定了三个沉浸变量——感知现实性、角色认同和媒体参与度，并测试了它们在介导病毒疾病描绘对健康控制点信念取向影响方面的作用。实验组的参与者观看了电影《极度恐慌》（一部关于致命病毒疾病爆发的描绘）。针对电影中病毒疾病的描绘，测量了感知现实性、角色认同和媒体参与度。研究结果表明，戏剧化描绘显著削弱了观众对自身健康可控性的信念，并增强了他们对健康偶然结果的信念。观众对医疗服务提供者控制健康的信念受到他们对电影描绘的现实性感知的影响。角色认同的影响在男性和女性观众之间有所不同。将结合沉浸分析作为一种媒体效果的理论方法来讨论这些结果。
