背景资料：本实验研究测试暴露于视频叙事成功的症状缓解与医用大麻（MC）的态度，信念和意图相关的娱乐性cannabinuse.Methods的影响：患者的视频证言后，发现在现存的媒体报道。通过在线调查公司招募的以色列参与者（N = 396）被随机分配观看包含MC相关信息的叙事或非叙事视频。视频内容被进一步操纵的基础上是否有一个污名化的疾病或没有，以及是否归因于他的疾病的责任是内部或external.Results：暴露于病人的证词间接增加了积极的态度，信念和意图有关的娱乐性大麻的使用，通过改变态度，信念和意图MC。此外，暴露于叙述中，病人被认为不应该为感染他的疾病而受到指责，（外部归因）与对MC的更积极的态度、信念和意图相关，这一因素与娱乐性大麻使用相关的更积极的态度、信念和意图显著相关。这些结果表明，MC的叙事新闻媒体报道可能会影响公众对娱乐性大麻的态度。由于这种媒体报道仍然司空见惯，因此必须审查这种报道对公众对娱乐性大麻的看法的潜在溢出效应。大麻预防方案应解决媒体报道在塑造公众舆论方面的作用，并解决医疗和娱乐性大麻使用之间的区别。
Background: This experimental study tests effects of exposure to video narratives about successful symptom relief with Medical Cannabis (MC) on attitudes, beliefs, and intentions related to recreational cannabis use.Methods: Patient video testimonials were modeled after those found in extant media coverage. Israeli participants (N = 396) recruited through an online survey company were randomly assigned to view a narrative or a non-narrative video containing equivalent information about MC. Video content was further manipulated based on whether the protagonist had a stigmatized disease or not, and whether attribution of responsibility for his disease was internal or external.Results: Exposure to patient testimonials indirectly increased positive attitudes, beliefs and intentions related to recreational cannabis use through changing attitudes, beliefs and intentions related to MC. Furthermore, exposure to narratives in which the patient was presented as not to blame for contracting his illness (external attribution) was associated with more positive attitudes, beliefs and intentions toward MC, a factor that was significantly associated with more positive attitudes, beliefs and intentions related to recreational cannabis use.Conclusions: These results suggest that narrative news media coverage of MC may influence public attitudes toward recreational cannabis. Because such media stories continue to be commonplace, it is important to examine potential spillover effects of this coverage on public perceptions of recreational cannabis. Cannabis prevention programs should address the role of media coverage in shaping public opinion and address the distinction between medical and recreational cannabis use.
