评估行为干预对罕见结果的有效性是一项挑战。其中一个主题是中风准备，定义为增加中风症状识别和拨打911的行为意图的干预。目前的中风准备中间结果测量集中在书面小插曲或开放式问题，并已被证明不能很好地反映实际行为。鉴于中风识别和行动需要听觉和视觉处理，视频小插曲可以改善目前的措施。本文讨论了在社区参与式研究伙伴关系中创建新的卒中准备视频小插曲中间结果测量的方法。共拍摄了20个视频片段，其中13个是明确的（中风或非中风），由中风专家确定，并在社区参与者之间进行了测试的歧视。在14个社区受访者中发现了可接受的可靠性，高满意度和文化相关性。以社区为基础的参与性方法在制作视频短片中间成果方面是有效的。未来的项目应考虑在拍摄所有视频短片之前获得专家和社区的反馈，以提高可用短片的比例。本研究建立了内容效度和初步信度，但其信度和结构效度仍有待进一步研究。
Evaluating the efficacy of behavioral interventions for rare outcomes is a challenge. One such topic is stroke preparedness, defined as inteventions to increase stroke symptom recognition and behavioral intent to call 911. Current stroke preparedness intermediate outcome measures are centered on written vignettes or open ended questions and have been shown to poorly reflect actual behavior. Given that stroke identification and action requires aural and visual processing, video vignettes may improve upon current measures. This article discusses an approach for creating a novel stroke preparedness video vignette intermediate outcome measure within a community based participatory research partnership. A total of 20 video vignettes were filmed of which 13 were unambiguous (stroke or not stroke) as determined by stroke experts and had test discrimination among community participants. Acceptable reliability, high satisfaction and cultural relevance were found among the 14 community respondents. A community based participatory approach was effective in creating a video vignette intermediate outcome. Future projects should consider obtaining expert and community feedback prior to filming all the video vignettes to improve the proportion of vignettes that are usable. While content validity and preliminary reliability were established, future studies are needed to confirm the reliability and establish construct validity.
