To test the effectiveness of theoretically driven role model video stories in improving knowledge of palliative care among a diverse sample of older adults.
We developed three 3-4 min long theoretically driven role model video stories. We then recruited cognitively intact, English-speaking adults aged 50 and older from senior centers, assisted living, and other community-based sites in the greater Los Angeles area. Using a pretest-posttest study design, we surveyed participants using the 13-item Palliative Care Knowledge Scale (PaCKS) and also asked participants about their intentions to enroll in palliative care should the need arise. Participants first completed the pretest, viewed the three videos, then completed the posttest comprised of the same set of questions.
PaCKS score improved from an average of 4.5 at baseline to 10.0 following video screening (t(126) = 12.0, p < 0.001). Intentions to enroll oneself or a family member in palliative care rose by 103% (χ2 = 7.8, p < 0.01) and 110% (χ2 = 7.5, p < 0.01), respectively. Regression analysis revealed that participants who believed the role models are real people (β = 2.6, SE = 1.2, p < 0.05) significantly predicted higher change in PaCKS score. Conversely, participants with prior knowledge of, or experience with, palliative care (β = -5.9, SE = 0.8, p < 0.001), non-whites (β = -3.6, SE = 0.9, p < 0.001), and widows (β = -2.9, SE = 1.1, p < 0.01) significantly predicted lower changes in PaCKS score.
This study suggests that theoretically driven role model video stories may be an effective strategy to improve palliative care knowledge. Role model video stories of diverse palliative care patients provide one way to mitigate health literacy barriers to palliative care knowledge.
测试理论驱动的角色模型视频故事在提高多样化老年人群对姑息治疗知识方面的有效性。
我们制作了三个 3-4 分钟长的理论驱动角色模型视频故事。然后，我们从洛杉矶地区的老年人中心、辅助生活设施和其他社区场所招募认知正常、讲英语的 50 岁及以上成年人。采用预测试-后测试研究设计，我们使用 13 项姑息治疗知识量表（PaCKS）对参与者进行调查，还询问了参与者在有需要时是否愿意参加姑息治疗。参与者首先完成预测试，观看三个视频，然后完成由相同问题组成的后测试。
PaCKS 评分从基线时的平均 4.5 分提高到视频筛查后的 10.0 分（t(126) = 12.0，p < 0.001）。自己或家人参加姑息治疗的意愿分别提高了 103%（χ2 = 7.8，p < 0.01）和 110%（χ2 = 7.5，p < 0.01）。回归分析显示，认为角色模型是真实人物的参与者（β = 2.6，SE = 1.2，p < 0.05）显著预测 PaCKS 评分变化更高。相反，具有姑息治疗先验知识或经验（β = -5.9，SE = 0.8，p < 0.001）、非白人（β = -3.6，SE = 0.9，p < 0.001）和寡妇（β = -2.9，SE = 1.1，p < 0.01）的参与者显著预测 PaCKS 评分变化较低。
本研究表明，理论驱动的角色模型视频故事可能是提高姑息治疗知识的有效策略。多样化姑息治疗患者的角色模型视频故事提供了一种减轻姑息治疗知识健康素养障碍的方法。
