ObjectiveEven with recruitment efforts for racial and ethnic minorities in dementia research, there is still underrepresentation in these communities. Targeting barriers and facilitators to research participation, we developed and tested a culturally tailored communication approach tailored for Hispanics.MethodsAn iterative process informed by input from the minority advisory board of an Alzheimer's Disease Research Center, developed 2 brief health communication videos, featuring Hispanic actors/Spanish language sub-titles. The experimental video (POWER) focused on barriers, facilitators, and readiness to participate in dementia research. The control video focused on education only. A randomized prospective survey compared POWER vs. control. While race or ethnicity were not inclusion criteria for enrollment, we oversampled Hispanic and non-white communities. We examined change pre- vs. post-video on dementia knowledge, cumulative barriers, and facilitators to research participation, as well as change in research readiness measured by the Transtheoretical behavior change model.ResultsThe analyzable sample ( = 184) had a mean age of 40.0 (SD = 13.2) years, 57.4% ( = 105) female, 47.2% ( = 85) non-white, 21.2% ( = 39) Hispanic, with 88 individuals randomized to POWER and 96 to control. Unadjusted evaluation of change from pre- vs. post-video showed significant improvements in dementia knowledge, research facilitators and research barriers (all s < .001) but no significant difference between POWER vs. controls. Adjusted for age, gender, race, ethnicity and education, only change in dementia knowledge remained significantly improved for the group as a whole, with no significant difference between POWER vs. controls. In the entire sample, Hispanics had significantly more improvement in research readiness ( = .217, = .003). Exploratory analysis of positive change predictors in those randomized to POWER and to control suggests Hispanics in POWER may be at a disadvantage with respect to dementia knowledge ( = -.248, = .02) and research facilitators ( = -.342, = .001).ConclusionsHealth communications can improve dementia knowledge across diverse communities.
尽管在痴呆症研究中努力招募少数族裔参与，但这些群体的代表性仍然不足。针对研究参与的障碍和促进因素，我们开发并测试了一种专门为西班牙裔量身定制的文化适应性沟通方法。
在阿尔茨海默病研究中心少数族裔咨询委员会的意见指导下，通过反复迭代过程，制作了2个简短的健康沟通视频，由西班牙裔演员出演并配有西班牙语字幕。实验视频（POWER）聚焦于参与痴呆症研究的障碍、促进因素以及准备情况。对照视频仅聚焦于教育内容。一项随机前瞻性调查对POWER视频和对照视频进行了比较。虽然种族或族裔不是纳入标准，但我们对西班牙裔和非白人社区进行了过度抽样。我们研究了视频前后痴呆症知识、累积障碍以及研究参与促进因素的变化，以及通过跨理论行为改变模型衡量的研究准备情况的变化。
可分析样本（n = 184）的平均年龄为40.0（标准差 = 13.2）岁，57.4%（n = 105）为女性，47.2%（n = 85）为非白人，21.2%（n = 39）为西班牙裔，88人随机分配到POWER组，96人分配到对照组。视频前后变化的未调整评估显示，痴呆症知识、研究促进因素和研究障碍均有显著改善（所有p值 <.001），但POWER组与对照组之间无显著差异。在对年龄、性别、种族、族裔和教育进行调整后，仅痴呆症知识的变化在整个组中仍有显著改善，POWER组与对照组之间无显著差异。在整个样本中，西班牙裔在研究准备情况方面有显著更多的改善（p =.217，r =.003）。对随机分配到POWER组和对照组的人群中积极变化预测因素的探索性分析表明，POWER组中的西班牙裔在痴呆症知识（p = -.248，r =.02）和研究促进因素（p = -.342，r =.001）方面可能处于劣势。
健康沟通可以提高不同社区对痴呆症的认识。
