Study recruitment and retention of older adults in research studies is a major challenge. Enhancing understanding of individual differences in motivations to participate, and predictors of motivators, can serve the dual aims of facilitating the recruitment and retention of older adults, benefiting study validity, economy, and power.
Older adults (N = 472) past and potential participants were surveyed about motivations to participate in research, demographic, and individual difference measures (e.g., health status, cognitive difficulties). Latent class and clustering analyses explored motivation typologies, followed by regression models predicting individual motivators and typologies.
Older adults endorsed a diversity of research motivations, some of which could be predicted by individual difference measures (e.g., older participants were more motivated by the desire to learn new technology, participants without a college education were more motivated by financial compensation, and participants with greater self-reported cognitive problems were more likely to participate to gain cognitive benefit). Clustering analysis revealed 4 motivation typologies: brain health advocates, research helpers, fun seekers, and multiple motivation enthusiasts. Cognitive difficulties, age, employment status, and previous participation predicted membership in these categories.
Results provide an understanding of different participant motivations beyond differences between younger and older adults and begin to identify different classes of older adults motivated to participate in research studies. Results can provide guidance for targeted recruitment and retention strategies based on individual differences in stated or predicted motivations.
研究招募和保留老年人群体参与研究是一个重大挑战。增强对参与动机的个体差异的理解,以及对动机预测因素的理解,可以同时实现促进老年人群体的招募和保留、提高研究有效性、经济性和效能这两个目标。
过去和潜在的老年参与者(N=472)接受了关于参与研究的动机、人口统计学和个体差异措施(例如健康状况、认知困难)的调查。潜在类别和聚类分析探索了动机类型,然后是预测个体动机和类型的回归模型。
老年参与者表达了对研究的多种动机,其中一些可以通过个体差异措施来预测(例如,年龄较大的参与者更倾向于出于学习新技术的愿望,没有大学学历的参与者更倾向于获得经济补偿,而自我报告认知问题较多的参与者更有可能出于获得认知益处的目的参与研究)。聚类分析揭示了 4 种动机类型:大脑健康倡导者、研究助手、寻求乐趣者和多种动机热衷者。认知困难、年龄、就业状况和先前的参与情况预测了这些类别的成员身份。
结果提供了对除了年轻和老年参与者之间的差异之外的不同参与者动机的理解,并开始确定不同类别的老年人群体参与研究的动机。结果可以为基于既定或预测动机的个体差异提供有针对性的招募和保留策略提供指导。
