Public health researchers face important challenges if they wish to include measures of hearing or cognitive ability in risk communication studies. We sought validity evidence for self-report measures of hearing and cognitive ability by comparing those measures to performance-based measures and risk information recall. We measured hearing ability (with audiologist-assisted assessment and self report), cognitive ability (with an established performance task and self report), and reactions to direct-to-consumer prescription drug promotion with adults 18 and older ( = 1064) in North Carolina, USA, in 2017. We found moderate correspondence between self-reported hearing loss and audiologist-assessed hearing loss. Both measures also showed a small negative association with recall of presented risk information. Cognitive ability results suggested less substantial correspondence between self report and performance task and the measures differed in predicting risk recall. Our results suggested a moderately efficient measure for hearing ability for research on risk information exposure and retention, and yet also suggested the need for caution regarding future use of self-reported cognitive ability as a substitute for a performance-based measure.
如果公共卫生研究人员希望在风险沟通研究中纳入听力或认知能力的测量指标,他们将面临重大挑战。我们通过将听力和认知能力的自我报告测量指标与基于表现的测量指标以及风险信息回忆进行比较,来寻求这些自我报告测量指标的效度证据。2017年,我们在美国北卡罗来纳州对18岁及以上的成年人( = 1064)进行了听力能力(通过听力学家辅助评估和自我报告)、认知能力(通过既定的表现任务和自我报告)以及对直接面向消费者的处方药促销活动的反应的测量。我们发现自我报告的听力损失与听力学家评估的听力损失之间存在中等程度的一致性。这两种测量指标还都与所呈现风险信息的回忆呈小的负相关。认知能力的结果表明,自我报告与表现任务之间的一致性不太显著,并且这两种测量指标在预测风险回忆方面存在差异。我们的结果表明,对于风险信息暴露和留存研究而言,听力能力的自我报告测量指标具有一定的有效性,但同时也表明在未来将自我报告的认知能力作为基于表现的测量指标的替代方法时需要谨慎。
