ABSTRACT

Physical activity (PA) has been linked to cognitive functioning and mental health in older adulthood. Multiple subjective (i.e., self-report) and objective measures (e.g., pedometer) have been used to assess PA, however their agreement varies across studies. This pilot study examined cognitive predictors of the agreement between subjective and objectively measured PA. A total of 30 community-dwelling older adults completed a neuropsychological battery, as well as a measure of subjective PA and wore a wristwatch-based pedometer for 30 days to assess objective PA. Greater discrepancy between subjective and objective PA was correlated with poorer executive functioning (r = −.44, p = .02), and this remained true in regression models after controlling for age and education (b = .-54, p = .01). Older adults with lower executive functioning may be more likely to inaccurately report time spent engaging in PA. Future studies should explore whether this relationship holds in larger samples.

体力活动（PA）与老年人的认知功能和心理健康有关。多种主观（即自我报告）和客观测量（例如计步器）已被用于评估 PA，但它们的一致性在不同研究中有所不同。这项试点研究考察了主观和客观测量的 PA 之间一致性的认知预测因素。共有 30 名社区居住的老年人完成了神经心理学电池测试以及主观 PA 测量，并佩戴手表计步器 30 天来评估客观 PA。主观和客观 PA 之间的较大差异与较差的执行功能相关 (r = −.44, p = .02)，并且在控制年龄和教育程度后的回归模型中仍然如此 (b = .-54, p = .01 ）。执行功能较低的老年人可能更可能不准确地报告参与 PA 的时间。未来的研究应该探讨这种关系在更大的样本中是否成立。
