Abstract

Ecological momentary assessment (EMA) is a methodological tool that can provide novel insights into the prediction and modeling of physical behavior; however, EMA has not been used to study physical activity (PA) or sedentary behavior (SB) among racial minority older adults. This study aimed to determine the feasibility and validity of an EMA protocol to assess racial minority older adults’ PA and SB. For 8 days, older adults (n = 91; 89% African American; 70% earning <$20,000/year) received six randomly prompted, smartphone-based EMA questionnaires per day and wore an activPAL monitor to measure PA and SB. The PA and SB were also self-reported through EMA. Participants were compliant with the EMA protocol on 92.4% of occasions. Participants were more likely to miss an EMA prompt in the afternoon compared to morning and on weekend days compared to weekdays. Participants were less likely to miss an EMA prompt when engaged in more device-based SB in the 30 min around the prompt. When participants self-reported PA, they engaged in less device-based PA in the 15 min after compared to the 15 min before the EMA prompt, suggesting possible reactance or disruption of PA. EMA-reported PA and SB were positively associated with device-based PA and SB in the 30 min around the EMA prompt, supporting criterion validity. Overall, the assessment of low-income, African American older adults’ PA and SB through EMA is feasible and valid, though physical behaviors may influence compliance and prompting may create reactivity.
利用生态瞬时评价评价低收入非裔美国老年人身体活动和久坐行为的可行性和有效性
生态瞬时评估(EMA)是一种方法论工具,可以为物理行为的预测和建模提供新颖的见解;然而,EMA尚未用于研究少数种族老年人的身体活动(PA)或久坐行为(SB)。本研究旨在确定EMA方案评估少数民族老年人PA和SB的可行性和有效性。为期8天,老年人(n = 91;89%是非裔美国人;70%收入< 20,000美元/年)每天接受6份随机提示的基于智能手机的EMA问卷,并佩戴活动pal监视器来测量PA和SB。PA和SB也通过EMA自我报告。参与者在92.4%的情况下符合EMA协议。与上午相比,参与者更有可能在下午错过EMA提示,与工作日相比,周末更有可能错过EMA提示。当参与者在提示前后的30分钟内从事更多基于设备的SB时,他们不太可能错过EMA提示。当参与者自我报告PA时,与EMA提示前15分钟相比,他们在EMA提示后15分钟内从事较少的基于设备的PA,这表明可能存在PA的抗拒或中断。EMA提示前后30分钟内,EMA报告的PA和SB与基于器械的PA和SB呈正相关,支持标准有效性。总体而言,通过EMA评估低收入、非裔美国老年人的PA和SB是可行和有效的,尽管身体行为可能会影响依从性,提示可能会产生反应。
