Adults with serious mental illness engage in limited physical activity, which contributes to significant health disparities. This study explored the use of both ecological momentary assessments (EMAs) and activity trackers in adults with serious mental illness to examine the bidirectional relationship between activity and affect with multilevel modeling. Affective states were assessed up to seven times per day using EMA across 4 days. The participants (n = 20) were equipped with a waist-worn accelerometer to measure moderate to vigorous physical activity. The participants had a mean EMA compliance rate of 88.3%, and over 90% of completed EMAs were matched with 30-min windows of accelerometer wear. The participants who reported more positive affect than others had a higher probability of engaging in moderate to vigorous physical activity. Engaging in more moderate to vigorous physical activity than one's usual was associated with more negative affect. This study begins to address the effect of momentary mood on physical activity in a population of adults that is typically difficult to reach.
患有严重精神疾病的成年人身体活动有限，这导致了显著的健康差距。本研究探讨了生态瞬时评估（EMA）和活动追踪器在患有严重精神疾病的成年人中的应用，以通过多层次建模研究活动与情感之间的双向关系。在4天内，每天使用EMA对情感状态进行多达7次评估。参与者（n = 20）佩戴腰部加速度计以测量中度至剧烈的身体活动。参与者的EMA平均依从率为88.3%，超过90%的已完成EMA与加速度计佩戴的30分钟窗口相匹配。报告比其他人有更多积极情感的参与者进行中度至剧烈身体活动的可能性更高。与自己平时相比进行更多中度至剧烈身体活动与更多消极情感相关。本研究开始探讨瞬时情绪对一个通常难以接触到的成年人群体身体活动的影响。
