Humans in the industrialized world spend a large amount of daily time in sedentary behavior. Since sedentariness negatively impacts a variety of psychophysiological outcomes, the identification of antecedents that lead to sedentary behavior is an important public health issue. In this context, mood, a central indicator for both psychological well-being and mental health, is severely understudied. To investigate whether mood dimensions influence subsequent sedentary behavior, we assessed both constructs at baseline via questionnaires and via ambulatory assessment (AA) over 5 days in 92 university employees. We continuously measured sedentary behavior using accelerometers and assessed mood repeatedly 10 times each day on smartphone diaries. We employed multiple regression analyses to analyze between-subject effects and multilevel modeling to analyze within-subject effects. Higher momentary ratings of valence (P < .05) and energetic arousal (P < .01) predicted lower amounts of subsequent sedentary behavior, whereas higher ratings of calmness (P < .01) predicted higher amounts of subsequent sedentary behavior. The context moderated the effect of energetic arousal and calmness on sedentary behavior with increased effects in the home compared to the work context. Mood significantly predicted sedentary behavior on a within-subject level but not on a between-subject level. Preliminary evidence suggests that mood regulates sedentary behavior in everyday life. Time-sensitive analyses, such as from moment to moment revealed an association between mood and sedentary behavior (within-subject), whereas analyses between different individuals revealed no associations (between-subject). These preliminary findings may inform multicomponent intervention strategies that target mood, to reduce sedentary behavior in daily life.
在工业化世界中，人类每天有大量的时间处于久坐不动的行为中。由于久坐不动会对各种心理生理结果产生负面影响，因此确定导致久坐行为的前因是一个重要的公共卫生问题。在这种情况下，情绪作为心理幸福感和心理健康的核心指标，被严重低估了。为了研究情绪维度是否会影响随后的久坐行为，我们通过问卷和 5 天的活动记录仪评估（AA）在 92 名大学员工中评估了这两个结构。我们使用加速度计连续测量久坐行为，并使用智能手机日记每天 10 次重复评估情绪。我们采用多元回归分析来分析组间效应，采用多层次模型来分析组内效应。更高的瞬间正性评价（P <.05）和精力激发评价（P <.01）预测随后的久坐行为量较低，而更高的平静评价（P <.01）预测随后的久坐行为量较高。环境调节了精力激发和平静对久坐行为的影响，在家中的影响比在工作中的影响更大。情绪在个体内水平上显著预测了久坐行为，但在个体间水平上没有预测。初步证据表明，情绪调节了日常生活中的久坐行为。从瞬间到瞬间的时间敏感分析揭示了情绪和久坐行为之间的关联（个体内），而在不同个体之间的分析则没有发现关联（个体间）。这些初步发现可能为针对情绪的多成分干预策略提供信息，以减少日常生活中的久坐行为。
