Previous research suggests that there is a bidirectional relationship between incidental affect (i.e., how people feel in day-to-day life) and physical activity behavior. However, many inconsistencies exist in the body of work due to the lag interval between affect and physical activity measurements.
Using a novel continuous-time analysis paradigm, we examined the temporal specificity underlying the dynamic relationship between positive and negative incidental affective states and moderate-to-vigorous physical activity (MVPA).
A community sample of adults (n = 126, Mage = 27.71, 51.6% Male) completed a 14-day ambulatory assessment protocol measuring momentary positive and negative incidental affect six times a day while wearing a physical activity monitor (Fitbit). Hierarchical Bayesian continuous-time structural equation modeling was used to elucidate the underlying dynamics of the relationship between incidental affective states and MVPA.
Based on the continuous-time cross-effects, positive and negative incidental affect predicted subsequent MVPA. Furthermore, engaging in MVPA predicted subsequent positive and negative incidental affect. Incidental affective states had a greater relative influence on predicting subsequent MVPA compared to the reciprocal relationship. Analysis of the discrete-time coefficients suggests that cross-lagged effects increase as the time interval between measurements increase, peaking at about 8 h between measurement occasions before beginning to dissipate.
The results provide support for a recursive relationship between incidental affective states and MVPA, which is particularly strong at 7-9 hr time intervals. Future research designs should consider these medium-term dynamics, for both theory development and intervention.
先前的研究表明，偶然情绪（即人们在日常生活中的感受）与身体活动行为之间存在双向关系。然而，由于情绪和身体活动测量之间的滞后间隔，许多工作中的不一致性仍然存在。
使用一种新颖的连续时间分析范式，我们研究了积极和消极偶然情绪状态与中等到剧烈身体活动（MVPA）之间动态关系的时间特异性。
一个社区样本的成年人（n=126，Mage=27.71，51.6%为男性）完成了一项为期 14 天的活动监测协议，在佩戴身体活动监测器（Fitbit）的情况下，每天六次测量瞬间积极和消极的偶然情绪。分层贝叶斯连续时间结构方程模型用于阐明偶然情绪状态和 MVPA 之间关系的潜在动态。
基于连续时间交叉效应，积极和消极的偶然情绪预测了随后的 MVPA。此外，进行 MVPA 预测了随后的积极和消极的偶然情绪。与互惠关系相比，偶然情绪状态对预测随后的 MVPA 具有更大的相对影响。离散时间系数的分析表明，交叉滞后效应随着测量间隔的增加而增加，在测量间隔约为 8 小时时达到峰值，然后开始消散。
结果为偶然情绪状态和 MVPA 之间的递归关系提供了支持，在 7-9 小时的时间间隔内，这种关系特别强烈。未来的研究设计应考虑这些中期动态，以进行理论发展和干预。
