Background

High negative affect, low positive affect, and limited physical activity figure prominently in psychopathology, but little is known about the interrelatedness of affect and physical activity in emotional disorders.

Methods

We combined ecological momentary assessment data with a network approach to examine the dynamic relations among positive affect, negative affect, and smartphone-based estimates of physical activity in 34 participants with anxiety and depressive disorders over a 2-week period.

Results

In the contemporaneous networks, the positive affect nodes exhibited greater overall strength centrality than negative affect nodes. The temporal networks indicated that the negative affect node ‘sadness’ exhibited the greatest out-strength centrality. Furthermore, physical activity was unconnected to the affect nodes in either the temporal or contemporaneous networks.

Conclusions

Whereas positive affect plays a greater role in the contemporaneous experience of emotions, negative affect contributes more so to future affective states.

情绪障碍中情感和身体活动的时间和同期网络结构

背景

高消极情绪、低积极情绪和有限的身体活动在精神病理学中占显着地位，但对情绪障碍中情绪和身体活动的相互关系知之甚少。

方法

我们将生态瞬时评估数据与网络方法相结合，以检查 34 名患有焦虑症和抑郁症的参与者在 2 周内的积极情绪、消极情绪和基于智能手机的身体活动估计之间的动态关系。

结果

在同时代的网络中，积极影响节点表现出比消极影响节点更大的整体强度中心性。时间网络表明，负面影响节点“悲伤”表现出最大的外强度中心性。此外，身体活动与时间或同期网络中的影响节点无关。

结论

积极情绪在同时期的情绪体验中发挥更大的作用，而消极情绪对未来的情绪状态的贡献更大。
