Posttraumatic stress symptoms (PTSS) among women experiencing intimate partner violence (IPV) are a major public health burden. Yet, there is a need to better understand how IPV and PTSS relate over time. One understudied factor that may influence the IPV-PTSS association is dysregulation stemming from positive emotions. The objective of the current study was to clarify the temporal dynamics between IPV types (psychological, physical, sexual) and PTSS as well as the influence of positive emotion dysregulation.
Participants were 145 women recruited from the community (M = 40.66, 40.7 % white) experiencing IPV and using any amount of alcohol or drugs who completed a baseline session and three daily surveys for 30 days. A multi-level dynamic structural equation modeling analysis was tested.
At the within-person level, significant cross-lagged effects were found for IPV predicting next-interval PTSS for psychological (Standardized Fixed Effect Estimate = 0.27, 95 % CI[0.02, 0.61]) and physical (Standardized Fixed Effect Estimate = 0.61, 95 % CI[0.22, 1.14]) IPV, but not sexual IPV. At the between-person level, baseline positive emotion dysregulation was significantly associated with the random cross-lagged effect for IPV and next-interval PTSS for sexual IPV (Standardized Fixed Effect Estimate = 0.29, 95 % CI[0.02, 0.52]), but not psychological or physical IPV.
Findings shed light on how IPV across types perpetuates PTSS in the daily lived experiences of women who experience IPV and use substances and underscore a significant influence of positive emotion dysregulation.
遭受亲密伴侣暴力（IPV）的女性中的创伤后应激症状（PTSS）是一项重大的公共卫生负担。然而，有必要更好地了解IPV与PTSS如何随时间相互关联。一个未得到充分研究的可能影响IPV与PTSS关联的因素是源于积极情绪的调节障碍。本研究的目的是阐明IPV类型（心理、身体、性方面）与PTSS之间的时间动态关系以及积极情绪调节障碍的影响。
研究对象为145名从社区招募的女性（M = 40.66，40.7%为白人），她们遭受IPV且使用任何量的酒精或药物，完成了一次基线评估以及为期30天的每日三次调查。进行了多层次动态结构方程模型分析。
在个体内部层面，发现心理IPV（标准化固定效应估计值 = 0.27，95%置信区间[0.02，0.61]）和身体IPV（标准化固定效应估计值 = 0.61，95%置信区间[0.22，1.14]）在预测下一时间段的PTSS方面存在显著的交叉滞后效应，但性方面的IPV不存在这种效应。在个体之间层面，基线积极情绪调节障碍与性方面IPV的IPV和下一时间段PTSS的随机交叉滞后效应显著相关（标准化固定效应估计值 = 0.29，95%置信区间[0.02，0.52]），但与心理或身体IPV无关。
研究结果揭示了不同类型的IPV如何在遭受IPV且使用药物的女性的日常生活经历中使PTSS持续存在，并强调了积极情绪调节障碍的重大影响。
