OBJECTIVE Improvement in emotion regulation is a proposed transdiagnostic mechanism of change. However, treatment research is limited by disorder-specific investigations that assess a narrow number of emotion regulation strategies. Moreover, most assess pre-to-post-treatment change without examining short-term changes throughout psychotherapy that might influence treatment response. METHOD To address these gaps, this study uses daily diary methodology to examine trajectories of change in use of six emotion regulation strategies during partial hospitalization psychiatric treatment. Treatment was rooted in cognitive behavioral principles and included skills adapted from empirically supported cognitive behavioral therapy (CBT) and dialectical behavior therapy (DBT) manuals. Participants were adults (N = 364; Mage = 34.6 years; 60% female; 85% non-Hispanic White) with various profiles of mood, anxiety, and obsessive-compulsive disorders who completed symptom measures at baseline and discharge and daily measures of emotion regulation. RESULTS In the first 7 treatment days, patients increased use of engagement strategies (reappraisal, acceptance) and decreased use of disengagement (expressive suppression) and cognitive perseveration (experiential avoidance, rumination) strategies. Day-to-day trajectories found that decreased use of experiential avoidance predicted next-day changes in distraction and suppression use. In predicting treatment outcomes, steeper rates of decreased suppression use predicted reductions in anxiety, depression, and general psychopathology symptoms; similar patterns were observed for decreased rumination and experiential avoidance use and increased reappraisal use. CONCLUSION Results add to a growing literature on the value of intentional, constructive engagement with emotional experiences as a mechanism of psychological health.

心理治疗期间情绪调节如何变化？对跨诊断部分住院计划中的成年人进行每日日记研究。

目的 情绪调节的改善是一种拟议的跨诊断变化机制。然而，治疗研究受到特定疾病研究的限制，这些研究评估了少数情绪调节策略。此外，大多数人评估治疗前后的变化，而不检查整个心理治疗过程中可能影响治疗反应的短期变化。方法 为了解决这些差距，本研究使用每日日记方法来检查部分住院精神治疗期间六种情绪调节策略的使用变化轨迹。治疗植根于认知行为原则，包括根据经验支持的认知行为疗法（CBT）和辩证行为疗法（DBT）手册改编的技能。参与者是具有不同情绪、焦虑和强迫症特征的成年人（N = 364；Mage = 34.6 岁；60% 女性；85% 非西班牙裔白人），他们完成了基线和出院时的症状测量以及每日情绪测量规定。结果 在治疗的前 7 天，患者增加了参与策略（重新评估、接受）的使用，减少了脱离策略（表达抑制）和认知坚持（体验性回避、沉思）策略的使用。日常轨迹发现，体验性回避的使用减少预示着第二天分心和抑制使用的变化。在预测治疗结果时，抑制使用减少率的增加预示着焦虑、抑郁和一般精神病理学症状的减少；反刍和经验性回避的使用减少以及重新评估的使用增加也观察到了类似的模式。结论 越来越多的文献表明，有意识地、建设性地参与情感体验作为心理健康机制的价值，结果进一步丰富了这一点。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
