ABSTRACT

Little is known about psychological interventions for stress-induced Exhaustion disorder (ED), and there is a need for more research to improve the outcomes obtained in treatments. The present study examines predictors of improvement, including sub-group responses, in a large sample of ED patients receiving a Multimodal intervention (MMI) based on Cognitive Behavior Therapy (N = 915). In step one, available variables were explored separately as predictors of improvement in ED symptoms. In step two, sub-groups were explored through Latent Class Analysis to reduce the heterogeneity observed in the larger group and to investigate whether combining the variables from step one predicted symptom improvement. Younger age, no previous sick leave due to ED, and scoring high on anxiety, depression, insomnia, perfectionism, and treatment credibility emerged as separate predictors of improvement. In the sub-group analyses, a sub-group including participants who were single and had a lower income showed less improvement. Overall, people with ED participating in MMI report symptom improvement regardless of characteristics before treatment. However, the present findings do have the potential to inform future treatments for ED, as they highlight perfectionism as a predictor of improvement and the importance of assessing treatment credibility during treatment.

摘要

对于压力诱发的疲惫障碍 (ED) 的心理干预知之甚少，需要进行更多研究来改善治疗效果。本研究在接受基于认知行为疗法（N）的多模式干预（MMI）的大样本 ED 患者中检查了改善的预测因素，包括亚组反应。 = 915）。第一步，单独探讨可用变量作为 ED 症状改善的预测因子。在第二步中，通过潜在类别分析探索亚组，以减少在较大组中观察到的异质性，并研究组合第一步中的变量是否可以预测症状改善。年龄较小、之前没有因勃起功能障碍请病假、在焦虑、抑郁、失眠、完美主义和治疗可信度方面得分较高，这些都是改善的独立预测因素。在亚组分析中，包括单身且收入较低的参与者在内的亚组显示改善较小。总体而言，参与 MMI 的 ED 患者报告症状有所改善，无论治疗前的特征如何。然而，目前的研究结果确实有可能为未来的 ED 治疗提供信息，
