目标：情绪调节困难量表（DERS）是一种广泛使用的主观情绪能力自我报告测量方法，由一个突出的临床情绪调节模型定义（Gratz和Roemer，2004）。虽然DERS经常用于治疗和研究环境中的成人情绪（即，焦虑、情绪、强迫症或创伤相关）障碍，其心理测量特性在这一人群中没有得到很好的表征。帕拉;&帕拉;方法：我们在一个大样本（N = 427）中检查了DERS和三种流行的简短形式（DERS-16; DERS-18;和DERS-SF）的心理测量学特性，这些样本是患有一种或多种DSM-5情绪障碍的寻求治疗的成年人。结果：对于原来的DERS，内部一致性强，除意识的所有分量表。一个双因素结构，包括一个一般的情绪失调因素和五个不相关的具体因素，对应于原来的DERS分量表（不包括意识）提供了最佳的拟合。一系列结构方程模型（SEM）证明了一般因素和几个特定因素对解释并发临床严重程度的独特增量贡献。一般因素和一个特定因素（目标）还前瞻性地预测了一部分有出院数据的参与者（n = 202）接受门诊认知行为治疗（CBT）自然疗程后的治疗结果。具体来说，更严重的情绪失调在摄入量预测更好的CBT反应，而更严重的障碍，目标导向的活动时，痛苦预测更差的CBT反应。所有三个简短的形式都显示了一个强大的双因子结构和良好的内部一致性和收敛效度相对维斯原始的措施，尽管在增量效用略有减少（1-3%的方差解释临床严重程度）。帕拉：在排除意识项目的情况下，DERS具有良好的内部一致性和稳健的双因子潜在结构。一般因素和几个特定因素增量和前瞻性预测临床严重程度和治疗结果，这表明DERS可能在寻求治疗的成人情绪障碍中具有临床和预测效用。需要进一步的研究，以建立在这个人口的收敛和判别效度。对于许多一般临床和研究目的，使用简短的DERS代替完整的DERS可能就足够了，特别是当受试者负担是一个问题时。
Objective: The Difficulties in Emotion Regulation Scale (DERS) is a widely used self-report measure of subjective emotion ability, as defined by a prominent clinically derived model of emotion regulation (Gratz and Roemer, 2004). Although the DERS is often used in treatment and research settings for adults with emotional (i.e., anxiety, mood, obsessive-compulsive, or trauma-related) disorders, its psychometric properties are not well-characterized in this population.& para;& para;Method: We examined the psychometric properties of the DERS and three popular short forms (DERS-16; DERS-18; and DERS-SF) in a large (N = 427) sample of treatment-seeking adults with one or more DSM-5 emotional disorders.& para;& para;Results: For the original DERS, internal consistency was strong for all subscales except Awareness. A bifactor structure consisting of one general emotion dysregulation factor and five uncorrelated specific factors corresponding to the original DERS subscales (excluding Awareness) provided the best fit. A series of structural equation models (SEMs) demonstrated unique incremental contributions of the general factor and several specific factors to explaining concurrent clinical severity. The general factor and one specific factor (Goals) also prospectively predicted treatment outcome following a naturalistic course of outpatient cognitive-behavioral therapy (CBT) in a subset of participants (n = 202) for whom discharge data were available. Specifically, more severe emotion dysregulation at intake predicted better CBT response, while more severe impairment in goal-directed activity when distressed predicted worse CBT response. All three short forms showed a robust bifactor structure and good internal consistency and convergent validity vis-a-vis the original measure, albeit with a slight decrement in incremental utility (1-3% less variance explained in clinical severity).& para;& para;Conclusion: With the Awareness items excluded, the DERS showed good internal consistency and a robust bifactor latent structure. The general factor and several specific factors incrementally and prospectively predicted clinical severity and treatment outcome, which suggests that the DERS may have clinical and predictive utility in treatment-seeking adults with emotional disorders. Additional research is needed to establish convergent and discriminant validity in this population. The use of a short form in lieu of the full DERS may be sufficient for many general clinical and research purposes, particularly when participant burden is a concern.
