The Distress Tolerance Scale (DTS) (Corstorphine, Mountford, Tomlinson, Waller, & Meyer, 2007) measures the tendency to use cognitive and behavioural strategies to manage the experience of positive and negative affect. This paper aimed to explore the factor structure of the DTS, particularly in relation to avoidance of affect. Participants were 227 female university students (non-clinical sample) and 257 clients seeking treatment for an eating disorder (clinical sample). Confirmatory factor analysis was used to test two previously proposed factor structures of the DTS in the non-clinical sample. Both of these models were found to be a poor fit to the data. Subsequently, nine items measuring avoidance of affect were analysed using exploratory factor analysis in the non-clinical sample. Three factors of avoidance of affect were identified (Behavioural Avoidance of Positive Affect, Behavioural Avoidance of Negative Affect, and Cognitive Avoidance of Affect). Confirmatory factor analysis supported this avoidance of affect model in the clinical sample. Significant correlations were observed between avoidance of affect subscales and eating psychopathology in both samples. Results suggest that the avoidance of positive emotion may be an important factor in eating disorders. It is recommended that future studies broaden their investigation of the role of emotion in eating disorders to include both negative and positive emotion.
痛苦耐受力量表（DTS）（Corstorphine、Mountford、Tomlinson、Waller 和 Meyer，2007）用于衡量使用认知和行为策略来管理积极和消极情绪体验的倾向。本文旨在探索 DTS 的因子结构，特别是与回避情绪的关系。参与者为 227 名女性大学生（非临床样本）和 257 名寻求饮食障碍治疗的患者（临床样本）。在非临床样本中，使用验证性因子分析检验了 DTS 的两种先前提出的因子结构。这两种模型都与数据拟合不佳。随后，在非临床样本中，使用探索性因子分析对测量回避情绪的 9 个项目进行了分析。确定了回避情绪的三个因素（积极情绪的行为回避、消极情绪的行为回避和情绪的认知回避）。临床样本的验证性因子分析支持这种回避情绪模型。在两个样本中，回避情绪亚量表与饮食病理学之间存在显著相关性。结果表明，回避积极情绪可能是饮食障碍的一个重要因素。建议未来的研究扩大对情绪在饮食障碍中的作用的调查，包括消极和积极情绪。
