Difficulties with emotion regulation is considered an important maintaining factor of disordered eating. One of the most commonly used measures of this construct is the Difficulties in Emotion Regulation Scale (DERS). The aim of this study was to explore the factor structure of this measure in young females and to examine its reliability and validity with respect to disordered eating.
Females aged 17-25 years (M age = 19.6 years, N = 486) were examined in the analyses. Confirmatory factor analyses were conducted followed by regression analyses examining the DERS subscales as predictors of eating disorder severity and disordered eating behaviors.
The original 6-factor 36-item model did not fit well and analyses indicated a 6-factor 30-item solution was a more suitable fit for our population. Validity and reliability of the 30-item solution were found to be acceptable. Regression analyses also indicated the 36- and 30-item models were able to adequately predict eating disorder severity and disordered eating behaviors with the "Awareness" and "Goals" subscales being predictors of the former, and the "Impulsivity" subscale being a significant predictor of the latter.
The overall findings suggest that an abbreviated version of the DERS might be more appropriate than the original version with young females and that this measure exhibits stronger relationships with eating disorder severity and disordered eating behaviors than the longer version. Further examinations of the psychometric properties of the DERS with clinical populations are indicated.
情绪调节困难被认为是饮食失调的一个重要维持因素。该结构最常用的测量方法之一是情绪调节困难量表(DERS)。本研究旨在探讨该测量方法在年轻女性中的结构,并考察其在饮食失调方面的信度和效度。
对年龄在 17-25 岁的女性(M 年龄=19.6 岁,N=486)进行了分析。进行了验证性因子分析,然后进行回归分析,考察 DERS 分量表作为饮食障碍严重程度和饮食失调行为的预测指标。
最初的 6 因素 36 项模型拟合不佳,分析表明 6 因素 30 项模型更适合我们的人群。30 项模型的有效性和可靠性被认为是可以接受的。回归分析还表明,36 项和 30 项模型能够充分预测饮食障碍严重程度和饮食失调行为,其中“意识”和“目标”分量表是前者的预测指标,“冲动”分量表是后者的显著预测指标。
总体研究结果表明,与年轻女性相比,DERS 的简化版本可能更为合适,并且该测量方法与饮食障碍严重程度和饮食失调行为的关系比原始版本更为密切。需要进一步研究该量表在临床人群中的心理测量特性。
