OBJECTIVES
The Difficulties in Emotion Regulation Scale (DERS) is increasingly used in adolescents. This study is the first to examine the factor structure, measurement, and structural invariance across age, reliability, and validity of the original 36-item and 16-item version of the DERS in adolescents with eating disorders.
METHODS
Several models were examined using confirmatory factor analysis. Measurement and structural invariance were studied across age groups, and Omega, Omega Hierarchical, and criterion validity were examined.
RESULTS
A bifactor model, with five subscales, showed acceptable fit in both DERS versions. Measurement and structural invariance held across age. The general factor had high reliability and accounted for a large proportion of variance in eating pathology and emotional symptoms.
CONCLUSION
The Awareness subscale had a negative effect on fit in DERS, but both DERS versions were reliable and valid measures in both younger and older adolescents with eating disorders when using only five subscales.
目的
情绪调节困难量表（DERS）在青少年中应用越来越广泛。本研究首次检验了进食障碍青少年中 DERS 原始 36 项和 16 项版本的因子结构、测量和结构不变性、信度和效度。
方法
采用验证性因子分析对几种模型进行了检验。在不同年龄组中研究了测量和结构不变性，并检验了 ω、ω 分层和效标效度。
结果
双因素模型，包括五个分量表，在两个 DERS 版本中均具有可接受的拟合度。测量和结构不变性在各年龄组中保持一致。一般因素具有较高的信度，并且可以解释进食障碍和情绪症状的大部分变异。
结论
在 DERS 中，觉察分量表对拟合度有负面影响，但当仅使用五个分量表时，两种 DERS 版本对于年轻和年长的进食障碍青少年都是可靠且有效的测量工具。
