This study examined: (1) changes in emotion regulation difficulties in underweight inpatients with anorexia nervosa (AN) following weight restoration, (2) differences in emotion regulation between AN subtypes at acute and weight-restored stages of illness.
Repeated measure analyses of variance examined changes in scores on the Difficulties in Emotion Regulation Scale (DERS; Gratz and Roemer, J Psychopathol Behav Assess, 26, 41-54, 2004) and other clinical variables in a group of inpatients with AN from hospital admission (N = 65) to weight restoration (N = 51). Correlations between BMI and DERS scores at both time points were examined. Emotion regulation difficulties were compared between individuals with AN, restricting type (AN-R) and AN, binge/purge type (AN-BP) at both time points using multivariate analysis of covariance.
All clinical variables, except for the DERS, significantly improved with weight restoration (p < .001). There were no associations between BMI and DERS prior to or after weight restoration and AN subtypes did not significantly differ in emotion regulation difficulties.
Unlike other clinical variables, emotion regulation difficulties in AN did not improve with weight restoration. In addition, both subtypes of AN appear to have similar difficulties with emotion regulation. The treatment of AN might be enhanced by focusing on improving emotion regulation abilities.
本研究探讨了：（1）神经性厌食症（AN）体重过轻的住院患者体重恢复后情绪调节困难的变化；（2）AN不同亚型在疾病急性期和体重恢复阶段情绪调节的差异。
采用重复测量方差分析，对一组AN住院患者从入院时（N = 65）到体重恢复时（N = 51）的情绪调节困难量表（DERS；Gratz和Roemer，《心理病理学与行为评估杂志》，26，41 - 54，2004）得分及其他临床变量的变化进行了研究。检验了两个时间点体重指数（BMI）与DERS得分之间的相关性。使用协方差多元分析比较了两个时间点AN限制型（AN - R）和AN暴食/清除型（AN - BP）个体之间的情绪调节困难情况。
除DERS外，所有临床变量在体重恢复后均有显著改善（p <.001）。体重恢复前后BMI与DERS之间均无关联，且AN各亚型在情绪调节困难方面无显著差异。
与其他临床变量不同，AN患者的情绪调节困难在体重恢复后并未改善。此外，AN的两种亚型在情绪调节方面似乎都有类似的困难。关注提高情绪调节能力可能会增强AN的治疗效果。
