The aim of this study was to explore the factor structure, scale characteristics and convergent validity of a German version of the Eating Disorder Symptom Impact Scale (EDSIS). A total of 335 parents of adolescents and young adults with anorexia nervosa in inpatient or outpatient treatment completed the 24-item German translation of the EDSIS and other measures of caregiving burden and psychological distress. We tested a 4 vs. 6-factor model of the EDSIS using confirmatory factor analyses. The 6-factor model treating items as ordinal variables showed the best fit to the data (CFI = 0.949, RMSEA = 0.064). Strong invariance of this model was shown between the sample of mothers and fathers. Internal consistencies of the EDSIS scales were in the acceptable-to-good range. Bottom effects were observed for the 'Binge-Purge-Impacts' subscale only. Mothers had significantly higher EDSIS scores compared to fathers. The EDSIS total score and most of the subscores showed substantial positive correlations with caregivers' psychological distress, level of depression, anxiety and expressed emotion as well as negative associations with the level of perceived caregiving skills. The German version of the EDSIS is a useful tool to assess caregiving burden in mothers and fathers of patients with anorexia nervosa.
本研究旨在探讨德文版饮食失调症状影响量表（EDSIS）的因子结构、量表特征和收敛效度。共有335名接受住院或门诊治疗的神经性厌食症青少年和青年的父母完成了24项德文版EDSIS以及其他照顾负担和心理困扰测量。我们使用验证性因子分析测试了EDSIS的4因子模型与6因子模型。将项目视为有序变量的6因子模型对数据的拟合度最佳（CFI = 0.949，RMSEA = 0.064）。该模型在母亲和父亲样本之间表现出强不变性。EDSIS各量表的内部一致性处于可接受至良好范围。仅在“暴饮暴食-清除影响”子量表中观察到底部效应。母亲的EDSIS得分显著高于父亲。EDSIS总分和大多数子得分与照顾者的心理困扰、抑郁水平、焦虑和表达情绪呈显著正相关，与感知照顾技能水平呈负相关。德文版EDSIS是评估神经性厌食症患者父母照顾负担的有用工具。
