To examine the potential factor structure of the Eating Disorder Diagnostic Scale (EDDS) in a sample of individuals with bipolar disorder.
Exploratory common factor analyses were conducted in a sample of 1031 people with bipolar disorder as defined by the Structured Clinical Interview for DSM-IV-TR.
Approximately 27% of participants had a comorbid eating disorder. Exploratory factor analysis yielded a 3 factor solution (i.e., shape/weight concerns; binge eating behaviors, compensatory behavior).
The 3-factor solution of the EDDS in a bipolar disorder sample is consistent with major eating disorder symptom domains. Future research is necessary to replicate these findings in eating disorder samples with diverse comorbid psychopathology.
在双相情感障碍患者样本中，考察饮食障碍诊断量表（EDDS）的潜在因素结构。
对 1031 名经 DSM-IV-TR 定式临床访谈诊断为双相情感障碍的患者进行探索性共同因素分析。
约 27%的参与者患有共患饮食障碍。探索性因素分析得出了 3 个因素的解决方案（即体型/体重问题；暴食行为、补偿行为）。
在双相情感障碍样本中，EDDS 的 3 因素解决方案与主要饮食障碍症状领域一致。未来的研究有必要在具有不同共病精神病理学的饮食障碍样本中复制这些发现。
