This study aimed to explore the manifestation of body dysmorphic disorder symptoms in a sample of people with eating disorders and to investigate possible associations between body dysmorphia and alexithymia. Forty patients currently seeking treatment for an eating disorder completed a battery of six measures assessing alexithymia, mood, eating behaviours, weight-related body image, body dysmorphia and non-weight related body image. Significant moderate positive correlations (Pearson's r) between selected variables were found, suggesting that participants with high levels of dysmorphic concern (imagined ugliness) have more difficulty with the affective elements of alexithymia, that is, identifying and describing feelings. When depression, eating attitudes, and weight-related body image concerns were controlled for, significant moderate positive correlations between this alexithymia factor and dysmorphic concerns remained present. An independent-samples t-test between eating-disordered participants with and without symptoms of body dysmorphic disorder (BDD) revealed significant group differences in difficulties identifying feelings. This pattern of results was replicated when the groups were identified on the basis of dysmorphic concerns, as opposed to BDD symptoms. This study highlights the associations between alexithymia and body dysmorphia that have not previously been demonstrated.
本研究旨在探讨饮食障碍患者中体象障碍症状的表现，并调查体象障碍与述情障碍之间的可能关联。四十名正在接受饮食障碍治疗的患者完成了一套六项评估述情障碍、情绪、饮食行为、与体重相关的身体意象、体象障碍和与体重无关的身体意象的测量工具。Pearson 相关分析显示，一些变量之间存在显著的中度正相关，这表明具有较高体象障碍关注（想象中的丑陋）的参与者在述情障碍的情感成分方面（即识别和描述感受）存在更多困难。当控制抑郁、饮食态度和与体重相关的身体意象问题时，这个述情障碍因素与体象障碍关注之间仍存在显著的中度正相关。在有无体象障碍障碍（BDD）症状的饮食障碍患者之间进行独立样本 t 检验显示，在识别感受方面存在显著的组间差异。当根据体象障碍关注而不是 BDD 症状来识别组时，这种结果模式得到了复制。本研究强调了以前未曾证明的述情障碍与体象障碍之间的关联。
