Alexithymia, or deficits in emotion recognition, and metacognitive capacity have been noted both in psychosis and eating disorders and potentially linked to psychopathology. This study sought to compare levels of impairments in these phenomena and their associations with psychopathology in groups with eating disorders and psychosis. Participants with diagnoses of a schizophrenia spectrum disorder (SSD; n = 53), anorexia (n = 40), or bulimia (n = 40) were recruited from outpatient clinics. Alexithymia was measured with the Toronto Alexithymia Scale; emotion recognition, with the Ekman Faces Test; and metacognition, with the Metacognitive Assessment Scale-Abbreviated. Psychopathology was measured with the Eating Attitudes Test, Body Image Questionnaire, and Positive and Negative Syndrome Scale. Results indicated that the SSD group had significantly poorer metacognitive function than either eating disorder group. Metacognition was related to body image in the anorexia group and a range of different forms of general psychopathology in the bulimia group. Alexithymia was related to eating disorder behaviors in the bulimia group.
述情障碍，或情绪识别缺陷，以及元认知能力，在精神病和饮食失调中都有被注意到，并且可能与精神病理学有关。本研究旨在比较有饮食失调和精神病的群体中这些现象的受损程度及其与精神病理学的关联。从门诊诊所招募了被诊断为精神分裂症谱系障碍（SSD；n=53）、厌食症（n=40）或贪食症（n=40）的参与者。使用多伦多述情障碍量表测量述情障碍；使用伊克曼面部测试测量情绪识别；使用元认知评估量表-简式测量元认知。使用饮食态度测试、身体意象问卷和阳性与阴性综合征量表测量精神病理学。结果表明，SSD 组的元认知功能明显比任何一个饮食失调组都差。元认知与厌食症组的身体意象有关，与贪食症组的一系列不同形式的一般精神病理学有关。述情障碍与贪食症组的饮食失调行为有关。
