Anorexia nervosa (AN) has been suggested to be associated with abnormalities in facial emotion recognition. Most prior studies on facial emotion recognition in AN have investigated adult samples, despite the onset of AN being particularly often during adolescence. In addition, few studies have examined whether impairments in facial emotion recognition are specific to AN or might be explained by frequent comorbid conditions that are also associated with deficits in emotion recognition, such as depression. The present study addressed these gaps by investigating recognition of emotional facial expressions in adolescent girls with AN (n = 26) compared to girls with major depression (MD; n = 26) and healthy girls (HC; n = 37). Participants completed one task requiring identification of emotions (happy, sad, afraid, angry, neutral) in faces and two control tasks. Neither of the clinical groups showed impairments. The AN group was more accurate than the HC group in recognising afraid facial expressions and more accurate than the MD group in recognising happy, sad, and afraid expressions. Misclassification analyses identified subtle group differences in the types of errors made. The results suggest that the deficits in facial emotion recognition found in adult AN samples are not present in adolescent patients.
神经性厌食症 (AN) 被认为与面部情绪识别异常有关。尽管 AN 的发病通常在青春期,但大多数关于 AN 患者面部情绪识别的先前研究都调查了成年样本。此外,很少有研究研究面部情绪识别受损是否是 AN 特有的,或者是否可以通过与情绪识别缺陷相关的常见合并症来解释,例如抑郁症。本研究通过比较 AN(n = 26)、重性抑郁障碍(MD;n = 26)和健康对照(HC;n = 37)的少女,研究了情绪识别的缺陷,以填补这些空白。参与者完成了一项需要识别面部表情(快乐、悲伤、害怕、生气、中性)的任务和两项控制任务。两个临床组都没有表现出损伤。AN 组在识别害怕的面部表情方面比 HC 组更准确,在识别快乐、悲伤和害怕的表情方面比 MD 组更准确。错误分类分析确定了各组在错误类型上的细微差异。结果表明,在成年 AN 样本中发现的面部情绪识别缺陷在青少年患者中并不存在。
