We examined the influence of depression and anxiety on executive function in individuals with a DSM-IV diagnosis of anorexia nervosa-restricting type, anorexia nervosa-binge-eating/purging type, bulimia nervosa, or eating disorder not otherwise specified.
We assessed 106 women after their inpatient treatment in an eating disorders program. All participants were nutritionally stable at the time of testing.
Thirty percent of the total sample showed impaired performance on one or more tests of executive function. No differences in executive function were observed among diagnostic groups. Anxiety scores accounted for significant variance in performance for all groups.
Executive function deficits were found in a minority of our sample, with significant variance in performance accounted for by self-reported anxiety. State anxiety appears to contribute to diminished executive function in women with eating disorders.
我们研究了抑郁和焦虑对符合 DSM-IV 诊断标准的神经性厌食症限制型、神经性贪食症/暴食-清除型、神经性贪食症或未特定的饮食障碍患者执行功能的影响。
我们在饮食障碍项目的住院治疗后评估了 106 名女性。所有参与者在测试时营养状况稳定。
总样本中有 30%的人在一项或多项执行功能测试中表现出受损。在诊断组之间没有观察到执行功能的差异。焦虑评分占所有组表现的显著差异。
在我们的样本中发现了执行功能缺陷，表现出显著的差异，由自我报告的焦虑引起。状态焦虑似乎对饮食障碍女性的执行功能下降有影响。
