Anorexia nervosa (AN) and obsessive-compulsive disorder (OCD) are highly comorbid. However, the factors that account for this comorbidity are poorly understood. We examined the core dimensions of AN and OCD and psychological and personality factors shared by both disorders.
In path analyses (N = 732 women with either current AN or recovered from AN), we examined which factors were uniquely and independently associated with the core dimensions of AN and OCD. We also examined recovery from AN as a moderator.
When individuals with AN reported greater concern over mistakes, they endorsed more severity in both AN and OCD core dimensions. These unique associations existed above and beyond all other transdiagnostic personality and psychological factors and regardless of AN recovery status.
Concern over mistakes partially accounts for severity in the core dimensions of both AN and OCD. Concern over mistakes may represent an important target in the aetiology of AN and OCD.
神经性厌食症（AN）和强迫症（OCD）的共病率很高。然而，导致这种共病的因素还不太清楚。我们研究了 AN 和 OCD 的核心维度以及这两种疾病共有的心理和人格因素。
在路径分析中（N=732 名患有当前 AN 或已从 AN 中恢复的女性），我们研究了哪些因素与 AN 和 OCD 的核心维度有独特的、独立的关联。我们还研究了 AN 的恢复情况作为一个调节因素。
当患有 AN 的个体报告对错误的担忧更多时，他们在 AN 和 OCD 的核心维度上都报告了更严重的程度。这些独特的关联存在于所有其他跨诊断人格和心理因素之上，并且与 AN 的恢复状况无关。
对错误的担忧部分解释了 AN 和 OCD 的核心维度的严重程度。对错误的担忧可能代表了 AN 和 OCD 发病机制中的一个重要目标。
