The identification of transdiagnostic risk factors and processes that explain the comorbidity between depressive symptoms and eating disorder symptoms is critical. We examined the mediating role of the frustration of adolescents' psychological needs for autonomy, competence, and relatedness in the association between self-critical perfectionism, depressive symptoms and eating disorder symptoms.
A cross-sectional study (N = 248; 58% female, mean age = 14 years) and a two-wave longitudinal study (N = 608; 59% female; mean age = 16 years) were conducted.
At the level of inter-individual differences and intra-individual change, self-critical perfectionism was a robust predictor of both symptoms. After introducing need frustration as an underlying mechanism, the relation between self-critical perfectionism and the two types of symptoms, as well as the relation between the symptoms themselves, decreased.
Need frustration represents a transdiagnostic vulnerability process that helps to explain why self-critical perfectionism relates to depressive symptoms and eating disorder symptoms.
确定能够解释抑郁症状和饮食障碍症状共病的跨诊断风险因素和过程至关重要。我们研究了青少年自主性、能力和关联性心理需求受挫在自我批评性完美主义、抑郁症状和饮食障碍症状之间的关系中的中介作用。
进行了一项横断面研究（N=248；女性占 58%，平均年龄为 14 岁）和一项两波纵向研究（N=608；女性占 59%；平均年龄为 16 岁）。
在个体间差异和个体内变化水平上，自我批评性完美主义是两种症状的强有力预测因子。在引入需求受挫作为潜在机制后，自我批评性完美主义与两种症状之间的关系以及症状本身之间的关系减弱了。
需求受挫代表一种跨诊断的脆弱性过程，有助于解释为什么自我批评性完美主义与抑郁症状和饮食障碍症状有关。
