The 2 × 2 model of perfectionism (Gaudreau and Thompson in Personal Individ Diff 48:532-537, 2010) represents an important addition to the perfectionism literature, but so far has not been studied in relation with disordered eating.
Using the 2 × 2 model as analytic framework, this study examined responses from a convenience sample of 716 participants aged 19-68 years (71% female) investigating how self-oriented perfectionism (SOP) and socially prescribed perfectionism (SPP) predicted individual differences in eating disorder symptoms, additionally controlling for body mass index, gender, and age.
Results showed a significant SOP × SPP interaction indicating that the combination of high SOP and high SPP-called "mixed perfectionism"-was associated with the highest levels of eating disorder symptoms.
The findings demonstrate the utility of the 2 × 2 model of perfectionism as an analytic framework for examining perfectionism and disordered eating. Moreover, they suggest that mixed perfectionism is the most maladaptive form of perfectionism when it comes to disordered eating, such that having high levels of SPP combined with high levels of SOP represents the most maladaptive combination of perfectionism in terms of risk of eating disorder.
Level V, cross-sectional descriptive study.
完美主义的 2×2 模型（Gaudreau 和 Thompson 在《个人差异 48:532-537》，2010 年）是完美主义文献的重要补充，但迄今为止尚未与饮食失调相关研究。
本研究使用 2×2 模型作为分析框架，调查了一个由 716 名年龄在 19 至 68 岁的参与者组成的便利样本（71%为女性），调查自我导向完美主义（SOP）和社会规定的完美主义（SPP）如何预测饮食障碍症状的个体差异，此外还控制了体重指数、性别和年龄。
结果显示 SOP×SPP 交互作用显著，表明高 SOP 和高 SPP 的组合——称为“混合完美主义”——与最高水平的饮食障碍症状相关。
研究结果表明，2×2 完美主义模型作为一种分析框架，在研究完美主义和饮食失调方面具有实用性。此外，它们表明，混合完美主义是最适应不良的完美主义形式，当涉及到饮食失调时，高 SPP 与高 SOP 相结合代表了饮食障碍风险方面最适应不良的完美主义组合。
