The current study tested a psychosocial interactive model of perfectionism, self-efficacy, and weight/shape concern within a sample of women with clinically significant bulimic symptoms, examining how different dimensions of perfectionism operated in the model. Individuals with bulimia nervosa (full diagnostic criteria or subthreshold) completed measures of bulimic symptoms, multidimensional perfectionism, self-efficacy, and weight/shape concern. Among those who were actively binge eating (n=180), weight/shape concern was associated with binge eating frequency in the context of high perfectionism (either maladaptive or adaptive) and low self-efficacy. Among those who were actively vomiting (n=169), weight/shape concern was associated with vomiting frequency only in the context of high adaptive perfectionism and low self-efficacy. These findings provide support for the value of this psychosocial interactive model among actively binge eating and purging samples and for the importance of considering different dimensions of perfectionism in research and treatment related to bulimia nervosa.
本研究在有临床显著贪食症状的女性样本中测试了完美主义、自我效能感和体重/体型关注的心理社会交互模型，考察了完美主义的不同维度在该模型中的作用方式。神经性贪食症患者（符合全部诊断标准或亚阈值）完成了贪食症状、多维完美主义、自我效能感和体重/体型关注的测量。在那些有频繁暴食行为的人（n = 180）中，在高完美主义（无论是适应不良的还是适应性的）和低自我效能感的情况下，体重/体型关注与暴食频率相关。在那些有频繁催吐行为的人（n = 169）中，体重/体型关注仅在高适应性完美主义和低自我效能感的情况下与催吐频率相关。这些发现为该心理社会交互模型在频繁暴食和催吐样本中的价值提供了支持，并为在与神经性贪食症相关的研究和治疗中考虑完美主义的不同维度的重要性提供了支持。
