神经性直食症的特点是痴迷于吃“纯净”或“健康”的食物。尽管出现了新的兴趣，但到目前为止，关于矫形术的研究还很少发表。这项研究调查了404名本科生的现象学、相关和相关的矫形障碍。一组自我报告问卷评估了矫形症症状、相关的功能障碍、饮食紊乱、完美主义、强迫症状、外表焦虑、对负面评价的恐惧、焦虑和抑郁症状。总体而言，35.4%的参与者支持正畸症状的增加，主要关注的是与饮食违规相关的负罪感，以及在以期望的方式进食时感受到控制。矫形症症状与相关的损害变量、完美主义、饮食紊乱、外表焦虑和强迫症状显示出小到中等的相关性。所有变量(抑郁症状除外)在正畸症状升高和未升高的个体之间的平均差异被观察到。总而言之，这项研究表明，目前的方法(具有显著的局限性)显示出相对较高的正性食欲症状频率，并显示出与心理症状学相当温和的相关性。
Orthorexia nervosa is characterized by an obsession with eating "pure" or "healthy" foods. Despite emergent interest, few studies have been published about orthorexia to date. This study examined the phenomenology, correlates, and associated impairment of orthorexia in 404 undergraduate students. A battery of self-report questionnaires assessed orthorexia symptoms, related functional impairment, disordered eating, perfectionism, obsessive-compulsive symptoms, appearance anxiety, fear of negative evaluation, anxiety, and depressive symptoms. In total, 35.4% of participants endorsed elevated orthorexia symptoms, with primary concerns related to guilt associated with dietary transgressions and experiencing control when eating in a desired manner. Orthorexia symptoms demonstrated small to medium correlations with associated impairment variables, perfectionism, disordered eating, appearance anxiety, and obsessive-compulsive symptoms. Mean differences were observed across all variables (except depressive symptoms) between individuals elevated and not elevated on orthorexia symptoms. Collectively, this study suggests a relatively high frequency of orthorexia symptoms using current methods (which have significant limitations) and demonstrate fairly modest associations with psychological symptomology.
