The aim of this study was to estimate prevalence rate of alexithymia and eating disorder (ED) as well as to explore the relationships between alexithymia and eating behavior, self esteem, and body esteem in non-clinical college women. A total of 313 Japanese college women were asked to make entries of age, height, and body weight, and to answer the full items in the Japanese version of the Toronto Alexithymia Scale (TAS-20), Eating Attitude Test (EAT-26), Rosenberg Self Esteem Scale (RSES), and Body Esteem Scale (BES). The frequency of alexithymics who scored 61 points or more of the TAS-20 was 28.7%, and the frequency of students with potential ED who scored 20 points or more of the EAT-26 was 8.7%. The prevalence of potential ED in the alexithymics (14.0%) was significantly higher than that in the non-alexithymics (6.5%). The mean values of the RSES and BES scores were significantly different between the alexithymic and non-alexithymic groups. The TAS-20 scores were unrelated to the age and body mass index, but were significantly correlated to the EAT-26 (total score (r = 0.12, p = 0.04), bulimia and food preoccupation (r = 0.14, p = 0.01)), the RSES (r = -0.44, p < 0.001), and BES (total score (r = -0.22, p < 0.001), appearance (r = -0.23, p < 0.001), and weight (r = -012, p = 0.04)). These results suggest that, in non-clinical college women, alexithymia is a common psychological characteristic that is strongly correlated with self esteem and body esteem and that may influence eating behavior.
本研究旨在估计述情障碍和饮食失调（ED）的患病率，并探讨非临床在校女大学生中述情障碍与饮食行为、自尊及身体自尊之间的关系。共有313名日本在校女大学生被要求填写年龄、身高和体重，并回答日文版多伦多述情障碍量表（TAS-20）、饮食态度测试（EAT-26）、罗森伯格自尊量表（RSES）和身体自尊量表（BES）的全部项目。TAS-20得分61分及以上的述情障碍者的频率为28.7%，EAT-26得分20分及以上的潜在饮食失调学生的频率为8.7%。述情障碍者中潜在饮食失调的患病率（14.0%）显著高于非述情障碍者（6.5%）。述情障碍组和非述情障碍组的RSES和BES得分均值存在显著差异。TAS-20得分与年龄和体重指数无关，但与EAT-26（总分（r = 0.12，p = 0.04）、暴食和食物先占观念（r = 0.14，p = 0.01））、RSES（r = -0.44，p < 0.001）以及BES（总分（r = -0.22，p < 0.001）、外貌（r = -0.23，p < 0.001）和体重（r = -0.12，p = 0.04））显著相关。这些结果表明，在非临床在校女大学生中，述情障碍是一种常见的心理特征，与自尊和身体自尊密切相关，且可能影响饮食行为。
