目的：我们的目标是评估观察者述情障碍量表(OAS)在饮食障碍患者中的心理测量学特性，跨诊断亚组的述情障碍严重程度，以及三种述情障碍测量之间的一致性。方法：75名被诊断为进食障碍的女性完成了两份述情障碍自我报告，即20个条目的多伦多述情障碍量表(TAS-20)和Bermond-Vorst述情障碍问卷B版(BVAQ-B)，并要求亲戚或熟人使用OAS对她们进行评分。结果：OAS具有较好的区分效度和评定者间信度。患者的OAS得分高于普通人群样本的报告得分，低于门诊临床样本的得分。神经性厌食症限制性患者与神经性贪食症患者的OAS、TAS-20、BVAQ-B评分差异无统计学意义。OAS、TAS-20和BVAQ-B总分呈中度正相关，相关显著。结论：这些临床数据显示了OAS的心理测量学强度，可以合理地推荐在研究和临床实践中与TAS-20一起使用。(C)2007年，爱思唯尔公司出版。
Objectives: Our objectives were to evaluate the psychometric properties of the Observer Alexithymia Scale (OAS) in eating disorder patients, alexithymia severity across diagnostic subgroups, and correspondence among three alexithymia measures. Method: Seventy-five women, each with an eating disorder diagnosis, completed two alexithymia self-reports, the 20-item Toronto Alexithymia Scale (TAS-20) and the Bermond-Vorst Alexithymia Questionnaire-version B (BVAQ-B), and asked a relative or an acquaintance to rate them using the OAS. Results: The OAS showed acceptable discriminant validity and interrater reliability. Patients' OAS scores were higher than scores reported for people-in-general samples and lower than those for outpatient clinical samples. No statistically significant OAS, TAS-20, and BVAQ-B score differences were found between the patients with anorexia nervosa restrictive type and those with bulimia nervosa. OAS, TAS-20, and BVAQ-B total scores were moderately, positively, and significantly correlated. Conclusion: These clinical data show the psychometric strength of the OAS, which reasonably can be recommended for use with the TAS-20 in research and clinical practice.
