Other Specified Feeding and Eating Disorders (OSFED) are characterized by less frequent symptoms or symptoms that do not meet full criteria for another eating disorder. Despite its high prevalence, limited research has examined differences in severity and treatment outcome among patients with OSFED compared to threshold EDs [Anorexia Nervosa (AN), Bulimia Nervosa (BN), and Binge Eating Disorder (BED)]. The purpose of the current study was to examine differences in clinical presentation and treatment outcome between a heterogenous group of patients with OSFED or threshold EDs.
Patients with threshold EDs ( = 42, = 50, BED = 14) or OSFED ( = 66) presenting for eating disorder treatment completed self-report questionnaires at intake and discharge to assess eating disorder symptoms, depression symptoms, impairment, and self-esteem.
At intake, OSFED patients showed lower eating concerns compared to patients with BN, but similar levels compared to AN and BED. The OSFED group showed higher restraint symptoms compared to BED, and similar restraint to AN and BN. Global symptoms as well as shape and weight concerns were similar between OSFED and threshold ED groups. There were no differences between diagnostic groups in self-esteem, depression scores, or symptom change from intake to discharge.
Our findings suggest that individuals with OSFED showed largely similar ED psychopathology and similar decreases in symptoms across treatment as individuals diagnosed with threshold EDs. Taken together, findings challenge the idea that OSFED is less severe and more resistant to treatment than threshold EDs.
其他特定的喂养和进食障碍（OSFED）的特征是症状出现频率较低，或症状不符合其他进食障碍的完整标准。尽管其患病率很高，但与临界进食障碍（神经性厌食症（AN）、神经性贪食症（BN）和暴饮暴食症（BED））相比，针对OSFED患者的严重程度和治疗结果差异的研究有限。本研究的目的是检查OSFED患者或临界进食障碍患者的异质性群体之间在临床表现和治疗结果上的差异。
前来接受进食障碍治疗的临界进食障碍患者（AN = 42，BN = 50，BED = 14）或OSFED患者（n = 66）在入院和出院时完成自我报告问卷，以评估进食障碍症状、抑郁症状、功能损害和自尊。
入院时，与BN患者相比，OSFED患者的进食问题较少，但与AN和BED患者的水平相似。与BED患者相比，OSFED组的克制症状更高，与AN和BN患者的克制症状相似。OSFED组和临界进食障碍组在整体症状以及体型和体重问题方面相似。在自尊、抑郁评分或从入院到出院的症状变化方面，诊断组之间没有差异。
我们的研究结果表明，与被诊断为临界进食障碍的个体相比，OSFED个体在很大程度上表现出相似的进食障碍精神病理学，并且在整个治疗过程中症状减少程度相似。综上所述，研究结果挑战了OSFED比临界进食障碍症状较轻且对治疗更具抗性的观点。
