先前通过潜在结构模型推导基于经验的饮食失调（ED）类型的努力受到研究人群的种族和文化同质性以及对 DSM-IV ED 体征和症状作为指示变量的依赖的限制。斐济族女学生 (N = 523) 对自我报告进行了回应，评估了 ED 症状、草药泻药的使用、共病精神病理学、临床障碍、文化取向和同伴影响。在过去 28 天内赞同自我诱导呕吐或使用草药泻药的参与者 (n = 222) 被纳入潜在概况分析 (LPA)，以识别贪食症症状的独特亚组。 LPA 确定了神经性贪食症 (BN) 样类别 (n = 86)，其特征是暴食和自我催吐发生率高；草药泻药类（n = 136），主要特点是使用斐济本土草药泻药。两个 ED 类别都认可比非通便参与者更严重的饮食病理学和一般精神病理学，而草药通便类别则认可比 BN 类或非通便参与者更大的临床损害。两个 ED 班级之间的文化取向没有差异。将心理健康研究中代表性不足的研究人群纳入其中，并扩大潜在结构模型中相关体征和症状的范围，可能会增加 ED 疾病分类方案的普遍性，以涵盖更大的文化多样性。
Previous efforts to derive empirically based eating disorder (ED) typologies through latent structure modeling have been limited by ethnic and cultural homogeneity of their study populations and their reliance on DSM-IV ED signs and symptoms as indicator variables. Ethnic Fijian schoolgirls (N = 523) responded to a self-report battery assessing ED symptoms, herbal purgative use, comorbid psychopathology, clinical impairment, cultural orientation, and peer influences. Participants who endorsed self-induced vomiting or herbal purgative use in the past 28 days (n = 222) were included in a latent profile analysis (LPA) to identify unique subgroups of bulimic symptomatology. LPA identified a bulimia nervosa (BN)-like class (n = 86) characterized by high rates of binge eating and self-induced vomiting; and an herbal purgative class (n = 136) characterized primarily by the use of indigenous Fijian herbal purgatives. Both ED classes endorsed greater eating pathology and general psychopathology than non-purging participants, and the herbal purgative class endorsed greater clinical impairment than either BN-like or non-purging participants. Cultural orientation did not differ between the two ED classes. The inclusion of study populations underrepresented in mental health research and broadening the scope of relevant signs and symptoms in latent structure models may increase the generalizeability of ED nosological schemes to encompass greater cultural diversity.
