不同的术语已被用来操作进食障碍的身体形象障碍。然而，这些术语及其基本结构在异质性进食障碍中预测结果的差异有效性尚不清楚。本研究在一个跨诊断的临床样本中评估了身体意象结构预测进食障碍和负性心理症状的有效性，并进行了2年的前瞻性研究。异质性进食障碍诊断的女性（n = 448）在基线、12个月和24个月随访时完成评估。横截面和交叉滞后广义线性模型研究了三种身体意象结构的影响（即，重量和形状关注、高估和不满意）对并发和后续结果的影响（即，全球饮食失调症状、暴饮暴食、净化、禁食、自尊和抑郁）。在同期分析中，专注与所有结局显著相关（p = 0.01至<0.001），高估与所有结局显著相关（p = 0.01至<0.001），暴食除外（p = 0.06），对所有结局不满意（p <0.001），净化除外（p = 0.38）。在前瞻性分析中，专注预测进食障碍检查总体（p = .003）和空腹（p < .001），高估预测暴食（p = .01），身体不满意没有预测任何结果。关注、高估和不满意与进食障碍和精神病结果有差异，表明没有一个身体意象结构可以捕捉进食障碍的临床风险。关注是最一致的同时和纵向预测，这个结构可能需要进一步关注的评估和诊断。鼓励在不同样品中进一步研究这些结构。
Diverse terminology has been used to operationalize body image disturbance in eating disorders. However, the differential validity of these terms and their underlying constructs to predict outcomes among heterogeneous eating disorders is unknown. This study evaluated the validity of body image constructs to predict eating disorder and negative psychological symptoms concurrently and prospectively over 2 years in a transdiagnostic clinical sample. Women with heterogeneous eating disorder diagnoses (n = 448) completed assessments at baseline, 12-month, and 24-month follow-up. Cross-sectional and cross-lagged generalized linear models examined effects of three body image constructs (i.e., weight and shape preoccupation, overvaluation, and dissatisfaction) on concurrent and subsequent outcomes (i.e., global eating disorder symptoms, binge eating, purging, fasting, self-esteem, and depression). In concurrent analyses, preoccupation was significantly associated with all outcomes (ps = .01 to <.001), overvaluation with all outcomes (ps = .01 to <.001) except binge eating (p = .06), and dissatisfaction with all outcomes (ps < .001) except purging (p = .38). In prospective analyses, preoccupation predicted Eating Disorder Examination global (p = .003) and fasting (p < .001), overvaluation predicted binge eating (p = .01), and body dissatisfaction did not predict any outcomes. Preoccupation, overvaluation, and dissatisfaction are differentially related to eating disorder and psychiatric outcomes, indicating that no one body image construct can capture clinical risk in eating disorders. Preoccupation was the most consistent concurrent and longitudinal predictor; this construct may warrant further attention in assessment and diagnosis. Further investigation of these constructs in diverse samples is encouraged.
