调查前瞻性地预测行为和认知进食障碍症状持续与非持续的基线因素，因为对维持因素的了解有限，可以为设计更有效的进食障碍治疗提供信息。来自4个预防试验的数据被结合在一起，这些试验针对有身体形象问题的年轻女性(N=1952；男性19.7岁，SD 5.7)，并收集了超过1年的行为和认知症状的访谈评估数据，以解决这一目标。暴饮暴食的严重程度预示着暴饮暴食的持久性。更大的节食、暴饮暴食的频率和严重程度、体重/体型高估以及感觉肥胖预示着补偿性行为的持久性。较低的BMI预示较低的BMI持续性。较瘦的理想内化、身体不满、节食、负面情绪、暴饮暴食的频率、暴饮暴食的严重程度、补偿行为、体重/身材高估、对肥胖或体重增加的恐惧以及感觉肥胖会预测体重/身材高估的持久性。更瘦的理想内化、节食、补偿性行为、体重/体型高估、对肥胖或体重增加的恐惧、以及感觉肥胖预示着对肥胖或体重增加的持续恐惧。结果支持了几种现有饮食障碍治疗的干预目标，并确定了治疗中没有普遍针对的新的维持因素(例如，负面影响)。结果还表明，进食障碍的某些特征预示着症状的持续性。
Investigate baseline factors that prospectively predict persistence versus non-persistence of behavioral and cognitive eating disorder symptoms because knowledge of maintenance factors, which is limited, could inform the design of more effective eating disorder treatments. Data from 4 prevention trials that targeted young women with body image concerns (N = 1952; M age 19.7, SD 5.7) and collected interview-assessed data on behavioral and cognitive symptoms over 1-year follow-up were combined to address this aim. Greater binge eating severity predicted binge eating persistence. Greater dieting, binge eating frequency and severity, weight/shape overvaluation, and feeling fat predicted compensatory behavior persistence. Lower BMI predicted low BMI persistence. Greater thin-ideal internalization, body dissatisfaction, dieting, negative affect, binge eating frequency, binge eating severity, compensatory behaviors, weight/shape overvaluation, fear of fatness or weight gain, and feeling fat predicted weight/shape overvaluation persistence. Greater thin-ideal internalization, dieting, compensatory behaviors, weight/shape overvaluation, fear of fatness or weight gain, and feeling fat predicted persistence of fear of fatness or weight gain. Results provide support for intervention targets of several extant eating disorder treatments and identified novel maintenance factors not commonly targeted in treatments (e.g., negative affect). Results also imply that certain features of eating disorders predict symptom persistence.
