神经性厌食症(AN)是一种严重的精神障碍，在青春期发病，被发现很难治疗。确定预测长期结果的变量可能有助于制定更好的治疗策略。由于身体形象扭曲和体重增加是诊断和治疗AN的核心要素，本研究在76名女性青少年AN患者样本中调查了知觉性身体形象扭曲，其定义是评估自己感知的身体尺寸与实际身体尺寸的准确性，以及住院治疗期间的总体重和早期体重增加，作为预测长期结果的指标。长期结果是通过使用Morgan-Russell结果评估表的生理、心理和心理社会调整，以及治疗大约3年后仅由月经和/或体重指数组成的物理结果来定义的。知觉体像扭曲和早期体重增加可以预测长期结果(解释方差为13.3%)，但不能单独预测身体结果。这项研究首次证明了知觉的身体形象扭曲与青少年神经性厌食症的长期结局之间的联系，并强调了早期足够的体重增加的重要性。
Anorexia nervosa (AN), a severe mental disorder with an onset during adolescence, has been found to be difficult to treat. Identifying variables that predict long-term outcome may help to develop better treatment strategies. Since body image distortion and weight gain are central elements of diagnosis and treatment of AN, the current study investigated perceptual body image distortion, defined as the accuracy of evaluating one's own perceived body size in relation to the actual body size, as well as total and early weight gain during inpatient treatment as predictors for long-term outcome in a sample of 76 female adolescent AN patients. Long-term outcome was defined by physical, psychological and psychosocial adjustment using the Morgan-Russell outcome assessment schedule as well as by the mere physical outcome consisting of menses and/or BMI approximately 3 years after treatment. Perceptual body image distortion and early weight gain predicted long-term outcome (explained variance 13.3 %), but not the physical outcome alone. This study provides first evidence for an association of perceptual body image distortion with long-term outcome of adolescent anorexia nervosa and underlines the importance of sufficient early weight gain.
