Anorexia nervosa (AN) is a disorder characterized by rigid and restrictive eating behaviors, resulting in significantly low body weight. While specialized behavioral intensive treatment programs can reliably support individuals with AN to normalize eating and weight control behaviors and achieve weight restoration, prognostic factors predicting relapse following treatment are unclear. We examined whether changes in (i) normative eating self-efficacy, (ii) body image self-efficacy, (iii) drive for thinness, and (iv) body dissatisfaction from inpatient admission to six-month follow-up were associated with weight restoration status at program discharge and at six-month follow-up. The sample comprised 146 participants with AN admitted to a meal-based inpatient-partial hospitalization program. Participants completed questionnaires at inpatient admission and six months following program discharge. Additionally, at follow-up, participants reported the frequency of engaging in normalized eating behaviors since discharge (e.g. eating with others and preparing a balanced meal). The majority (73.3%) of participants attained a BMI > 19 at discharge and 59.6% were weight restored at six-month follow-up. Change in normative eating self-efficacy was significantly associated with weight restoration at follow-up, whereas change in body image self-efficacy, drive for thinness, and body dissatisfaction were not. For each one unit increase in normative eating self-efficacy, patients were 4.65 times more likely to be weight restored at follow-up (p = .002). Additionally, individuals reporting a higher frequency of normalized eating behaviors at follow-up were more likely to be weight restored. Normative eating self-efficacy and normalized eating behaviors may represent vital treatment targets for relapse prevention interventions for this high-risk population.

神经性厌食症 (AN) 是一种以严格和限制性的饮食行为为特征的疾病，导致体重显着降低。虽然专门的行为强化治疗计划可以可靠地支持 AN 患者使饮食和体重控制行为正常化并实现体重恢复，但预测治疗后复发的预后因素尚不清楚。我们检查了 (i) 规范饮食自我效能感、(ii) 身体形象自我效能感、(iii) 追求瘦身和 (iv) 从住院到 6 个月随访期间的身体不满意的变化是否与体重相关计划出院和六个月随访时的恢复状态。样本包括 146 名 AN 参与者，他们参加了以膳食为基础的住院部分住院计划。参与者在入院时和计划出院后六个月完成问卷。此外，在随访中，参与者报告了自出院后进行正常饮食行为的频率（例如与他人一起吃饭和准备均衡的膳食）。大多数 (73.3%) 参与者在出院时达到 BMI > 19，59.6% 在六个月的随访中体重恢复。规范饮食自我效能感的变化与随访时体重恢复显着相关，而身体形象自我效能感、追求瘦身和身体不满意的变化则与之无关。正常饮食自我效能每增加 1 个单位，患者在随访时体重恢复的可能性增加 4.65 倍。参与者报告了自出院后进行正常饮食行为的频率（例如与他人一起吃饭和准备均衡的膳食）。大多数 (73.3%) 参与者在出院时达到 BMI > 19，59.6% 在六个月的随访中体重恢复。规范饮食自我效能感的变化与随访时体重恢复显着相关，而身体形象自我效能感、追求瘦身和身体不满意的变化则与之无关。正常饮食自我效能每增加 1 个单位，患者在随访时体重恢复的可能性增加 4.65 倍。参与者报告了自出院后进行正常饮食行为的频率（例如与他人一起吃饭和准备均衡的膳食）。大多数 (73.3%) 参与者在出院时达到 BMI > 19，59.6% 在六个月的随访中体重恢复。规范饮食自我效能感的变化与随访时体重恢复显着相关，而身体形象自我效能感、追求瘦身和身体不满意的变化则与之无关。正常饮食自我效能每增加 1 个单位，患者在随访时体重恢复的可能性增加 4.65 倍。6% 的人在六个月的随访中体重恢复。规范饮食自我效能感的变化与随访时体重恢复显着相关，而身体形象自我效能感、追求瘦身和身体不满意的变化则与之无关。正常饮食自我效能每增加 1 个单位，患者在随访时体重恢复的可能性增加 4.65 倍。6% 的人在六个月的随访中体重恢复。规范饮食自我效能感的变化与随访时体重恢复显着相关，而身体形象自我效能感、追求瘦身和身体不满意的变化则与之无关。正常饮食自我效能每增加 1 个单位，患者在随访时体重恢复的可能性增加 4.65 倍。p  = .002）。此外，在随访中报告更高频率的正常饮食行为的个体更有可能恢复体重。规范的饮食自我效能和正常化的饮食行为可能代表了这一高危人群复发预防干预措施的重要治疗目标。
