目的 确定青少年或父母自我效能感的提高是否可以预测青少年神经性厌食症 (AN) 的两种不同疗法中随后的体重增加。 方法 受试者为 121 名患有 AN 的青少年（M=14.4 岁，SD=1.6），来自一项基于家庭的治疗 (FBT) 和个体青少年集中治疗 (AFT) 的两中心随机临床试验。在基线和第 2、4、6 和 8 节中对青少年和父母的自我效能进行评估。青少年自我效能是使用通用的自我效能测量来评估的，而父母的自我效能是使用针对饮食失调恢复的特定测量来评估。在基线、第 1 至第 8 节以及治疗结束时评估体重。使用混合效应模型来评估患者和父母的自我效能感与随后体重增加之间的关系，并控制前一个时间点的体重。结果对于接受 FBT 的家庭，与接受 FBT 但父母自我效能感变化较小的家庭和接受 AFT 的家庭相比，治疗内父母自我效能感的较大增加预示着随后青少年体重增加的更大。有趣的是，青少年自我效能感并不能显着预测随后的体重增加。讨论对于接受 FBT 的青少年来说，父母自我效能感的更大增加预示着随后体重增加的显着增加，但对于接受 AFT 的青少年来说，情况并非如此。青少年自我效能感的总体水平和变化都不能显着预测任一治疗组随后的体重增加。这些发现强调了提高父母在 FBT 中的自我效能感以影响青少年体重结果的重要性。 (c) 2015 年 Wiley periodicals, Inc.（Int J Eat Disord 2015；48:883-888）
ObjectiveTo determine whether increases in adolescent or parental self-efficacy predicted subsequent weight gain in two different therapies for adolescent anorexia nervosa (AN).MethodParticipants were 121 adolescents with AN (M=14.4 years, SD=1.6), from a two-site randomized clinical trial for family-based treatment (FBT) and individual adolescent focused therapy (AFT). Both adolescent and parental self-efficacy were assessed at baseline and sessions 2, 4, 6, and 8. Adolescent self-efficacy was assessed using a generic measure of self-efficacy, while parental self-efficacy was assessed using a measure specific to the recovery of an eating disorder. Weight was assessed at baseline, sessions 1 through 8, and end of treatment. Mixed-effects models were used to evaluate the relation between patient and parent self-efficacy and subsequent weight gain, controlling for weight at the previous time point.ResultsFor families who received FBT, greater within-treatment increases in parental self-efficacy predicted greater subsequent adolescent weight gain compared to those who received FBT with lesser change in parental self-efficacy and those who received AFT. Interestingly, adolescent self-efficacy did not significantly predict subsequent weight gain.DiscussionGreater increases in parental self-efficacy predicted significantly greater subsequent weight gain for adolescents who received FBT, but the same was not true for adolescents who received AFT. Neither overall level nor change in adolescent self-efficacy significantly predicted subsequent weight gain in either treatment group. These findings emphasize the importance of increasing parental self-efficacy in FBT in order to impact adolescent weight outcomes. (c) 2015 Wiley Periodicals, Inc. (Int J Eat Disord 2015; 48:883-888)
