Since the primary role of psychoeducation in eating disorders is to act as a foundation for other interventions, nutritional rehabilitation should use the same therapeutic principles as psychotherapy. This paper looks at the possibility that traditional psychoeducational results can be enhanced in patients with bulimia nervosa by a new nutritional rehabilitation programme focused on psychobiological reorganization of eating behaviour as opposed to the prescription of regular eating patterns. Forty women with purging-type bulimia nervosa were enrolled for a 24-week experimental period of cognitive-behavioural psychotherapy (CBT) and were randomly and evenly divided into two groups to follow a psychobiological nutritional rehabilitation (PNR) and a traditional nutritional rehabilitation (TNR) programme respectively. The follow-up period averaged 6 months; four subjects dropped out. The baselines of both groups were comparable with regard to key features, including binge and vomiting frequency, and carbohydrate and lipid intake. Both groups improved significantly over time, though improvements in bingeing and vomiting and lipid intake were greater in the PNR group (p < 0.001), both at the end of the study and at the follow-up. This psychobiological approach to appetite and weight control may constitute a theoretical framework facilitating the application of cognitive-behavioural guidelines to both nutritional rehabilitation and psychotherapy.
由于心理教育在饮食失调中的主要作用是作为其他干预措施的基础，营养康复应采用与心理治疗相同的治疗原则。本文探讨了通过一项新的营养康复计划来增强神经性贪食症患者传统心理教育效果的可能性，该计划侧重于饮食行为的心理生物学重组，而非规定常规饮食模式。四十名患有清除型神经性贪食症的女性参加了为期24周的认知行为心理治疗（CBT）实验期，并被随机且平均分为两组，分别遵循心理生物学营养康复（PNR）和传统营养康复（TNR）计划。随访期平均为6个月；四名受试者退出。两组在关键特征方面的基线具有可比性，包括暴饮暴食和呕吐频率以及碳水化合物和脂质摄入量。随着时间的推移，两组均有显著改善，不过在研究结束时和随访时，PNR组在暴饮暴食、呕吐和脂质摄入方面的改善更大（p < 0.001）。这种对食欲和体重控制的心理生物学方法可能构成一个理论框架，便于将认知行为指导方针应用于营养康复和心理治疗。
