Current evidence indicates treatment for adults with anorexia nervosa (AN) requires improvement given recovery rates are low to moderate, and relapse rates are high. Metacognitive therapy (MCT) is an effective treatment for anxiety and depressive disorders. This study evaluates if MCT can be successfully modified to treat AN in a naturalistic clinical setting.
Twenty-four patients with AN participated in an open trial of modified metacognitive therapy (MCT-AN). Twelve of the 24 patients (50%) completed treatment. MCT was modified to include components specific to eating disorders. The MCT-AN was delivered by clinical psychologists who had undertaken training in MCT in a specialist outpatient service. Group and single participant data analyses were undertaken on those who completed treatment.
As well as statistically significant differences from pre- to posttreatment in the group data there were also clinically significant improvements at the individual patient level for eating disorder and depressive symptoms, as well as weight. The mean number of therapy sessions was 18.
These findings indicate that MCT-AN may be a promising intervention in the treatment of AN, warranting further investigation.
Treatment for anorexia nervosa in adults requires improvement. Research indicates that Metacognitive therapy (MCT) is an effective treatment for anxiety and depression and may be applicable to the eating disorders. This small open trial suggests that MCT can be modified successfully to treat patients with anorexia nervosa (AN). The results are preliminary and require further research to provide more evidence on the effectiveness of this treatment for AN.
现有证据表明，成人厌食症（AN）的治疗需要改进，因为恢复率较低且中等，复发率较高。元认知疗法（MCT）是一种有效的焦虑和抑郁障碍治疗方法。本研究评估了 MCT 是否可以成功修改为在自然临床环境中治疗 AN。
24 名 AN 患者参加了 MCT 改良（MCT-AN）的开放试验。24 名患者中有 12 名（50%）完成了治疗。MCT 进行了修改，纳入了针对饮食失调的特定成分。MCT-AN 由在专门的门诊服务中接受过 MCT 培训的临床心理学家提供。对完成治疗的患者进行了组和单个参与者数据分析。
除了组数据从治疗前到治疗后的统计学显著差异外，在个体患者层面上，饮食障碍和抑郁症状以及体重也有明显的改善。平均治疗次数为 18 次。
这些发现表明，MCT-AN 可能是治疗 AN 的一种有前途的干预措施，值得进一步研究。
