To evaluate the long-term efficacy of three psychotherapies for anorexia nervosa.
Participants were women with broadly defined anorexia nervosa who had participated in a RCT comparing specialized psychotherapies (cognitive behavior therapy, CBT, and interpersonal psychotherapy, IPT) with a control condition (specialist supportive clinical management, SSCM), and attended long-term follow-up assessment (mean 6.7 years ± 1.2).
Forty three of the original sample of 56 women participated in long-term follow-up assessment (77%). No significant differences were found on any pre-selected primary, secondary or tertiary outcome measures among the three psychotherapies at long-term follow-up assessment. Significantly different patterns of recovery were identified for the psychotherapies across time on the primary global outcome measure. Although SSCM was associated with a more rapid response than IPT, by follow-up all three treatments were indistinguishable.
Potential implications for the timing of interventions to improve treatment response in anorexia nervosa are critically examined.
评估三种心理疗法治疗神经性厌食症的长期疗效。
参与者为患有广义神经性厌食症的女性，她们参加了一项 RCT，比较了专门的心理疗法（认知行为疗法，CBT 和人际心理疗法，IPT）与对照条件（专家支持性临床管理，SSCM），并参加了长期随访评估（平均 6.7 年±1.2 年）。
56 名女性中的原始样本中有 43 名（77%）参加了长期随访评估。在长期随访评估中，三种心理疗法在任何预先选择的主要、次要或三级结局测量上均无显著差异。在主要的整体结局测量上，不同的心理疗法在时间上的恢复模式存在显著差异。尽管 SSCM 与 IPT 相比，反应更快，但随访时所有三种治疗方法都没有区别。
对改善神经性厌食症治疗反应的干预时机的潜在影响进行了批判性审查。
