OBJECTIVE
The current study examined the effectiveness of individual (IND) versus group (GRP) therapy for patients with bulimia nervosa (BN), using a manual of sequenced treatment with cognitive-behavioral therapy (CBT) followed by interpersonal psychotherapy (IPT).
METHOD
Eighty-six participants with BN were matched and randomized to 23 sessions of IND or GRP. Participants were measured pretreatment and posttreatment and at 1-year and 2.5-year follow-ups using both intent-to-treat and completer samples.
RESULTS
The intent-to-treat analysis revealed that the percentage of participants recovered and remitted was equivalent between IND and GRP. Significant group differences were found between completers on binge eating and compensatory behavior with greater improvement for IND. On most measures, effect sizes were larger for IND at 1-year follow-up.
CONCLUSION
Sequencing CBT and IPT worked well in both IND and GRP formats. We found few outcome differences between IND as opposed to GRP.
目的
本研究使用认知行为疗法（CBT）随后进行人际心理治疗（IPT）的顺序治疗手册，检验个体治疗（IND）与团体治疗（GRP）对神经性贪食症（BN）患者的有效性。
方法
86名BN参与者被匹配并随机分配接受23节IND或GRP治疗。使用意向性分析样本和完成治疗样本，在治疗前、治疗后以及1年和2.5年随访时对参与者进行测量。
结果
意向性分析显示，IND组和GRP组中康复和缓解的参与者百分比相当。在完成治疗者中，发现IND组在暴饮暴食和代偿行为方面有显著的组间差异，IND组改善更大。在大多数测量指标上，1年随访时IND组的效应量更大。
结论
CBT和IPT的顺序治疗在IND和GRP两种形式中均效果良好。我们发现IND组与GRP组之间的结果差异很小。
