The purpose of the present study was to evaluate reducing perfectionism as a potential treatment target for individuals with Bulimia Nervosa (BN).
Forty-eight individuals meeting DSM-IV criteria for BN or eating disorder - not otherwise specified with binge eating [objective or subjective] or purging at least once per week were recruited. Participants were randomly assigned to receive 8 sessions of manual-based guided self-help (GSH) over a 6-week period that was focused on either cognitive behaviour therapy (CBT) for perfectionism, CBT for BN, or a placebo. Individuals were assessed at baseline, pre-treatment, post-treatment and at six-month follow-up on 12 outcome variables, including diagnostic criteria and psychological variables.
There was no significant change in any of the outcome variables over a 6-week no-treatment period but at post-treatment and 6-month follow-up there were significant main effects of time for 10 and 8 outcome variables respectively, suggesting that all groups reported significant reductions in bulimic symptomatology and related psychopathology at post-treatment and follow-up.
These findings show potential for the use of novel interventions in GSH for BN.
本研究旨在评估降低完美主义作为神经性贪食症（BN）患者潜在治疗靶点的效果。
招募了48名符合DSM-IV标准的BN患者或未另行明确诊断的饮食失调患者，这些患者存在[客观或主观]暴饮暴食或每周至少一次清除行为。参与者被随机分配，在6周内接受8次基于手册的自助指导（GSH），内容分别聚焦于针对完美主义的认知行为疗法（CBT）、针对BN的CBT或安慰剂。在基线、治疗前、治疗后以及6个月随访时，对包括诊断标准和心理变量在内的12个结局变量进行评估。
在为期6周的无治疗期内，任何结局变量均无显著变化，但在治疗后和6个月随访时，分别有10个和8个结局变量出现显著的时间主效应，这表明所有组在治疗后和随访时暴食症状及相关精神病理学症状均有显著减轻。
这些发现表明在GSH中使用新型干预措施治疗BN具有潜力。
