Background:There is considerable evidence indicating that similar aetiological and maintenance processes underlie depressive and anxious psychopathology. According to the literature, perfectionism and emotion regulation are two transdiagnostic constructs associated with symptoms of emotional disorders.Aims:This study is the first randomized controlled trial comparing the efficacy of cognitive behavioural therapy for perfectionism (CBT-P) and the unified protocol for the transdiagnostic treatment of emotional disorders (UP).Method:Seventy-five participants with a range of depressive and anxiety disorders and elevated perfectionism were randomized to three conditions: CBT-P, UP or a waitlist control (WL).Results:Repeated measures ANOVA indicated that the treatment groups reported a significantly greater pre–post reduction in the severity of symptoms of disorders, as well as a significantly greater pre–post increase in quality of life, all with moderate to large effect sizes compared with the WL group. Treatment gains were maintained at 6-month follow-up. The CBT-P group reported a significantly greater pre–post reduction in perfectionism compared with UP, and the UP group reported a significantly greater pre–post improvement in emotion regulation compared with CBT-P.Conclusions:Findings support CBT for perfectionism and regard UP as efficacious treatments for individuals with depression and anxiety disorders who also have dysfunctional perfectionism. It appears that perfectionism cannot be a serious obstacle to UP. As this is a preliminary study and has some limitations, it is recommended that further research be conducted.

专注于完美主义的 CBT 与专注于情绪调节的 CBT 对抑郁症和焦虑症以及功能失调的完美主义患者的比较：一项随机对照试验

背景：有大量证据表明，类似的病因和维持过程是抑郁和焦虑精神病理学的基础。根据文献，完美主义和情绪调节是与情绪障碍症状相关的两个跨诊断结构。目的：本研究是第一个比较完美主义认知行为疗法（CBT-P）和统一方案的随机对照试验。情绪障碍 (UP) 的跨诊断治疗。方法：75 名患有一系列抑郁和焦虑障碍以及完美主义升高的参与者被随机分配到三个条件：CBT-P、UP 或候补名单控制 (WL)。结果：重复测量 ANOVA 表明，与 WL 相比，治疗组报告的疾病症状严重程度在事前显着降低，生活质量在事后显着提高，所有这些都具有中到大的影响大小团体。在 6 个月的随访中维持治疗收益。与 UP 相比，CBT-P 组报告的完美主义事前减少显着更大，与 CBT-P 相比，UP 组报告的情绪调节事前改善显着更大。结论：研究结果支持 CBT 对完美主义并认为 UP作为抑郁症和焦虑症患者的有效治疗方法，他们也有功能失调的完美主义。看来完美主义不能成为 UP 的严重障碍。
