Perfectionism is associated with the development and maintenance of anxiety, mood, and eating disorders. Cognitive behaviour therapy (CBT) results in significant reductions in perfectionism and psychological symptoms however, the majority of studies have not examined clinical samples or impact on diagnostic status and comorbidity.
Forty participants with elevated perfectionism, of whom 80% had a range of psychological disorders, were randomised to CBT for perfectionism or waitlist control.
The treatment group reported significant large effect size reductions in perfectionism measures of personal standards and concern over mistakes (d = 1.1-1.6), dichotomous thinking (d = 1.2), and medium effect size reductions in depression (d = 0.55) and increases in quality of life (d = 0.73), which were maintained at 4 month follow-up. The participants in the treatment group were significantly less likely to present with comorbid psychological disorders at post-treatment than the control group.
The sample size was small, and there was no control condition at follow-up.
Findings lend further support for CBT for perfectionism as an efficacious transdiagnostic treatment for perfectionism and related psychopathology.
完美主义与焦虑、情绪和饮食障碍的发展和维持有关。认知行为疗法（CBT）可显著降低完美主义和心理症状，但大多数研究并未检查临床样本或对诊断状况和共病的影响。
40 名完美主义程度较高的参与者中，有 80%的人患有各种心理障碍，他们被随机分配到完美主义 CBT 组或候补名单对照组。
治疗组在个人标准和对错误的担忧（d=1.1-1.6）、二分思维（d=1.2）的完美主义测量中报告了显著的大效应量减少，抑郁（d=0.55）和生活质量（d=0.73）的中等效应量减少，这些在 4 个月的随访中得以维持。治疗组的参与者在治疗后出现共病心理障碍的可能性明显低于对照组。
样本量小，随访时无对照组。
这些发现进一步支持 CBT 作为一种有效的跨诊断治疗方法，用于治疗完美主义和相关精神病理学。
