Perfectionism is characterized by setting high standards and striving for achievement, sometimes at the expense of social relationships and wellbeing. Despite sometimes being viewed as a positive feature by others, people with perfectionism tend to be overly concerned about their performance and how they are being perceived by people around them. This tends to create inflexible standards, cognitive biases, and performance-related behaviors that maintain a belief that self-worth is linked to accomplishments. Cognitive behavior therapy has been shown to be a viable treatment for perfectionism, both in terms of reducing levels of perfectionism and improving psychiatric symptoms. Furthermore, a number of recent studies indicate that it can be successfully delivered via the Internet, both with regular support and guidance on demand from a therapist. In the present study protocol, a clinical trial for perfectionism is described and outlined. In total, 128 participants will be recruited and randomized to either a treatment that has already been demonstrated to have many benefits, Internet-based Cognitive Behavior Therapy for perfectionism (iCBT-P), or an active comparison condition, Internet-based Unified Protocol (iUP), targeting the emotions underlying depression and anxiety disorders. The results will be investigated with regard to self-reported outcomes of perfectionism, psychiatric symptoms, self-compassion, and quality of life, at post-treatment and at six- and 12-month follow-up. Both iCBT-P and iUP are expected to have a positive impact, but the difference between the two conditions in terms of their specific effects and adherence are currently unknown and will be explored. The clinical trial is believed to lead to a better understanding of how perfectionism can be treated and the specificity of different treatments.

完美主义的特点是设定高标准并追求成就，有时以牺牲社会关系和福祉为代价。尽管有时被他人视为一个积极的特征，但拥有完美主义的人往往过分关注自己的表现以及周围的人如何看待他们。这往往会产生僵化的标准，认知偏见以及与绩效相关的行为，这些行为使人相信自我价值与成就息息相关。从降低完美主义水平和改善精神病症状的角度来看，认知行为疗法已被证明是一种完美主义的可行疗法。此外，最近的一些研究表明，在治疗师的定期支持和指导下，它可以通过互联网成功交付。在本研究方案中，描述和概述了完美主义的临床试验。总共将招募128名参与者并将其随机分配到一种已被证明具有很多益处的疗法，基于互联网的完美主义认知行为疗法（iCBT-P）或一种积极的比较条件，基于互联网的统一协议（ iUP），针对抑郁症和焦虑症的潜在情感。在治疗后以及六个月和十二个月的随访中，将就自我完善报告，精神病症状，自我同情和生活质量的自我报告结果进行调查。预计iCBT-P和iUP都将产生积极影响，但是目前尚不了解并且将探索这两种条件之间在其特定效果和依从性方面的差异。
