Although now there is accumulating research on the effectiveness of psychotherapy for perfectionism, this research has been based almost exclusively on self-report data. In this article, we describe analyses from the University of British Columbia Perfectionism Treatment Study assessing close other informant ratings of change in perfectionism traits and perfectionistic self-presentation. A total of 61 close other informants of patients who participated in a 10-week dynamic-relational treatment for perfectionism completed measures of patient trait and self-presentational facets of perfectionism at pretreatment, at posttreatment, and at a 4-month follow-up. In support of the effectiveness of the treatment, we found that close other measures of patients' self-oriented perfectionism, other-oriented perfectionism, and all three facets of perfectionistic self-presentation were significantly reduced at posttreatment and follow-up. Close other measures of patients' socially prescribed perfectionism did not show change over the course of treatment and follow-up. The findings are discussed in terms of the effectiveness of the dynamic-relational treatment of perfectionism and the utility of extending research by including close other measures of change in treatment-outcome research.

完美主义的动态关系小组治疗：对患者变化的知情评价。

尽管现在人们对心理疗法对完美主义的有效性进行了越来越多的研究，但该研究几乎完全基于自我报告数据。在本文中，我们描述了不列颠哥伦比亚大学完美主义治疗研究的分析，这些评估评估了完美主义特质的变化和完美主义自我表现的其他详尽信息。共有61位其他近距离知情人参加了为期10周的动态关系完美疗法治疗，他们在治疗前，治疗后和4个月的随访中完成了患者特征和自我陈述方面的测量。为了支持治疗的有效性，我们发现关闭了患者自我导向的完美主义，其他导向的完美主义，完美自我表现的所有三个方面在治疗后和随访中均显着降低。对患者社会规定的完美主义的其他衡量指标并未显示出在治疗和随访过程中的变化。讨论的结果涉及对完美主义进行动态关系处理的有效性，以及通过在治疗结果研究中包括其他接近的变化度量来扩展研究的实用性。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。讨论的结果涉及对完美主义进行动态关系处理的有效性，以及通过在治疗结果研究中包括其他接近的变化度量来扩展研究的实用性。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。讨论的结果涉及对完美主义进行动态关系处理的有效性，以及通过在治疗结果研究中包括其他接近的变化度量来扩展研究的实用性。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。
