Half a century of theoretical accounts, case histories, and evidence implies perfectionism limits the success of psychotherapy and makes it hard for people to participate in and benefit from close relationships. Likewise, intimate relationships are crucial determinants of the success of treatment. However, the extent to which specific types of relationships explain why perfectionism leads to a poorer treatment outcome is unclear. We addressed this by, first, testing whether the perfectionism traits of self-oriented, other-oriented, and socially prescribed perfectionism hindered symptom reduction in group psychotherapy for depression and, second, assessing the mediating role of romantic love, friendships, and familial love on the effects of perfectionism traits on change in depression. Psychiatric patients (N = 156) enrolled in short-term postdischarge group cognitive-behavioral therapy for residual depression completed measures of perfectionism at pretreatment; of romantic love, friendships, and familial love at posttreatment; and of depression at pre- and posttreatment. Multilevel modeling showed that other-oriented and socially prescribed perfectionism were associated with lower posttreatment reductions in depression over treatment, and path analysis revealed that self-oriented, other-oriented, and socially prescribed perfectionism indirectly predicted lower posttreatment reductions in depression through a perceived lack of quality friendships. Results lend credence and coherence to the perfectionism social disconnection model in a clinical context and underscore the importance of taking extratherapeutic social disconnection into account when treating perfectionistic patients.

完美主义在抑郁症团体治疗中的危险性：对完美主义社会脱节模型的检验。

半个世纪的理论解释，案例历史和证据表明，完美主义限制了心理治疗的成功，并使人们难以参与并受益于亲密关系。同样，亲密关系是治疗成功的关键决定因素。然而，具体关系类型在多大程度上解释了为什么完美主义导致较差的治疗结果尚不清楚。我们首先通过测试自我导向，他人导向和社会规定的完美主义的完美主义特征是否阻碍抑郁症的团体心理治疗中症状的减轻，其次，评估浪漫爱情，友谊和家庭爱情的中介作用完美主义特征对抑郁症变化的影响。参加短期出院后小组针对残余抑郁症的认知行为疗法的精神病患者（N = 156）在治疗前完成了完美主义的评估；后治疗时的浪漫之爱，友谊和家族之爱；以及治疗前后的抑郁症。多层次建模显示，其他导向的和社会规定的完美主义与抑郁症的治疗后减少率较低有关，而路径分析表明，自我导向，其他导向的和社会规定的完美主义通过感知的缺乏间接预测抑郁症的治疗后下降率较低。优质的友谊。结果在临床背景下为完美主义社会断开模型提供了可信度和连贯性，并强调了在治疗完美主义患者时必须考虑到治疗外社会断开的重要性。（PsycINFO数据库记录（c）2020 APA，保留所有权利）。
