This randomized controlled trial investigated the efficacy of group dynamic-relational therapy (DRT) relative to group psychodynamic supportive therapy (PST) in treating perfectionism and improving psychological functioning.
Psychodynamically informed therapies, particularly DRT, will be efficacious in treating perfectionism and functioning outcomes.
Based on a comprehensive conceptualization of perfectionism, 80 community-recruited, highly perfectionistic individuals were randomly allocated to 12 sessions of group DRT (n = 41; 5 groups) or group PST (n = 39; 5 groups). Patients completed measures of trait perfectionism, perfectionistic self-presentation, perfectionistic cognitions, symptom distress, life satisfaction, and work and social adjustment at pre-, mid-, and posttreatment and 6 months posttreatment.
Multigroup latent growth curve modeling revealed significant (p < .05) decreases in all perfectionism components and improvements in all functioning outcomes from pretreatment to 6-month follow-up in both DRT and PST. Likewise, analyses revealed substantial reliable improvement across conditions for all perfectionism components. Last, moderate-to-large between-group differences favoring DRT over PST were found for self-oriented perfectionism, perfectionistic self-promotion, nondisplay of imperfection, nondisclosure of imperfection, and work and social adjustment.
Findings provide evidence for the use of psychodynamic approaches in the treatment of perfectionism and support the relative efficacy of DRT for components of perfectionism. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
本随机对照试验旨在研究团体动态关系治疗（DRT）相对于团体心理动力支持治疗（PST）在治疗完美主义和改善心理功能方面的疗效。
受心理动力学启发的疗法，特别是 DRT，将在治疗完美主义和功能结果方面有效。
基于对完美主义的全面概念化，80 名从社区招募的、高度完美主义的个体被随机分配到 12 节团体 DRT（n = 41；5 组）或团体 PST（n = 39；5 组）中。患者在治疗前、治疗中期和治疗后以及治疗后 6 个月完成了特质完美主义、完美主义自我呈现、完美主义认知、症状困扰、生活满意度以及工作和社会调整的测量。
多群组潜在增长曲线模型显示，在 DRT 和 PST 中，所有完美主义成分都有显著（p <.05）下降，所有功能结果都从治疗前到 6 个月随访期都有所改善。同样，分析显示，所有完美主义成分在所有条件下都有实质性的可靠改善。最后，发现 DRT 相对于 PST 对自我导向的完美主义、完美主义的自我提升、不表现不完美、不披露不完美以及工作和社会调整具有中等至较大的组间差异。
研究结果为心理动力学方法在治疗完美主义中的应用提供了证据，并支持 DRT 在完美主义成分方面的相对疗效。
