The efficacy of group psychotherapy for adults with perfectionism: A randomized controlled trial of dynamic-relational therapy versus psychodynamic supportive therapy.

OBJECTIVE

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.

HYPOTHESIS

Psychodynamically informed therapies, particularly DRT, will be efficacious in treating perfectionism and functioning outcomes.

METHOD

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.

RESULTS

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.

CONCLUSION

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).
