Effects of a brief self-compassion intervention for college students with impostor phenomenon.

The present study used a latent growth curve modeling approach to (a) examine the effectiveness of a brief self-compassion intervention on reducing impostor phenomenon, maladaptive perfectionism, and psychological distress and (b) explore who would benefit more from this intervention. A total of 227 college students at a large Midwest university were randomly assigned to participate in either a 4-week brief self-compassion intervention group or a nonintervention control group. Analyses of the effectiveness of the intervention suggested the brief self-compassion intervention had significant treatment effects for reducing impostor phenomenon and maladaptive perfectionism. Moreover, this study also examined whether participants with different levels of fear of self-compassion and core self-evaluation would report different levels of treatment effectiveness. Fear of self-compassion was found to be a significant moderator of the intervention effects in reducing maladaptive perfectionism and psychological distress. Specifically, participants in the intervention group with higher levels of fear of self-compassion reported a greater decline in both maladaptive perfectionism and psychological distress over time when compared to those with lower levels of fear of self-compassion. Core self-evaluation significantly moderated the effectiveness of this intervention in reducing participants' levels of impostor phenomenon and maladaptive perfectionism. Specifically, participants in the intervention group with lower core self-evaluation reported a greater reduction in maladaptive perfectionism over time when compared to those with higher core self-evaluation.
