A preliminary investigation of the mediating roles of self-compassion and emotion dysregulation in the relationship between maladaptive perfectionism and obsessive-compulsive behaviors

Introduction

Recent research has highlighted an association between maladaptive perfectionism and obsessive-compulsive disorder (OCD). However, the mechanisms underlying this relationship are not well understood. The primary aim of this preliminary study was to investigate whether self-compassion and emotion dysregulation independently mediated this relationship. The secondary aim was to determine whether serial mediation existed between these factors. Whether these relations held for overall obsessive-compulsive (OC) symptoms, versus distinct dimensions of OCD, was also of interest.

Method

Three hundred and ninety-two university students (M_age = 21.81, SD = 8.01), predominantly female (79.18%), participated in an online questionnaire that included a dimensional measure of OCD. Scales assessing maladaptive perfectionism, self-compassion, emotion dysregulation, and negative emotion states were also included.

Results

Greater maladaptive perfectionism was related to more severe OCD. Emotion dysregulation, but not self-compassion, independently mediated this relationship. A serial mediation relationship was found, in that greater maladaptive perfectionism was associated with lower self-compassion, which was linked to greater emotion dysregulation, and in turn related to more severe OC behaviors. In addition, distinct patterns emerged for separate OC dimensions.

Conclusions

These findings highlight emotion regulation and self-compassion as potential targets for OCD prevention, especially in individuals with symptoms in the symmetry and unacceptable thoughts dimensions.
