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.
