Self-criticism as a mediator in the relationship between unhealthy perfectionism and distress

Unhealthy or negative perfectionism has been identified as both a risk and maintaining factor for a range of psychological difficulties. A cross-sectional online study with a predominantly student population (n = 381) investigated cognitive processes suggested to mediate the relationship between unhealthy perfectionism and distress. Hypothesised cognitive processes were assessed using questionnaires about rumination, habitual self-critical thinking, unhelpful beliefs about emotions, self-compassion and mindfulness. Factor analysis of these questionnaires suggested two distinct underlying constructs, labelled self-criticism and present-moment awareness. Higher levels of self-criticism were associated with unhealthy perfectionism and psychological distress, and partially mediated this relationship.

These findings are consistent with the possibility that repetitive or habitual self-critical thinking is a process through which unhealthy perfectionism may result in greater distress. Future research could investigate whether interventions targeting self-criticism may help to reduce distress in individuals with high levels of unhealthy
