Perfectionism in patients with eating disorders: The role of metacognitive beliefs and repetitive negative thinking.

INTRODUCTION

Using the Self-Regulatory Executive Function model as a basis, this study explored whether, in patients with eating disorders (EDs), metacognitions and repetitive negative thinking are associated with higher levels of perfectionisms.

METHODS

One hundred twenty-three outpatients with EDs were recruited. Perfectionism, metacognitive beliefs, worry, rumination, anger rumination, affective and eating symptoms were assessed. Correlation and hierarchal regression analyses were run.

RESULTS

Higher endorsement of positive beliefs about worry was associated with higher levels of 'personal standards perfectionism'. Higher endorsement of positive beliefs about worry, need to control thoughts, worry and rumination was associated with higher levels of 'concern over mistakes perfectionism'.

CONCLUSIONS

Among patients with EDs, perfectionism appears to be associated with the endorsement of dysfunctional metacognitive beliefs, worry and rumination. Dysfunctional metacognitive beliefs and repetitive negative thinking could be suitable therapeutic targets to reduce the levels of perfectionism among patients with EDs.
