Eating Disorders, Perfectionism, and Quality of Life: Maladaptive Perfectionism as a Mediator Between Symptoms of Disordered Eating and Quality of Life.

Individuals with disordered eating behaviors exhibit significantly impaired quality of life (QoL). Maladaptive perfectionism is consistently associated with both eating disorders (EDs) and QoL, but its role in the relationship between eating pathology and QoL has remained largely unexplored. The current study investigated whether maladaptive perfectionism mediates the ED-QoL relationship. A total of 286 university students completed an online survey that consisted of self-report questionnaires assessing ED symptomology, QoL, maladaptive perfectionism, and anxiety and depression symptoms. Maladaptive perfectionism mediated the relationship between ED symptomology and QoL, but this effect did not persist when body mass index, depression, and anxiety were controlled for. The results suggest the mediatory effect of maladaptive perfectionism is masked by depression and anxiety symptomology. Recommendations for further research are proposed to clarify the role of maladaptive perfectionism in the ED-QoL relationship and to explore the mediatory role of depression and anxiety in this relationship.
