Abstract
Perfectionism has long been established as a perpetuating factor of eating disorder symptoms. Simultaneously, satisfaction with the psychological needs for autonomy, competence, and relatedness as conceived within self-determination theory boosts individuals’ well-being and in turn, poses shielding from several psychopathologies. The present research explores the dynamics between perfectionism and eating disorder symptoms by proposing a buffering effect of self-determination resulting from satisfaction with the basic psychological needs. Four hundred seventy-seven participants completed a survey measuring the variables under consideration. Eating disorder symptom variations were assessed by performing a simple linear regression, investigating each psychological need as a moderator interacting with perfectionism. As hypothesized, perfectionism is positively associated, and the individual psychological needs are negatively associated with eating disorder symptoms. Unexpectedly, the moderator analyses involving the interaction effects between perfectionism and the psychological needs have failed to show significance. This paper contributes to the relevant body of research by emphasizing the complexity of the reciprocity between perfectionism and self-determination. It is crucial to investigate the web of explored variables further to enhance the comprehension of eating disorder symptoms.
