predictive role of emotional dysregulation,repetitive negative thinking, intolerance of uncertainty and experiential avoidance in positive and negative perfectionism

The present study was conducted to investigate predictive role of emotional dysregulation, intolerance of uncertainty, experiential avoidance and repetitive negative thinking in positive and negative perfectionism. In this study, 412 B.S students of Tehran university, Allameh Tabatabei and Kharazmi university participated as sample. Data collected by filling 4 questionnaires: The positive and negative perfectionism (PANP), repetitive negative thinking questionnaire (RNTQ), disorder in emotion regulation scale (DERS), intolerance of uncertainty scale (IUS) multidimensional experiential avoidance questionnaire (MEAQ). Data was analyzed by structural equations modeling. Findings: All study variables except experiential avoidance coorelated with positive and negative perfectionism. The multiple regression analysis indicated that the predictive model for positive perfectionism respectively consisted of emotional dysregulation, intolerance of uncertainty and repetitive negative thinking. And for negative perfectionism respectively consisted of intolerance of uncertainty, repetitive negative thinking and emotional dysregulation.These variables account for %11/5 of the positive perfectionism variance and %44/4 of negative perfectionism.
Positive and negative perfectionism are two different structural models, with cognitive, models, with cognitive, emotional and behavioral mechanisms.
