Self-criticism, Strivings and Aggressive Behavior in Spanish Children: The Two Sides of Self-Oriented Perfectionism.

Abstract

This study analyzes the relationship between the two intrapersonal perfectionism dimensions (i.e., Self-Oriented Perfectionism-Critical, SOP-C, and Self-Oriented Perfectionism-Strivings, SOP-S) and the components of aggressive behavior (cognitive, emotional and motor) in a sample of 804 (48.3% females) Spanish students between the ages of 8 and 11 (M = 9.57; DE = 1.12). The Spanish versions of the SOP-C and SOP-S subscales of the Child/Adolescent Perfectionism Scale and the Aggression Questionnaire were used. Students with high SOP-C scored significantly higher (p < .001) than their peers with low SOP-C on all components of aggressive behavior. The magnitude of these differences (Cohen's d index) ranged from .40 to .59. In contrast, non-significant statistical differences were found between students with high and low SOP-S. Moreover, logistic regression analysis revealed that SOP-C significantly and positively predicted high Hostility, Anger and Physical and Verbal Aggression, whereas none of these components were significantly predicted by SOP-S (95% CI). Results are discussed, taking into account the debate on the conceptualization and nature of intrapersonal perfectionism.
