Abstract
The purpose of this study is to determine the validity and reliability of Farsi version of competitive aggressiveness and anger scale among athletes. For this purpose, 403 male athletes from different sports by means of cluster random sampling were selected and completed translated version of competitive anger and aggressiveness scale. Data were analyzed by means of exploratory factor analysis, Cranach alpha, Pearson correlation coefficient, intraclass correlation coefficient, ANOVA with Bonferroni post hoc and Confirmatory factor analysis test. Data showed two factors predicted 43.32 percent of variance. Internal consistency by Cranach alpha for whole of scale and subscales were equal to 0.78, 0.74 and 0.68 respectively. Relationship among of subscales and whole scale showed the translated scale was acceptable internal consistency. Relationship between translated scale and moral content judgment in sport scale showed that the competitive anger and aggressiveness in sport has good convergent construct validity (r=-0.219). Also, it was shown there is significant difference among sports in aggressiveness subscale that showed acceptable group construct validity. Data showed all values indicated a good fit model with GFI = .92, CFI = .91 that was showed in this questionnaire two factors and six item for each factor were obtained. Intraclass correlations showed this scale has acceptable temporal reliability (anger: 0.90, aggressiveness: 0.84 and whole of scale: 0.91). It was concluded that translated scale of the competitive aggressiveness and anger has acceptable validity and reliability among athletes and has the usability by athletes, trainers, and researchers.
