Psychometric Properties of Persian Version of Sport Grid-Revised: Distinguishing Arousal from Cognitive Anxiety in Disaster Theory

The purpose of this study was to determine the psychometric properties of Persian version of Revised Sport Grid, which is an effective tool to assess physiologic arousal and cognitive anxiety and their distinguishing in the framework of disaster theory. Therefore,two hundreds and eighteen athletes with two levels of skill, skilled (96 persons), less-experience (122 persons) in five sport types (Archery, TableTennis,Badminton,Basketball & Volleyball), were selected by goal oriented sampling and completed the Revised Sport Grid, Competitive State Anxiety Inventory-2 and Sport Competition Anxiety test questionnaire. We confirmed the face validity, content validity (0.91) and temporal reliability (with use of intra-class correlation coefficient in test-retest method, arousal=0.77, cognitive anxiety=0.86). The convergent, discriminant and concurrent validity were confirmed by Pearson correlation coefficient, and the construct validity was confirmed by independent t test. Therefore, the Persian version of Revised Sport Grid has psychometric properties for measuring the athletes’ arousal and cognitive anxiety immediately before competition.
