A valid questionnaire is a precursor to a sound measurement process. This study examined the psychometric properties of the Persian version of the Revised Competitive State Anxiety Inventory â€“ 2 (CSAI-2R). A total of 131 female Taekwondo athletes (Mean age =12.37 Â± 2.52) from Damghan completed CSAI-2R at competition venues. Confirmatory factor analysis was used to analyze the structure of CSAI-2R; a 1-factor model and a 3-factor model. CFA results revealed adequate model fit of the 3-factor model (X2= 189.52, df =113, P<0.001; PCFI=0.72, ECVI=1.85, RMSEA =0.06, GFI=0.87). A satisfactory level of alpha coefficient for the subscales (Î± =0.71 for somatic anxiety, 0.62 for cognitive anxiety and 0.74 for self-confidence). In conclusion, the data provide support for the 3-factor structure of CSAI-2R among female Persian taekwondo athletes. Future studies may extend the evidence to different types of validity and reliability in different age groups and gender.
