Factor Structure, Validity and Reliability of Sources of Acute Stress among Wrestling Questionnaire (SASWQ)

This study aimed at exploring the main sources of acute stress in wrestlers regarding the structure and the assessment of reliability and validity of the sources of acute stress in wrestlers questionnaire (SASWQ). For this purpose, this questionnaire was distributed among a sample of 330 wrestlers (mean age 21.56+5.3) in Tehran who were selected by multistage random sampling method. Analysis of data with SPSS software showed that the Cronbach's alpha for all items of this questionnaire was 0.909 and alpha coefficient of the internal consistency for the first and second section was 0.870 and 0.831 respectively. Content validity of the questionnaire showed the equity of each of the 8 principle components of acute stress in wrestlers including skill performance, evaluation, contest, error, prospect, time pressure, injury and environment as 2.43 on average through exploratory factor analysis in the principle component analysis (PCA) with Varimax rotation. In confirmatory factor analysis with Lisrel software, GFI=0.96, AGFI=0.92 and CFI=0.93 were obtained. The findings showed that SASWQ had acceptable reliability and validity and could measure the mentioned variable in the mentioned statistical population.
