TURKISH VALIDATION AND RELIABILITY STUDY OF PERFORMANCE ENHANCEMENT ATTITUDE SCALE

Abstract

According to the majority of researchers, “attitudes” are the main determinants in using doping substances. The Performance Enhancement Attitude Scale (PEAS), constituting one of the examples in this context, is a 17-item self-report scale. In the present study, it was aimed to determine the validity and reliability of the Turkish version of PEAS. The scale was conducted among 224 licensed athletes over the age of 18. A construct analysis was applied. Factor analysis was performed to assess the construct validity and to examine construct reliability. Intraclass Correlation Coefficient (ICC) test was carried out to evaluate test-retest reliability. Confirmatory factor analysis was performed to assess the factor structure of the scale. To assess the validity of the scale, The Attitude Scale Related to the Use of Doping (ASRUD) was used. In the exploratory factor analysis of 17 item one-dimensional scale, it was found that the factor loadings vary between 0.298 and 0.700, excluding items 1 and 7, which had low factor loadings. According to the confirmatory factor analysis, fit and fit indices of the scale were low in first and seventh items and acceptable in other items, as in exploratory factor analysis. RMSEA value was found as 0.086. As a result of the method used to test the validity, there was a negative correlation between PEAS and ASRUD scores (r=-0.302; p<0.001). Cronbach’s alpha coefficient was 0.822 and ICC was 0.897. This study suggests that PEAS is a valid and reliable scale to assess performance enhancement attitudes in Turkey.
