In recent years, doping behavior has expanded beyond professional sports and become increasingly visible in fitness and recreational contexts. Given the absence of a relevant measurement tool in Turkish, this study aimed to adapt “the Questionnaire of Attitudes towards Doping in Fitness (QAD-Fit)” into Turkish culture and provide a valid instrument for the field. The QAD-Fit, developed to assess attitudes toward doping in fitness settings, consists of 16 items across four subscales (attitudes, subjective norms, beliefs, and intentions) rated on a seven-point Likert scale. The sample included 337 individuals (124 females, 213 males; M = 24.31, SD = 6.998) who engage in fitness activities. Following linguistic validation, exploratory and confirmatory factor analyses were conducted to examine construct validity. Exploratory factor analysis results revealed a three-factor structure explaining 62.86% of the total variance (42.04%, 12.64%, and 8.18%, respectively). During confirmatory factor analysis, high-covariance residuals were added to improve model fit, and item 5 was removed. The revised model demonstrated acceptable fit indices. The Cronbach’s Alpha coefficient was found to be .88, while the internal consistency coefficients of the subscales ranged between .60 and .93. Additionally, the test-retest correlation conducted with a 25-day interval was determined to be .81. In conclusion, the Turkish adaptation of the QAD-Fit scale can be considered a psychometrically valid and reliable tool for assessing attitudes toward doping behavior among individuals in a fitness environment.
