Determining the Validity an‎d Reliability of the Sport Decision-Making Preferences Test

رفتار حركتي و مديريت ورزش

The DPEX test was developed by Time an‎d Bran‎d (2024) as a computer-based instrument designed to assess individuals’ preferences for physical activity using a set of visual stimuli. Since this tool had not previously undergone psychometric eva‎luation in Iran, it was necessary to examine its measurement properties within the cultural an‎d sporting context of the country. The purpose of the present study was to determine the validity an‎d reliability of the Sports Preference Test (DPEX) in an Iranian population.This study was descriptive in nature an‎d applied in its objectives. The statistical population consisted of all adults over 18 years of age living in the city of Isfahan. The sample included 384 participants (186 women an‎d 198 men) selec‎ted through convenience sampling. Data were collected using the DPEX Sports Preference Test. To eva‎luate concurrent criterion validity, the General Physical Activity Preference Questionnaire an‎d the Sport Participation Motivation Questionnaire—both previously validated instruments—were used. Data analysis involved Cronbach’s alpha to assess internal consistency, the intraclass correlation coefficient (ICC) to determine test–retest reliability, an‎d Pearson correlation coefficients to eva‎luate concurrent criterion validity. The results indicated that both Cronbach’s alpha an‎d ICC values exceeded 0.70, demonstrating excellent reliability of the instrument. Moreover, significant positive correlations were found between DPEX scores an‎d scores on the two questionnaires, confirming the concurrent criterion validity of the tool. Overall, the findings indicated that the Sports Preference Test (DPEX) possesses satisfactory validity an‎d reliability an‎d can be used as a credible instrument for assessing sports preferences among athletes, students, an‎d individuals interested in physical activity in Iran. These results contribute to the development of culturally appropriate assessment tools in the field of sport psychology an‎d support the identification of individual tendencies in the selec‎tion of physical activities
