The purpose of this research was to investigate the validity and reliability of the autonomous functioning questionnaire in high school students. This was a descriptive-correlational study of the type of psychometric studies. The students of the first and second high school levels of the 5th district of Tehran, who were studying in the second semester of the academic year 2023-2024, formed the statistical population of this study. Among these, 452 students were selected using a random multi-stage cluster sampling method and answered the autonomous functioning questionnaire (AFQ, Weinstein et al., 2012) and the basic psychological needs questionnaire (BPNQ, LaGuardia et al., 2000) using paper and pencil. Confirmatory factor analysis and concurrent validity were used to check the validity of the questionnaire and Cronbach's alpha coefficient was used to check the reliability of the questionnaire. The results of the confirmatory factor analysis indicated the confirmation of the three-factor structure proposed by the creators. The positive correlation between the autonomous functioning questionnaire and basic psychological needs confirmed the concurrent validity of the questionnaire (P<0.01, r=0.59). Cronbach's alpha coefficient of the questionnaire was obtained at the level of 0.77. In general, it can be concluded that the autonomous functioning questionnaire as a valid and reliable tool has the ability to be used to study and measure different dimensions of trait autonomy in Iranian students.
