This study was conducted to evaluate the factor structure of the Research autonomy scale. The study was descriptive and correlational. The sample included all of the schools of humanities graduate students at Ferdowsi University of Mashhad to the number of 3199 people through Cochran formula 220 samples were determined and were selected via quota sampling. scale content validity by 8 experts from Ferdowsi University of Mashhad And based on the index CVI for all items of the scale were examined and inappropriate statements excluded. To verify the structure validity of the scale , exploratory and confirmatory factor analysis was used. The results of the analysis of the main components with the varimax rotation showed that the specific value 5 factors was significant , which explained 69.52% of the variance of the research autonomy scale. Goodness indicators confirmed the fit of the model. The internal consistency method (alpha coefficient) was used to determine the reliability of the research autonomy scale, The results showed that the total alpha coefficient scale 0/86 And the subscale Freedom of choice, ability to choose, Consciousnes, power of assessment and responsibility Respectively 0/74,0/75,0/78,0/70,0/72 were obtained. In sum, it can be said that the research autonomy scale had a satisfactory homogeneous consistency and sufficiently validity .
