In the current study, we investigated Construction & the psychometric properties of main psychological needs scale in Azad University students of Ahwaz in Iran. A sample of 200 adolescents, both males (n=100) and females (n=100) was selected from different Sector of University of Ahwaz Azad, Iran. The age of the sample ranged from 24 to 29 years, with a mean age of 23.69 years (Sd=1.14) for the total sample. We estimated the internal consistency reliability of the main psychological needs using cronbach's alpha. Results (by factors analysis) indicated that main psychological needs inventory combinated three factors as autonomy, competence & relatedness. We obtained cronbach's alpha of total factors 0.78, for autonomy 0.73, for competence 0.70 & for relatedness 0.70. Using confirmatory factor analysis showed hierarchical models were relatively satisfactory, and the three factor model had the best fit to the data. The Persian version of the instrument appeared to be a good measure for main psychological needs in Iran students.
