The aim of this study was to investigate the psychometric properties of the Basic Psychological Needs Satisfaction and Frustration Scale (BPNSFS). Two hundred and fifteen students were selected from Shiraz University by means of multistage cluster sampling method, and following scales were given them to responds Basic Psychological Needs Satisfaction and Frustration Scale (Chen, et.al, 2015), To confirm Vatality of the Scale (Ryan & Frederick, 1997), Aggression Questionnaire (Buss & Perry, 1992), and Satisfaction with Life Scale (Diner, et.al, 1985). To determine the validity of the Basic Psychological Needs Satisfaction and Frustration Scale, confirmatory factor analysis by structural equation modeling using AMOS software and convergent and divergent validity methods were used. Also, positive correlation between needs satisfaction, state vitality, and life satisfaction, negative correlation between needs frustration, and these variables, and positive correlation between needs frustration and aggression, confirmed the convergent and divergent validity of this scale. To determine the reliability, Cronbach's coefficient alpha was used. Range of coefficients was 0.68 to 0.85. Results indicated that BPNSFS is a valid instrument for the use in Iranian society.
