We administered the present research to study the role of levels of self concept and perceived organizational justice on males and females psychological commitment. The statistical population included some workers of public sector organizations, among whom 305 persons (215 males and 90 females) were selected using stratified random sampling. Research questionnaires consisted of: levels of self-concept scale, distributive justice questionnaire, procedural and relational justice questionnaire and psychological commitment questionnaire. Data were analyzed using Pearson's correlation coefficient, hierarchical regression analysis and independent sample t test. The results showed that: 1) There is significant difference between males and females in relational justice. 2) For males in the first block of hierarchical regression analysis, distributive justice, procedural justice and relational justice have significant relationships with psychological commitment (P<0.05), but for females in first block, relational justice and then procedural justice have positive relationship with psychological commitment. 3) In the second block with adding the levels of self-concept, individual self-concept for males, and relational self-concept for females have significant relationship with psychological commitment (p<0.05). Findings of this research revealed that relational self-concept and relational justice are important for women's psychological commitment, whereas for male's psychological commitment, individual self-concept and distributive justice bear significance.
