(N=700). The design of this research is descriptive and research method has been correlated. To do so, we selected 364 students (166 females and 198 males) using multiphase cluster sampling. All the students were studying in BA degree at Bu-Ali Sina University of Hamedan, Iran. The study was conducted using a descriptive-correlative design. We used Fundamental Mental Needs' scale proposed by Gardia, Dessie and Ryan (2000), Young's early maladaptive schemas (1998), and Emotional regulation disorder (2004) to collect data. Research design was descriptive and its method was correlational. To analyze the data, we used structural equation model, correlation coefficient and T-test by using Amos 16 soft ware. The results showed that the empirical model of the data had a good fit with the conceptual model. According to the results, autonomy (0/003) and competence(p 0. 0001) as two componets of fundamental mental needs scale can influence the emotional adjustment disorder, in both direct and indirect ways.
