For statistical analysis, SEM was used in Amos software, version 24.
Results The results of data analysis showed irrational relationship beliefs had a negative relationship with marital satisfaction (r=-0.41; P<0.01), while sexual function (r=0.46; P<0.01) and basic psychological needs (r=0.56; P<0.01) had a positive relationship with marital satisfaction. Also, the indirect relationship between irrational relationship beliefs and marital satisfaction was negative and significant(β=-0.189, P=0.001), and the indirect relationship between sexual function and marital satisfaction was positive and significant (β=0.116, P=0.001).
