Sexual satisfaction and marital adjustment are the important aspects of married life that strictly affect the quality and stability of the relationship between couples. Studies have shown that several factors including psychological, social, economic, personal and demographic characteristics affect the sexual satisfaction and marital adjustment. The aim of the present study was to predict the levels of sexual satisfaction and marital adjustment based on job variables, commitment, intimacy and sexual knowledge and attitude. For this purpose, 100 employees of the Oil Company (50 expatriate, 50 non-employees) were selected as sample group using a convenience sampling method. Participants completed The Golombok-Rust Inventory of Sexual State Questionnaire (GRISS), The Golombok-Rust Inventory of Marital State Questionnaire (GRIMS), Table of job information, Dimensions of Commitment Inventory (DCI), Intimacy Scale (IS), and the Sexual Knowledge and Attitude Scale (SKAS). The results showed that no significant correlation existed between sexual satisfaction and marital adjustment with job variables, while the commitment, intimacy and sexual knowledge and attitude had a positive relationship with sexual satisfaction and marital adjustment. Also, sexual satisfaction could be predicted by intimacy and sexual knowledge and attitude. Marital adjustment was also predicted by the commitment and intimacy. The results also showed that among the variables, intimacy had the largest share in prediction of sexual satisfaction and commitment had the largest share in prediction of marital adjustment. Based on these findings, it can be concluded that job variables do not affect sexual satisfaction and marital adjustment, while the commitment, intimacy and sexual knowledge and attitude play a determining role in prediction of sexual satisfaction and marital adjustment.
