The study aimed to identify the relation between the marital compatibility and occupational stress among working women in Government Departments in Al Batinah South Governorate, Sultanate of Oman. This study was conducted on 150 working women (i.e. 4.1% of the original study population). The researcher used the Dyadic Adjustment Scale (DAS; Spanier, 1976) translated by (Frisa, 2013) and the Occupational Stress Scale (Al-Ghadaniyah, 2011), adopting The correlative descriptive approach was adopted in the study. The study indicated that the level of marital compatibility among working women was high according to the following dimensions: the consensus between a couple was the highest one with an average of (2.76), emotion expression came with an average of (2.70), harmony average was (2.26), and satisfaction average was (1.69). While the average level of occupational stress among working women was low. The dimension of supervision stress was the highest average one with (4.01); coworkers stress average was (3.97); working hours stress average was (3.90); management stress average was (3.76); convenience, change and professional growth stresses average was (3.70); the average of job nature stress was (3.58); and finally the financial stress average was (3.41). The results also showed a statistically significant reverse correlation at (α ≥ 0.01) between the marital compatibility and the occupational stress. Thus, the more the marital compatibility increases, the more the occupational stress decreases and vice versa among working women. In addition, the marital compatibility was predictor of the occupational stress level, since it explained about 13% of the variance in the occupational stress.
