Abstract: The present research was taken up with broad objective to study the marital adjustment and mental health in middle aged couples (40-55 years) from Delhi, India. The sample comprised of 100 working couples (n=200) which are bank employees and doctors, within the age range of 40-55 years from Delhi, India. It was seen that in bank employees, autonomy was positively correlated with family adjustment, positive self evaluation and financial adjustment. In middle aged doctors, autonomy was positively correlated with family adjustment and social adjustment; whereas integration of personality was found correlated with role distribution. On the other side, perception of reality was negatively correlated with recreational adjustment and role distribution. A significant interactive affect of job and age, was found on marital adjustment, mental health of middle aged couples.
