Most of studies in the area of Type-A behaviour have been focussed on male professionals. Today, when gap between men and women is shrinking, as women of these days want to live life as they like and to come at par with the male-folk, divorce rates are increasing and women greatly outnumber men on depression rates, such study on female professionals becomes imperative. Present investigation is an attempt in this direction, and aimed at studying the relationship of Type-A behaviour pattern with physical and mental health of working women belonging to four groups viz., Govt. Officers, Govt. Doctors, Bank Officers and University teachers. 400 working women 100 from each group under study from Rajasthan were investigated using Jenkins Activity Survey Form C, Physical Health Spectrum by Belloc et. al., Mental Health Inventory by Jagdish and Shrivastava and Indian Adaptation of NSQ by Kapoor and Kapoor. Based on the findings, it can be concluded that type-A behaviour pattern amongst working women tend to have adverse impact on their physical as well as mental health, specially under conditions of intense pressure and stress, which seem to be more for doctors.
