Abuse is an extremely complex phenomenon, deeply rooted in gender-based power relations. In the Abagusii community, women abuse has been and is still taking place. Quite a number of women are left either physically injured or some die out of the same. This has brought a major set-back to development within this society. Abuse includes physical, sexual, psychological and economic abuse. This study was descriptive survey which was meant to find out the forms of abuse, the causes of abuse and the psychological impact of abuse.

Three administrative divisions were selected from three districts covering the Abagusii community; Kisii Central, Gucha District and Nyamira district. The main tool for data collection was a questionnaire. It was administered to both married and unmarried women. The data was analyzed descriptively using frequency tables, means and percentages. The research was meant to help the Kenyans society and other agents working in the country to recognize that women abuse was and still a serious problem impending development as well as violating human right issues of its victims, particularly women. This was also meant to create awareness of the vice. The findings indicated that several forms of abuse exists in the Abagusii community which were due to inequality between men and women, patterns of using violence to resolve conflicts, male authority and control of decision making and transgression of gender roles.
