The purpose of the current study was to examine Dutton's (1992) model of moderating and mediating variables which may impact the relationship of violence from an intimate partner with the development of posttraumatic stress disorder (PTSD) symptoms. This model was tested within three ethnic groups (African American, n = 303, Euro-American, n = 271, and Mexican American, n = 260), of low income, community women in serious, long-term relationships. The importance of the differences and similarities observed are discussed within a framework of the PTSD as well as domestic violence literature.
