This study examined correlates of posttraumatic stress disorder (PTSD) and mental health service seeking for women sexually assaulted in childhood and/or adulthood (N = 619) identified from the National Comorbidity Survey (1990–1992). Factors related to correlates of PTSD and mental health service seeking varied according to sexual assault history. Ethnic minority women with less formal education, more traumatic and stressful life events, and longer duration of sexual abuse had greater odds of PTSD within certain sexual assault history subgroups. Mental health service seeking was predicted by demographics (e.g., more education, Caucasian race), as well as other psychosocial factors (e.g., life events, social support), and medical insurance status, especially for adult sexual assault victims. Implications for mental health treatment and intervention are drawn for women with different sexual assault histories. © 2002 Wiley Periodicals, Inc.
