The aim of this study was to examine the associations between adverse childhood experiences (ACEs) and the high levels of social service usage by women who are sex trafficked. Fifty (N = 50) women who were sex trafficked were surveyed using purposive and snowball sampling methods. The ACEs score for respondents ranged from 2 to 10 with an average score of 7.4 (SD = 2.3). Emotional and sexual abuse tied at 88 percent as the most frequently cited ACEs among the women in this sample. The prevalence of ACEs was significantly higher in this sample compared with known estimates in similar populations, ranging from 20 percent to 54 percent (p < .001). Considering the well-established link between ACEs and poor health outcomes, these findings point to the need for innovative and targeted social service provisions to women who were formerly sex trafficked that take into consideration the high level of ACEs of the women. Given the sociodemographic diversity of this sample, there is a need for services that are trauma-informed, innovative, and culturally sensitive in a variety of social service settings.
