Violence against women is frequent, and has serious consequences for their physical and mental health. Until now, a common response of health services and professionals to victims has been the denial of the violence. The aims of this study were to estimate the prevalence of present and past violence among women attending social and health services in Trieste (Italy) for any reasons, and to evaluate the feasibility of asking them about violence. Five public health care facilities were involved: a hospital-based Emergency Department, two "Consultorio Familiare", and two community-based Social service centers. The final sample consisted of 510 women; the response rate among eligible women was 76% across all facilities. The study revealed a high prevalence of different kinds of violence, mostly perpetrated by men well known to the victim. Among the women interviewed, 10.2% had experienced physical/sexual violence in the last 12 months, regardless of perpetrator. Violence by a male partner or former partner, occurred in 6.4% of women; by other relatives, 1.6% of women; and by "other" persons 3.3% of women. The results demonstrated the feasibility of "asking about violence" in all cases; moreover, those women who had been abused were often eager to talk about it. A systematic approach to the issue of violence is a necessary condition for responding appropriately to the needs of women who have experienced or are experiencing violence. Nevertheless, to avoid the replication of a common bias against victims of violence, health and social personnel should be appropriately trained before "asking all cases" becomes a policy within health and social services.
