RESUMO
Background: The Woman Abuse Screening Tool (WAST) is a screening tool for domestic violence used in Unites States. Aim: To carry out the cultural adaptation of the WAST instrument for early detection of domestic violence in primary health care. Material and Methods: Qualitative techniques for cultural adaptation were used in stages 1 and 2 and quantitative techniques were used in stage 3. The validity of content was assessed using judge tests carried out with experts in the field. Linguistic adaptation was carried out using a focal group technique to ensure semantic and language comprehension. Finally, the culturally adapted instrument was applied to 16 women who were victims of violence and to 28 women without a history of violence. Results: For cultural adaptation, the judges' test added the item of economic violence to the instrument. According to the focus groups, some words were changed to facilitate understanding by the subjects. According to the scores obtained in women with and without a history of violence, a cut-off point of 15 points was defined to determine a history of domestic violence with a sensitivity of 100% and a specificity of 96%. The Cronbach Alpha of the questionnaire was 91%. Conclusions: WAST is an effective and easily applied instrument for the early detection of domestic violence.
