We conducted a cross-sectional survey of women attending the HIV clinic between May and December 2011. Women were excluded if they were younger than 18 years, were accompanied by an adult or child aged 4 years or older, or were unable to give informed consent because of poor physical or mental health. We also excluded women with psychological conditions that the clinic’s psychology team felt placed them at high risk of severe distress as a consequence of participating. All participants were offered support from health Entinostat supplier advisors and psychologists.

They were also provided with information on local and national domestic violence agencies and generic HIV support agencies. Participants were asked whether they would like their clinic doctor to be provided with a copy of the questionnaire. If information was disclosed to the clinical team that raised serious concerns about the safety of the woman or any children, local clinic policies were followed for safeguarding children and vulnerable adults. Participants completed a standardized, structured questionnaire. It included the four questions in the HARK tool, which seeks to identify women experiencing physical, sexual or emotional IPV in the last year (see Fig. 1) [28]. The HARK tool was adapted from the Abuse Assessment Screen [29] and was validated against the Composite Abuse Scale [30]. We asked about experiences of IPV in the last

year and adapted the questions to ask about abuse experienced more than 1 year ago. We also asked about factors that have been associated with IPV

in previous studies, including age, ethnicity, level of educational attainment, employment, E7080 purchase immigration and marital status, parity, age at sexual debut, transactional sex, previous STIs, alcohol and substance misuse, history of mental health disorder, and past childhood physical and sexual abuse. The questionnaire was designed in consultation with experts in the field of IPV research and members of the clinic patient forum, and was piloted in 10 women. Trained Phosphoprotein phosphatase medical telephone interpreters were used with participants who did not speak sufficient English. For participants with poor literacy, the questionnaire was administered face to face by members of the research team. Relevant clinical data were obtained from medical records. IPV within the past 1 year was defined as having answered “yes” to at least one of the four HARK questions, with the experience occurring specifically within the past 1 year. We adapted the HARK questions to ask about lifetime IPV, and this was defined as answering “yes” to at least one of the four HARK adapted questions, with the experience having occurred at any point during a participant’s lifetime. Ethnicity was based on self-reported ethnicity and categorized as “African-born Black”, “other Black” (of Black ethnicity and born outside sub-Saharan Africa), “White” and “other” (comprising Asian and other ethnicities).
