This project investigated the reasons for delayed HIV testing, particularly among people from culturally and linguistically diverse backgrounds. The project had two components, one quantitative, the other qualitative. The quantitative component collected demographic and socioeconomic data, along with data about people’s use of health services, attitudes towards HIV and perceptions of stigma. These were linked with the patients’ HIV-related clinical data to identify patients who were diagnosed late and the reasons for their late diagnosis. The qualitative component followed up the survey and approximately 20 HIV patients from culturally and linguistically diverse backgrounds were interviewed. These interviews explored in depth some of the issues covered in the survey, in particular issues relating to patients’ use of health services. Data collection was completed in 2007 and the project was completed in 2008.
