Delayed HIV testing in HIV-positive sub-Saharan Africans

Abstract

There is evidence that some sub-Saharan African individuals suspect that they are HIV positive before diagnosis but delay being tested for HIV. This increases the likelihood of being diagnosed late (with a severely compromised immune system), a phenomenon that has been observed in sub-Saharan Africans diagnosed in the UK. Late diagnosis has negative personal and public health consequences. There is a lack of understanding of the psychological processes associated with delayed HIV-testing. This study used a Grounded Theory methodology. It aimed to produce a theoretical model to explain the psychological processes associated with delayed HIV testing in sub-Saharan Africans in the UK but also how these processes changed over time and contributed to the decision to test. Seven HIV-positive sub-Saharan African individuals from a London HIV clinic and one from a HIV charity were interviewed about their experiences. Analysis led to the development of a theoretical model of delayed HIV testing. This model consisted of three theoretical codes: moving in and out of uncertainty about HIV infection; preferring not to know HIV status; and making the decision to test for HIV. Participants' HIV risk perception fluctuated and was characterised by uncertainty. This, in combination with a preference to not know their HIV status due to a number of feared consequences of being HIV-positive, deterred them from testing. Participants' thoughts and feelings about knowing their HIV status changed over time. These changes were that they: wanted certainty, had hope of being HIV-negative and/or a hope for treatment and life and preparing for and accepting a potentially positive result. The findings can inform interventions to reduce delayed testing and suggest: a) intervening with ambivalence on an individual level and b) promoting awareness of HIV c) promoting the benefits of testing/costs of not testing at a population level. The findings are discussed in relation to existing research and theory. Strengths and limitations of the study are discussed, as are clinical implications and suggestions for future research.
