The present study intended to identify environmental and socio-demographic factors that are predictive of acceptance of HIV testing in order to extend the Theory of Planned Behaviour model (TPB), which will better explain the health-related behaviour under investigation. Data analysed using multiple regression were obtained by means of a cross-sectional face-to-face questionnaire administered by trained interviewers. The study proceeded to a mixed two-stage stratified random, cluster random and quota sampling to sample the population of under investigation. It is clear from the findings that only the levels of education and knowledge about the meaning of HIV/AIDS are eligible to be incorporated alongside the traditional TPB components in order to improve the model. Although both level of education and level of knowledge are statistically significant predictors of acceptance of HIV testing, the first variable made the strongest contribution.
