Abstract
The study conceptualizes locus of control as a behavioural mechanism for HIV and AIDS prevention. The locus of control variables that could build the model are: social systems control, self-control, fatalism, achievement-oriented behaviour, willingness to delay gratification, personal values and expectations, and alienation. This study seeks to investigate the possibility of designing a locus of control-based HIV and AIDS model that can be used in South Africa to complement existing health promotion models. While other models tend to take an exploratory approach in which various factors are put together to explain HIV and AIDS risk and prevention, the envisaged model seeks to focus on personality-related factors of Rotter's social learning theory. The model design involves the use of statistical modeling in predicting HIV and AIDS risk.
