The study investigates how the church in Zambia can effectively facilitate change toward reducing HIV-risky behaviour. The researcher posits that an intricate connection exists between HIV-risky behaviour and the socio-cultural context of majority people groups in Zambia. He further argues that much risky behaviour is imbedded in pervasive socio-cultural norms and traditions propelled by a worldview which essentially resists transformation. From an insider’s perspective the researcher will design a praxis model for transforming Zambian worldview facets with regard to HIV/AIDS predisposing behaviours in order to achieve enduring HIV risk reduction. The study reviews current literature on HIV behavioural change theories and models to understand where the theories have taken all the stakeholders, including theological praxis. The study will demonstrate the link between Zambian cultural worldviews and trends in sexual behaviour which, arguably, facilitates the proliferation of HIV risky behaviour. The study culminates in designing an evangelical theological praxis/model for transforming relevant cultural worldviews toward changing HIV risky behaviour in Zambia.
