Several researches across the African continent highlight the important role of “marital status” in the magnitude of the HIV/AIDS epidemic because of early marriage for women and peers’ influence to engage in extramarital sex for men. Thus, the present study investigated the existence of significant differences in marital groups regarding their level of HIV/AIDS awareness, attitude towards infected persons, exposure to HIV/AIDS information, accessibility to condoms and sexual behaviour. The results emanating from the statistical analyses of the data collected through a cross - sectional survey revealed that “marital status” is the key to the design and implementation of HIV/AIDS interventions in Kinshasa.

This study investigated the need to extend the TPB model to SMBE variables as suggested by Ayikwa and De Jager (2017) in the quest to better understand sexual behavioural patterns using the Confirmatory Factor Analysis (CFA) approach. The main research question to be answered: "how the TPB and SMBE variables should be structured into a validated CFA model?" Data were carefully collected in South Africa’s Gauteng Province using a disproportionate multi-stage stratified random sampling method to retain 607 respondents. The survey questionnaires distributed consisted of revisited pre-existing instruments. The data were then analysed by CFA model that followed Exploratory Factor Analysis (EFA) to determine the suitability of the sample size. Assessment of the second order extended TPB model confirmed that it is worthwhile to integrate SMBE variables while extending the TPB model in the context of HIV/AIDS related behaviours.
