In Portugal, heterosexual transmission of HIV has been growing in recent years, and has been shown to often occur within stable relationships. Serodiscordant couples may face significant challenges; however, little research has been conducted on close relationships and HIV, particularly adopting a dyadic and longitudinal approach and within the attachment theoretical framework. As existing approaches are often individually-focused, innovative methodologies need to be aligned with the current epidemiology of HIV. To strengthen couple-based approaches, research must consider the relationship dynamics that contribute to HIV risk behaviours and reproductive decisions.
This project aims to understand the psychosocial consequences of HIV serodiscordancy, focusing on high-risk sexual behaviours and motivations for childbearing, and emphasizing also the importance of considering dyadic effects by assessing both partners, as well as the reciprocal influences between partners. The results may impact research, healthcare and public-policies, especially providing evidence-based knowledge to develop more effective prevention and intervention programs.
