Psychosocial health challenges remain pervasive among Southern African Indigenous communities, yet prevailing Western-oriented intervention models often inadequately address the cultural and contextual realities of these populations. This disconnect underscores the need for culturally congruent frameworks grounded in Indigenous knowledge systems and community participation. This study aims to confirm and validate a hypothetical model for psychosocial health management among Southern African Indigenous communities, developed during an earlier phase of a broader community-informed research project. A non-experimental quantitative design was employed to assess the model’s content validity and comprehensiveness. Expert evaluation was conducted using the Content Validity Index (CVI) and Content Validity Ratio (CVR), and inter-rater reliability was assessed using Kappa statistics. The findings demonstrate that psychosocial health is best understood as a lifelong process of achieving and maintaining balance across interconnected social, cultural, spiritual, psychological, and communal domains. The model was confirmed as both content valid and comprehensive, highlighting the significance of community participation, shared belief systems, spiritual realm, resilience, and culturally embedded healing practices in the management of psychosocial health. Its confirmation provides a critical foundation for future intervention development, policy development, and psychosocial health practice within Indigenous contexts.
