Positive psychological communication and sustainable human capital development: Introducing the PPCF conceptual framework

Organisations increasingly invest in skills, technology and talent systems, but their long-term value depends on a workplace where employees feel safe to speak up, valued for their contributions, connected to others and motivated by meaningful work. This conceptual article introduces the Positive Psychological Communication Framework (PPCF), which explains how organisational communication can function as a resource-building process rather than merely an information-delivery mechanism. Using an integrative conceptual synthesis of Human Capital Theory, Positive Psychology, Positive Organisational Scholarship and organisational communication, the article identifies six mutually reinforcing dimensions: positive emotion, trust building, psychological safety, meaning and purpose, strengths recognition, and social connectedness. PPCF proposes that these dimensions support employee engagement, learning agility, resilience, knowledge sharing and collaboration, thereby strengthening sustainable human capital at individual, team, organisational and societal levels. The framework makes three contributions. First, it positions communication as an antecedent of psychological resources. Second, it provides a multilevel pathway connecting everyday communication practices with sustainable human capital development. Third, it places employee flourishing within the social dimension of organisational sustainability. The article also specifies boundary conditions, conceptual propositions, practical applications and an empirical validation agenda. PPCF is presented as a testable conceptual framework rather than an empirically confirmed causal model.
