The health and well-being impacts of a work integration social enterprise from a systems perspective.

Recent research has drawn upon the social determinants of health (SDH) framework to attempt to systematize the relationship between social enterprise and health. In this article, we adopt a realist evaluation approach to conceptualize social enterprises, and work integration social enterprises in particular, as 'complex interventions' that necessarily produce differential health outcomes for their beneficiaries, communities and staff. Drawing upon the findings from four social enterprises involving a range of methods including 93 semi-structured interviews with employees, managers and enterprise partners, together with participant observation, we demonstrate that these health outcomes are influenced by a limitless mix of complex and dynamic interactions between systems, settings, spaces, relationships and organizational and personal factors that cannot be distilled by questions of causality and attribution found in controlled trial designs. Given the increased policy focus on the potential of social enterprises to affect the SDH, this article seeks to respond to evidence gaps about the mechanisms and contexts through which social enterprises promote or constrain health outcomes, and thereby provide greater clarity about how research evidence can be used to support the social enterprise sector and policy development more broadly.
