Quality of collaboration within health promotion partnerships: Impact on sense of community, empowerment, and perceived projects' outcomes

Community coalitions or intersectoral partnerships have long been advocated for the promotion of population health. In the present study, we assessed the quality of the functioning of health promotion partnerships created within a large community health promotion program implemented by the Emilia-Romagna region located in the north-east of Italy (2014-2016). In particular, we aimed to test the effectiveness of partnership working in strengthening participants' empowerment, sense of community and ultimately, the outcomes of a well-functioning partnership, conceptualized as including perceived effectiveness of health promotion interventions developed by the partnership, trust in their implementation and personal commitment in health promotion in the future. Participants were 238 stakeholders (e.g., health professionals, representatives of local administrations, teachers, representative of community and volunteer organizations, and citizens) formally included in six partnerships lead by six major local health services. Using Bayesian structural equation modeling, we found that a higher perceived quality of collaboration within the partnership enhances the outcomes of a well-functioning partnership, by strengthening their sense of a health-promoting community and empowerment. Sense of community responsibility did not predict future commitment in health promotion. The study findings suggest that community members' ownership and feeling of responsibility, as well as empowerment constitute positive partnership processes.
