Intersectoral collaboration and community voice in a marginalized neighbourhood: A longitudinal social network analysis

Abstract In this article we argue that intersectoral collaboration is ultimately manifested at the neighbourhood level, where professionals from diverse sectors engage in a joint network to improve population health outcomes. To strengthen intersectoral collaboration in neighbourhoods with low SES, it is crucial to include the community voice, representing diverse citizens who must be heard and engaged in decision-making processes. This study aims to contribute to the literature of intersectoral collaboration by exploring how networks emerge and evolve over time. We focus on the development of the roles of citizens in the professional network and diverse sectoral involvement within a local network of the team called The Connectors , in a neighbourhood with low socioeconomic scores (SESs). Methodologically, we use a combination of social network analysis (SNA) and action research. Results show that the network expanded significantly over time, both in terms of the number of actors and the diversity of sectors involved. At both measurement points T1 and T2, the majority of collaborations occurred across sectoral boundaries. By the second measurement, the proportion of intersectoral relationships had increased. This indicates that as the network expanded, new collaborations were not confined to existing sectoral clusters but increasingly bridged different sectors. The dual role that citizens have taken on during the development of the network, serving both as community voice representatives and professionals, can be empowering, offering pathways for personal growth and career advancement. However, it also introduces complexity, as these individuals may experience tensions between personal commitments and professional responsibilities. To enable network development, policies should allow room beyond standard protocols and organizational silos, as well as provide sufficient time for relationships and structures to mature. Although network building is a gradual and complex process, once established, these networks can play a pivotal role in delivering integrated and responsive care.
