Does partnership diversity in intersectoral policymaking matter for health promoting intervention packages' composition? A multiple-case study in the Netherlands

Abstract

Intersectoral policymaking to improve public health includes integrated health promotion (HP) intervention packages that address a variety of health behavior determinants. The involvement of different partners is assumed to be necessary to implement such integrated packages. We examined how partnership diversity was associated with the composition of intervention packages implemented in Dutch municipalities. In a longitudinal multiple-case study (2012-14), we collected questionnaire data among 31 project leaders and 152 intervention implementers in 31 (alliances of) municipalities. Package composition was assessed in terms of intervention strategies, implementation settings and targeted behavioral determinants. Partnership diversity during the adoption and implementation phases was assessed in terms of the actors and sectors, as well as private partners and citizens involved. The association between partnership diversity and package composition was examined using crosstabs. Almost all packages integrated multiple strategies, but mostly education, facilitation and case finding, in multiple, but mostly health and public settings, such as schools. The packages targeted diverse behavioral determinants, although mainly personal and social environmental factors. A variety of partners from multiple sectors was involved, during both adoption and implementation of the packages. However, partners from the health, welfare and education sectors were mostly involved. More partnership diversity, especially during implementation, was associated with more integrated intervention packages. In intersectoral policymaking, investment in diversely composed partnerships seems worthwhile for implementing integrated intervention packages. However, investments in other conditions, like framing health issues and network management, are also needed to make environmental determinants of health behavior the object of HP.
