Collaborating in a penta-helix structure within a community based participatory research programme: 'Wrestling with hierarchies and getting caught in isolated downpipes'.

The main issue uncovered in this study is the problem of vertically organised institutions where discovery and innovation processes flow down from the top, thereby eliminating the essential input of the people and community that they are supposed to serve. The success of the programme was based on an interprofessional cooperation at a local level, where local professions worked together with voluntary organisations, social workers, CBPR researchers from the university, citizens and local health promoters.
