This paper reports on a qualitative study exploring the capacity of the community sector to support a whole-of-system response to cardiovascular disease prevention in primary health care. As a component of the Model for Prevention (MoFoP) study, community-based lifestyle modification providers were recruited in the Australian Capital Territory to participate in focus group discussions; 34 providers participated across six focus groups: 20 Allied Health Professionals (four groups) and 14 Lifestyle Modification Program providers (two groups). Thematic analysis of focus group transcripts was undertaken using a mixed deductive and inductive approach. Participant responses highlight several barriers to their greater contribution to cardiovascular disease prevention. These included that prevention activities are not valued, limited sector linkages, inadequate funding models and the difficulty of behaviour change. Findings suggest that improvements in the value proposition of prevention for all stakeholders would be supported by improved funding mechanisms and increased opportunities to build relationships across health and community sectors.
