While primary health care programmes based on community participation are widely implemented in low- and middle- income settings, empirical evidence on whether and to what extent local people have the capacity to participate, support and drive such programmes scale up is scant in these countries. This paper assessed the level of community capacity to participate in one such programme - the Community-Based Health Planning and Service (CHPS) in Ghana. The capacity assessments were drawn from Chaskin's (2001) theorised indicators of community capacity with modifications to include: sense of community; community members commitment; community leadership commitment; problem solving mechanisms; and access to resources. These capacity measures guided the design of an interview guide used to collect data from community informants, frontline health providers (FLP) and district health managers. Key qualitative themes were built into a questionnaire administered to households selected through systematic sampling approach. Findings showed that growing individualism, low trust in neighbours and apathetic behaviours undermined the capacity of mutual support for CHPS. The capacity to support CHPS was high for local leadership and community social mobilisation groups who often dedicated time to working with FLP to promote maternal and reproductive health service use, and in advocating broader support for CHPS. Within the wider community, commitment to voluntarism was low as members perceived CHPS to be owned by, and run on government funds and resources. Poor voluntarism was compounded by poverty that crippled the capacity to provide needed resource support for CHPS. Findings have great implications for building strong capable communities for participation in community oriented health programmes.
