Introduction: community participation is rapidly being viewed as a requirement for the successful acceptance of health services; it integrates a complicated process which involves customs, beliefs, culture and power relations, not only structures and policies. Yet, there is a wide knowledge gap and changes favouring community participation in primary health care is still minimal. This study aims to assess the process indicators and other factors influencing community participation in the delivery of primary health care.

Methods: this descriptive cross-sectional study using qualitative methods was conducted in Ibadan South East Local Government Area of Oyo State, Nigeria between July and September, 2015. The interview and Focus Group Discussion guides centred around five participation indicators of needs assessment, leadership, resource mobilization, organization and management was used to collect data. A total of 12 in-depth interviews and four FGDs were conducted among male and female respondents consisting PHC service providers and community members purposively selected from four wards of the LGA. Spidergrams were constructed to visualize the levels of community participation from respondents' opinions.

Results: about 51.1% of the 45 respondents (with mean age 45.5 ± 8.09 years) were males. The respondents view community participation in the delivery of PHC in the LGA as being wide (open). Majority of the service users believe and agree that the level of community participation in their wards is about average while the service providers believed that participation was very high. However, respondents identified female representation, collaboration with pre-existing community structures, top-down and bottom-up approach to service delivery as factors affecting community participation in PHC delivery.

Conclusion: this study provides a baseline data on community participation in the delivery of primary health care. Community participation is still an important principle in the delivery of primary health care and it guarantees the positive changes desired in the uptake and sustainability of primary health care programmes.
