Community Mobilization Approaches for Large-Scale Public Health Surveys: Experiences from the Population-based HIV Impact Assessment (PHIA) Project.

Community mobilization is an integral process of raising awareness and increasing participation in a specific program. Communities with long-standing mistrust of health research may otherwise be reluctant to participate in surveys originating outside of their locality, particularly when asked to share personal information, provide blood samples, or undergo medical examinations. Here we discuss the community mobilization approaches undertaken by the Population-based HIV Impact Assessment (PHIA) project to optimize participation in surveys across 13 countries of sub-Saharan Africa. The PHIA Project developed a community mobilization strategy to address anticipated community concerns. In each country, a trained cadre of Community Mobilization Coordinators (CMCs) facilitated (1) ongoing communication with leadership and stakeholders at national, provincial/district and local levels; (2) door-to-door visits and group meetings; (3) promotional material dissemination through radio and television jingles and mass social/community media; and (4) the use of public address systems to enhance survey awareness and promote participation. Response rates (RR) were recorded from each survey. The PHIA surveys' mobilization efforts cultivated a receptive environment for data collection. The average household response rate for 13 PHIA surveys was 90.4% and interview RR were consistently over 80%, with women more likely to conduct an interview in all countries except Cote d'Ivoire. 89% of eligible women consented to a blood draw and 81.1% of eligible men consented. The robust and contextualized community mobilization approaches in PHIA were critical for engaging communities in large-scale public health surveys and contributed to high RR in participant interviews and blood draw.
