Trusted Messengers, Uncertain Effects: Opinion Leaders and Rural Health Campaigns in Nigeria

Abstract

Health campaigns in rural communities frequently depend on respected intermediaries, but favourable perceptions of those intermediaries cannot alone demonstrate behavioural effects. This study examined opinion leadership in campaigns concerning malaria prevention, immunisation and sanitation across six rural communities in Delta State, Nigeria. The dissertation reports a mixed-methods survey comprising 380 returned questionnaires from 384 distributed and six interviews with community opinion leaders. Descriptive assessments indicated perceived exposure to campaigns (grand mean 3.11 on a four-point scale), opinion-leader involvement (3.25), positive health-related practices (3.18), perceived leader influence (3.27), and favourable evaluations of leaders’ participation (3.29). Religious leaders were most prominently identified (mean 3.32). Interview accounts described interpersonal explanation, mobilisation and local authorisation as prominent mechanisms, while also acknowledging uneven access among remote residents. However, the dissertation’s correlation tests used four aggregated item means rather than participant-level observations and do not provide valid evidence of individual-level associations. The study therefore supports a qualified conclusion: rural opinion leaders are perceived as trusted conduits for campaign communication, but the extent to which their participation changes health behaviour remains unestablished. Future programmes should involve diverse community representatives at the design stage and evaluate outcomes using respondent-level or prospective measures.
