The Impact of Health Narratives on Persuasion in African American Women: A Systematic Review and Meta-Analysis.

African American women (AAW) experience higher burdens of disease and have the highest rate of heart disease, cancer, stroke, and diabetes when compared to females of other ethnic groups. Health narratives are a communication strategy that has been used to improve population health outcomes. Narrative storytelling is considered to be effective for improving health outcomes in African Americans because of the strong cultural storytelling background. The purpose of this study was to determine if health narratives have a significant effect on persuasion among AAW, as measured by changes in attitudes, beliefs, intentions, and behaviors. Meta-analysis of health narrative experiments (k = 13) for AAW (N = 2,746) revealed that health narratives have a significant overall effect on persuasion (d = .243; p < .01). Sub-group analyses revealed no significant difference between audio-visual and written-based narratives, and no significant difference between general health topics and cancer topics. Narrative communication was effective for promoting health in AAW. These findings imply that narratives can effectively be used as an audio-visual or written-based communication for AAW, and that health topic may not impact outcomes of narrative communication.
