Measuring impact of storyline engagement on health knowledge, attitudes, and norms: A digital evaluation of an online health-focused serial drama in West Africa.

BACKGROUND

"Cest la Vie!" (CLV) is a serial drama that entertains, educates, and promotes positive health behaviors and social change for West African audiences. The purpose of this study was to evaluate if watching the CLV Season 2 series online had an impact on people's health knowledge, attitudes, and norms, focusing on populations in francophone West Africa.

METHODS

Between July 2019 and October 2019, viewers of CLV and non-viewers were recruited from Facebook and YouTube. We conducted an online longitudinal cohort study that assessed changes in health knowledge, attitudes, and norms (KAN) between these groups. Participants completed a baseline survey prior to the online airing and up to three follow-up surveys corresponding to specific health stories in the series, including sexual violence, emergency contraception, and female circumcision. We used descriptive statistics to describe viewers and non-viewers, and an item response theory (IRT) analysis to identify the effect of viewing CLV on overall KAN.

RESULTS

A total of 1674 respondents participated in the study. One in four participants (23%, n = 388) had seen one of the three storylines from CLV Season 2 (ie, CLV viewers). At follow-up, viewers were more likely than non-viewers to know when to correctly use emergency contraception (P < 0.001) and to believe that the practice of female circumcision should end (P = 0.001). Compared to people who did not see CLV, viewers of the series had 26% greater odds of answering pro-health responses at follow-up about sexual assault, emergency contraception, and female circumcision. Further, the level of engagement with specific storylines was associated with a differential impact on overall outcome questions.

CONCLUSIONS

As internet access continues to grow across the globe and health education materials are created and adapted for new media environments, our study provides a novel approach to examining the impact of online entertainment-education content on health knowledge, attitudes, and norms.
