Although there is evidence of increasing childbirth in internally displaced person (IDP) camps, limited literature exists on how to promote knowledge and use of modern family planning methods among this vulnerable group. The objective of this study was to determine the efficacy of visual multimedia in promoting knowledge and use of modern family planning methods among families in IDP camps in Nigeria. This study was a quasi-experiment of 470 individuals in IDP camps to determine the impact of visual multimedia in enhancing knowledge and intention to use modern family planning. The result of the study showed that at the pre-stage, participants in both the control and treatment groups reported low scores on knowledge and use of modern family planning methods. After the intervention and follow-up assessment, participants in the experimental group reported higher mean scores regarding knowledge and intention to use modern family planning methods while participants in the control group did not significantly improve. Animated visuals were found to be more effective than static pictures.
