In the United States, a low (32%) female vaccination rate limits population-based benefits of human papillomavirus (HPV) vaccination. The purpose of this study was to evaluate whether multimodal counseling interventions increased HPV vaccination series non-completers' knowledge of HPV-attributable disease and HPV-attributable disease prophylaxis (vaccination) acceptance, over a control 14-sentence counseling intervention.


A single-blind, quantitative, four-group, simple randomization, pretest-posttest online study with a minimum of 260 participants per group, was conducted in February 2015. Experimental Group 1 viewed an audiovisual presentation, Experimental Group 2 read a public health education handout (PHEH), and Experimental Group 3 viewed the audiovisual and read the PHEH. Knowledge of HPV and HPV vaccination acceptance was indicated by agree or strongly agree responses to 11 knowledge and 14 acceptance items.


Compared to the control group, all experimental groups showed a greater increase in HPV-attributable disease and HPV vaccination knowledge, P=.038. The PHEH intervention, and combined audiovisual and PHEH intervention, raised knowledge of HPV-attributable external genital warts (EGW), P<.001. The combined audiovisual and PHEH intervention raised knowledge of HPV vaccination purpose, P=.02. The combined PHEH and audiovisual achieved increased HPV vaccination acceptance for seven items, P<.001 to P=.023. The audiovisual intervention achieved increased HPV vaccination acceptance for five items, P<.001 to P=.006.


That HPV causes EGW, and that HPV vaccination prevents HPV-attributable diseases were better conveyed by the combined audiovisual and PHEH than the control 14-sentence counseling intervention alone.
