Abstract

INTRODUCTION:

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.

METHODS:

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.

RESULTS:

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.

CONCLUSION:

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.
