NCT01729429

Brief Summary

This randomized controlled trial is designed to evaluate whether a behavioral intervention that includes three components: 1) reminder letters and education materials delivered before the clinic visit, 2) telephone recalls after the visit for those who originally decline the vaccine, and 3) telephone reminders for those who miss the 2nd and/or 3rd doses, increases 1 and 3 dose coverage of the human papillomavirus (HPV) vaccine series among adolescent girls attending four Parkland primary care clinics in Dallas county. Hypothesis 1: Investigators expect higher 1 dose HPV vaccine coverage among patients in the Intervention group than those in the General Adolescent Vaccine Brochure group. Hypothesis 2: Investigators expect significantly higher 1 dose HPV vaccine coverage among patients in the Intervention group who initially declined the vaccine than those in the General Adolescent Vaccine Brochure group who initially declined. Hypothesis 3: Investigators expect significantly higher 3 dose HPV vaccine coverage among the Intervention group than those in the General Adolescent Vaccine Brochure group.
