Vax Facts HPV: Study of a Computer-based Tailoring System and Mothers' Intentions to Vaccinate Their Daughters Against HPV

This will be a randomized controlled intervention trial for HPV vaccine-hesitant mothers of
adolescent (ages 11-15 years old) girls. Mothers will complete a three-item measure that
assesses their baseline intentions for having their adolescent daughter vaccinated against
HPV. Mothers will then fill out a short, computer-based survey that assesses demographic
factors, prior experience with HPV-associated illnesses and views about a variety of
potential barriers to HPV vaccination. Following the survey, the intervention group (40
mothers) will receive a two-page print brochure that uses their survey data to generate the
brochure such that it addresses each mother's top three concerns about the HPV vaccine. The
control group (40 mothers) will receive a generic, two-page brochure that is similar in
appearance to the intervention, but contains only untailored, generic information about the
vaccine. HPV vaccination intention will be assessed a second time after reading the
brochure, using the same three-item measure as before the survey. The vaccine administration
records of the adolescent daughters of these mothers will be accessed three months after
mothers' participation in the study to assess whether any HPV vaccine doses were provided.

Inclusion Criteria:

- Mother is greater than or equal to 18 years of age

- Mother has a daughter who is between the ages of 11-15 years

- Daughter has not received any doses of the HPV vaccine

- When asked to describe how she feels about getting her daughter vaccinated against
HPV in the next six months, mother responds "I don't want her to get vaccinated" or
"I'm unsure if I want her vaccinated."

Exclusion Criteria:

- Cannot read/speak English
