Promoting Rural-Residing Parents' Receptivity to HPV Vaccination: Targeting Messages and Mobile Clinic Implementation.

Interventions are needed to increase low HPV vaccination rates within rural areas in the United States, particularly in the state of Florida, which has the seventh highest number of HPV-related cancers. Florida also ranks low compared to other states in terms of HPV vaccination. Rural-residing parents may benefit from two evidence-based strategies to increase vaccination rates: reminder messages informing and prompting vaccination appointments and mobile clinics to reduce transportation barriers. We sought to identify parental attitudes towards (1) message features that promote rural-residing parents' receptivity to HPV vaccination; (2) parents' acceptability of three reminder message modalities (text, postcard, phone); and (3) implementation factors that promote parents' acceptability of using a mobile clinic for vaccination. We recruited 28 rural-residing parents of 9- to 12-year-old children (unvaccinated for HPV) for focus group and individual interviews and thematically analyzed transcripts. Three features promoted parents' receptivity to HPV vaccination messages: source credibility , specific information coverage , and personalization (name and birthday wishes) . Parents most preferred text messages and identified three factors promoting parents' mobile clinic use: convenience and feasibility, trustworthiness, and detailed information . The findings indicate rural-residing parents' acceptability of reminder messages and mobile clinics as well as the importance of trust and feasibility when implementing these evidence-based strategies for rural-residing parents.
