Evaluating Now I Know mHealth intervention promoting HPV vaccine completion among young women attending federally supported clinics

Résumé fourni par la source

PURPOSE: This study evaluated the feasibility, acceptability, usability, and HPV vaccine completion rate of the Now I Know (NIK) mHealth intervention to promote HPV vaccine completion among minority and low-income young women. METHODS: This quasi-experimental pilot study recruited 35 women aged 18-26 at two federally supported outpatient clinics in a large city in the Northeastern United States. Participants were allocated to two groups: 24 received the NIK intervention plus usual care and 11 received usual care only. After completing a baseline assessment, intervention group participants launched the NIK mobile app, which entailed HPV vaccine education, self-managed vaccine record & reminder, and Q&A features. Follow-up visits were conducted at 2 and 6 months. Feasibility was assessed through screening, recruitment, fidelity, and retention. Acceptability and usability were evaluated via survey and exit interview. The primary outcome-HPV vaccine 3-dose series completion-was analyzed using descriptive statistics. RESULTS: This study demonstrated feasibility by reaching the recruitment target (n = 35) and high retention rate (89%). Participants reported the app was acceptable, appreciating reliable information, convenient access, providing a personal touch, and raising awareness. Regarding usability, users found the app easy to navigate, accessible, well organized, and user-friendly. The HPV vaccine completion rate was higher in the intervention group (55%) than in the usual care group (45.5%). CONCLUSION: Findings showed improved vaccination completion among those using the Now I Know mHealth intervention (compared to usual care), acceptability of the intervention, and feasibility of recruiting, retaining, and delivering the intervention to promote HPV vaccine completion among young women in federally subsidized healthcare settings.
