A Video-Based Behavioral Intervention Associated with Improved HPV Knowledge and Intention to Vaccinate

Area of Science:

• Public Health
• Behavioral Science
• Vaccinology

Background:

• Human papillomavirus (HPV) infection is a significant public health concern.
• Low HPV vaccine uptake necessitates effective interventions to improve knowledge and intent.
• Parent-daughter communication plays a crucial role in adolescent vaccination decisions.

Purpose of the Study:

• To design, develop, and assess the feasibility of a theory- and evidence-based online intervention.
• To enhance human papillomavirus (HPV) and HPV vaccine knowledge among parent-daughter dyads.
• To increase the intention to vaccinate against HPV within these dyads.

Main Methods:

• A prospective, randomized, controlled feasibility trial was conducted.
• An online behavioral intervention, "Is the HPV vaccine for me?", was developed.
• Knowledge, vaccination intention, and intervention feasibility were evaluated in 49 parent-daughter dyads.

Main Results:

• The intervention group showed a statistically significant increase in HPV and HPV vaccine knowledge compared to the control group.
• Intention to vaccinate against HPV significantly increased in the intervention group.
• The intervention was found to be useful (96% of participants), interesting, effective, safe, and acceptable.

Conclusions:

• The developed online intervention is a feasible, effective, and acceptable tool for improving HPV and HPV vaccine knowledge.
• The intervention successfully increased the intention to vaccinate among parent-daughter dyads.
• This approach holds promise for future public health strategies aimed at increasing HPV vaccination rates.
