Parent Education About Human Papillomavirus (HPV)

Overview

Human papillomavirus (HPV) vaccination is an effective strategy for preventing HPV-related diseases; however, parental knowledge and vaccination intention may influence vaccine uptake among children and adolescents. This randomized controlled trial evaluated the effect of a Health Belief Model (HBM)-based parent education intervention on HPV knowledge and HPV vaccination intention among parents of children aged 9-14 years. A total of 64 parents were enrolled and randomly assigned to an intervention group (n=32) or a control group (n=32). Following baseline assessment, the intervention group received a single, approximately 40-minute, face-to-face, nurse-led educational session based on the constructs of the Health Belief Model. The control group received no educational intervention during the five-week comparison period. HPV knowledge and vaccination intention were assessed at baseline and five weeks later. After completion of the five-week assessment, the control group received the same educational session for ethical reasons.

This parallel-group randomized controlled trial was conducted among parents of children aged 9-14 years. A total of 64 eligible parents completed the baseline assessment and were allocated to two parallel groups, with 32 participants in the intervention group and 32 participants in the control group. Following the baseline assessment, participants assigned to the intervention group received a single, face-to-face, nurse-led educational session based on the Health Belief Model. The approximately 40-minute session addressed HPV transmission, HPV-related diseases and cancers, HPV vaccination, vaccine effectiveness, recommended vaccination schedules, screening, common misconceptions, and barriers to vaccination. The educational content was structured according to the Health Belief Model constructs of perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy. Participants in both groups were invited to return five weeks after the baseline assessment. To reduce interaction between groups during follow-up assessment, the intervention and control groups attended at different times on the same day. The intervention group attended first, followed by the control group. HPV knowledge and vaccination intention were reassessed at the five-week follow-up. All 32 participants in the intervention group completed the follow-up assessment. Of the 32 participants assigned to the control group, 30 completed the follow-up assessment. After completion of the follow-up assessment, participants in the control group received the same educational session provided to the intervention group.
