简要总结
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.
详细描述
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.

研究组 & 干预措施
Parent group that will receive HPV training
Participants assigned to the intervention group received a single, face-to-face, nurse-led educational session based on the Health Belief Model after completion of the baseline assessment. The session lasted approximately 40 minutes and included information on HPV transmission, HPV-related cancers, HPV vaccination, vaccine effectiveness, vaccination schedules, screening, and common misconceptions. Participants were invited to return five weeks later for post-intervention assessment.
干预措施: Behavioral: Health Belief Model-Based HPV Education (Behavioral)
Control group to receive HPV training
Participants assigned to the control group completed the baseline assessment and received no educational intervention during the five-week comparison period. They returned five weeks later for post-intervention assessment. After completion of the post-intervention assessment, they received the same educational session as the intervention group for ethical reasons.
结局指标
主要结局
Human Papillomavirus Knowledge Scale (HPV-KS)
时间窗: Baseline and 5 weeks
HPV knowledge was assessed using the 33-item Human Papillomavirus Knowledge Scale (HPV-KS). The scale includes items assessing general HPV knowledge, HPV testing knowledge, and HPV vaccination knowledge. Items are answered as "Yes," "No," or "I don't know." Each correct response is scored as 1, whereas incorrect and "I don't know" responses are scored as 0. Total scores range from 0 to 33, with higher scores indicating greater HPV-related knowledge.
the human papillomavirus knowledge scale
时间窗: Baseline and 4 weeks
General HPV knowledge", with 16 questions on the subjects' general knowledge of HPV. The second subscale, "HPV testing knowledge", has six items related to HPV screening tests. The third subscale, "HPV vaccine knowledge" consists of seven items regarding HPV vaccine information. "HPV vaccine availability" items, the independent HPV-KS subscale, is organized in three different ways for the HPV vaccine program, which is conducted in three countries (the UK, the US, and Australia) where the scale is applied. The independent subscale can be modified to align with each country's HPV vaccine policy. Participants mark each item of the HPV-KS as "Yes", "No", and "I don't know". In the evaluation phase, each correct answer is scored as "1", and wrong answers and "I don't know" statements are scored as "0". The total HPV-KS score may be between "0 and 35". Higher scores indicate a thorough understanding of HPV general knowledge, HPV screening tests, and the HPV vaccine.
