The effect of school-based cervical cancer education on perceptions towards human papillomavirus vaccination among Hong Kong Chinese adolescent girls

Abstract

Objective: To evaluate the effects of school-based cervical cancer education on Hong Kong Chinese adolescent girls.

Methods: Adolescent girls (n=953) in local secondary schools attended a tailored educational program on cervical cancer prevention. Self-administered questionnaires were used before and after the program to measure its effects on participants' knowledge, attitude and perceived social norms towards human papillomavirus (HPV) vaccination and their intention to be HPV vaccinated.

Results: Before the program, HPV vaccine acceptance was favorable but relevant knowledge was low. After the program, participants had greater knowledge and a more positive attitude (both p<0.001), with more girls anticipating family (41.6% before vs. 58.9% after) and peer support (32.8% before vs. 56.9% after). There were 11.3% more girls who indicated an intention to accept the vaccine afterward. More knowledge, a more positive attitude and perceived support from significant others predicted a stronger intention to be HPV vaccinated.

Conclusion: The educational program had a positive impact on participants' perceptions towards HPV vaccination and their intention to be vaccinated.

Practice implications: School-based cervical cancer education is a viable means to meet the substantial educational needs of adolescents. Promotion of HPV vaccination should also include educating and influencing perceptions of families and peers.
