Abstract:
This case control retrospective study aimed to identify factors predicting the uptake of Human Papilloma Virus (HPV) vaccine among high school female students in Bangkok Metropolitan area. The concept of Health Belief Model of Becker (1974) was used as a conceptual framework. The sample were divided into 2 groups: 1) a control group consisted of 290 parents of senior high school female students who have not received the HPV vaccine, 2) a study group consisted of 110 parents of senior high school female students who have received the HPV vaccine at least one shot. Five schools were selected. Then 3 classrooms from Mathayom 4, 5 and 6 of each school were randomly selected. The research tool consisted of 7 sets of questionnaires: 1) Personal Information, 2) Influence of HPV vaccine on sexual behavior, 3) Perceived Risk of Cervical Cancer, 4) Perceived on Severity of Cervical Cancer, 5) Perceived Benefits of HPV Vaccine, 6) Perceived on the Barriers to HPV Vaccine, and 7) Estimation of the Uptake of HPV Vaccine. Their content validity were verified by 5 experts and the content validity index were .80, 1.00, .80, 1.00, and 1.00., respectively. Their Cronbachs coefficient alpha were 70, .75, .60, .74 and .70 respectively. Data were respectively analyzed using frequency, percentage, mean, independent t- test and model logistic regression. The findings showed that 3 factors significantly predicted the Human Papilloma Virus vaccine uptake of high school female students in Bangkok Metropolitan area (p < .05). They were perceived severity of cervical cancer (OR = 2.98), perceived benefits of HPV (OR = 2.60), and perceived barriers to HPV vaccine (OR = 0.22). However, perceived risk of cervical cancer (OR = 0.87), influence of HPV vaccine on sexual behavior (OR = 0.87), and education level of parents (OR = 1.36) could not significantly predict the uptake of HPV vaccine. Logistic regression equation can significantly predict the uptake of HPV vaccine at 32.70 % and predict the non-uptake at 93.40 %, resulting in the correct prediction 76.80 %
