Abstract:
This descriptive predictive research aimed at identifying significant predictors of human papillomavirus vaccination intention among men who have sex with men (MSM) receiving sexual health services from five factors: HPV knowledge, outcome expectations, self - efficacy to get HPV vaccine, self - control to get HPV vaccine and situational perception. Subjects were 140 MSM who came to receiving sexual health services from 3 places in Bangkok using convenience sampling technique. Data were collected using HPV knowledge questionnaire, outcome expectations questionnaire, self - control to get HPV vaccine questionnaire, situational perception questionnaire, self - efficacy to get HPV vaccine questionnaire, and the intention to take HPV vaccine questionnaire. The questionnaires were tested for their content validity by a panel of experts. Their CVIs were 1.00, .87, 1.00, 1.00, 1.00, and 1.00, respectively. Their KR-20 =.82 and Cronbachs alpha coefficients were .81, .81, .94, .94, and .90, respectively. Data were analyzed using stepwise multiple regression. The results revealed that: 1) The mean score of intention to take HPV vaccine was at high level (mean=11.39, SD=2.39). 2) Self - efficacy to get HPV vaccine (Beta=.419), situational perception (Beta=.231), and HPV knowledge (Beta=.148) were significant predictors of intention to take HPV vaccine among MSM receiving sexual health services. These significant predictive variables accounted for 40.1% of the total variance in intention to take HPV vaccine (p<.05). However, outcome expectations and self - control to get HPV vaccine could not significantly predict intention to take HPV vaccine (p>.05).
