| Summary: | The aim of this research was twofold: (1) develop an instrument to assess knowledge regarding human papillomavirus (HPV) and its vaccine and utilize this instrument to measure knowledge levels of Greek adolescents in Lyceum schools of Western Thessaloniki; and (2) examine the associations of the resultant knowledge measure scores with sociodemographic characteristics.
Cross-sectional survey with complex sampling design.
A total of 268 students of three Lyceum schools in Western Thessaloniki responded anonymously to a questionnaire during February–March 2013. The instrument was developed by literature review. Answers of respondents to individual questions were initially presented in terms of absolute and relative frequencies. Knowledge items were presented by gender along with appropriate chi-squared tests. Next, the development and validation of a knowledge score was pursued with Rasch analysis. Raw scores of dichotomous true/false items were converted to interval-level adjusted student scores, and the reliability and validity of the model were assessed. Finally, the effect of sociodemographic variables on the knowledge measure was explored by multivariate linear regression.
Analysis of individual items documented low knowledge for both female and male students along with a limited role of doctors as information agents and little associated encouragement toward vaccination. Vaccine uptake was low with many young girls being largely unwilling to vaccinate in the future primarily due to the fear of side-effects and lack of information. Person location parameters (knowledge scores) were derived from a Rasch model with satisfactory reliability and validity. The resultant validated measure confirmed the low knowledge levels of Greek students. Nationality and birthplace seemed to affect knowledge level.
Further improvement and validation of the knowledge measure used in this study can assist nationwide surveys in order to examine student knowledge regarding HPV and its vaccine. Our findings also stress the exacerbated need for effective nationwide educational campaigns aiming to inform adolescents about HPV and the associated vaccine. Appropriate incentives should also be given to physicians to increase their involvement. Parents and students should be thoroughly informed about the value of research similar to ours, in order to increase survey participation rates.
•There is low knowledge on human papillomavirus among adolescents in Western Thessaloniki.•Nationality and birthplace might affect adolescent knowledge.•Vaccination intake is low due to the fear of side-effects and lack of information.•Doctors have a limited role as information agents and do not promote vaccination. |
