Human papillomavirus knowledge, beliefs, and behaviors : a questionnaire adaptation

Abstract

Objective: This study aims to adapt a questionnaire about the knowledge, beliefs and behaviors regarding HPV and related subjects into Brazilian Portuguese. Study Design: National Survey. Methods: The instrument was translated into Portuguese and retranslated into English separately. Experts assessed the validity of the content and cross-cultural adaptation of the instrument. The instrument was administered to 8580 male and female Brazilian adolescents and young adults (aged between 16 and 25 years) who participated in the National Survey of Human Papillomavirus Prevalence (POP-Brazil). This large-scale survey enrolled participants from 26 Brazilian capitals and the Federal District. Results: The full questionnaire is composed of 30 questions, with a good absolute agreement between its two halves (61.16 9.97). The preventive behavior section showed the lowest agreement. Men and women showed a difference concerning their knowledge about HPV (score for men 0.48 ( 8.93) vs. women 0.55 ( 4.51), p < 0.001). Conclusion: The proposed questionnaire is the first instrument able to describe the knowledge, beliefs and behaviors regarding HPV and related subjects in Brazilian women and men. This questionnaire appears to be adequate for use in future studies that may produce evidence and knowledge on these specific topics.
