Abstract

The objective of this study was to conduct the initial stages of the cross-cultural adaptation to Brazilian Portuguese of a scale to measure the level of knowledge about HPV. The stages included: translation from English into the Portuguese spoken in Brazil; synthesis of the translated version; back-translation; analysis by an expert committee; and reliability analysis based on internal consistency and reproducibility. Cronbach's α coefficient for the instrument was 0.985. Subset analysis produced only minor variations. The correlation coefficients between the individual items and the overall result showed strong positive correlations, except for three items. Reproducibility analysis showed kappa values with substantial or moderate agreement for the majority of the items. A preliminary Brazilian version was obtained with satisfactory results, but other stages are necessary in the process of validation of the Brazilian version.

Highlights

The human papillomavirus (HPV) is one of the main viruses that cause cancer, especially cervical cancer 1.The Brazilian Federal government launched an HPV immunization campaign in 2014 (Brazilian Ministry of Health. http://pni.datasus.gov. br/consulta_hpv_14_C01.php)
Waller et al 2 developed a scale to measure the level of knowledge on HPV, the only validated tool for this purpose
Since public understanding of HPV vaccination can play a key role in the success of this preventive measure by the Brazilian public health system, the current study developed the preliminary stages of cross-cultural adaptation of a measure of knowledge and awareness about HPV, previously validated in English 2

Summary

Introduction

The human papillomavirus (HPV) is one of the main viruses that cause cancer, especially cervical cancer 1.The Brazilian Federal government launched an HPV immunization campaign in 2014 (Brazilian Ministry of Health. http://pni.datasus.gov. br/consulta_hpv_14_C01.php). The human papillomavirus (HPV) is one of the main viruses that cause cancer, especially cervical cancer 1. The Brazilian Federal government launched an HPV immunization campaign in 2014 The campaign has raised social and ethical discussions on the fact that vaccination against a sexually transmitted virus is being targeted to young girls. Lack of the population’s knowledge on HPV may explain some parents’ reluctance to have their daughters vaccinated. Waller et al 2 developed a scale to measure the level of knowledge on HPV, the only validated tool for this purpose. The “Measure of Knowledge about HPV” consists of 29 statements divided into three subscales, one on HPV, one on the vaccine, and the last on the HPV test. Interviewees are asked to check “true”, “false”, or “I don’t know” for each of the statements
