Preliminary stages of a cross-cultural Brazilian Portuguese adaptation of a measurement tool for assessing public understanding of human papillomavirus

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.

Internal construct validity of the Brazilian version of a tool for assessing the population’s knowledge of human papillomavirus

“…The sample consisted mainly of women (87.6%), and the mean age was 41.3 ± 8.8 years. More details about the sample are available in Manoel et al 15 and Manoel et al 17 .…”

“…This is a cross-sectional study. The 29 items of the cross-culturally adapted Brazilian Portuguese version 15 of the instrument proposed to measure lay knowledge of HPV in English speaking countries 14 were self-administered by 330 adults. The sample comprised parents of 9-15-year-old adolescents, recruited from public and private schools in the municipality of Tubarão, Santa Catarina, Southern Brazil, and community health agents from the same municipality, who had not been previously trained in HPV screening.…”

“…The sample comprised parents of 9-15-year-old adolescents, recruited from public and private schools in the municipality of Tubarão, Santa Catarina, Southern Brazil, and community health agents from the same municipality, who had not been previously trained in HPV screening. The sample was non-probabilistic, as previously described 15,17 .…”

“…Recently, we proposed and published a cross-culturally adapted Brazilian Portuguese version of that tool. The details of the cross-cultural adaptation process can be found in Manoel et al 15 . The preliminary model showed satisfactory reliability; however, the construct validity still needs to be established.…”

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

“…It is also important to note that mostly of these previous studies did not use validated instruments [43][44][45][46][47]54]. This use of a validated instrument is considered a major weakness by Manoel et al [53], who have previously adapted a questionnaire [55] but used a small female sample in one Brazilian city. Although there are different questionnaires to evaluate HPV [23,25,[44][45][46][47][48][49][50][51][52][53][54], we chose the one developed by Saulle et al [25] because it combines sexual behavior, and knowledge about HPV, vaccine and Papanicolaou test in a short interview.…”
