Resumo: To analyze the efficacy and psychometric properties of the Knowledge, Attitudes, and Practices Questionnaire when applied to adolescents. It was a cross-sectional construct validation study. Ten questions on the knowledge of HIV/AIDS were selected from the questionnaire for further data analysis and applied to 623 adolescents attending high school. The Statistical Package for the Social Sciences (SPSS) 25.0™ and Stata 14.0 software processed the data. Cronbach's Alpha verified the reliability of items, and the mean of each value ranged from 0.198 to 0.379. Factor analysis assessed the structure of correlations between variables. The resulting factors were lifestyle/habits, preventive actions, and endogenous and exogenous transmission. The scale was reliable for the studied population, ensuring the quality of the instrument.

Métodos: Tratou-se de um estudo transversal de validação de constructo. Foram selecionadas 10 perguntas do questionário supracitado, referentes ao conhecimento sobre HIV/aids, para posterior análise dos dados, o qual foi aplicado em 623 adolescentes que estavam cursando o ensino médio. O tratamento dos dados foi realizado no Statistical Package for the Social Sciences (SPSS) 25.0® e pelo Stata 14.0. Resultados: A confiabilidade dos itens foi averiguada por meio do Alfa de Cronbach, onde a média de cada valor variou de 0,198 a 0,379. Também foi realizada análise fatorial para analisar a estrutura das correlações entre as variáveis. Os fatores resultantes foram: Estilo de vida/hábitos, atitudes preventivas, formas de transmissão endógenas e formas de transmissão exógenas. Conclusão: Constatou-se a confiabilidade da escala na população estudada, assegurando a qualidade do instrumento.Universidade Federal de Uberlândia2023-02-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/6273510.14393/BJ-v39n0a2023-62735Bioscience Journal ; Vol. 39 (2023): Continuous Publication; e39042Bioscience Journal ; v. 39 (2023): Continuous Publication; e390421981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/62735/35634Brazil; Contemporary Copyright (c) 2023 Jéssica Kelly Ramos Cordeiro, Waleska Fernanda Souto Nóbrega, Milena Edite Casé de Oliveira, Kedma Anne Lima Gomes, Tiago Almeida de Oliveira, Ângelo Giuseppe Roncalli da Costa Oliveirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCordeiro, Jéssica Kelly Ramos Nóbrega, Waleska Fernanda SoutoOliveira, Milena Edite Casé de Gomes, Kedma Anne LimaOliveira, Tiago Almeida de Oliveira, Ângelo Giuseppe Roncalli da Costa2024-01-31T19:16:18Zoai:ojs.www.seer.ufu.br:article/62735Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2024-01-31T19:16:18Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
