The Perceived Barriers to Antiretroviral Therapy Adherence (PEDIA) scale was developed based on individual interviews with patients. After pilot testing and assessing the evidence based on content analysis, the scale’s revisions resulted in a 40-item version. The PEDIA was applied to 415 HIV-infected adults receiving ART for a maximum of 180 days, recruited from three healthcare facilities of reference in the city of Belo Horizonte, Minas Gerais State, Brazil. The analyses included exploratory factor analysis, internal consistency, item response theory, temporal stability, and predictive test-criterion relationship. The scale’s final version contains 18 items distributed in three dimensions, as follows: cognitive and routine problems (4 items); medication and health concerns (6 items); and patient’s fears and feelings (8 items). The results of McDonald’s omega and temporal stability demonstrate that the PEDIA is internally consistent and yields stable scores over time. The assessment of the information’s functions suggested that the three dimensions were informative for assessing a broad range of latent traits. Evidence concerning the test-criterion relationship confirmed that the PEDIA was able to predict non-adherence three months later. Our findings suggest that the PEDIA is a psychometrically adequate tool for evaluating perceived barriers in adult patients initiating ART. It could be used in both research and clinical practice for the early detection of patients at risk of non-adherence and for the identification of potentially modifiable barriers.Este estudo teve por objetivo o desenvolvimento e avaliação de uma nova medida de desfecho relatada pelo paciente para avaliar barreiras percebidas à adesão à terapia antirretroviral (TARV). A escala Percepção de Dificuldades com o Tratamento Antirretroviral (PEDIA) foi desenvolvida com base em entrevistas com pacientes. Após teste piloto e avaliação de evidências com base no conteúdo do teste, revisões da escala resultaram em uma versão com 40 itens. A PEDIA foi aplicada em 415 adultos soropositivos para HIV que receberam TARV por um máximo de 180 dias, recrutados de três unidades de saúde de referência na cidade de Belo Horizonte, Minas Gerais, Brasil. As análises incluíram análise fatorial exploratória, consistência interna, teoria da resposta ao item, estabilidade temporal, e relação preditiva teste-critério. A versão final da escala contém 18 itens distribuídos em três dimensões, no caso: problemas cognitivos e de rotina (4 itens); preocupações com medicamentos e saúde (6 itens); e medos e sentimentos do paciente (8 itens). Resultados do ômega de McDonald e estabilidade temporal demonstram que a PEDIA é internamente consistente e produz escores estáveis ao longo do tempo. As funções de informação do teste sugerem que as três dimensões foram informativas na avaliação de uma ampla gama do traço latente. Evidências relacionadas à relação teste-critério confirmaram que a PEDIA foi capaz de prever não-adesão três meses depois. Nossos resultados sugerem que a PEDIA é uma ferramenta robusta do ponto de vista psicométrico para a avaliação das barreiras percebidas por pacientes adultos que iniciam TARV. Ela pode ser usada em contextos clínicos e de pesquisa para a detecção precoce de pacientes em risco de não-adesão e para a identificação de barreiras potencialmente modificáveis.FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisengUniversidade Federal de Minas GeraisUFMGBrasilFAF - DEPARTAMENTO DE PSICOLOGIAFAR - DEPARTAMENTO DE FARMÁCIA SOCIALMED - DEPARTAMENTO DE MEDICINA PREVENTIVA SOCIALCadernos de Saúde PúblicaMedidas de resultados relatados pelo pacientePsicometriaInfecções por HIVAdesão à medicaçãoPatient reported outcome measuresPsychometricsHIV infectionsMedication adherenceNew patient-reported outcome measure to assess perceived barriers to antiretroviral therapy adherence: the PEDIA scaleUma nova medida de desfecho relatada pelo paciente para avaliar barreiras percebidas à adesão à terapia antirretroviral: a escala PEDIAinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scielo.br/j/csp/a/RwFf79RxVSFJXP7yfdJvSFk/?lang=en#Celline Cardoso Almeida-BrasilElizabeth do NascimentoMicheline Rosa SilveiraPalmira de Fátima BonoloMaria Das Graças Braga Ceccatoapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
