Abstract(s)
Enquadramento: A promoção da gestão do regime terapêutico em pessoas com doença crónica, requer
medidas fiáveis e válidas, para avaliação da motivação para o tratamento.
Objetivo: Avaliar as propriedades psicométricas da versão portuguesa do Questionário de Autorregulação
(QAR) para o tratamento medicamentoso, numa amostra de pessoas com doença crónica.
Metodologia: Estudo metodológico, com recurso à análise fatorial confirmatória (AFC). Participaram
189 pessoas com doença crónica.
Resultados: A solução trifatorial do QAR não mostrou bom ajustamento ao modelo, pelo que é
proposta uma solução de quatro fatores. A AFC mostrou um ajuste muito satisfatório nos índices
de adequação do modelo. A validade convergente foi confirmada por associações entre a motivação
autónoma, competência percebida e perceção de um ambiente terapêutico promotor da autonomia, e
com a adesão aos medicamentos. A análise de confiabilidade mostrou valores de consistência interna
que variam entre 0,56 e 0,90.
Conclusão: O instrumento demonstra ser uma medida fiável e válida para a avaliação da autorregulação
ao tratamento medicamentoso em pessoas com doença crónica.
Background: The promotion of the management of the therapeutic regimen in people with chronic disease implies reliable and valid measures to assess motivation for treatment. Objective: To assess the psychometric properties of the Portuguese version of the Self-Regulation Questionnaire (SRQ) of the medication treatment in a sample of people with chronic disease. Methodology: A methodological study was conducted using the Confirmatory Factor Analysis (CFA). The sample was comprised of 189 people with chronic disease. Results: A three-factor solution of the SRQ showed poor fit to the model, thus a four-factor solution was suggested. The convergent validity was confirmed by associations between autonomous motivation, perceived competence and perception of a therapeutic environment that promotes autonomy, and adherence to medication. The reliability analysis showed satisfactory internal consistency values ranging between 0.56 and 0.90. Conclusion: The instrument shows good reliability and validity to assess self-regulation of the treatment regimen in people with chronic disease.
