Resumo
Objetivo: Discutir a relação entre teorias de mensuração, modelos psicométricos e validade, destacando implicações para instrumentos utilizados em saúde e enfermagem. Método: Artigo de reflexão teórico-conceitual, orientado por crítica da literatura sobre medida, psicometria e validade. Desenvolvimento: A discussão diferencia quantificar, mensurar, modelar estatisticamente e validar interpretações de escores; analisa críticas à quantificação acrítica; e aproxima teorias de mensuração, modelos psicométricos e abordagens contemporâneas de problemas como dor, autocuidado, adesão terapêutica, segurança do paciente, competências clínicas e qualidade de vida. Conclusão: A validade depende da coerência entre a natureza do construto, a lógica de mensuração, o modelo psicométrico, as evidências produzidas, o contexto de uso e as consequências das decisões baseadas nos escores.
