Contexto: O reconhecimento da qualidade dos instrumentos que procuram verificar e avaliar um fenómeno através do processo de validação de conteúdo, é fundamental para a legitimidade e credibilidade dos resultados de uma pesquisa. Objetivos: Investigar a aplicação do modelo de validação de conteúdo de Pasquali nas pesquisas brasileiras em Enfermagem nos últimos cinco anos. Metodologia: Revisão integrativa de literatura realizada no período de julho a agosto de 2013, nas bases de dados Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Base de Dados de Enfermagem (BDENF), com uso de descritores controlados e não-controlados. Resultados: Os estudos adotaram o referencial metodológico de Pasquali baseados nos três procedimentos (teóricos, empíricos e analíticos), que exigiu o cumprimento de etapas, tais como construção do instrumento, parecer dos juízes e aplicação de procedimentos estatísticos para a validação de conteúdo. Conclusão: O processo de validação de conteúdo ocorreu no procedimento teórico e houve associação a outros tipos de validação para percorrer os procedimentos empíricos e analíticos, a fim de alcançar uma validação eficaz. Palabras clave: estudios de validación; investigación en enfermería; enfermería. Background: The recognition of the quality of instruments that aim at verifying and assessing a given phenomenon, through the process of content validation, is essential for the legitimacy and credibility of research results. Objectives: To analyse the application of the Pasquali's model of content validation to Brazilian research studies in the Nursing field conducted over the past five years. Methodology: Integrative literature review performed between July and August, 2013, using the Latin American and Caribbean Health Sciences Literature database (LILACS) and Nursing Database (BDENF), with controlled and uncontrolled descriptors. Results: The studies adopted the Pasquali's methodological reference model based on three procedures (theoretical, empirical, and analytical). This required the completion of different steps, such as the construction of the instrument, feedback from judges and application of statistical procedures for content validation. Conclusion: The process of content validation occurred during the theoretical procedure, in association with other types of validation to comply with the empirical and analytical procedures and achieve an effective validation.

Objective: to describe the content validation process of a Virtual Learning Object to support the teaching of nursing care systematization to nursing professionals. Method: methodological study, with quantitative approach, developed according to the methodological reference of Pasquali's psychometry and conducted from March to July 2016, from two-stage Delphi procedure. Results: in the Delphi 1 stage, eight judges evaluated the Virtual Object; in Delphi 2 stage, seven judges evaluated it. The seven screens of the Virtual Object were analyzed as to the suitability of its contents. The Virtual Learning Object to support the teaching of nursing care systematization was considered valid in its content, with a Total Content Validity Coefficient of 0.96. Conclusion: it is expected that the Virtual Object can support the teaching of nursing care systematization in light of appropriate and effective pedagogical approaches.
