Evidence of content validity of the nursing diagnosis risk for unstable blood pressure

PurposeTo analyze evidence of content validity of the nursing diagnosis (ND) Risk for Unstable Blood Pressure in incarcerated women. MethodA methodological study assessing the content validity of an ND, was performed in Brazil, between June and September 2022, with 49 nurses as experts. The label, definition, and relevance of the 19 risk factors of the ND Risk for Unstable Blood Pressure were appraised. Based on the predictive diversity model, the content validity index (CVI) and respective 95% confidence intervals were calculated for each risk factor. A CVI >= 0.8 was considered adequate evidence of content validity.FindingsThe label and the definition of the diagnosis was reformulated. The relevance of 19 etiological factors showed a CVI >= 0.8. According to the recommendation of the panel of experts, one of the etiological factors was split in two and two label of etiological factors were changed.ConclusionsA new label (Risk for Imbalanced Blood Pressure), new definition, and 20 etiological factors (11 risk factors, five associated conditions, and four at-risk populations) of the ND Risk for Unstable Blood Pressure in incarcerated women were considered valid.Implications for nursing practiceNANDA-I accepted the proposal for this nursing diagnosis; hence this study contributed to updating the classification based on scientific evidence. This evidence will favor diagnostic reasoning and recognition of the diagnosis during clinical assessment, and support studies assessing the clinical validity of these elements in incarcerated women. ObjetivoResultadosImplicacoes para a pratica de enfermagemAnalisar evidencias de validade de conteudo do diagnostico de enfermagem (DE) Risco de Pressao Arterial Instavel em mulheres encarceradas.MetodoEstudo metodologico de validade de conteudo de um DE, realizado no Brasil, entre junho e setembro de 2022, tendo 49 enfermeiros como experts. Foram avaliados o titulo, a definicao e a relevancia dos 19 fatores de risco do DE Risco de Pressao Arterial Instavel. Com base no modelo de diversidade preditiva, foram calculados o indice de Validade de Conteudo (IVC) e respectivos intervalos de confianca de 95% para cada fator de risco. IVC >= 0,8 foi considerado evidencia adequada de validade de conteudo.A relevancia de 19 fatores etiologicos mostrou IVC >= 0,8. De acordo com a recomendacao do painel de experts, um dos fatores etiologicos foi dividido em dois e dois rotulos de fatores etiologicos foram alterados. O titulo e a definicao do diagnostico foram reformulados.ConclusaoForam considerados validos um novo titulo (Risco de pressao arterial desequilibrada), nova definicao e 20 fatores etiologicos (11 fatores de risco, cinco condicoes associadas e quatro populacoes de risco) do DE Risco de Pressao Arterial Instavel em mulheres encarceradas.A NANDA-I aceitou a proposta deste diagnostico de enfermagem; portanto, este estudo contribuiu para a atualizacao da classificacao baseada em evidencias cientificas. Essas evidencias favorecerao o raciocinio diagnostico e o reconhecimento do diagnostico durante a avaliacao clinica, alem de subsidiar estudos que avaliem a validade clinica desses elementos em mulheres encarceradas.
