Objetivo: determinar la validez de constructo y la consistencia interna del instrumento Self-Care of Hypertension Inventory (SC-HI v.2.0), traducido al español, en adultos colombianos con hipertensión arterial.
Materiales y métodos: estudio de tipo metodológico en el que se realizó traducción, adaptación cultural y validez de contenido mediante juicio de expertos. Con una muestra de 290 personas hipertensas, se determinó la validez de constructo mediante análisis factorial exploratorio (análisis de componentes principales con rotación Varimax con normalización Kaiser) y confirmatorio (análisis de máxima verosimilitud). La consistencia interna se calculó a través del coeficiente alfa de Cronbach.
Resultados: en la escala Mantenimiento del autocuidado resultó una estructura de dos factores (varianza acumulada 61 %) con buen ajuste (χ2 = 104,570; p = 0,000; RMSEA = 0,125; SRMR = 0,156; CFI = 0,856; NNFI = 0,767). En Gestión del autocuidado se obtuvo una estructura bifactorial (varianza acumulada 71 %) igualmente con buen ajuste (χ2 = 6,598; p = 0,582; RMSEA = 0,000; SRMR = 0,072; CFI = 1,000; NNFI = 1,032). En Confianza resultó una estructura bifactorial (varianza acumulada 82%) también con buen ajuste (χ2 = 94,991; p = 0,000; RMSEA = 0,194; SRMR = 0,106; CFI = 0,934; NNFI = 0,876). El alfa de Cronbach para mantenimiento (0,64), gestión (0,70) y confianza (0,86) fue aceptable.
Conclusiones: el SC-HI v.2.0 versión español colombiano posee propiedades psicométricas adecuadas, por lo que su uso es recomendado en la investigación para medir el autocuidado en poblaciones con características similares.
Objective: To determine the construct validity and internal consistency of the instrument Self- Care of Hypertension Inventory (SC-HI v.2.0) translated into Spanish in Colombian adults with arterial hypertension.
Materials and methods: Methodological study in which translation, cultural adaptation and content validity were carried out through expert judgment. With a sample of 290 hypertensive individuals, construct validity was determined by exploratory (principal component analysis with Varimax rotation with Kaiser normalization) and confirmatory factor analysis (maximum likelihood analysis). Internal consistency was calculated through Cronbach’s alpha coefficient.
Results: The self-care maintenance scale resulted in a two-factor structure (accumulated variance 61%) with good fit (χ2 = 104.570; p = 0.000; RMSEA = 0.125; SRMR = 0.156; CFI = 0.856; NNFI = 0.767). Self-care management reported a bifactorial structure (accumulated variance 71%) with good fit (χ2 = 6.598; p = 0.582; RMSEA = 0.000; SRMR = 0.072; CFI = 1.000; NNFI = 1.032). Finally, confidence scale also resulted in a bifactorial structure (accumulated variance 82%) with good fit (χ2 = 94.991, p = 0.000; RMSEA = 0.194; SRMR = 0.106; CFI = 0.934; NNFI = 0.876). Cronbach’s alpha for maintenance (0.64), management (0.70), and confidence (0.86) was acceptable.
Conclusions: The SC-HI v.2.0 in Spanish has adequate psychometric properties. Therefore, its use is recommended in research studies aimed at measuring self-care in populations with similar characteristics to that addressed in this study.

Com uma amostra de 290 hipertensos, a validade de construto foi determinada mediante análise fatorial exploratória (análise de componentes principais com rotação Varimax com normalização Kaiser) e confirmatória (análise de máxima verossimilhança). A consistência interna foi calculada por meio do coeficiente alfa de Cronbach.
Resultados: a escala de manutenção do autocuidado resultou em uma estrutura de dois fatores (variância acumulada 61 %), com bom ajuste (χ2 = 104,570; p = 0,000; RMSEA = 0,125; SRMR = 0,156; CFI = 0,856; NNFI = 0,767). Na gestão do autocuidado, foi obtida uma estrutura bifatorial (variância acumulada 71 %), com bom ajuste (χ2 = 6,598; p = 0,582; RMSEA = 0,000; SRMR = 0,072; CFI = 1,000; NNFI = 1,032). Na confiança, resultou uma estrutura bifatorial (variância acumulada 82 %), com bom ajuste (χ2 = 94,991; p = 0,000; RMSEA = 0,194; SRMR = 0,106; CFI = 0,934; NNFI = 0,876). O alfa de Cronbach para manutenção (0,64), gerenciamento (0,70) e confiança (0,86) foi aceitável.
Conclusões: o SC-HI v.2.0 versão em espanhol variante colombiana apresenta propriedades psicométricas adequadas, portanto seu uso é recomendado em pesquisas para mensurar o autocuidado em populações com características semelhantes às do presente estudo.
