<div>Objetivo: Validar un instrumento que eval&uacute;e el Automanejo del Dolor en el Adulto Mayor con Osteoartritis. M&eacute;todo: Se realiz&oacute; la validaci&oacute;n en 100 Adultos Mayores con Osteoartritis, pacientes del Centro Estatal del Adulto Mayor de la ciudad de Saltillo; Coahuila de Zaragoza, M&eacute;xico. Se emple&oacute; la validaci&oacute;n de constructo y contenido mediante el consenso de juicio de expertos, adaptaci&oacute;n cultural, Alpha de Cronbach y An&aacute;lisis Factorial. Resultados: Los resultados del m&eacute;todo de m&aacute;xima verosimilitud mostr&oacute; una prueba de bondad de ajuste de KMO (0,769) y prueba de Bartlett adecuada con 3 factores; identific&aacute;ndose las dimensiones de signos y s&iacute;ntomas, adherencia al tratamiento y el conocimiento de las caracter&iacute;sticas de dolor cr&oacute;nico en la osteoartritis; con una varianza que explica el 62%. Para demostrar la confiabilidad del constructo, se realiz&oacute; la medici&oacute;n del test mediante la relaci&oacute;n entre cada &iacute;tem, obteni&eacute;ndose un Alpha de Cronbach de .812. El coeficiente de confiabilidad del constructo relacionada con la estabilidad en el tiempo entre el&nbsp;test y el retest est&aacute; expresada con una correlaci&oacute;n &ldquo;r&rdquo; de Pearson de 1 a .794 respectivamente, lo cual indica que tiene una correlaci&oacute;n significativa al nivel 0.01 positiva bilateral dependiente entre las</div><div>variables. Conclusiones: El instrumento es una herramienta v&aacute;lida y confiable en idioma espa&ntilde;ol para ser empleada no s&oacute;lo por Enfermer&iacute;a sino por todo el personal del &aacute;rea de la Salud para realizar tamizaje del Automanejo del Dolor en Adulto Mayor con Osteoartritis.
