Resumen
La seriedad de todo instrumento de medición científica radica en su validez y
confiabilidad. Con el objetivo de realizar un estudio técnico para determinar validez y
confiabilidad dedos cuestionarios para medir efectos de la jubilación, se realiun
estudio descriptivo, no experimental, de campo, transeccional, con 40 venezolanos
jubilados y 40 familiares de estos. El primer cuestionario “EJUJ”, constituido por 59
ítems, pretende medir efectos en el jubilado, el otro cuestionario “EJUFA”, con 39
ítems, mide efectos en la familia del jubilado. El procedimiento para determinar validez
de contenido fue con panel de expertos; para la confiabilidad se usó el coeficiente alfa
de Cronbach y coeficiente partición por mitades. En el cuestionario EJUJ se encontró
respecto a confiabilidad 0.895 de coeficiente Alfa Cronbach, 0.769 correlación entre
mitades y 0.87 coeficiente de división por mitades, revelando alta confiabilidad. En
validez de contenido, los expertos coincidieron en modificar redacción en catorce
ítems, incluir uno nuevo y dividir otros 6 en dos preguntas casa uno. La confiabilidad
del cuestionario EJUFA arrojó 0.94 de coeficiente Alfa Cronbach, 0.824 correlación
entre mitades y 0.903 coeficiente de división por mitades, indicando alta confiabilidad.
En cuanto a validez de contenido, los expertos sugirieron modificar redacción de doce
ítems y dividir en dos preguntas diferentes otros 5. Se obtuvo el cuestionario EJUJ con
59 ítems agrupados en nueve sub-dimensiones y EJUFA con 39 ítems en ocho sub-
dimensiones que miden efectos de la jubilación, con valores psicométricos que los
acreditan como válidos y confiables para la población venezolana.
Palabras clave: Propiedades psicométricas, cuestionarios, jubilación, efectos.
