Antecedentes. La escala breve de Francis para actitud ante el cristianismo (Francis-5) muestra alta consistencia interna y confiabilidad de tipo prueba-reprueba en adolescentes colombianos. Sin embargo, las investigaciones sólo están disponibles en inglés y no se conoce la validez nomológica de escala en esta población.
Objetivo. Corroborar la validez y confiabilidad de la escala Francis-5 en adolescentes estudiantes de Cartagena, Colombia.
Material y métodos. Participaron 1.730 estudiantes de sexto a undécimo grado, con una media para la edad de 14,7 años (DE=1,2), y 52,7% mujeres. Se estimó la validez de constructo (análisis de factores) y la validez nomológica (comparación de las puntuaciones entre mujeres y varones). Para conocer la confiabilidad se calcularon los coeficientes alfa de Cronbach y omega de McDonald.
Resultados. La escala Francis-5 mostró una estructura unidimensional, con un valor propio de 3,681 que dio cuenta del 73,6% de la varianza. Las mujeres puntuaron significativamente mayor que los varones, 18,5 (DE=2,7) vs. 17,9 (DE=3,3) (t = 4,3; p<0,001). El coeficiente alfa fue 0,909 y; el omega, 0,910.
Conclusiones. La Francis-5 es una escala válida y confiable en estudiantes adolescentes de Cartagena, Colombia. Se necesita conocer el desempeño de esta escala en otras regiones colombianas.
Background. The short version of Francis Scale attitude toward Christianity (Francis-5) presents high internal consistency and test-retest reliability among Colombian adolescents. However, the papers are only available in English, and nomological validity is not known in this population.
Objective. To corroborate the validity and reliability of the Francis-5 scale among adolescent students at Cartagena, Colombia.
Materials and method. A total of 1,730 sixth to eleventh grade students, mean age of 14,7 years old (SD=1.2), and 52.7% were girls. Construct validity (factor analysis) and nomological validity (score comparison between boys and girls) were explored. Cronbach alpha and McDonald omega were computed as measures of reliability.
Results. Francis-5 Scale showed one dimensional structure, with Eigen value of 3.681 that accounted for 73.6% of the total variance. Girls scored significantly higher than boys, 18.5 (SD=2.7) versus 17.9 (SD=3.3) (t=4,3; p<0.001). Coefficient alpha was 0.909; and coefficient omega, 0.910.
Conclusions. Francis-5 is a valid and reliable scale among adolescent students at Cartagena, Colombia. It is needed to investigate its psychometric performance in others Colombian population.
