Construcción de un cuestionario para la evaluación de la gratitud: el Cuestionario de Gratitud – 20 ítems (G-20)

Abstract

A new questionnaire was developed in order to have an instru-ment for the assessment of gratitude. An original pool of 50 items, con-structed and reviewed using accurate standards, was filled out by 330 Span-ish undergraduates (242 females, 72.5%; 88 males), aged 18-43, M = 23.33, SD = 4.87. An Exploratory Factor Analysis concluded with the selection of 20 items with an internal four-factors structure, resulting in a scale called Cuestionario de Gratitud�20 Items. A Confirmatory Factor Analysis using the matrix of policorics correlations showed an adequated fit of the model. The questionnaire and the four components showed an internal consisten-cy between acceptable and high. The concurrent validity was checked by means of Pearson�s correlation with the Gratitude Questionnaire�Six Items Form, and discriminant validity was checked by means of confirmatory analysis of latent factors with the Purpose-In-Life Test. The results indicated that the dimensions of the Cuestionario de Gratitud�20 Ítems may be closely related with gratitude
