Diseño y Validación de un Instrumento para Analizar el Dimorfismo Sexual en las Preferencias Lúdicas de Niños Preescolares.

The aim of the study was to design and determine the psychometric properties of an instrument to analyze sexual dimorphism in play preferences in a preschool population. A total of 231 children between 3 and 6 years of age participated. An exploratory factor analysis showed a scale with three factors. There are significant differences in the choice of male and female games. In male games, the results at 4 and 6 years of age indicate that boys show a greater predilection for these games than girls (p=.002, Cohen's d=1.031 and p<.001, Cohen's d=1.435). At ages 5 and 6, girls show a greater predilection for female games (p=.014, Cohen's d=.665 and p=.049, Cohen's d=.574) than boys. In conclusion, the psychometric analyses provide evidence of validity and reliability of the questionnaire, which can be used to analyze play behavior from 3 to 6 years of age. [ABSTRACT FROM AUTHOR]
