Homogeneity Reliability of the it Scale for Children

Abstract

Although the It Scale for Children (IT scale) is probably the most commonly used measure of sex-role preference in children, its test homogeneity has not been previously reported. The IT scale was administered individually to 38 boys and 40 girls in grades N through 2 of a university school by either a male or a female experimenter. The homogeneity coefficient for girls was larger than that for boys ( p < .01). Neither the Sex of E nor the interaction, Sex of S × Sex of E, was significant. Although the coefficients for girls and boys were large enough for basic research, only the coefficient for girls was large enough for diagnostic work with present sample sizes. Further investigation of the test homogeneity of the IT scale was suggested.
