Convergent and Discriminant Validity of the Iowa Social Competency Scale for Preschool Children

Convergent and discriminant validity of the Iowa Social Competency Scale-Preschool form (ISCS-P) was investigated by using the Campbell and Fiske validity model. The methods involved were observer, mother, father, and teacher ratings whereas the traits were the three factors of the ISCS-P (Social Activator, Reassurance, and Hypersensitivity). Subjects were 92 preschool-age children, their parents, and teachers. Data were subjected to pooled within teacher correlations and reported in the form of a multitrait-multimethod matrix. Results confirmed convergent and discriminant validity for the Social Activator factor. For the Reassurance factor, convergent and discriminant validity was demonstrated for mother, father, and teacher ratings but not for observer ratings. Neither convergent nor discriminant validity was demonstrated for the Hypersensitivity factor.
