Factor structure of the McCarthy Scales in 7-year-old Spanish children
Juana Gómez‐Benito, María Forns-Santacana · Psychology in the Schools · 1996
This study was designed to examine the construct validity of the McCarthy Scales for 7-year-old Spanish children, using factorial analysis. Based on a sample of 128 children with a mean General Cognitive Index of 104 (SD = 15.37), five factors were generated by principal component analysis, and one factor by principal factor analysis. An analysis of congruence between the factorial matrices of 7- and 4-year old children was performed. The degree of similarity of factors between sample was determined by means of a technique of factorial invariance using Tucker's coefficient of congruence. © 1996 John Wiley & Sons, Inc.
