| Popis | The Intelligence and Development Scales - IDS (Grob, Hagmann-von Arx, Meyer, 2009) is a complex intelligence test for children (5 to 10 years). IDS consists of 19 subtests (21 in the Czech version) and focuses on 6 functional areas - Cognition, Psycho-Motor Skills, Social-Emotional Competences, Mathematics, Language, and Achievement Motivation. This study is a part of a broader standardization study of IDS, which involved 1455 children. The goals of this study are 1) to compare the factor structure of the original and Czech version, and 2) to verify meaningfulness of dividing the verbal and nonverbal subtests into 2 factors, which is based on the tradition of testing by Wechsler tests. To achieve both objectives confirmatory factor analysis (maximum likelihood) was used. The four-factor structure (Extended Cognition, Psycho-motor Skills, Social-emotional Competence and Achievement Motivation) was confirmed. This structure, except for minor differences, corresponds with the original version. Two-factor solution (Verbal and Non-verbal Cognitive Abilities) was proved to be acceptable, but high correlation of these two latent variables (r = 0.88) has been found. Factor validity of the Czech version of the IDS was proved. Moreover, our results bear important consequences for consulting practice and interpretation of intelligence test results. High correlation between latent variables Verbal and Nonverbal cognitive abilities suggests that in the general population the verbal and nonverbal subtests of IDS measures two sides of the same disposition rather than two different abilities. |
