Fifty-seven primary-level students completed the Detroit Tests of Learning Aptitude-Primary: Second Edition (DTLA-P:2) and the Woodcock-Johnson Psycho-Educational Battery, Part I and II. A strong relationship between the two provides evidence for the criterion-related and construct validity of the DTLA-P:2 test scores. (Author/JDD)

Rasch calibration procedures were applied to item-response data for the 1,262 infants and toddlers comprising the standardization sample for the Mental Scale of the Bayley Scales of Infant Development. Analyses tend to confirm the psychometric integrity of the instrument. (Author)

This study examined the construct validity of the KeyMath-Revised by testing the factorial model proposed by the test author. Results failed to confirm the proposed factorial model and suggested that the KeyMath-Revised assesses two domains that are difficult to interpret, rather than the three proposed by the test author.

Reliability and construct validity of over 1,000 mothers' responses to the Disruptive Behavior Rating Scale-Parent Version were studied. Results indicated excellent internal consistency and test-retest reliability on three subscales (Oppositional, Distractible, and Impulsive-Hyperactive) but only marginal reliability on the Antisocial Conduct…

Construct validity of the Wechsler Intelligence Scale for Children-Revised using 189 Black, 184 Hispanic, and 187 White 6- to 11-year-olds was investigated. A two-factor solution yielded similar loadings corresponding to verbal comprehension and perceptual organization for all three groups. Three-factor solutions yielded similar loadings for…

The construct validity of the Preschool and Kindergarten Behavior Scales (PKBS) was evaluated with 94 kindergarten students. Results supported both the convergent and discriminant validity of the Social Skills and Problem Behavior scales of the PKBS. Results also support use of the PKBS for identifying young children who are behaviorally at risk.…
