The present study examined whether learning disabilities (LD) in reading and/or math (i.e., reading disability [RD], math disability [MD], and RD+MD) co-occur with other diagnoses. The data comprised a clinical sample (n = 430) with LD identified in childhood and a sample of matched controls (n = 2,140). Their medical diagnoses (according to the…

Our purpose was to study the frequency of behavioral-emotional problems among children identified with a learning disability (LD). The data were obtained for 579 Finnish children (8-15 years) with reading disability (RD-only), math disability (MD-only), or both (RDMD) assessed at a specialized clinic between 1985 and 2017. We analyzed percentages…

We studied the impact of diverse subtypes of learning disabilities (LD) on adult-age mental health, education, and employment by comparing the LD group (n = 430) with a matched control group without a known history of LD (n = 2,149). The clinical archived data were merged with lifelong register data on sickness allowances/disability pensions…

The study compared the performance of 18 elementary-age students with learning disabilities on the Stanford-Binet Intelligence Scale: Fourth Edition and the Kaufman Assessment Battery for Children. Correlations (corrected for restriction of range) between the two instruments were strong. (Author/DB)

A learning disability index (LDI) for the assessment of intellectual deficits on the K-ABC is described. The population parameters of this index allows for assessment of the abnormality of the LDI in the individual case, as well as for evaluation of statistical significance of any change in the LDI from test to retest.

Comparison of scores on the Kaufman Assessment Battery for Children and the Wechsler Intelligence Scale for Children-Revised of 67 students (ages 6-12) referred for possible learning disabilities found strong relationships among all the global standard scores on both instruments with different score patterns for those with severe disabilities.…

Learning Disabled children (N=198) were tested on both the WISC-R (Wechsler Intelligence Scale for Children-Revised) and K-ABC (Kaufman Assessment Battery for Children). Joint factor analysis produced three-factor and four-factor solutions. Factors corresponding to three K-ABC scales generally converged with three WISC-R factors. (Author/CL)

The study examined correlations between the Wechsler Intelligence Scale for Children-Revised (WISC-R), the Peabody Picture Vocabulary Test-Revised (PPVT-R), and the Kaufman Assessment Battery for Children (K-ABC) for 44 learning disabled primary and intermediate special class students. The Mental Processing and Achievement scales of K-ABC…

This study evaluated the external validity of a measure of IQ subtest variability, the profile variability index (PVI), with a sample of 146 children referred for psychological testing. Correlation of PVIs on each intelligence test with achievement scores and indexes of discrepancy between actual and predicted scholastic achievement found…
