To analyze differential diagnostic efficiency of the Revised Illinois Test of Psycholinguistic Abilities (a measure designed to assess strengths and weaknesses of learning disabled children), the Kelley procedure for estimating the proportion of differences in excess of chance was applied to the standardization data. (SBH)

The book is intended to assist persons using the Illinois Test of Psycholinguistic Abilities (ITPA) to interpret test results and organize remedial programs for students with psycholinguistic learning disabilities. The concept of learning disabilities is discussed and the development and meaning of the 12 ITPA subtests are explained. Selected…

Two hypotheses were examined in this research project: (1) children with high level perceptual skills in the initial assessment will retain their advantage but will grow less in skills than children with low level skills development at the outset; and (2) after a period of skills development, children with high level skills development will show…

Studied the degree to which skewed score distributions can affect the interpretation of Illinois Test of Psycholinguistic Abilities (ITPA) Results suggest indices of score variability such as average deviation and standard scores must be interpreted with extreme caution when skewness is a significant factor.

This study attempted to develop a diagnostic-prescriptive curriculum program to improve the school readiness of disadvantaged preschoolers. The language development patterns of 32 3-, 4-, and 5-year-olds were diagnosed by use of the Illinois Test of Psycholinguistic Abilities (ITPA). Teachers were trained to use this information to provide an…

The article explains standardization procedures used for the Illinois Test of Psycholinguistic Abilities (ITPA) and some of its technical characteristics as well as how such information should influence decisions for determining a child's need for special education. (Author/PHR)

AN INVESTIGATION OF THE VALIDITY OF INTELLIGENCE AND OTHER TESTS USED IN THE DIAGNOSIS OF RETARDED CHILDREN WAS PERFORMED. EXPERIMENTAL SAMPLES CONSISTED OF 101 CHILDREN SELECTED FROM SPECIAL CLASSES FOR EDUCABLE MENTALLY RETARDED (EMR) WHOSE AGES RANGED FROM 6.9 TO 10 YEARS AND WHOSE IQ SCORES RANGED FROM 50 TO 80. THE TESTS EVALUATED WERE (1)…

This study was designed to factor analyze the correlation matrices of a number of studies utilizing the Illinois Test of Psycholinguistic Abilities (ITPA). All of the correlation matrices were analyzed on the same program using the same criteria. By this approach, it was possible to examine trends between studies. More factors tended to appear as…

An estimated ITPA Psychological Quotient (PQ) was compared to the WISC-R Verbal, Performance, and Full Scale IQs of developmentally disabled children, ages 6 to 13. The PQ related strongly to Verbal and Full Scale IQs. Implications for diagnosis and screening are discussed. (Author/SJL)

The article describes the circumstances leading to the development of the Illinois Test of Psycholinguistic Abilities and discusses the malpractices in administration, scoring, and interpretation of the test. (Author)

Investigated the construct validity of the 10 primary Illinois Test of Psycholinguistic abilities subtests in a clinical population of learning disabled children (N=91). Results via factor analysis and correlational analyses generally supported the independence of the channel dimension, i.e., visual versus auditory. The dimension of levels…
