This article defines test bias and reviews research methods most aptly applied postpublication to educational and psychological tests. Best methods for estimating bias in criterion-related or predictive validity and determining bias in construct validity across groups are explained. (Author/JDD)

The usefulness and validity of the 3 versions (Infant-Toddler, Early Childhood, and Middle Childhood) of the HOME Inventory were studied with 261 children with cognitive, hearing, vision, or orthopedic handicaps. The Inventory in its original form and a modified form was subjected to analysis of reliability, construct validity, and criterion…

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)

The Cognitive Levels Test (CLT) and the Peabody Picture Vocabulary Test-Revised (PPVT-R) were administered to 30 freshman college students at a small state college in the mid-Atlantic region. Significant correlations indicate that the PPVT-R measures a component of the CLT. Mean PPVT-R scores were significantly higher than CLT means. (Author/PB)

This study evaluated the Clarke modification of the Questionnaire on Resources and Stress with parents (n=367) of autistic, mentally retarded, learning-disabled, and asymptomatic children. Good internal consistency, split-half reliability, and coefficient of stability were obtained as well as acceptable construct and concurrent validities.…

Home interviews conducted with 102 families of children with developmental delays assessed ecocultural family resources, values, goals, and proactive adaptive efforts. Factor analyses on the ecocultural measures revealed 12 salient factors. Some factors were unique and statistically independent of traditional home environment measures. Significant…

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)

The Turkish edition of the Test Anxiety Inventory (TAI-T) was accomplished in three stages, each stage constituting an independent study with new samples. In the first study, using bilingual Turkish high school and college students, the transliteral equivalence between the Turkish and English TAI items were achieved. The second study, using a…

This study compared global scores of 26 Australian students (ages 4 to 16) with mental retardation on the third and fourth editions of the Stanford Binet Intelligence Scale. Analysis indicated a fairly strong positive relation between the two tests, suggesting that the fourth edition may be substituted for the older instrument in longitudinal…

This study established criterion-related validity for the Reading Passages Subtest of a locally developed curriculum-based measurement (CBM) instrument, with cross-validation across reading curricula and criterion measures. Correlations of 479 primary grade students' reading scores on the Comprehensive Test of Basic Skills provided support for CBM…

Concurrent validity testing of the Slosson Intelligence Test-Revised with the Stanford-Binet Intelligence Scale (Fourth Edition), involving 191 individuals (ages 5-69 and IQs of 36 to 110), found a high correlation between the two scales. However, the Slosson unsatisfactorily matched the Stanford-Binet's assignment of individuals to IQ categories.…

The concurrent validity of three types of reading ability assessments was evaluated with 312 Australian primary-level children. Results suggest that the nature of the skills required for success in reading changes in the primary years, and that both teacher-based and test-based assessments concur more closely as children progress through the…

The concurrent validity of the Battelle Developmental Inventory was explored by correlating Battelle results with scores from the Bayley Scales in 30 infants with known or suspected disabilities. Both the pattern and strength of the obtained correlations support use of the Battelle to measure development in infants with handicaps. (Author/JDD)

This study, involving 118 adolescents and adults with deafness, found a high level of concurrent criterion validity for the National Independent Living Skills (NILS) Screening Instrument. The study concluded that the NILS is a valid tool for assessing independent living skills of persons age 16 and older with a hearing impairment and possible…

A total of 413 students in grades 1-6 were administered the Basic Academic Skills Samples, the Gates-MacGinitie Reading Tests, and the Metropolitan Achievement Test. Although the relationships among the three tests were reasonably strong, it appeared that the measures did not identify identical populations of at-risk students. (Author/JDD)
