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 Slosson Intelligence Test (SIT) and the Stanford-Binet, Fourth Edition (SBIV) were administered to 95 elementary students referred because of either learning problems or potential giftedness. SIT scores predicted SBIV verbal scores more accurately than composite scores. Overall the SIT predicted SBIV scores better for students with learning…

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…

The response to a previous article by Mardell-Czednowski and Lessen notes the lack of common criteria for evaluating technical adequacy of assessment instruments used with handicapped children and stresses the need to evaluate instruments with the specific populations to which they are administered. (DB)

Special education tests evaluated by M. Thurlow and J. Ysseldyke with regard to technical adequacy were reevaluated using the same criteria. There was disagreement of 11 of the 30 tests used in both evaluations, demonstrating that current test standards are vague enough that experts disagree. (Author/CL)

Thirty-two preschool children were administered the Cognitive Levels Test (CLT) to evaluate its temporal stability and concurrent validity. Results indicated good temporal stability for the CLT-Cognitive Index and high correlations between the CLT-Cognitive Index and the Stanford-Binet: Fourth Edition. (Author/JDD)

This study evaluated the technical qualities of a naturalistic test of reading decoding skills, the"Diagnostic Names Task." Evaluation of the measure with 25 elementary grade disabled readers examined subtest reliability, sensitivity to change resulting from instruction, meaningful clustering of subskills, and criterion-related validity.…

Content validity is an overriding problem in all measures evaluating written expression because there is no complete model of written language. Direct atomistic measures have greater instructional utility in diagnostic assessment, grouping, monitoring and decision making, reporting student progress, and giving feedback to students than do indirect…

This assessment of the reliability and validity of skills analysis programs within curriculum-based measurement (CBM), with various groups of handicapped and nonhandicapped youngsters, indicated that the skills analysis programs in spelling and math provided consistent information that related well to the primary graphed CBM scores. (Author/JDD)

Results established the indicator's technical adequacy and further defined the self-concept/level of aspirations relationship as supporting evidence of construct validity. (Author)

The use of multidomain instruments for screening or diagnostic purposes with handicapped infants and preschoolers is reviewed. Purposes of assessment and criteria for instrument utility are presented. Five multidomain screening tools and three multidomain diagnostic instruments are reviewed with respect to their validity, reliability, and utility.…

Studies of the reliability, normative data, construct validity, and concurrent validity of the Social Perception Behavior Rating Scale used with mildly learning-disabled, behavior-disordered, and nondisabled children indicated adequate reliability, marked differences in scores of handicapped and nonhandicapped children, and a logical pattern of…

A study involving 120 school-aged children that investigated the concurrent validity of measures of written language found that the Wechsler Individual Achievement Test Written Expression subtest correlates moderately with the Written Expression subtest of the Peabody Individual Achievement Test-Revised and the Spontaneous Writing Quotient of the…

Information on the Vineland Adaptive Behavior Scales, a major revision of the Vineland Social Maturity Scale, covers authors, publisher, prices, copyright dates and revisions, groups for whom the instrument is intended, forms, purpose and recommended use, dimensions measured, administration, data summation, score interpretation, test…

In order to locate optimal cutoff scores for detecting developmental delays, the Brigance Screens were administered to 408 children (ages 21-48 months) along with a criterion battery measuring achievement and intelligence. The Receiver Operating Characteristic analyses were then used to locate optical cutoff scores for each form of the Brigance.…
