Validity is an integrated evaluative judgment of the degree to which empirical evidence and theoretical rationales support the adequacy and appropriateness of interpretations and actions based on test scores or other modes of assessment. The principles of validity apply not just to interpretive and action inferences derived from test scores as…

Explored the concurrent validity of two measures given to students with disabilities who underwent special education assessment. Three years after tests were administered to 44 adolescents, correlations among the total and the subscale scores of these measures were high and statistically significant, excluding the difference between a verbal…

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)

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)

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 research study explores the concurrent and predictive validity of the English language proficiency screening test used by the University of Dar es Salaam (Tanzania) and the relationship of this measure to academic performance. It is concluded that (1) evidence of the predictive validity of the test supports its use for efficiently…

Responses from 403 college students on the Career Decision-Making Difficulties Questionnaire (CDMDQ) revealed a positive correlation between the CDMDQ and the Career Decision Scale (CDS) and negative correlation of these two scales with the Career Decision-Making Self-Efficacy Scale (CDMSES). Undecided students had significantly higher CDMDQ and…

This investigation compared the Peabody Individual Achievement Test and the Woodcock Reading Mastery Test scores of 131 children in grades 1-8, in order to determine whether findings of lower Woodcock scores are equally robust for each level. Differences in validity coefficients decreased from earlier to later grades. (Author/PB)

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 67 children (ages 2 to 60 months) with motor delays, found that the Battelle Developmental Inventory (BDI) possessed moderate to high levels of concurrent validity with appropriate subtests from the Vineland Adaptive Behavior Scales and the Bayley Scales of Infant Development. (Author/JDD)

A longitudinal study was designed to develop and evaluate a screening instrument of developmental delay based on parental assessment of 18-month-old children. The reliability and validity of a parental screening instrument based on the Griffiths Mental Developmental Scale was investigated with a sample of 2,783 Swedish children out of a population…

Developing good criterion measures of professional performance is difficult. If criterion-related validity evidence for certification requirements could not be generalized beyond the specific context in which it was obtained, gathering that evidence would probably not be worth the effort. This paper examines two possible approaches to the…

An important issue in educational and employment settings is the degree to which evidence of validity obtained in one situation can be generalized to another situation without further study of validity in the new situation. Theory, procedures, and applications concerning validity generalization are addressed. Meta-analytic techniques make possible…

At Cuyahoga Community College (CCC), the College-Level Examination Program (CLEP) for Introductory Macroeconomics Test was evaluated to determine if it was an effective tool for providing credit by examination for the college's Principles of Economics course. Though students at the present time (1991) can take the CLEP to obtain up to 45 credits…
