A test battery that corresponded to the Gesell Developmental Assessment (GDA) was given to 400 4-6 year olds. A truncated version of the GDA had moderate reliability and predictive power. Experienced judges sometimes differed in their assessments of a child's developmental level and recommendations for grade placement. (GLR)

The efficacy of screening two-year-old children for language delay using a parent report questionnaire was investigated in three related studies. Parents' reports of children's expressive vocabulary size was highly correlated with clinical language measures at age two, but somewhat less accurate at predicting developmental status a year later.

Objective: Interview data collected from 275 clients with severe mental illnesses are used to test the construct and criterion validity of the Posttraumatic Stress Disorder Symptom Scale (PSS). Method: First, exploratory and confirmatory factor analyses are used to test whether the scale reflects the posttraumatic stress disorder (PTSD) symptom…

Discriminant function analysis assessed the predictive relevance of nine characteristics measured in sixth grade for differentiating among social identities claimed 4 years later by 616 participants in the Michigan Study of Life Transitions. For females, the first discriminant function, associated with academic motivation, self-esteem, and…

This study explores the predictive validity of GMAT[R] scores for predicting performance in graduate management programs outside the United States. Results suggest that the validity estimates based on the combination of GMAT[R] scores were about a third of a standard deviation higher for non-U.S. programs compared with existing data on U.S.…

This study empirically evaluates the technology acceptance model drawn from Information Systems (IS) literature to investigate how user beliefs and attitudes influence learning-object use among higher education learners by evaluating the relationships between perceived usefulness, perceived ease of use, attitude, behavioural intentions and actual…

Pedhazur and Tetenbaum speculated that factor structures from self-ratings of the Bem Sex-Role Inventory (BSRI) personality traits would be different from factor structures from desirability ratings of the same traits. To explore this hypothesis, both desirability ratings of BSRI traits (both "for a man" and "for a woman") and…

Problem behavior is a major barrier to successful community integration for people with developmental disabilities. Recently, there has been increased interest in identifying contextual factors involving setting events and discriminative stimuli that impact the display of problem behavior. The authors previously developed the "Contextual…

Applications for places in UK Higher Education are usually made before the results of A-level examinations are known, so references from schools and colleges normally refer to expected (or predicted) grades. Inaccuracies in these predictions may be systematically related to key characteristics of the applicant and could lead to…

To be able to offer children with developmental disorders adequate help, professionals working in special needs education must use a screening device to assess the specific psychiatric difficulties of the children. In this paper the psychometric properties of an easy-to-use parental rating scale to screen symptoms of major psychiatric disorders…

Objective: To use experience sampling method (ESM) to examine the impact of inattentive and hyperactive-impulsive ADHD symptoms on emotional well-being, activities and distress, cognitive impairment, and social functioning assessed in the daily lives of young adults. The impact of subjective appraisals on their experiences is also examined.…

Although the Miller Analogies Test (MAT) is used extensively as an admissions test for graduate programs, relatively little research has examined the validity of the MAT for predicting subsequent graduate student achievement and no published studies have examined differential prediction of student performance from MAT scores. There were two…

Since 1964, colleges have been sending data to the College Board Validity Study Service to allow determination of the degree to which measures used in admissions predict college performance. Beginning in the early 1970s and continuing into the mid 1970s, the observed average correlations of Scholastic Aptitude Test (SAT) scores with freshman…

This study, based on the Rasch model, used R. M. Smith's (1986) classification of measurement disturbances to assess the Rasch model approach to error control and statistical prediction. Partitioning the error component into a person component, an item-person interaction component, and a random unexplained error component has the net effect of…

This study investigated whether or not the validity of the Scholastic Aptitude Test (SAT) is both higher and less variable across colleges than it appears to be. Data from 99 validity studies conducted by the Validity Study Service of the College Board were used. In addition to test validities based on first-year college averages, which were…
