Discusses Bauman's (1991) evaluation of stability of Wechsler Intelligence Scale for Children (Revised) IQs in children with learning difficulties. Argues that some procedures produced magnified estimates of instability. Presents reanalysis of data that suggests that, although stability coefficients were high, approximately 25 percent of sample…

Presents psychometric investigation of the eight-factor clinical model of the Suicide Opinion Questionnaire (SOQ) as representing the most appropriate interpretive model for the SOQ. Notes that factor-analytic and internal consistency reliability results failed to support hypothesized eight-factor model. Discusses alternative factor scheme and…

Examined interpretations of 100 career counselee's responses to Self-Directed Search (SDS). Found that agreement between scales identified as relevant was as high as agreement among counselors, insignificant correlations between counselors' judgments of counselee's degree of interest crystallization and Holland's (1985) measure of consistency, and…

Provides new confidence intervals for Wechsler Intelligence Scale for Children-Revised (WISC-R) to improve accuracy over existing tables. Includes alternative confidence interval tables for WISC-R quotients at extreme levels where current tables are least accurate. New tables center confidence intervals on estimated true intelligence quotient and…

Analyzes the three major inferences involved in interpretation of performance assessments: (1) scoring of the observed performances; (2) generalization to a domain of assessment performances like those included in the assessment; and (3) extrapolation to the large performance domain of interest. Suggests ways to improve the validity of performance…

Assessed the interrater reliability of the revised Advanced Psychodiagnostic Interpretation (API) (A. Raphael and C. Golden, 1998) scoring system for the Bender Gestalt Test (L. Bender, 1938). Agreement across nine raters exceeded 90% for each of three clinical protocols, and kappa statistics indicated good interrater reliability. (SLD)

Describes mapping variables, the principal technique for planning and constructing a test or rating instrument. A variable map is also useful for interpreting results. Provides several maps to show the importance and value of mapping a variable by person and item data. (Author/SLD)

Two styles of test interpretation (TI), delivered and interactive, were manipulated in a 1-session counseling interview. The favorability of the interpretations (i.e., positive only and mixed) was also manipulated. After completing a well-known personality test, 46 participants completed the TI session. Participants' thoughts and perceptions of…

According to J. B. Carroll's (1993) 3-stratum theory, performance on any subtest reflects a mixture of both 2nd-order and 1st-order factors. To disentangle these influences, variance explained by the general factor should be extracted first. The 1st-order factors are then residualized, leaving them orthogonal to the general factor and each other.…

We developed equivalent, alternate forms of easyCBM[R] in reading (n=20 forms) and mathematics (n=13 forms) with different skills reflective of the National Reading Panel (NRP) and the National Council of Teachers of Mathematics (NCTM), respectively. We then took three forms to use as screening measures in the fall, winter, and spring so educators…

In this article, the author reviews the Battelle Developmental Inventory, 2nd edition (BDI-2), a criterion-referenced, individually administered, standardized assessment used to measure the developmental skills in children aged birth through 7 years, 11 months. The BDI-2 is composed of 450 items grouped into five domains (Adaptive,…

Issues regarding confidence and tolerance intervals are discussed within the context of educational measurement. Conceptual distinctions are drawn between these two types of intervals; and examples, under various error and true score models, are used to compare such intervals. It is shown that there tend to be only small differences in tolerance…

The factor analytic studies that have been done with the Millon Clinical Multiaxial Inventory (MCMI), a 175-item paper-and-pencil test designed to evaluate symptomology in psychiatric patients, have been problematic in that the test's high inter-scale correlation could lead to an artificially robust factor structure. The present investigation…

In efforts to clarify ambiguity in the scoring directions for part of the WISC, 100 children were given the test which was scored by two sets of criteria. Four sets of data were analyzed, with significant discrepancies apparent only between Verbal-Performance correlations secured by Wechsler in his standardization of the WISC and those secured in…

A review of five interrelated studies showed that certain preselected SVIB occupational scales were indicative of life styles related to accident incurrence. The hypothetical formulation underlying these studies was that vocational interest scores reflect enduring personal characteristics. (Author)
