The degree to which variations in the face validity of psychological tests affected students' willingness to accept personality interpretations was studied. Acceptance of personality interpretations was compared for four types of tests which varied in face validity. The relationship between judged accuracy and rated likability of the…

An overview of generalizability theory and a FORTRAN computer program for studying the generalizability of scores in a three facet, four factor design are presented. An illustrative example is presented. (Author/JKS)

An efficient algorithm for maximizing split-half reliability coefficients is described. Coefficients derived by the algorithm were found to be generally larger than odd-even split-half coefficients or other internal consistency measures and nearly as large as the largest split half coefficients. MSPLIT, Odd-Even, and Kuder-Richardson-20…

Chronic pain outpatients (N=600) randomly split and their symptom Checklist-90 responses were analyzed via a three-step factor analysis. A 10-factor model was judged most meaningful and statistically appropriate in the first-order analysis. The second-order analyses produced three factors. All factors replicated across the data halves, providing…

Test statistics based on the assumption that test scores are interval rather than ordinal quality data are questioned. New statistical techniques which do not rely on this assumption are presented. (JKS)

The paper explores data interpretation in observational recording by examining and illustrating techniques for visually inspecting graphically displayed data. These procedures may assist the educator in determining the impact of intervention procedures on learner performance. (Author/CL)

Derived empirical descriptions of 113 adults independent of the Minnesota Multiphasic Personality Inventory for profiles classified according to most frequently occurring two-point codes. Compared subjects of each code type group to remaining subjects on 255 behavior variables, resulting in development of interpretive narratives for 3-5/5-3,…

This paper demonstrates that, although aggregated standard scores can correlate substantially with aggregated raw scores, their correlations with an external criterion can differ markedly. This will occur when the variances of the components differ, and these differences are related to the correlations of the components with the criterion. (Author)

Profile analysis refers to interpreting or analyzing the pattern of tests, subtests, or scores. The analysis may be across groups or across scores for one individual. This approach to analyzing data is being used by clinicians to help in the translation of the results of popular assessment instruments. This paper examines several examples of the…

Investigated canonical relationship of the Wechsler Intelligence Scale for Children-Revised Verbal and Performance scales. Found relationship to be similar to that of the Wechsler Adult Intelligence Scale-Revised, but less strong. Found two scales shared 46 percent of their variance. Results support independent interpretation of the Verbal and…

Presents age-referenced tables for Wechsler Preschool and Primary Scale of Intelligence-Revised that provide differences required at .05 and .01 levels of significance between any Verbal scale subtests and average of Verbal scale subtests, any Performance scale subtests and average of Performance scale subtests, and any subtest with average of all…

Post hoc and planned comparison procedures for interpreting chi-square contingency table test results are presented, and a planned comparison procedure that simplifies the process of creating a contingency table by creating single-degree-of-freedom contrasts through a regression-based approach is proposed.

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,…

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…
