An approach to test interpretation which involves the selected use of scale items is presented. Examples are given where such item utilization could have appreciable effects upon the conclusions reached in vocational counseling. (Author)

Critiqued and reanalyzed a recent study of the validity of five Minnesota Multiphasic Personality Inventory (MMPI) alcoholism scales. The original study concluded that these scales were invalid in terms of classifying patients in regard to alcoholic status. Reanalysis provides evidence for the validity of four of the five scales.

The first of a series of quizzes on types of derived scores concerns interpreting grade-equivalent (GE) scores. The true-false items require a response about whether the stated interpretation of the GE score is sound. An answer key explains specific scoring methods. (CM)

A simple, usefully accurate approximation of the standard error of measurement is proposed for use by classroom teachers. An empirical comparison with Lord's approximation indicated that, though not as easy to calculate as Lord's, this approximation is more practical because it is useful at any point in the score distribution.

Many models have been proposed for examining factors from several batteries of tests. A model for such an analysis is presented which allows for maintaining the distinction among batteries. A discussion of the computational procedures is given, and examples are provided. (Author/JKS)

Illustrates how microcomputers can assist the instructor in scoring and analyzing classroom tests. Describes a BASIC language program adapted to several commonly available microcomputers that can be used in scoring and analyzing test results. (JOW)

Investigated subscales of the Multiscore Depression Inventory for construct and concurrent validity. Provided support for the construct validity of six scales. Concurrent validity was demonstrated with significant relationships obtained for all subscales with respective criterion measures, with the exception of learned helplessness. Discriminant…

Mathematical and statistical relationships between factor analysis and smallest space analysis are discussed. As spatial analysis of correlation matrices, factor analysis is a special case of smallest space analysis. The two differ in six ways: Shepard diagram, dimensionality, correction for communality, similarity coefficients, regions versus…

The underestimation (righting) of frame-of-reference tilt correlates with the perception of the vertical rod as tilted in the opposite direction (the rod-and-frame effect). The rod-and-frame effect can be thought of as the solution to the problem of the rod's tilt given the perceived tilt of the frame. (Author/PN)

A new procedure for determining the optimal number of interpretable factors to extract from a correlation matrix is introduced and compared to more conventional procedures. The new method evaluates the magnitude of the very simple structure index of goodness of fit for factor solutions of increasing rank. (Author/CTM)

Raw scores for the clinical scales of MMPI can be changed to T scores by linear transformation. If the underlying distributions of raw scores are not distributed normally, one cannot assume the traditional point of significance. Suggests that clinicians consider more conservative interpretation for some scales. (Author)

In this speculative article, Robert R. Rentz predicts that state educational assessment programs will continue to be fertile ground for measurement innovations, both technological and otherwise, in the areas of test content, development, administration and the reporting of test results. (AEF)

Discusses evaluation of tests both in terms of their measurement properties and their potential social consequences. Presents a model for evaluating test validity based on empirical evidence as well as on ethical decisions. Stresses the importance of construct validity as a rational foundation for test predictiveness and relevance; and the…

Criterion-referencing is a way to enhance the interpretation of test scores by referencing them to well-defined behavior domains. Behavior domains may be ordered or unordered; several varieties of criterion-referenced tests within each of these types are discussed. (Author/RL)
