A volume consisting of MMPI profiles based upon groups is reviewed. (DB)

The notion of scale freeness does not seem to have been well understood in the factor analytic literature. Misconceptions concerning scale-freeness are clarified, and a theorem that ensures scale freeness in the orthogonal factor model is given in this paper. (Author/JKS)

The Wechsler Adult Intelligence Scale-3rd Edition (WAIS-III) was released in 1997. Short forms developed for previous versions have not yet been investigated for the WAIS-III in special populations. A 4-subtest short form by A. B. Silverstein emerged as the most promising short form in an elderly sample. (Contains 49 references, 4 tables, and 2…

Notes that studies in psychology often have low power because of inadequate sample size and that prevalent psychometric distributions are sometimes radically nonnormal. Demonstrates robustness of independent samples t-test with respect to Type I error. Shows that researchers may use power tables based on population normality without modification…

Proposes a method for performing survival analysis with latent variables with dual aims of scoring subjects with respect to a psychological variable of interest and distinguishing the varying extents to which items are capable of measuring the construct. Illustrates this discrete proportional hazards model. (SLD)

Introduces a section of class handouts from Professor Benjamin D. Wright at the University of Chicago. Handouts summarize concepts in psychometrics and measurement techniques. (SLD)

Outlines essential points to learn in psychometrics, listing "basics" and essential concepts in measurement and statistics, and showing the importance of the Rasch model. (SLD)

Latent variable models for an infinite sequence (or universe) of manifest variables that may be discrete, continuous, or a combination of both, are considered. A main theorem is presented that characterizes when it is possible to construct latent variable models that satisfy unidimensionality, monotonicity, conditional independence, and tail…

The main purpose of this article and this special section is to encourage greater attention to evidence-based assessment (EBA) in the development of a scientifically supported clinical child and adolescent psychology. This increased attention is especially important in light of (a) the omission of assessment considerations in recent efforts to…

Quantitative psychology is concerned with the development and application of mathematical models in the behavioral sciences. Over time, models have become more complex, a consequence of the increasing complexity of research designs and experimental data, which is also a consequence of the utility of mathematical models in the science. As models…

We are very grateful for the thoughtful, scholarly, and insightful comments of the reactants and appreciate the kind words about our Major Contribution. One of the goals of the Major Contribution was to review the existing literature on problem-solving appraisal as measured by the Problem Solving Inventory (PSI) (Heppner, 1988) and, subsequently,…

Attention is brought to the existence of incongruity in the definition of reliability in the literature, and some unnecessary controversies and confusions which result. A conventionalization of the meaning of reliability at a conceptual, model-free level is proposed. Through the exploration of two paradoxes, this article attempts to address some…

There are a large number of studies demonstrating that visuospatial working memory (VSWM) involves different subcomponents, but there is no agreement on the identity of these dimensions. The present study attempts to combine different theoretical accounts by measuring VSWM. A battery composed of 13 tests was used to assess working memory and, in…

The purposes of this study are: (1) to investigate whether cloze forms with text-driven deletion method, proposed by Farhady and Keramati (1996), will produce better psychometric properties than standard cloze form; (2) to compare the psychometric properties of cloze test and C-test, both of which belong to the family of language reduced…

Investigating the emotional impact of music listening has a long history. Indeed, reactions to subtle as well as obvious changes in music, whether inadvertent or deliberate, occupy a good deal of interest for the music researcher as well as the music educator. Regardless of the extremely subtle acoustic changes that are perceptible within almost…
