Discusses the field of instructional systems technology (IST) and the definition of its subject matter domain; describes cognitive mapping and semantic relatedness; and reports results of a study that generated a cognitive map to define the structure of research and theory in IST. (three references) (LRW)

The consequences of using item response theory (IRT) item bias detecting procedures with multidimensional IRT item data are examined. Limitations in procedures for detecting item bias are discussed. (SLD)

Discusses the development and psychometric evaluation of the Social Support Inventory for Stroke Survivors, a multidimensional instrument for measuring social support and its influence on the rehabilitation of stroke patients. Examines the test-retest reliability and internal consistency of the instrument and suggests modifications and clinical…

TSCALE, a multidimensional scaling procedure based on the contrast model of A. Tversky for asymmetric three-way, two-mode proximity data, is presented. TSCALE conceptualizes a latent dimensional structure to describe the judgmental stimuli. A Monte Carlo analysis and two consumer psychology applications illustrate the procedure. (SLD)

Sufficient conditions are derived for the consistency and asymptotic normality of the least squares estimator of a trilinear decomposition model for multiway data analysis. The limiting covariance matrix is computed. (Author/SLD)

Multicultural research has traditionally involved normative methodology and definitions of individual differences. To further our understanding of multicultural concerns, the authors urge researchers to broaden the repertoire of methods used in these inquiries. First, the authors highlight the differences among normative, idiographic, and…

Twenty-five HIV-negative late adolescents (13 women and 12 men) who had lost a parent to AIDS generated vignettes in which the characters were deciding whether to use a condom (condom scripts). Two clinically trained judges rated the interpersonal tone of the condom scripts on 17 semantic differential scales. Three other clinically trained raters…

This study investigates the variations in behaviour displayed by young people who sexually harm, as previous research has shown that they are not a homogeneous sample. Three conceptually distinct sets of behaviour were hypothesized, relating to various modes of interaction between the young people with harmful sexual behaviour (HSB) and their…

The purpose of this study is to evaluate the domain specificity of multidimensional motivation and engagement (adaptive cognitions, adaptive behaviors, impeding/maladaptive cognitions, maladaptive behaviors) in mathematics, English and science high school subjects, with an additional focus on three key educational correlates (educational…

Guided by the social network perspective, this study examined the structural properties of the state reading policy domain using network visualization tools: sociograms and multidimensional scaling scattergrams. The authors' graphic exploration of eight state reading policy networks produced rich insights about the density and the overall…

According to the big-fish-little-pond effect (BFLPE), attending academically selective high schools negatively affects academic self-concept. Does the BFLPE persist after graduation from high school? In two large, representative samples of German high school students (Study 1: 2,306 students, 147 schools; Study 2: 1,758 students, 94 schools), the…

This paper describes a methodology, called Profile Analysis via Multidimensional Scaling (PAMS), designed to identify major patterns of variables and to study the relationships into which those patterns enter. Patterns of variables are here called profiles. The PAMS procedure has been adapted to characteristics of the National Assessment of…

The technique of nonmetric multidimensional scaling (MDS) was applied to real item response data obtained from a multiple-choice achievement test of unknown dimensionality. The goal was to classify the 50 items into the various subtests from which they were drawn originally, the latter being unknown to the investigator. Issues addressed in the…

Twenty-eight schizophrenics (14 paranoid and 14 nonparanoid) were compared with 14 normals on their judgments of similarity among words. The judgments were analyzed using an individual-differences multidimensional scaling procedure. (Editor)

This paper described one part of an item response theory (IRT) feasibility study performed for the Aptitude Test portion of the Graduate Record Examinations (GRE). The dimensionality of the GRE verbal and analytical sections is discussed. The results of six different types of equating of the verbal section and four different types of equating of…
