Reexamines a 49-year-old study of P technique applied to a psychotherapy patient with a recurrent physical symptom. Explores dimensions of psychotherapeutic change as well as the context for the recurrent symptom. Illustrates the contributions from applying the P technique to psychotherapy research, to psychosomatic medicine, and to personality…

This article reports on two studies that used three different samples (N = 644) to construct and validate a multidimensional measure of managerial coaching skill. The four dimensions of coaching skill measured were Open Communication, Team Approach, Value People, and Accept Ambiguity. The two studies assessed the context adequacy, dimensionality,…

Administration of the Test of Spoken English (TSE) yields tapes of oral performance on items within six sections of the test. Trained scorers subsequently rate responses using four proficiency scales: pronunciation, grammar, fluency, and overall comprehensibility. This project examined the consistency of statistical relations among TSE scores with…

The effects of varying degrees of correlation between abilities and of various correlation configurations between item parameters on ability and item parameter estimation using the three parameter logistic model were examined. Ten two-trait configurations and one unidimensional test configuration for 30 item tests were simulated. Each…

The factorial structure of the Rotter Internal-External (IE) scale was examined. While there was strong evidence against the unidimensionality of the Rotter scale, the findings suggested that the first-order factors do define a single higher-order construct that may represent the generalized IE construct.

A copy of the computer program, which determines the transformation matrix used to rotate the configuration, the dilation factor, and the translation vector, is available from the first author. (CB)

Examination of a test's internal structure can be used to identify what domains or dimensions are being measured, identify relationships between the dimensions, provide evidence for hypothesized multidimensionality and test score interpretations, and identify construct-irrelevant variance. The purpose of this research is to provide a…

The present monte carlo simulation study was designed to examine the effects of multidimensionality during the administration of computerized adaptive testing (CAT). It was assumed that multidimensionality existed in the individuals to whom test items were being administered, i.e., that the correct or incorrect responses given by an individual…

The model of cognitive ability proposed by John B. Carroll is described and its implications for education traced. The Carroll model is unique in that it is based on datasets reanalyzed by standard procedures. The variables and factors established through factoring were used to construct the three-stratum Carroll model. (SLD)

Empirical support was derived for the multidimensionality of students' evaluations of teaching effectiveness on the Students' Evaluations of Educational Quality (SEEQ) through investigation of the factor structure of the SEEQ from 2 samples of 500 classes. Applications of confirmatory factor analysis and hierarchical factor analysis are…

Background: This study seeks to identify the cornerstones of personal bests (PBs) in the educational setting. Aims: The study proposes a multidimensional PB model in which students are most likely to attain PBs on tasks/goals that are (1) specific, (2) challenging, (3) competitively self-referenced, and (4) self-improvement based. Sample: The…

Social support from intimate and confiding relationships has received a great deal of attention; however, the study of the community as a relevant source of support has been comparatively lacking. In this article, we present a multidimensional measure of community support (Perceived Community Support Questionnaire, PCSQ). Through exploratory and…

Factor analyses of student evaluations of teaching effectiveness were conducted for 24,158 courses at the University of Southern California and for each of 21 different subgroups derived from the total group. All classes evaluated by six or more students were included in the study. The subgroups were designed to differ in terms of instructor level…

The question of whether test factor structure is indicative of the test item hierarchy was examined. Data from 1,000 subjects on two sets of five bivalued Law School Admission Test items, which were analyzed with latent trait methods of Bock and Lieberman and of Christoffersson in Psychometrika, were analyzed with an ordering-theoretic method to…

Empirical results from two studies--a simulation study and an experimental one--indicated that, in achievement data of the problem-solving type where a specific subject matter area is being tested, the greater the variety of the algorithms used, the higher the dimensionality of the test data.
