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…

The psychometric properties of the Frost, Marten, Lahart, and Rosenblate Multidimensional Perfectionism Scale (1990) are investigated to determine its usefulness as a measurement of perfectionism with Australian secondary school girls and to find empirical support for the existence of both healthy and unhealthy types of perfectionist students.…

This study provides evidence of reliability and validity for the Leisure Interest Questionnaire (LIQ; J. C. Hansen, 1998). Undergraduate students completed the LIQ and Strong Interest Inventory (SII; E. K. Strong Jr., 1927) at Time 1 and the LIQ 5 weeks later. The internal consistency and test-retest reliability of the LIQ scales were calculated.…

The Psychological well being Inventory (PWBI) is a multidimensional instrument that has enjoyed widespread use in a variety of research initiatives, from small-scale studies to national surveys. Recent empirical investigation of the measure has raised questions about its validity. This study examines the factorial validity of the Environmental…

A study was conducted to determine the dimensions underlying the items on a course-instructor survey instrument currently in use to measure graduate student ratings of instruction (attached). Both factor analysis and multidimensional scaling methods were used to analyze the response data, so that the results of each could be evluated, and the two…

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)

Multidimensional scaling (MDS) and components solutions were compared using two balanced self-report item sets. Results suggest that when self-report items are balanced and negatively worded items are not reverse scored, MDS and components solutions can differ largely, due to a component associated with measures of acquiescence.

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 purpose of the paper is to determine whether test forms of the Mathematics Usage Test (AAP Math) of the American College Testing Program are parallel in a multidimensional sense. The AAP Math is an achievement test of mathematics concepts acquired by high school students by the end of their third year. To determine the dimensionality of the…

Several methods for estimating item response theory scores for multiple subtests were compared. These methods included two multidimensional item response theory models: a bi-factor model where each subtest was a composite score based on the primary trait measured by the set of tests and a secondary trait measured by the individual subtest, and a…

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)

Two divergent views are contrasted: the multidimensional and the unidimensional views of faculty evaluation. The views of H. W. Marsh, the most outspoken advocate of the multidimensional view of evaluation based on factor scores, is summarized and a response to his concerns is presented. (Author/MLW)

Two aspects of the reliability of multidimensional measures can be distinguished: the amount of scale score variance that is accounted for by all underlying factors (composite reliability) and the degree to which the scale score reflects one particular factor (construct reliability). Confidence intervals for composite and construct reliabilities…

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…
