College students rated dissimilarity of pairs of common test item formats. A multidimensional scaling model with individual differences fit to data from 111 students suggested that they used 2 dimensions to distinguish among the formats, 1 separating supply from selection items and 1 based on the number of options.

Evaluation of multidimensional measures of community adjustment in 239 young adults with mild to severe mental retardation resulted in development of a cross-validated model which found such broad dimensions of community adjustment as social network integration, recreation leisure integration, community and economic integration, and need for…

A model integrating latent trait and latent class theories in characterizing individual performance on the basis of qualitative understanding is presented. This HYBRID model is illustrated through experiments with 119 Air Force technicians taking a paper-and-pencil test and 136 Air Force technicians taking a computerized test. (SLD)

The current work examined age differences in the classification of novel object images that vary in continuous dimensions of structural shape. The structural dimensions employed are two that share a privileged status in the visual analysis and representation of objects: the shape of discrete prominent parts and the attachment positions of those…

The problem of dimensionality with respect to Raven's Advanced Progressive Matrices (APM) specifically and, more generally, "g" or fluid intelligence, has been a long-standing issue. The present article reports two studies examining the dimensionality of both the original Set II of the APM (n = 506) and a short form (n = 644), using principal…

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 authors examined how college men's conformity to an array of masculinity norms varied as a function of their vocational interests to better understand the gendered context of men's vocational development. Three hundred ten mostly Caucasian and heterosexual college men completed the Conformity to Masculine Norms Inventory, and their answer to…

A study involving 234 Texas college students was undertaken to develop and test the validity and reliability of an instrument designed to measure college students' attitudes toward alcohol. Special attention was given to the content and construct validity of the instrument. Subjects ranged in age from 18 to 24 years. The mapping sentence served as…

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 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…

Many researchers have suggested that the cause of differential item functioning (DIF) can in part be due to the misspecification of the supporting trait distribution (STD). This paper demonstrates how a unidimensional item response theory (IRT) calibration of response data, generated from a two-dimensional IRT model, results in DIF when the…

Depression therapy literature cites the importance of self-concept in formulating therapeutic strategies. Traditional depression measures catalog a client's symptoms, but fail to tap the structure of dysfunctional thoughts and judgments that form the client's self-concept. Vector-product multidimensional scaling was used to develop a measure of…

There still remains in our social institutions and individual lives a considerable splitting between feminine and masculine gender distinctions. The present study determined the dimensionality of the space of 53 admirable personality traits hypothesized to relate to femininity-masculinity and creativity, and assessed preferences of females versus…

Using a multidimensional scaling procedure, this study examined the fit of Holland's RIASEC hexagon model to the internal relationships among the Strong-Campbell Interest Inventory (SCII) General Occupational Theme scales. SCII intercorrelation matrices for both sexes as reported in the SCII Manual were submitted, separately for each sex, to…

A scale measuring attitudes toward small-group teaching was administered to 442 teachers from 28 elementary and secondary schools in Israel. At least two dimensions of attitudes were identified: control over class and efficiency of the method. (Author/JKS)
