Attempts to determine whether different types of MMPI (Minnesota Multiphasic Personality Inventory) profiles occur for heroin abusers and, if they existed, to describe them. (Author/RK)

Thirteen statements were all linked to one or more empirical studies found in the instructional methodology literature. The students completed a voluntary survey that contained demographic questions and 13 empirically linked statements on teaching practices students "believed helped them learn better." A Promax (Oblique) rotation revealed three…

This paper reports the results of an analysis of a reading comprehension test using the Q subscript 3 (Q3) statistics developed by W. Yen (1984). Yen's Q3 can be a useful tool for examining local item dependence in the context of a reading comprehension test in which a set of related items is followed by a reading passage. Q3 is basically a…

The factor make-up of the Protestant Work Ethic, first presented by M. Weber, was explored, and the relationship between endorsement of the Protestant Work Ethic and academic achievement was studied in a sample of 257 high school seniors. The independent variable was level of endorsement of the Protestant Work Ethic. The dependent variable was…

Because ignoring the missing data in an evaluation may lead to results that are questionable, this study investigated the effects of use of four missing data handling techniques on a survey instrument. A questionnaire containing 35 5-point Likert-style questions was completed by 384 respondents. Of these, 166 (43%) questionnaires contained 1 or…

This study described an explicit multidimensional scaling (MDS) model for profile data, the Profile Analysis via Multidimensional Scaling (PAMS) model. It also illustrated the application of this model to the study of the structure of cognitive ability patterns using the Woodcock-Johnson Psychoeducational Battery-Revised (WJPB-R; 1989; 1991) and…

Two studies focused on the reliability and validity of T.M. Singelis's 24-item Self-Construal Scale (SCS) (1994). In the first study, Cronbach alphas were calculated to assess the internal consistency of the reliability of the two subscales that were supposed to measure individuals' independent and interdependent self construals. The sample was…

The primary goal of this study was to investigate the underlying structure of the Differential Ability Scales (DAS) using Exploratory Principal Axis Factoring (PAF) with 62 nonclinical preschoolers. While previous factor analyses of the DAS Core subtests revealed the derivation of two distinct factors, the current results revealed only one factor,…

A cross validation study was conducted using data from white, rural seventh graders to investigate the stability of the construct validity of a model of eight conditions that are purported to support adolescent academic aspirations. A factor analytic study examined GEAR-UP survey data from 4,365 students across two consecutive years. In…

Studied relationships between self-concept measures of disadvantaged mothers and their children, using canonical and factor analyses. (DP)

The purpose of the present study was to determine to what extent the results of Smith's test can be generalized to other essay rating situations. The test measured teachers' attitudes about the characteristics of good writing. (Author/RK)

In this article, the author discusses the application of factor analysis as a technique in the investigation of multidimensional educational problems and presents the results of one such application. (Editor)

The JEPI was re-analysed by item, factor and cluster analysis. (Editor)

A rationale is provided for hypothesizing that a counterpart of the social desirability variable influences environmental ratings based on student perceptions, and a test is made of the hypothesis. (Editor)

Special cases of the factor analysis model are developed for four selection situations. Methods are suggested whereby parameters in each case can be estimated using a maximum likelihood procedure recently developed by Joreskog. (Author)
