A review of the research into the second-order factor structure of the 16 Personality Factor Questionnaire (16 PF) indicates disagreement about the number and meaning of the second-order factors. However, repeated analyses of the second-order factor structure have consistently found fewer than the eight factors suggested by Catell (1973) and the…

The classification of intelligence has been a prime interest to many for over three-quarters of a century. The Wechsler scales of intelligence and the development of factor analysis have both played major roles in the shaping of psychometric thought. An examination of this joint history by means of a review of the factor analytic studies of the…

Most patients with diagnosable major depression may fail to show the classic symptom pattern for which standard assessment instruments were designed. To investigate the influence of subtype of depressive illness on Zung Self-Rating Scale (SDS) and Hamilton Rating Scale (HRS) validity, 36 in-patients, who met Diagnostic and Statistical Manual…

Overall findings were interpreted from a developmental perspective, and the data were shown to offer evidence for the contruct validity of the MSCA. (Author/RC)

Few methods have been tried and used to graphically represent more than two variables. This poster session showed a new method for representing three continuous variables on a single scatterplot using the THREEDE computer program. Two variables are represented as a normal bivariate distribution. The third variable is represented by a symbol, e.g.…

The purpose of this study was to replicate the study conducted by Potter, Sagraves, and McDonald to determine whether their recommended analysis could separate criterion variables into similar factors that were stable from year to year and from school to school. The replication samples consisted of all students attending Louisiana State University…

Readiness skills of 1,261 kindergarten students were assessed with the use of the Kindergarten Instructional Design System (KIDS). The profile provides assessment in five areas: Motor, Visual, Auditory, Language, and Conceptual. Two statistical techniques were utilized to examine the underlying structure of the measure: factor analysis and…

Although depression is considered to be common in the elderly, reliable rates of prevalence are lacking. Studies have shown that age differences on measures of depressive symptomatology can be attributed to higher levels of somatic complaints. In order to examine whether the association between somatic and depressive symptoms varies as a function…

Based on Leviton and Hughes' conceptualization of variable clusters that affect evaluation utilization, a procedure for measuring utilization potential was developed. Five clusters of variables are consistently related to utilization: relevance, credibility, communication, information processing, and user involvement and advocacy. The…

A factor analysis, using the varimax rotated procedure, was conducted on Bem Sex-Role Inventory (BSRI) data from a random sampling of the national physical education organizations mailing list of physical education teachers. Of 458 potential respondents, 302 returned questionnaires, of which 298 complete questionnaires were used in the analysis.…

An earlier version of this paper was presented at the annual meeting of the American Sociological Assoc. (San Francisco, Calif., Aug. 29, 1967)

Two perspectives provide the theoretical framework for this study. The first provides confirmatory maximum likelihood estimates of factor loadings and factor intercorrelations; the second, and more important, provides statistical tests of hypotheses that factor structures and patterns of values are invariant for female and male adolescents. The…

Factor analysis can be a valuable tool for assessing validity; however, the reliabilities of identified factors must be attended to. This study examined the impacts of item variance on factor stability and structure. The attempt was to determine empirically whether unnumbered graphic scales scored using a larger number of scale steps produce more…

In the area of large scale assessment, there is increasing interest in the measurement of students' written performance. At issue is whether the task demands in writing assessment can be simplified to involve the production of paragraph-length writing samples and/or multiple choice testing, rather than full-length essays. This study considers data…
