Confirmatory multidimensional item response theory (CMIRT) was used to assess the structure of the Graduate Record Examination General Test, about which much information about factorial structure exists, using a sample of 1,001 psychology majors taking the test in 1984 or 1985. Results supported previous findings that, for this population, there…

This study investigated changes in organization and crystallization of self-concept that may occur during early school years. Three models from self-concept literature that address early childhood development of self-concept are briefly described. Hypotheses are predicted on the assumptions that: (1) changes should manifest themselves between…

This study examines the nature of the highly variable black-white difference across diverse tests and indicates the major systematic source of this between-population variation, namely, Spearman's g. Eleven large-scale studies (discussed in the appendix), each one comprising anywhere from 6 to 13 diverse tests, show a significant and substantial…

Age and sex effects in multiple dimensions of self-concept were examined in responses by 3,562 preadolescent students (grades 2 to 6) to the Self Description Questionnaire (SDQ). A factor analysis of responses clearly identified the seven facets of self-concept which the SDQ is designed to measure: physical ability, physical appearance, peer…

Different aspects of the mentoring process as reflected in Carter's Mentor Scale (1983) were studied. The scale is composed of 16 statements of mentoring behaviors, including the following functional roles for mentors: role model, emotional supporter/counselor, sponsor, and evaluator. Attention was directed to the following questions: whether the…

Two bootstrapping or resampling strategies were investigated to determine their applicability to estimating standard errors and ensuing confidence intervals on variance components in two-factor random analysis of variance models. In light of prior negative findings regarding the application of bootstrapping to this particular problem, a…

The usefulness of the general Rasch model for multidimensional data, from the most simple formulations to the more complex versions of the model, is explored. Also investigated was whether the parameters of the models could be readily interpreted. Models investigated included: (1) the vector model; (2) the product term model; (3) the vector and…

While prior research has focused on death anxiety in general, more recent studies have recognized the need for multilevel measures for assessing the fear of death. A 12-item questionnaire was used to produce three factors: evaluation of death in general, belief in the hereafter, and death anxiety related to self. The study sample consisted of 901…

Since the Hawthorne Studies gave birth to the human relations approach to management, employee motivation, defined as an intervening variable(s) that accounts for factors within an individual that arouse, maintain, and channel behavior toward a goal, has been of much interest. An attempt was made to replicate the factor structure of the Wherry and…

Traditionally, confirmatory factor analytic models are tested against a null model of total independence. Using randomly generated factors in a matrix of 46 aptitude tests, this approach is shown to be unlikely to reject even random factors. An alternative null model, based on a single general factor, is suggested. In addition, an index of model…

This report demonstrates the feasibility of covering a large number of classes in a single study that has both classification and selection applications. A job analysis of clerical and administrative positions in the Government of the U.S. Virgin Islands was accomplished by means of a single questionnaire comprised of 264 items of the following…

Growing interest in self-presentation has spawned several examinations of individual differences in the tendency to manage one's impressions, notably Snyder's attempt to identify skilled impression managers through self-monitoring and an associated monitoring device, the Self-Monitoring Scale (SMS). To further examine the SMS, factor analyses were…

Personality, environment, and the interaction between them have been suggested as the major factors accounting for career development. Students (N=283) were asked to respond to 28 items on a recently revised self-report instrument, the Career Factor Checklist (CFC), in order to establish the construct validity of the revised CFC and to investigate…

Fundamental Interpersonal Relations Orientation Behavior Scale for Children (FIRO-BC) is a self-report measure of 9- through 13-year-old children's interpersonal behavior on six dimensions: expressed-inclusion, wanted-inclusion, expressed-control, wanted-control, expressed-affection, and wanted-affection. This investigation examined the factor…

Based on statistical data submitted by almost 3,000 academic libraries as part of the 1978-1979 Higher Education General Information Survey (HEGIS), this report develops a composite profile of an academic research library. Use of cluster analysis of library characteristics to find institutions that were quantitatively similar to one another…
