When William G. Perry (1968) developed his scheme of nine stages of cognitive development, most of which are experienced during the college years, he did not attempt to quantify it. Subsequently, T. D. Erwin (1983) constructed a scale that attempted to quantify the Perry scheme. His findings supported the overall conception of student development…

The Child Behavior Checklist (CBCL) is used to assess the behavioral problems and social competencies of children. Its broad usage in both practitioner and research contexts has led to misapplications as compared to the CBCL's original intended purpose. In addition, the composition of the normative sample presents particular difficulties for…

In the last 10 years, women's gender-equity reports have increased in number. Some theorists perceive quantitative procedures as "masculine" and qualitative procedures as "feminine." To refute this dichotomy, over 200 equity research reports produced between 1981 and 1991 were examined in a mini-meta analysis to identify the…

The following seven statistical procedures are compared in terms of the ability to recover a unidimensional latent trait from Likert-type data: (1) factor analysis based on Pearson correlations (FA-PR); (2) factor analysis based on polychoric correlations (FA-PL); (3) the graded response model in item response theory (IRT-GRM); (4) internal…

The development and initial validation of a new self-report instrument, the Differentiation of Self Inventory (DSI), are presented. The DSI represents the first attempt to create a multidimensional measure of differentiation based on Bowen Theory, focusing specifically on adults (aged over 25 years), their current significant relationships, and…

This study examined the construct validity of the Rod and Frame Test (RFT). Subjects were 554 clients (269 males and 285 females) (aged 14 to 65 years) of the Johnson O'Connor Research Foundation (JOCRF), a vocational guidance service. In a battery of diverse ability and style tests (19 tests of the JOCRF battery and 4 tests of cognitive style),…

This study investigates the Computer Attitude Scale (CAS) in terms of reliability, factorial validity, and fit to a unidimensional model. The sample for this study consisted of 265 teachers from 20 schools and school districts in one state who attended evening and weekend classes that emphasized teachers teaching teachers about classroom…

Extending research on the Marsh/Shavelson model of self-concept, a set of 14 academic self-concept scales was related to school performance in 8 school subjects for a sample of 507 high school students. Correlations between matching areas of self-concept and achievement (0.45 to 0.70; mean r=.57) were substantial and larger than correlations…

In recent years, standardized test scores have assumed an increasingly important role in educational assessment. As the stakes involved in testing become higher, educators are forced to make decisions regarding the ethics involved in standardized test preparation and administration. The ethical continuum of test preparation practices as formulated…

Psychometric information was determined for two scales commonly used in early intervention programs and research, the Family Support Scale (FSS) (C. J. Dunst and others, 1984) and the Family Resource Scale (FRS) (C. J. Dunst and H. E. Leet, 1985). These questionnaires measure the perceptions of support for families with children with disabilities…

The robustness of a partial credit (PC) model-based computerized adaptive test's (CAT's) ability estimation to items that did not fit the PC model was investigated. A CAT program was written based on the PC model. The program used maximum likelihood estimation of ability. Item selection was on the basis of information. The simulation terminated…

Ego development data were collected from two groups of subjects. One group consisted of 175 students from junior high, senior high, and college. The second group was comprised of 136 adults who were either teachers and administrators of a medium-sized public school system, or long-time employees of a large chemical manufacturing corporation.…

This study of school effects included unique teacher and principal variables: average faculty score on the National Teacher Examinations (NTE) Commons and area examinations, mean passing rate on the NTE of institutions the faculty attended, principal's percentile score on the NTE administration test, and principal's rating on school district…

This second volume of the final report contains the statistical tables, coding key, and the rating manual for the coding key. Data on interrater reliability, factor analyses, and discriminant analyses are included and described. The manual for the coding key includes the data base and/or criteria for each item to be coded.

A latent trait model is described that is appropriate for use with tests that measure more than one dimension, and its application to both real and simulated test data is demonstrated. Procedures for estimating the parameters of the model are presented. The research objectives are to determine whether the two-parameter logistic model more…
