Rotation of canonical components is contrasted with factor rotation and the concept of communalities in canonical analysis is considered. Three possible strategies for rotating canonical components are described: single rotation of all components, separate rotation of each set, and sequential rotation of one set then the other. Constraints,…

A general purpose computer program for the calculation of a matrix of tetrachoric correlations is described. This program was developed for use in adaptive (and other) testing research for examining the unidimensionality assumption in latent trait theory, in conjunction with available factor analysis programs. Several other potential applications,…

The purpose of this study was to examine the relationship of the variables of intelligence, creativity, and a language component in preschool disadvantaged Negro children. Major hypotheses were: (1) that the specific components of each variable had higher correlations within each variable than between variables; and (2) that each major loaded on a…

It was the purpose of this study to ascertain whether the culturally disadvantaged child, who appeared to adhere to the principle of immediate gratification, had learned, as a function of his participation in Head Start, a more future-related orientation when compared to his non-Head Start counterparts. One hundred and eighty-seven 4- and…

An earlier report presented the results of an inverse factor study of interrelationships among students over a variety of measures associated with motivation to study in college. Seven of the 10 motivational factors revealed in that study were related to academic criteria that are considered to be of practical importance in the admissions process.…

During the fall term, preliminary forms of the Experimental Method Test (EMT) were given to introductory level psychology students as well as a number of advanced students. The results of this preliminary testing led to the development of a second form of the test which was evaluated over a number of groups of students. The results of the final…

A factor analysis was performed of education goal ratings of principals, teachers and parents of a number of California elementary schools. One hundred and six goals obtained from the Center for the Study of Evaluation's Needs Assessment Kit were rated on a five point scale for their importance. Ratings were submitted to a principal components…

The study explores the reasons for the resignation from the United States Army among graduates of the United States Military Class of 1966. It seeks to determine reasons for resignations, quality of resignees compared with nonresignees, and what can be done to reduce resignations of Academy graduates. Through questionnaires and personal…

This report is part of a general study of Reference Measures for Cognitive and Noncognitive Factors. The specific activity that is being reported is the development of "factor-referenced" tests or "marker" tests for several cognitive factors related to divergent production (i.e., ability to produce a variety of words, phrases,…

This study describes behavioral response--both its theoretical specification and its estimation--which relates health service utilization and expenditures to a number of variables: demographic, psychological, economic, medical, and policy-related. By incorporating these behavioral relations into a recently developed microsimulation model, national…

This inquiry determines the degree of relationship between observed faculty personal characteristics and judged teaching effectiveness. Students in a liberal arts college rated faculty on two typical teaching evaluation instruments and on a semantic differential form. Data came from 1,500 student judgments on 108 faculty (86 percent). Factor…

This paper describes Personality and Educational Environment Scales (PEES) and a self-concept theoretical model, used in diagnosing dropout from educational institutions, as utilized in a follow-up study of participation and dropout in adult education classes. A dropout was defined as a person who after being present for session 1 or 2 was absent…

In this paper a rather general theory of oblique factor rotation is outlined. The main results are formulated as four theorems. Necessary and sufficient conditions are derived for two factor matrices to admit identical factor structures and/or factor patterns with factors having unit variances. These conditions are expressed in terms of…

A new general approach to the problem of oblique factor transformation is identified and presented as an alternative to the common "blind" transformation techniques currently available. In addition, techniques for implementing such an approach are developed. The first section of the paper contains a brief review of the procrustes problem. The next…

The purpose of this research study was to develop and test new instruments for assessing attitudes and coping responses to air pollution, and to gain insight into the factors influencing these attitudes and coping responses. Concern for air pollution was measured by two instruments a forced choice questionnaire which paired air pollution control…
