There is a lack of research on the effects of outliers on the decisions about the number of factors to retain in an exploratory factor analysis, especially for outliers arising from unintended and unknowingly included subpopulations. The purpose of the present research was to investigate how outliers from an unintended and unknowingly included…

Classroom context and climate are inherently classroom-level (L2) constructs, but applied researchers sometimes--inappropriately--represent them by student-level (L1) responses in single-level models rather than more appropriate multilevel models. Here we focus on important conceptual issues (distinctions between climate and contextual variables;…

This article examines the psychometric structure of the Anxiety Control Questionnaire (ACQ) in Chinese adolescents. With the data collected from 212 senior high school students (94 females, 110 males, 8 unknown), seven models are tested using confirmatory factor analyses in the framework of the multitrait-multimethod strategy. Results indicate…

Over 600 White females between 10.5 and 18.5 years of age were studied to test construct comparability across adolescence. Assessed were emotional functioning, eating problems, self-reflection, self-image, and mastery/adjustment to examine meaning equivalence in self-concepts and developmental psychopathology. Results suggest that the five factors…

A very general model for the computation of independent cluster solutions in factor analysis is presented. The model is discussed as being either orthogonal or oblique. Furthermore, it is demonstrated that for every orthogonal independent cluster solution there is an oblique analog. Using three illustrative examples, certain generalities are made…

Through use of confirmatory maximum likelihood factor analysis in conjunction with the LISREL V computer program, an evaluation was made of the validity of higher-order ability constructs in structure-of-intellect tests all containing semantic content and operations of cognition or evaluation.

AN ATTEMPT WAS MADE TO DETERMINE THE EFFECTS OF CERTAIN VARIATIONS IN METHODOLOGY ON THE ANALYSIS OF EXISTING SETS OF DATA IN THE AREAS OF ABILITY OR INTELLIGENCE AND MOTOR PERFORMANCE OR PHYSICAL FITNESS. USING CURRENT DEVELOPMENTS IN THEORY AND METHODS OF FACTOR ANALYSIS DIFFERENT TREATMENTS OF VARIOUS SETS OF DATA, THREE RELATIVELY NEW MODELS…

The purpose of the study was to use confirmatory factor analysis techniques to assess the adequacy of previous validity studies related to the structural and theoretical dimensions underlying a measure of self-concept, the Piers Harris Children's Self Concept Scale. Responses from 890 students in grades 3-6 were used as input to the LISREL program…

Working from a common data base and hypothesized model, this paper demonstrates and compares the EQS and LISREL computer program strategies in the analysis of a second-order factor model. Program similarities and differences are noted with respect to: (1) preliminary analyses of the data; (2) treatment of data that are not multivariately normal;…

Findings are reported for a cross-validated study of factorial validity and invariance of the Maslach Burnout Inventory across gender for elementary school teachers (742 males and 801 females) and secondary school teachers (659 males and 721 females). The study illustrates structural modeling methodology and use of multiple model-fitting criteria.…

The purpose of the present investigation is to study the hierarchical structure of academic self-concept. The original Shavelson model posited specific facets of academic self-concept to define a single higher-order facet, but Marsh and Shavelson (1985) found the hierarchical structure to be more complicated. In a revised model they proposed that…

This investigation: (1) tested the ability of an a priori hierarchical structure of self-concept derived from the Shavelson model to explain responses to the Self Description Questionnaire III (SDQ III); and (2) demonstrated the application and problems with the use of hierarchical confirmatory factor analysis. A first-order factor analysis…
