Scores from a revised version of the School Level Environment Questionnaire (SLEQ) were validated using a sample of teachers from a large school district. An exploratory factor analysis was used with a randomly selected half of the sample. Five school environment factors emerged. A confirmatory factor analysis was run with the remaining half of…

Background: Previous research suggests a link between inter-parental conflict and children's psychological development. Most studies, however, have tended to focus on two broad indices of children's psychological adaptation (internalizing symptoms and externalizing problems) in considering the effects of inter-parental conflict on children's…

This study investigated a measurement model of personality resilience and the contribution of personality resilience to lower achieving first grade students' academic achievement. Participants were 445 ethnically diverse children who at entrance to first grade scored below their school district median on a test of literacy. Participants were…

The authors examined circumplex models of interest structure across time (Grades 8, 10, and 12), gender, and analytic method in a secondary analysis of vocational interest type (Realistic, Investigative, Artistic, Social, Enterprising, and Conventional) data generated from the American College Testing database (national sample of 69,987 students).…

Using latent variable structural equation modeling, we tested a theoretical model positing that grade retention has a positive effect on children's teacher- and peer-rated academic competencies and on sociometric measures of peer acceptance. We also expected that the positive effect of grade retention on peer acceptance would be mediated by…

A Monte Carlo study was conducted to assess the effects of some potential confounding factors on structural equation modeling (SEM) fit indices and parameter estimates for both true and misspecified models. The factors investigated were data nonnormality, SEM estimation method, and sample size. Based on the fully crossed and balanced 3x3x4x2…

This study was conducted to investigate the dimensionality of language tests by means of latent variable models for categorical data. It differs from previous studies by conducting the analysis at the level of the original items using the structural modeling approach of B. Muthen (1984) for dichotomous and ordered polytomous variables. In this…

Basic philosophical and statistical issues in structural equation modeling (SEM) are reviewed, including model conceptualization, identification, and parameter estimation and data-model-fit assessment and model modification. These issues should be addressed before the researcher uses any of the new generation of SEM software. (SLD)

The distribution of technical and substantive structural equation modeling (SEM) articles published in psychological journals from 1987 to 1994 was studied through inspection of more than 1,050 abstracts in the "PsycLIT" system. There has been a clear increase in the number of journals and the number of substantive SEM articles. (SLD)

Data on academic self-concept, school grades, and teacher ratings of achievement were collected from 603 students for three high school subjects in each of three years. Structural equation models show reciprocal effects for prior achievement and academic self-concept for all subjects. Effects were largest for mathematics. (SLD)

A computationally efficient three-stage estimator of thresholds and covariance structure parameters is prepared for analysis of structural equation models with polytomous variables. The method is based on partition maximum likelihood and generalized least squares estimation. An analysis of questionnaire responses of 739 young adults illustrates…

Using an approach to the analysis of missing data, this study investigated developmental trends in alcohol, marijuana, and cigarette use among 750 adolescents across 5 years using multiple-group latent growth modeling. Latent variable structural equation modeling and missing data approaches to studying developmental change are explored. (SLD)

A study at the University of Tennessee Knoxville used mixed-effect structural equation models incorporating latent variables as an alternative to conventional methods of analyzing college students' (n=722) first-year-to-senior academic gains. Results indicate, contrary to previous analysis, that coursework and student characteristics interact to…

A two-stage approach based on the rationale of maximum likelihood and generalized least-squares methods is developed to analyze the general structural equation model for continuous and polytomous variables. Some illustrative examples and a small simulation study (50 replications) are reported. (SLD)

Three psychophysical auditory processing tests, varying in emphasis on speed of processing and pitch discrimination, and tests of verbal and nonverbal ability were administered to 108 13-year olds. A structural equation model suggests that information processing speed and pitch discrimination ability are significantly associated with nonverbal and…
