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…

A study integrated the major propositions of 2 theories of college persistence (Tinto's and Bean's) and used the resulting framework to survey a population of 466 first-year college students at 1 university. Findings supported most of the hypothesized links between the models and revealed a complex role for environmental factors in retention.…

Examined relation between fathers' and children's communicative skills and child behavior problems early and late in the Head Start school year. Found that the structural models for externalizing and internalizing behavior confirmed the hypothesis that father communication was linked to child communication skills and child communication was linked…

Studied the mechanisms by which social competence may be associated with substance use during early adolescence in a sample of 1,568 rural junior high school students. Structural equation modeling indicated that social competence had a direct protective association with substance use. Discusses mediating factors. (SLD)

This article describes a SAS macro to assess model fit of structural equation models by employing a test of the model-implied vanishing tetrads. Use of this test has been limited in the past, in part due to the lack of software that fully automates the test in a user-friendly way. The current SAS macro provides a straightforward method for…

Quality of life (QOL) is considered as a global, yet unidimensional, subjective assessment of one's satisfaction with life. We examine the construct validity of the available indicators of global QOL by constructing a causal model in which QOL is viewed as causally responding to several dimensions of perceived health. Global QOL is measured with…

Background: Contemporary research conducted in the context of school physical education (PE) has increasingly embraced various tenets of self-determination theory (Deci & Ryan, 1985, 1991). Despite this increase in research attention, some postulates of the framework remain unexplored (e.g. impact of a need-supportive climate). As such, the…

The influence of ethnic identity, acculturation, and mattering on wellness was examined for 176 minority and 286 non-minority adolescents attending a public high school. Participants completed the Multigroup Ethnic Identity Measure, the Stephenson Multigroup Acculturation Scale, the General Mattering Scale, the Mattering to Others Questionnaire,…

Latent growth curve modeling provides a powerful and flexible tool for researchers to study individual differences in change as well as the correlates and predictors of change. Recent developments in estimation and hypothesis testing procedures are largely based on confirmatory structural equation approaches. In this article, an alternative…

This study examined the mediating role of affect regulation among attachment, negative mood, and interpersonal problems. Participants were 229 college students at a large midwest university. Structural equation modeling indicated attachment anxiety and avoidance contributed to negative mood and interpersonal problems through different and distinct…

The biasing effects of measurement error in path analysis models can be overcome by the use of latent variable models. In cases where path analysis is used in practice, it is often possible to use parcels as indicators of a latent variable. The purpose of the current study was to compare latent variable models in which parcels were used as…

With increases in the use of structural equation modeling (SEM) in the social sciences, graduate course offerings in this statistical technique can be expected to increase. Knowledge of the content of current SEM course offerings may provide ideas to instructors developing new courses or enhancing current courses. This article discusses results…

Statistical methodology for handling omitted variables is presented in a multilevel modeling framework. In many nonexperimental studies, the analyst may not have access to all requisite variables, and this omission may lead to biased estimates of model parameters. By exploiting the hierarchical nature of multilevel data, a battery of statistical…

Both structural equation modeling (SEM) and item response theory (IRT) can be used for factor analysis of dichotomous item responses. In this case, the measurement models of both approaches are formally equivalent. They were refined within and across different disciplines, and make complementary contributions to central measurement problems…

A conceptual model for evaluating community-based program sustainability is presented, along with a 53-item Program Sustainability Index (PSI). Structural equation modeling (SEM) and principal axis factor analysis indicate strong support for each of the seven elements of the PSI. When considered as an overall model, six of the seven framework…
