Three proposed models were tested to explore the inter-relationships affecting student academic performance and nonacademic factors using structural equation modeling. Results with 147 undergraduates suggest that a Bio-Model and a Family Mediated Model serve to predict academic performance moderately well. (SLD)

An alternative two-stage least squares (2SLS) estimator of the parameters in LISREL type models is proposed and contrasted with existing estimators. The new 2SLS estimator allows observed and latent variables to originate from nonnormal distributions, is consistent, has a known asymptotic covariance matrix, and can be estimated with standard…

Provides an introduction to structural equation modelling (SEM) for language research, including: general objectives of SEM applications relevant to language assessment; methodology and statistical assumptions about data that must be met; commonly-used SEM steps and concepts; application matters, with sample models; and recent critical discussions…

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)

Examined relations between mothers' expressed positive and negative emotion and 55- to 79-month-olds' regulation, social competence, and adjustment. Structural equation modeling revealed unique effects of positive and negative maternal expressed emotion on children's regulation, and the relations of maternal expressed emotion to children's…

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…

This study compared the strength of competing causal models in explaining the relationship between perceived support, enacted support, and social anxiety in adolescents. The social causation hypothesis postulates that social support causes social anxiety, whereas the social selection hypothesis postulates that social anxiety causes social support.…

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…

Secure parental attachment and healthy levels of separation-individuation have been consistently linked to greater college student adjustment. The present study proposes that the relation between parental attachment and college adjustment is mediated by healthy separation-individuation. The authors gathered data on maternal and paternal…

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…
