This study tested a model of the effects of different predictors on individuals' levels of fear of crime in Dallas neighborhoods. Given its dual focus on individual perceptions and community-level interactions, social capital theory was selected as the most appropriate framework to explore fear of crime within the neighborhood milieu. A structural…

This paper presents a new polychoric instrumental variable (PIV) estimator to use in structural equation models (SEMs) with categorical observed variables. The PIV estimator is a generalization of Bollen's (Psychometrika 61:109-121, 1996) 2SLS/IV estimator for continuous variables to categorical endogenous variables. We derive the PIV estimator…

This investigation examined the impact combinations of at-risk factors had on 10,373 high school students in an urban school district from the school years 2000-2001 to 2006-2007. Students were categorized as high school graduates or dropouts. At-risk factors were associated with each student record. Hypothetical structural models were created for…

The purpose of this study was to empirically examine college graduate, faculty, and human resource manager descriptions of needed, received, and further training in eight employability dimensions of literacy and numeracy, critical thinking, management, leadership, interpersonal, information technology, systems thinking skills, and work ethic…

The present study investigated how maternal HIV and mediating family processes are associated with adolescent distress, substance use, and risky sexual behavior. Mother-adolescent (ages 12-21) dyads (N = 264) were recruited from neighborhoods where the HIV-affected families resided (161 had mothers with HIV). Mediating family processes were youth…

This study uses an ecological systems framework to examine how indicators of individual, family, and school contexts are associated with post-secondary educational enrollment among a sample of rural youth. Structural equation modeling allows us to examine both direct and indirect effects of these contexts on school enrollment. Unique elements of…

Recent literature on the determinants of academic motivation has shown that parenting and emotions are central elements in understanding students' achievement goals. The authors of this study set out to examine the predictive relationship between parental behaviors during the last year of elementary school and adolescents' achievement goals at the…

Makes the case that the Raykov and Marcoulides Proof (RMP; T. Raykov and G. Marcoulides, 2001) generalizes to a broad class of structural equation (SE) models. Suggests a counterexample that accepts the statistical dimensions of the RMP while questioning the conclusion, highlighting the need for greater attention to the semantic dimension of SE…

Discusses issues in structural-equation-model selection that pertain to the general utility of the principle of parsimony. Provides an example using data generated by the relatively nonparsimonious simplex model and fitted rather well by a parsimonious growth-curve model belonging to a different class of models. (Author/SLD)

A procedure is proposed to generate non-normal data for simulation of structural equation models. The procedure uses a simple transformation of univariate random variables for the generation of data on latent and error variables under some restrictions for the elements of the covariance matrices for these variables.

Early coital debut is a risk factor for HIV. In this paper we investigate the predictors of young adolescents' transition to first intercourse using a social cognition theoretical framework. The analyses reported here were based on a longitudinal study of 2360 students in the schools allocated to the control arm of a cluster-randomized controlled…

We examine the prediction of individuals' educational and occupational success at age 48 from contextual and personal variables assessed during their middle childhood and late adolescence. We focus particularly on the predictive role of the parents' educational level during middle childhood, controlling for other indices of socioeconomic status…

The purpose of this study was to explore how social support, mother's psychological status, and maternal sensitivity affected attachment security in children with disabilities by using the structural equation model (SEM). Subjects were 141 pairs of children with disabilities and theirs mothers. Empirical data was obtained through a series of…

In recognition of the multiple pathways through which family and peer systems are linked, this short-term longitudinal study tested a tripartite model of family-peer relationships. One hundred fifty-nine fourth-grade children (82 boys, 77 girls) and their parents participated in a study of the links between parent behaviors and children's peer…

In this study, two longitudinal models of early adolescent risky sexual behaviors (RSB) were compared using a pooled sample of 267 Canadian and Italian adolescents (55% females; 53% Canadians) assessed yearly from grade 8 to 10. We focused on parenting practices (monitoring, control, limit setting), adolescent problem behaviors (antisocial…
