Proposes a model of kindergartners' development of literacy resources. States that, throughout the year, kindergartners completed tasks similar to those typically used in their different instructional programs, and factor analysis identified five factors for use in a path analysis. Finds various factors influenced outcome variables, represented by…

Discusses linear structural relations, Two Stage Least Squares, and path analysis as statistical procedures that sometimes permit causal inferences from correlational findings. Even though two variables cannot be interpreted causally due to a possible but unknown third variable, these methods are appropriate for handling models with correlated…

The study proposes using path analysis and residual plotting as methods supporting environmental scanning in strategic planning for higher education institutions. Path models of three levels of independent variables are developed. Dependent variables measuring applications and enrollments at Virginia Polytechnic Institute and State University are…

Using time-lagged research design and path analysis, findings from 132 college faculty supported the conservation of resources model, which predicts that, as chronic work and family stressors drain resources, dissatisfaction and life distress increase and health declines. Self-esteem was not a moderating variable. (SK)

Describes a study of students in grades three, four, and five that tried an educational application derived from the social constructivism view based on theories of Vygotsky and Piaget to improve cognitive development in a heterogeneous class. Path analysis showed that complex learning techniques are related to cognitive development. (Author/LRW)

Multicollinearity is a well-known general problem, but it also seriously threatens valid interpretations in structural equation models. Illustrating this problem, J. Pietsch, R. Walker, and E. Chapman (2003) found paths leading to achievement were apparently much larger for self-efficacy (.55) than self-concept (-.05), suggesting--erroneously, as…

Harry Stack Sullivan maintained that competition between friends in early adolescence would generally destroy their friendship. Working with early adolescent samples in Canada, Costa Rica, and Cuba, we found that hypercompetitiveness--a form of competition involving the need to prove one?s own superiority--was linked with conflict between friends,…

This study examines the process whereby functional disability amplifies depressive symptoms through decreasing perceived social support and psychological resources. The study analyzed two waves of panel data (1986 to 1992) of a large sample of older adults from the National Institutes of Aging Established Populations for Epidemiologic Studies of…

To steer a course through the world, people are almost entirely dependent on visual information, of which a key component is optic flow. In many models of locomotion, heading is described as the fundamental control variable; however, it has also been shown that fixating points along or near one's future path could be the basis of an efficient…

This paper reports on a study that examined both the concurrent and longitudinal connections between multiple components of the home environment and indicators of preschool-aged children's literacy and language development. Data were collected from 85 parents and their children at two different times. Results of structural path models indicated…

Objective: The potential path from sexual abuse as a child to the current risk of physical abuse by mothers was assessed. Ontogenic variables including the experience of the parent's sexual abuse as a child and current depression or substance abuse were expected to have a greater impact on the risk of child abuse than microsystem and exosystem…

This book is meant as a basic and fairly nontechnical introduction to multilevel analysis for applied researchers in the social sciences. The term "multilevel" refers to a hierarchical or nested data structure, usually people within organizational groups, although the nesting may also consist of repeated measures with people or…

This paper tests a multivariate theory of family status, socialization, and student politics employing two different methodological techniques: (1) the popular path analysis method as compared with (2) a modified causal analysis approach. Results reveal that both techniques appear to be a reliable check on one another. (Editor/PG)

In an analysis of multitrait-multimethod matrices the criteria for discriminant validity are shown to include a "structure" criterion as an invariance of traits structure to methods. The criterion is meant to fit data to an additive model with traits and methods but not interaction terms. The importance of the structure criterion and the…

School interventions are often based on the assumption that such variables as self-concept and locus of control should have a meaningful impact on achievement. Yet research support for such influence is inconsistent. Because this inconsistency may be due to methodological problems, a study was conducted which used path analysis to determine the…
