Structural equation modeling was used to examine relationships among prewar factors, dimensions of war-zone stress, and current posttraumatic stress disorder (PTSD) symptomatology using data from 1,632 female and male participants in the National Vietnam Veterans Readjustment Study. Discusses research findings. Recommends more attention be given…

In this article, a heterogeneous latent growth curve model for modeling heterogeneity of growth rates is proposed. The suggested model is an extension of a conventional growth curve model and a complementary tool to mixed growth modeling. It allows the modeling of heterogeneity of growth rates as a continuous function of latent initial status and…

Guided by Self-Determination and associated theories, we examined whether adolescent (N=324, Mage=15, 52% female) competence (academic engagement and achievement) were supported by relationships at school and school fit. Aspects of relationships and school fit that were measured included adolescents' perceptions of each context as promoting…

This study investigated the effects of personality and career decision-making self-efficacy on progress in career choice commitment in a sample of 184 college students. It was hypothesized that self-efficacy would mediate the relationship between neuroticism and extraversion and career choice commitment. Results revealed significant differences…

This paper describes structural equation modeling (SEM) and possibilities for using SEM to address problems specific to workforce education and career development. A sample of adolescents identified as work-bound (i.e., transition directly from secondary school to work) from the National Education Longitudinal Study 1988-1996 database (NELS:…

In the present study, we used a model of motivation grounded in self-determination theory (Deci & Ryan, 1985, 1991; Ryan & Deci, 2000a, 2000b, 2002) to examine the relationship between physical education (PE) students' motivational processes and ratings of their effort and persistence as provided by their PE teacher. Data were obtained…

The present study outlines a specific three-level hierarchy of the cognitive system, in particular the relationship between cognitive and metacognitive processes in mathematics. The emphasis is on the impact of processing efficiency and working memory ability on the development of self-representation and mathematical performance. We developed and…

Background: Twin studies of childhood behavior problems support the conclusion that individual differences in impulsivity, hyperactivity, and inattention are largely due to genetic influences. Non-genetic variation is due to environmental influences that are unique to the individual, and possibly to rater contrast effects. In the present…

The question of whether creativity is content general or content specific is one of the most controversial issues in contemporary creativity research. Recent studies provide support for both positions, but the results of these investigations may be influenced by several factors, including the presence of a method effect (i.e., psychometric vs.…

Purpose: The environment provided by an organisation to facilitate learning and create knowledge has been defined as the shared organisational context. The value to an organisation of knowledge created by the shared organisational context is called intellectual capital, of which one key component is relational capital. The purpose of this paper is…

Concurrent and prospective associations between parent-youth dyadic hostility and adolescent externalizing and internalizing problem behavior were examined in a sample of 416 families. Parenting control, parents' well-being, and youths' affiliation with deviant peers were included as integral covariates. Information from multiple sources was…

This paper is about the structural equation modelling of quantitative measures that are obtained from a multiple facet design. A facet is simply a set consisting of a finite number of elements. It is assumed that measures are obtained by combining each element of each facet. Methods and traits are two such facets, and a multitrait-multimethod…

The current study examined the influence of symptoms of attention deficit hyperactivity disorder (ADHD) on student academic achievement in reading and in mathematics in a sample of 146 first- through fourth-grade students, 103 of which were identified as having ADHD and academic problems in reading and/or math. A theoretical model was examined…

A structural equation modelling analysis was used to test the mediating effect of achievement goal factors on the relationship between Egyptian adolescents' perception of parental involvement and academic achievement. The perception of Parental Involvement Scale and Achievement Goal Questionnaire was administered to a sample of 255 first-year…

The main purpose of the present study is to demonstrate the structure, mechanisms, and efficacy of community policing and its impact on perceived disorder, crime, quality of life in the community, citizens' fear, and satisfaction with the police. It compares traditional and community policing paradigms on three dimensions: goal, measurement of…
