Background: This study examined the mediating function of body weight perception (BWP) in the relation between body mass index (BMI) and unhealthy weight control behaviors (UWCBs; eg, fasting, using diet pills, or laxatives), and between BMI and suicidal ideation. It also explored the correlation between exposure to multiple UWCBs and suicidal…

Research suggests that substantial pre-service student teaching is essential for the preparation and retention of special educators. Using logistic regression analysis, survey responses of beginning special educators were analyzed to answer the following questions: Are beginning special educators more likely to leave the field if they have had…

This study linked nonlinear profile analysis (NPA) of dichotomous responses with an existing family of item response theory models and generalized latent variable models (GLVM). The NPA method offers several benefits over previous internal profile analysis methods: (a) NPA is estimated with maximum likelihood in a GLVM framework rather than…

Elitism argues that the values and experiences of the political elite shape policy, while institutionalism contends that an individual's behaviour is constrained by institutional settings. This article shows that both perspectives work well overall, while offering persuasive arguments, but the former is dominated by the latter. This explains the…

Over the past several years practitioners in the field of Criminal Justice have begun to reaffirm, recognize, and implement the tenets of the rehabilitative ideal within their daily operations. However, despite scholarly research showing that offender rehabilitation can have marked positive affects upon recidivism, many practitioners remain…

The purpose of the present study was to test a Self-Determination Theory (SDT) process model in relation to involvement in physical activity and competitive performance among students (N = 190). In this model, perceived autonomy support from teachers and coaches was expected to be positively related to autonomous motivation, perceived competence,…

School bullying has negative implications for adolescent academic competence, making it important to explore what factors promote such competence for adolescents who bully and who are bullied. Potential contextual and individual variables linked to academic competence were examined in the context of bullying. Data were derived from the Grades 5…

The purpose of this study was to investigate whether cognitive function in midlife predicts incident coronary heart disease (CHD), followed up over 6 years. Data on 5292 (28% women, mean age 55) individuals free from CHD at baseline were drawn from the British Whitehall II study. We used Cox regression to model the association between cognition…

We suggest that an over-arching "fitness factor" (an index of general genetic quality that predicts survival and reproductive success) partially explains the observed associations between health outcomes and intelligence. As a proof of concept, we tested this idea in a sample of 3654 US Vietnam veterans aged 31-49 who completed five cognitive…

Background: School environments may promote or hinder physical activity in young people. The purpose of this research was to examine relationships between school recreational environments and adolescent physical activity. Methods: Using multilevel logistic regression, data from 7638 grade 6 to 10 students from 154 schools who participated in the…

Relatively little is known about the incidence of declassification among young children who receive preschool special education services or about factors associated with declassification. The Pre-Elementary Education Longitudinal Study (PEELS) follows a nationally representative sample of children who were receiving preschool special education…

Objective: Little empirical research has examined the impact that child maltreatment may have on victims' long-term socioeconomic well-being. The current study sought to address this gap by exploring the relationship between childhood experiences of abuse and neglect and several indicators of socioeconomic well-being in adulthood. Method: Data…

Objectives: (1) Document the prevalence of childhood sexual abuse (CSA), childhood physical assault, psychological, physical and sexual intimate partner violence (IPV) in a nationally representative sample. (2) Assess the predictive value of CSA and other characteristics of the respondents and their current partners as potential risk factors for…

Background: This study examined the effects of a universal stress management program (Learn Young, Learn Fair) on stress, coping, anxiety and depression in fifth and sixth grade children. Methods: Fifty-two schools (1467 children) participated in a clustered randomized controlled trial. Data was collected in the fall of 2002, the spring of 2003,…

The research findings presented in this paper illustrate how the "value added" of schooling can be assessed empirically using cross-sectional data. Application of the regression-discontinuity approach within a multilevel framework produces both an estimate of the absolute effect of 1 year schooling and an estimate of the variation across…
