The System for Observing Fitness Instruction Time (SOFIT) is a direct observation system specifically developed for use during physical education (PE; McKenzie, 1991; McKenzie, Sallis, & Nader, 1991). The purpose of this study was to validate the estimates of time spent in various physical activity intensities obtained with the paper and pencil…

Despite the conceptual importance of impression motivation in predicting social anxiety (Leary & Kowalski, 1995; Schlenker & Leary, 1982), no research has tested the link between impression motivation specifically regarding one's physical appearance (appearance impression motivation, or AIM) and social physique anxiety (SPA). The purpose of this…

The factor structure, psychometric properties, and relationship with personality variables of a Spanish version of the Savings Inventory-Revised (SI-R) are investigated in a sample of 381 undergraduate students. A maximum likelihood factor analysis suggests a three-factor structure, which is similar but not identical to that of the original…

This article explores the relationship between student engagement and student self-assessment. It reports on research that has reconceptualised ways of understanding levels of student engagement among primary school learners who live in poor communities. These ways of understanding have been influential in the development of a student…

Children's internalizing problems are a concerning mental health issue, due to significant prevalence and continuity over time. This study tested a multivariate model predicting young children's internalizing behaviors from parenting practices, parents' anxiety-depression and family stressors. A community sample of 2 year old children (N=112) was…

The purpose of this study was to explore the interrelationship of social and adaptive skills in adults with bipolar disorder and severe or profound intellectual disability. A bipolar group (N=14), a severe psychopathology group without bipolar disorder (N=14), and a control group with no DSM-IV Axis I diagnosis (N=14) were compared on the…

Addressing a gap in process-oriented understanding of relations between marital conflict and children's adjustment, propositions of the emotional security hypothesis from a family-wide perspective were tested in a longitudinal research design. Participants were 181 families and their 11-12 year-old-child (115 boys, 76 girls) living in Wales, in…

Exercise has an important role to play in the prevention of child and adolescent obesity. Recent school-based interventions have struggled to achieve meaningful and lasting changes to exercise levels. Theorists have suggested that this may, in part, be due to the failure to incorporate psychosocial mediators as they relate to behaviour change.…

A behaviorally-uninhibited temperament, callous-unemotional (CU) features, and harsh parenting have been associated with specific patterns of aggressive behavior in older children and adolescents. We tested the additive and interactive effects of these factors in predicting different types of aggressive behavior in a high-risk preschool sample.…

Background: The present study was designed to investigate the association between visual exploratory behaviour in early infancy, novelty seeking in adolescence, and the dopamine D4 receptor (DRD4) genotype. Methods: Visual attention was measured in 232 three-month-old infants (114 males, 118 females) from a prospective longitudinal study using a…

Background: The goal of this study was to investigate the stability and correlates of adolescent suicidal risk across adolescence. Methods: Suicidal risk was studied longitudinally in N = 593 subjects in 1994, 1997, and 2001 at mean ages of 13, 16, and 20 years. Three partly overlapping suicidal risk groups were compared to three control groups…

Background: Most studies of the effects of trauma on mental health have generally not separately assessed psychosocial functioning, and in those that have key issues have received little attention, such as the relation between the time courses of the two kinds of outcome, and detailed assessment of social functioning in a range of domains. The…

Background: Previous empirical studies of the cognitive sequelae of failure to thrive in infancy have led to apparently inconsistent conclusions. Methods: Studies of cognitive abilities in failure to thrive were located through published bibliographies, supplemented by a search through MEDLINE. They were classified (a) into those in which the…

This study compared the peer functioning of a community sample of preschool boys with pervasive hyperactivity (N=33) and comparison boys (N=34), and examined the extent to which any differences in peer functioning between these groups could be explained by comorbid child conduct problems and parenting factors. The quality of boys' peer relations…

The current study is framed within an ongoing effort of probing students' attitudes and expectations about knowing and learning physics, which has driven several investigations during the past decade. The questionnaire we developed focuses on physics students' views regarding a variety of specific learning activities, which are presented by title…
