Background: Growing evidence indicates a link between unintentional injury and both disruptive and emotional psychopathology. We present further evidence of these associations and address the underlying mechanisms. We also examine the genetic contribution to unintentional injury. Methods: The Virginia Twin Study of Adolescent Behavioral…

The aim of the present study was to investigate the differential relationships between five dimensions of motivational climate and achievement goals, as the latter have been conceptualized by the revised achievement goal theory. Adolescents (N = 336, M age = 13.45 years, SD = 1.04) participating in a summer camp in southern Greece took part in the…

In the present study, the authors examined the relations among parenting styles, parental practices, sympathy, and prosocial behaviors in adolescents. The participants were 233 adolescents (M age = 16.7 years; 69% girls; mostly White) from public high schools in the Midwestern region of the United States who completed measures of prosocial…

Our study examined variations in adolescent adjustment as a function of maternal and paternal parenting styles. Participants included 272 students in grades 9 and 11 from a public high school in a metropolitan area of the Northeastern US. Participants completed measures of maternal and paternal parenting styles and indices of psychological…

The purpose of this study was to use a validated instrument to determine the attitudes and knowledge of high school teachers regarding food irradiation, and to determine the correlations among their knowledge and attitudes and certain demographic variables. Knowledge and attitudes about food irradiation were measured in selected high school family…

This study examined the strength of tracking sport participation from childhood to early adulthood among the Dunedin Multidisciplinary Health and Development Study cohort. Participation in sport, dance, or gymnastics as part of a club or group (outside of school) was assessed at ages 7, 9, 15, 18, and 21 years. In addition to the traditionally…

This study examined the effects of classroom in degree for ability (the degree to which peer nominations as academically capable show high consensus and focus on a relatively few number of children in a classroom) on first grade children's peer acceptance, teacher-rated classroom engagement, and self-perceived cognitive competence. Participants…

The purpose of this study was to understand the relationship of student entry data to current English language learning status. District-level data was obtained for 1,942 K-5 native Spanish-speaking elementary-level students administered the oral Spanish and English Language Assessment Scale (Pre-LAS). Canonical correlation analysis was used to…

This study investigated how predictive the Cross Racial Identity Scale (CRIS; B. J. Vandiver, W. E. Cross, F. C. Worrell, & P. Fhagen-Smith, 2002), a measure of Black racial identity, was of African American cultural practices, beliefs, and attitudes (i.e., enculturation) as measured by the African American Acculturation Scale-33 (H. Landrine & E.…

This study evaluated the viability of using a self-report instrument to assess separately the positive form and negative form of perfectionism among 317 Chinese gifted students in Hong Kong.

We used the Early Childhood Longitudinal Study--Kindergarten Cohort (ECLS-K) data to examine how important mathematics readiness levels are to subsequent achievement growth and the efficacy of instruction and engagement in producing such growth. The ECLS-K selected a nationally representative sample of kindergartners in fall 1998 and is following…

We examined the predictive utility of narcissism among a community sample of children and adolescents (N=98) longitudinally. Analyses focused on the differential utility between maladaptive and adaptive narcissism for predicting later delinquency. Maladaptive narcissism significantly predicted self-reported delinquency at one-, two-, and…
