Mobile phones and other wireless devices that produce electromagnetic fields (EMF) and pulsed radiofrequency radiation (RFR) are widely documented to cause potentially harmful health impacts that can be detrimental to young people. New epigenetic studies are profiled in this review to account for some neurodevelopmental and neurobehavioral changes…

Parental involvement in education remains important for facilitating positive youth development. This study conceptualized parental involvement as a multidimensional construct--including school-based involvement, home-based involvement, and academic socialization--and examined the effects of different types of parental involvement in 10th grade on…

Studies on children of immigrants have generally ignored distinct developmental trajectories during adolescence and their role in the transition to adulthood. This study identifies distinct trajectories in cognitive, sociobehavioral, and psychological domains and estimates their consequences for young adults. Drawing data from a nationally…

Relations between nonrelative child care (birth to 4 1/2 years) and functioning at age 15 were examined (N = 1,364). Both quality and quantity of child care were linked to adolescent functioning. Effects were similar in size as those observed at younger ages. Higher quality care predicted higher cognitive-academic achievement at age 15, with…

Developmental, gender, and academic domain differences in causal attributions and the influence of attributions on classroom engagement were explored longitudinally in 115 African American adolescents. In Grades 8 and 11, adolescents reported attributions for success and failure in math, English and writing, and science. In Grade 11, English and…

Examined the relation between authoritative parenting and school achievement in 120 adolescents of 10-16 years. Adolescents who described their parents as treating them warmly, democratically, and firmly were more likely than their peers to develop positive attitudes toward their achievement and do well in school. (RJC)

This study treated a key relationship in the developmental ecology of adolescence, friendships, as multidimensional and context specific. First, it examined 4 characteristics of friends (academic achievement, alcohol use, emotional distress, and extracurricular participation) as independent factors and as components in holistic friendship group…

Examined effects of work intensity on 1,000 employed adolescents. Found that students who worked at higher intensity engaged in more alcohol use. Negative effects on mental health, academic achievement, and 2 other indicators of behavioral adjustment were not found, but seniors working at moderate intensity (fewer than 20 hours per week) had…

Studied relationship between adolescents' sleep/wake habits and daytime functioning. Found that self-reported total sleep times decreased from age 13 to 19 years. Struggling or failing students obtained less sleep, went to bed later, and had greater weekend delays of sleep than those with better grades. Students with inadequate sleep reported…

Examined the relationship between students' stress and social support in junior high school and the same students' psychological distress and school performance two years later. Stress and support variables predicted subsequent psychological distress. Stresses, but not supports, predicted subsequent school performance. (BC)

Compared adopted and nonadopted adolescents across variety of measures. Found that adopted adolescents were at higher risk in all domains examined, including school achievement and problems, psychological well-being, and physical health. Effect sizes for group differences were larger for males, younger or older adolescents, Hispanics or Asians,…

Examined whether differentiating processes existed for 7 composite indices of positive and negative adolescent adjustment in 720 sibling pairs. Found that siblings born 1 year apart at Time 1 were more similar to each other than were siblings born 2 years apart, suggesting that shared environmental influences counteract sibling differentiation…

Of 4,100 adolescents, those who characterized their parents as authoritative scored highest on psychosocial competence and lowest on behavioral dysfunction. The reverse was true for neglected adolescents. Adolescents from authoritarian homes scored high on obedience but low on self-perception. Adolescents from indulgent homes evidenced…

A sample of 183 third through sixth grade students were administered the Revised Class Play (RCP). Seven years later, these children and their parents completed a questionnaire measuring the students' behavioral symptoms and social, athletic, and academic competence. The RCP scores were related to adolescent competence and psychopathology. (BC)
