Reservation-dwelling American Indian adolescents are at exceedingly high risk for cannabis use. Prevention initiatives to delay the onset and escalation of use are needed. The risk and promotive factors approach to substance use prevention is a well-established framework for identifying the timing and targets for prevention initiatives. This study…

Children with autism spectrum disorder experience bullying more frequently than their typical peers. Inconsistent definitions for and imprecise measurement of bullying in the literature impede a better understanding of this difference, and multiple types of bullying topographies create additional dimensions for analysis. In this study,…

Purpose: To develop models to estimate aerobic fitness (VO[subscript 2]max) from PACER performance in 10- to 18-year-old youth, with and without body mass index (BMI) as a predictor. Method: Youth (N = 280) completed the PACER and a maximal treadmill test to assess VO[subscript 2]max. Validation and cross-validation groups were randomly formed to…

Purpose: The purpose of this study was to test the convergent validity of Omron 306 using Biospace InBody 720. Method: A total of 267 participants (145 boys; aged 10.4-17.9 years) completed testing during a single session. Each measure provided percent body fat (%BF), while the InBody 720 included fat-free mass (FFM). The validity was examined…

Latent class analysis was used to examine the career preparation of 5,227 11th-grade Korean adolescents taken from the Korean Education Longitudinal Study of 2005 (KELS:2005). Three career preparedness groups were identified, to reflecting Skorikov's ("J Vocat Behav" 70:8-24, 2007) conceptualization of career preparedness: prepared,…

Very few studies have investigated predictors of change in various gross motor outcomes in ambulatory children with cerebral palsy (CP). The aim of this study was to identify potential predictors for change in gross motor outcomes measured during various tasks in children with CP. A group of 45 children (age, 6-15 years) with CP and 7 potential…

A longitudinal sample from the Educational Longitudinal Study of 2002 was used to determine differences in work outcomes between (a) individuals with learning disabilities or emotional-behavior disorders and (b) individuals with or without disabilities. Twelve factors were arranged into individual, family, school-peer, and community categories.…

Latent class analysis (LCA) is a statistical method used to identify subtypes of related cases using a set of categorical or continuous observed variables. Traditional LCA assumes that observations are independent. However, multilevel data structures are common in social and behavioral research and alternative strategies are needed. In this…

Chronic victimisation in adolescence is a traumatic experience with potential negative long-term health consequences. Given that victimisation has been shown to increase over the transition from primary to secondary school, longitudinal data from 1810 students transitioning from primary to secondary school were used to identify victimisation…

Ten cerebral palsied adolescents and young adults with complex communicative needs who use augmentative and alternative communication were studied. They were classified according to their high versus low working memory capacity and according to their high versus low phonological skills into two groups of participants. These groups were compared on…

From a large school-based sample (N = 3,084), 49 Mainland Chinese adolescents (31 girls, 18 boys) who endorsed all DSM-IV criteria for bulimia nervosa (BN) or sub-threshold BN and 49 matched controls (31 girls, 18 boys) completed measures of demographics and sociocultural experiences related to body image. Compared to less symptomatic peers, those…

This prospective study of 17 high-functioning residentially treated adolescents with autism found that cognitive shifting, as measured by card sorting tests, was the only significant factor in predicting progress in social understanding. (Author/JDD)

Presents a factor analysis of personality, intellectual, demographic and behavioral variables obtained from 200 incarcerated delinquents. Results described five personality groupings: White and older adolescent offenders with good verbal skills, the older adolescent offender, the institutional disrupter, and the anxious, verbal offender rated as…

A dual taxonomy is presented to reconcile two incongruous facts about antisocial behavior, that it shows impressive continuity over age, but its prevalence changes dramatically over age, increasing almost tenfold during adolescence. Studying delinquents earlier in life may yield more information about the causes and antecedents of antisocial…

Studied patterns of boys' social development by examining data from two longitudinal studies: a Finnish study of eight year olds begun in 1968; and a French Canadian study of six year olds begun in 1984. Patterns were identified using variables of aggression, hyperactivity, inattentiveness, anxiety, and lack of prosocial behavior. (LB)
