Background: In recent times, sibling bullying has emerged of interest to researchers concerned with the emotional and behavioural implications for victimization regardless of type and setting. Aims: This research attempts to extend current knowledge on both peer and sibling bullying and to determine the effects of poly-setting victimization. This…

We investigated the effects of seeing the instructor's (i.e., the model's) face in video modeling examples on students' attention and their learning outcomes. Research with university students suggested that the model's face attracts students' attention away from what the model is doing, but this did not hamper learning. We aimed to investigate…

This study examined the role of family obligations and school adjustment in explaining immigrant adolescents' adaptation. Despite a relatively low socio-economic status, immigrant adolescents have been found to have a pattern of adaptation superior to that of national adolescents. Immigrant adolescents' strong sense of family obligations and…

Objective: To assess the prevalence and frequency of medical marijuana diversion and use among adolescents in substance abuse treatment and to identify factors related to their medical marijuana use. Method: This study calculated the prevalence and frequency of diverted medical marijuana use among adolescents (n = 164), ages 14-18 years (mean age…

Objective: To use confirmatory factor analysis to test the construct validity of the proposed "DSM-5" symptom model of autism spectrum disorder (ASD), in comparison to alternative models, including that described in "DSM-IV-TR." Method: Participants were 708 verbal children and young persons (mean age, 9.5 years) with mild to severe autistic…

Background: Research to date suggests that as many as 12-15% of young people engage in self-harm behaviour; however, the current understanding of the psychological basis of adolescent self-harm is limited. The objective was to determine whether adolescents who self-harm are a psychologically homogenous group. It was hypothesised that psychological…

The theory of planned behavior identifies important proximal determinants of behavior, including attitude toward the behavior, perception of subjective norms exerted by significant others, and perception of perceived control over performance of the behavior. Because research in the planned behavior tradition has focused on desirable target…

In order to recognize behavioral patterns in children and adolescents at risk for developing bipolar disorder, this study examined Child Behavior Checklist (CBCL) profiles of bipolar offspring both with (BD group) and without ("at-risk" or AR group) bipolar disorder themselves. The BD youth had three CBCL subscale T scores greater than…

The purpose of the present research is to compare early adolescents beliefs about parental and friend jurisdiction over relational aggression to their beliefs about parental and friend jurisdiction over physical aggression and personal behaviors. One hundred three adolescents (X age = 12 years, 11 months; SD = 12.46 months) are individually…

Research has revealed a considerable degree of stability of Type A behavior from adolescence to adulthood. Other research has reported an association between anger and certain dimensions of cardiovascular risk in adolescent subjects. Such findings suggest that further study of the Type A phenomenon as it is expressed in adolescents may enhance…

Delinquent (N=50) and nondelinquent (N=50) members of peer groups were rated by group workers in relation to their rule-violating behavior in group activities. Found delinquents violated rules more often, reacted more aggressively to rule violations of others, and denied their responsibility for rule violations more often. (Author)

Studied the individual and social connections between teenage and adult sexual outcomes over time, by race and locale, and by individual liaison using data from 28 counties in California. Results show that teenagers display behaviors virtually identical to those of adults of the same backgrounds and socioeconomic status. Implications for…

Many adolescents experiment with marijuana; the National Institute on Drug Abuse estimates that 46% of high school seniors have tried this drug at some time. Pushing boundaries is what young people do, and some researchers believe that trying marijuana is a normal part of growing up. RAND Corporation researchers have revisited Shedler and Block's…

A study sought to determine whether female innovative teens have mass media behavior similar to that of adult innovators. Research indicates that adult innovators (adult who are the first to adopt new ideas and products and who comprise 16% of the population) are more ventursome, better educated, more socially integrated, and have greater contact…

Compares an adolescent and a parental group with regard to standardized measures of alcohol consumption in order to test the hypothesis that drinking patterns are not unique to the adolescent society but rather exemplify the models in the adult community. Independent samples of students and adults were found to be very similar in patterns of…
