The differential susceptibility model proposes that some children are more susceptible to both positive and negative peer relationships than others. However, experimental evidence supporting such a proposition is relatively scarce. The current experiment aimed to help address this gap, investigating whether Chinese (pre)adolescents who have higher…

Research has indicated that early sexual intercourse in high school is associated with poor health outcomes such as unintentional pregnancy and sexually transmitted infections (STIs). What is lacking in the research is an understanding of the relationship between even earlier sexual initiation (i.e., before the age of 13) and alcohol, tobacco, and…

Early alcohol use places youth at risk for adverse health, academic, and legal consequences. We examined the content of the total array of self-cognitions in urban youth to determine whether specific self-concept profiles were associated with early drinking, drinking-related self-cognitions, and conduct problems. We conducted a secondary analysis…

The goal of this study was to assess longitudinal, predictive relationships between community violent crime and reactive and proactive aggression. Community violent crime data were gathered from local law enforcement agencies and combined with an existing dataset of at-risk youth. Aggression was assessed by parents using the Reactive and Proactive…

The risk of delinquent to antisocial behaviors among youth (teenagers) seem to be more prevalent in group homes than other foster homes. The aim of this study was to examine the association between negative peer influence and youth antisocial behaviors in group homes. Participants were 875 youth aged 10 to 17 at baseline (2010-2011). Logistic…

Youth with Autism Spectrum Disorder (ASD) are at an increased risk for developing obesity when compared to their typically developing peers. Given higher prevalence of obesity in youth with ASD, understanding factors relating to success in obesity treatment provides insight into implementing efficacious treatments for youth. The current study…

Youth with or at-risk for emotional and behavioral disorders (EBD) within residential treatment facilities have a variety of needs (e.g., academic, behavioral, social-emotional). A concerted effort is required to address these areas of need so that youth can develop their skills to be successful within their present and future settings. In chapter…

Maternal depression has consistently demonstrated reliability as a predictor of major depression in children. However, the effect of gender as a potential moderator remains under-researched. This study examined gender differences in depression and hypothesized that maternal depression would be more greatly associated with depression in girls by…

Background: Children with mild intellectual disabilities and emotional and behavioural problems whose parents have mental health concerns are at an increased risk of developing problems themselves. This study analysed the effectiveness of the 'You are Okay'-program aimed to support these children and parents and to reduce the risk of problem…

The thrifty phenotype and fetal overnutrition hypotheses are two developmental hypotheses that originated from the "developmental origins of health and disease" (DOHaD) perspective. The DOHaD posits that exposures experienced prenatally and early in life may influence health outcomes through altering form and function of internal organs…

Intellectual disability (ID) is a neurodevelopmental disorder characterized by cognitive delays. Inborn errors of metabolism constitute an important subgroup of ID for which various treatments options are available. We aimed to identify potential biomarkers of inherited metabolic disorders from the children with ID using tandem mass spectrometry…

The goal of this study was to test nonverbal intelligence and neighborhood social capital as protective factors against future delinquency in early adolescent youth placed at risk by virtue of their involvement in childhood conduct problems. Analyzing longitudinal data from 3,028 youth (1,565 boys, 1,463 girls) in one cohort of the Longitudinal…

Adolescence is a time of exceptional physical health juxtaposed against significant psychosocial and weight-related problems. The study included 241, 10-to-13-year-old youth with autism spectrum disorder (ASD, N = 138) or typical development (TD, N = 103). Standardized exams measured pubertal development, height (HT), weight (WT), heart rate (HR),…

Bullying occurs in all countries where it has been studied, causing negative effects on victims such as anxiety, low self-esteem and even depressive pictures that hinder their integration into the school environment. In Spain, one of the first studies to address peer abuse as violent behaviour in the school context was that of the Ombudsman in…

Purpose: The primary aim of this study was to investigate the extent to which individuals with facial and/or speech differences secondary to a craniofacial anomaly experienced bullying through social media platforms during late school age and adolescence. Method: Using an online survey platform, a questionnaire was distributed via several public…
