The socialisation of adolescent boys and girls takes place primarily online in virtual environments, where cyberbullying is one of the greatest current social dangers faced by that age group. Socio-emotional e-competencies (i.e., competencies that apply specifically to online environments) are a protective factor against cyberaggression and…

Purpose: Repetitive negative thinking (RNT) is the process of engaging in negatively valenced and habitual thought patterns. RNT is strongly associated with mental health conditions and often affects quality of life. This study explored RNT in older school-age children and adolescents who stutter to quantify the relationship between RNT and…

Children with complex behavioral profiles (e.g., ASD + ADHD) may experience delays in obtaining a final diagnosis. Low-resource or underrepresented groups may be at even greater risk for delayed diagnosis. We assessed the effect of sociodemographic factors, symptom complexity and co-occurring conditions, and identifier of first symptoms on…

The aim of this research is to examine associations of adolescent sexting with gender, being in a romantic relationship, and other online or offline sexual behaviors, using the adolescent sexting scale A-SextS as a standardized measure. Data were collected from a sample of 579 Spanish secondary school pupils (47.3% girls), between the ages of 11…

Developmental science suggests that the consequences of mental health problems for life-course outcomes may depend on the timing of their onset. This study investigated the extent to which mental health predicted educational attainment at ages 17, 20, and 25 and whether gender moderated the links between mental health and educational attainment.…

We investigated performance levels on conducting continuous two-footed jumping of preschool children (4 years old) to high school students (16 years old) to clarify the developmental progression and sex differences in motor coordination and agility. In total, 450 children (boys: 227; girls: 223) participated in this study. We set 10 obstacles to…

The current study examined the Five Cs model of positive youth development (PYD; Lerner et al., 2005) in U.S. Mexican-origin youth (N = 674, 50% female) and tested the extent to which ethnic pride, familismo, and respeto, as an index of cultural orientation, predicted PYD across midadolescence. PYD was modeled using a bifactor structure, which…

Criminal activity is seasonal, peaking in the summer and declining through the winter. We provide the first evidence that arrests of children and reported crimes involving children follow a different pattern: peaking during the school year and declining in the summer. We use a regression discontinuity design surrounding the exact start and end…

Connectives such as "because" and "but" are crucial for signaling coherence relations in discourse. They contribute to a better reading comprehension and, thus, academic performance. The aim of this article is to contribute to our understanding of connective development during teenage years by studying individual differences in…

Bullying bystanders' reactions are important for either stopping or perpetuating bullying behaviors. Given school-based bullying programs' focus on bystanders, understanding the associations between school-level factors and individual bystander responses can improve intervention efficacy. Data from 64,670 adolescents were used to examine bullying…

The purpose of the current study is to examine the relationship between polyvictimization, school social climate, and depression in adolescents. Authors also looked at whether school social climate acts as a moderator of the interaction between polyvictimization and depressive symptoms. Furthermore, to have a deeper analysis, they included--as…

The purpose of this study was to examine the factors associated with academic achievement in at-risk high school students attending one of four charter schools in south Florida geared toward dropout prevention. Several factors were identified through a thorough review of the literature to identify the common demographic variables associated with…

Although previous research has found trait emotional intelligence (TEI) to be a moderate predictor of bullying behaviors in adolescents, this work has limited generalizability. The current study is the first to use a multidimensional approach to both TEI and bullying behaviors when looking at their relationship in high school students. The study…

This study aimed to investigate the predictive roles of gender and self-efficacy (academic, social, and emotional) on the academic resilience of adolescents. Participants consisted of 346 adolescents (227 girls and 119 boys). Data were collected through the Academic Resilience Scale, the Self-efficacy Scale for Children, and a demographic…

This study aimed to explore the effects of mattering, social media addiction, online activity, school connectedness, age, and gender on anxiety/depressive symptomatology among U.S. adolescents. A nationally representative Qualtrics panel sample consisting of 441 adolescents (M[subscript age] = 17.3; SD[subscript age] = 1.67) participated in this…
