While interest pursuits are widely recognized as being inherently contextual, what this contextuality entails for different interests has not been explored systematically. In this study, 410 adolescents reported on the temporal, epistemic, material, geographical, social, institutional, and cultural dimensions of 820 interest pursuits. Latent class…

Social media addiction (SMA) is considered a risk factor for aggressive behaviors in adolescents, while its underlying mechanisms remains unclear. In this study, we investigated the possible mediating roles of nighttime social media use and sleep quality in the relationship between SMA and aggressive behaviors. A sample of 773 Italian secondary…

This study investigated the extent to which adolescent social network positions are associated with the risk of lifetime daily smoking and nicotine dependence (ND), and whether these associations differ by gender. Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 6,267), this study estimated multinomial logistic…

Many mothers do not communicate with their adolescent about sexual health topics due to perceived barriers. Our goal in this study was to shed light on the activities mothers engage in to prepare for sexual health discussions with their young adolescents. We also examined the extent to which mothers' past sexual communication behaviour and…

Interoception refers to the processing of internal bodily states and plays a critical role in motivational processes and behaviours. Instruments for assessing its subjective components (i.e., interoceptive sensibility) during childhood are crucially needed. Thus, in this study, we adapted and evaluated the psychometric properties of the…

This study aimed to develop and validate machine learning models to predict intensities in children and adolescents with cystic fibrosis (CF) across different accelerometry brands and placements. Thirty-five children and adolescents with CF (11.6 ± 2.8 yrs; 15 girls) and 28 healthy youth (12.2 ± 2.7 yrs; 16 girls) performed six activities whilst…

Background: Excessive worry during adolescence can significantly impact mental health. Understanding adolescent concerns may help inform mental health early intervention strategies. Objective: This study aimed to identify frequent concerns among Australian secondary school students, exploring individual and demographic differences. Whether…

Background: The research involved 170 adolescents from Brazil and Ecuador, ages 12 to 19, comprising 87 Brazilians and 83 Ecuadorians, with a gender distribution of 95 females and 75 males. Purpose: Examine the correlation between impulsivity, emotional symptoms, and the use of alcohol and drugs among teenagers in these countries. Methods:…

To address teenage learners' risk of HIV, STIs and pregnancy, good quality school-based sexuality education is of great importance. In this paper we address Zimbabwean young people's construction of sex and sexuality education. We draw from semi-structured individual interviews conducted with forty-seven teenage boys and girls aged between 15 and…

Writing is an essential skill that is critical for learning, communication and employment. Female advantages in writing test scores have been reported in several studies. The aims of this study were to systematically quantify sex differences in writing achievement as measured by individually administered achievement tests via multilevel…

Polysubstance use is associated with myriad short- and long-term health outcomes. Although prior research has documented differences in polysubstance use between lesbian, gay, bisexual, transgender, queer/questioning, and other sexual and gender minoritized (LGBTQ +) youth and their heterosexual/cisgender counterparts, as well as between subgroups…

The National Assessment of Educational Progress (NAEP) is an integral measure of academic progress across the nation and over time.

Background: Children and adolescents with language problems have poorer mental health compared with their non-language impaired peers. Less is known about mental health in adults with a history of language problems. This paper presents a systematic review and meta-analysis that addresses this gap in the literature. Specifically, it summarises the…

This study focuses on one type of excluding and isolating behaviour, the essence of which is the breakup of social interactions with a group member, which falls within the commonly accepted definition of ostracism. Based on interviews with 29 adolescents aged 12-18 (including 15 girls and 14 boys, all of whom were students in public schools…

The dynamics of mastering the degrees of freedom in motor learning are still far from being understood. The present work explored coordination dynamics in a redundant task, relating it to performance and adaptation in a serial stimulus tracking task. One hundred and sixty-three children (10-14 years of age) continuously responded to sequential…
