This meta-analysis examined main effects and heterogeneity in associations between popularity and academic adjustment in the U.S. and China across 41 studies. The aggregated sample included 22,151 children and adolescents (10,934 boys; 11,217 girls) from both countries, with U.S. students from various ethnic backgrounds. Results in the U.S. were…

This study examined trajectories of repetitive sensorimotor (RSM), insistence on sameness (IS), and verbal RRBs from ages 2-19 in a well-characterized longitudinal cohort. We also tested the factor structure of the ADI-R restricted and repetitive behavior (RRB) domain at age 19 and the inclusion of a verbal RRBs factor, in addition to previously…

Purpose: The study objective was to determine if the validated Behavioral Inflexibility Scale (BIS) is sensitive to the detection of developmental changes in inflexibility in a sample of autistic children. Methods: Parents of autistic children (n = 146, 3-17 years) completed the BIS at two time points, one year apart, to examine change. Results:…

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…

The objective of this study is to determine whether the parent-child relationship exerts a mediating effect on the influencing relationship of the self-concept of children and adolescents with career maturity. To this end, we processed data from 5621 students who participated in the first through fifth rounds of the survey in the 2013 Korea…

Understanding how learning changes during human development has been one of the long-standing objectives of developmental science. Recently, advances in computational biology have demonstrated that humans display a bias when learning to navigate novel environments through rewards and punishments: they learn more from outcomes that confirm their…

Research and data on youth and delinquency is critical for identifying opportunities and developing strategies to support positive development through prevention and intervention. Responses to youth misbehavior by youth-serving systems -- including education, child welfare, behavioral health, and justice systems -- can play an important role in…

Purpose: Research of mindfulness-based programming/interventions (MBP) for youth has proliferated in recent years; however, heterogeneity of MBP for youth impede determination of optimal programmatic structure across developmental periods. Design/Approach/Methods: Expert MBP scientists and instructors were iteratively surveyed using the Delphi…

The period between adolescence to young adulthood can be stressful for parents of transition-aged children (14 to 22 years old) with autism spectrum disorder. A systematic review was undertaken to examine if existing interventions address the unique parental stressors of this phase and if the scales used to measure parental stress and anxiety are…

This research focused on the transactions between the social competence of the child, positive maternal parenting, and the maternal perception of the father's support for the mother from early childhood to adolescence. Specifically, whether the transactions between these domains are consistent or limited to certain developmental periods and…

Four longitudinal models are used to present a short review of research into adolescent psychosocial development. This review reveals adolescent development to proceed in a regular manner. This process of regular development suggests that it might be possible to uncover rules of intra-individual development. The aim of this paper is to propose a…

Incarceration in the United States affects not only the individuals incarcerated, but also the whole family system, including children. 1.5 million children younger than 18 have had parents incarcerated at some point in their life (U.S. Census Bureau, 2021), and children have been called the hidden victims of the mass incarceration that is…

The debate about the impact of digital media use on youths' well-being is polarized. We provide a comprehensive examination of the relationship between digital media use and adolescents' affective well-being, investigating both within-person and between-person associations. We also examined how age and gender moderate these relationships,…

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.…

Knowledge is needed about specific supports and barriers for successful transitions to adulthood for autistic youth, especially from the perspective of parents, who are highly involved in transition preparation. We conducted a qualitative thematic analysis of previously conducted semi-structured interviews with 39 parents of 41 autistic…
