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…

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…

Adolescence is a period of heightened emotionality. If the adolescents cannot perceive, understand, regulate and function with their emotions it will leave indelible marks on their behaviour and personality. During adolescence (age 12 to 18 yrs), the transition from childhood to adulthood is most important. Children are becoming more independent,…

Cultural background can influence cognition, including executive functions (EFs), abilities that encompass skills responsible for self-regulation of thoughts and behavior. The seminal unity and diversity model of EFs proposes the existence, in adulthood, of at least three correlated but separable EF latent (shared variance in more than one…

This mixed method study explored whether and how familial mentor support may have influenced the parent-adolescent relationship, and whether the impact of familial mentor support on the parent-adolescent relationship may have differed across adolescents' developmental stage. Findings from analyses of survey data from 106 Black adolescents…

Solitude occurs from childhood to old age. In this special issue introduction, we offer a lifespan perspective on matters of solitude with the aim to point to pertinent issues in the field. We propose that solitude serves important functions that may vary across different times in life and that solitude needs to be considered in the context in…

We used latent growth curve analysis to extend research on associations between early puberty and adverse peer relations by examining the role of pubertal timing in the developmental trajectories of peer victimization and offending from early- to mid-adolescence. We made use of three-wave longitudinal data collected annually from a cohort of…

Throughout childhood and adolescence, humans experience marked changes in cortical structure and cognitive ability. Cortical thickness and surface area, in particular, have been associated with cognitive ability. Here we ask the question: What are the time-related associations between cognitive changes and cortical structure maturation.…

This prospective study examined the developmental changes over time of adolescents diagnosed in toddlerhood with autism spectrum disorder and searched for child characteristics at toddlerhood that predict outcome at adolescence. The study included 65 participants who were divided into low cognitive (developmental quotient [less than] 85; N = 41)…

Adolescence is a time of transition characterized by rapid physical, neurological, cognitive, and socioemotional development. As students move toward adulthood, their bodies and minds change. Those changes affect how they learn and, likewise, should influence how educators interact with youth. This Alliance for Excellent Education report…

Puberty is often implicated in the onset or exacerbation of psychopathology during adolescence, and pubertal timing and tempo have emerged as important predictors of wellbeing. In the psychosocial literature there is a tendency to view individual differences in the nature (timing and tempo) of pubertal development as either determined by stress…

The current study focused on the relationship between body dissatisfaction and depressive symptoms on the threshold of adolescence. We aimed to investigate the role of body dissatisfaction in gender differences in depressive symptoms, as well as the impact of social support from peers and parents. Mediation and moderation analyses were based on…

Sentiment analysis is a computational method that automatically analyzes the valence of massive quantities of text. Basic sentiment analysis involves extracting and counting emotionally-laden keywords from passages of text (e.g., "hate," "love," "happy," "sad"). This study describes using sentiment analysis…

The stability of callous-unemotional (CU) traits and both individual and contextual factors that influence this stability have been studied in community adolescent samples but not to great extent in adolescents who have been arrested. We estimated the developmental changes in CU traits measured over the course of 36 months (6-month intervals)…

Manifestations of internalizing problems, such as specific symptoms of anxiety and depression, can change across development, even if individuals show strong continuity in rank-order levels of internalizing problems. This illustrates the concept of heterotypic continuity, and raises the question of whether common measures might be construct-valid…
