The field of developmental psychopathology has made significant contributions to our understanding of both typical and atypical development. However, while there are established theories for developmental psychopathology with detailed criteria for pathological outcomes, there is less agreement regarding development under optimal conditions and the definition of positive outcomes. In this conceptual paper, I make the case that a better understanding of positive child development is crucial because it will not only advance our general knowledge on human development but also complement current work on developmental psychopathology. After defining positive development as the development of positive functioning in children, such as skills, strengths, competencies, and wellbeing, rather than the absence of problems, current concepts with relevance for positive development are reviewed, before highlighting gaps in our knowledge on positive development and suggestions for future research. Although several of the reviewed frameworks provide important contributions to the conceptualization of positive development, most of them focus on positive functioning in adults with limited consideration of development in the early years. More research is needed that specifically targets the development of positive outcomes from early childhood onward in order to develop a more comprehensive and holistic theory of positive child development.

Attention-deficit/hyperactivity disorder (ADHD) symptoms are associated with myriad adverse outcomes, including interpersonal difficulties, but factors that moderate the developmental course and functional impact of ADHD over time are not well understood. The present study evaluated developmental contributions of the triarchic neurobehavioral traits (boldness, meanness, and disinhibition) to ADHD symptomatology and its subdimensions from adolescence to young adulthood. Participants were twins and triplets assessed at ages 14, 17, and 19 (initial N = 1,185, 51.2% female). Path analyses using negative binomial regression revealed that boldness at age 14 was associated with more ADHD symptoms cross-sectionally (especially hyperactivity/impulsivity), but fewer symptoms (especially inattention) at age 19 in the prospective analysis. Notably, inclusion of interpersonal problems at ages 14 and 17 as covariates reduced the latter effect to nonsignificant. Disinhibition concurrently and prospectively predicted higher levels of ADHD symptoms, including both subdimensions, and the prospective effects were partially mediated by greater social impairment at age 17. Meanness prospectively (but not concurrently) predicted higher levels of hyperactivity/impulsivity symptoms. Sex moderated certain associations of meanness and disinhibition with ADHD symptoms. These findings highlight how fundamental neurobehavioral traits shape both psychopathology and adaptive outcomes in the developmental course of ADHD.

There is a recognition about the mental health, educational, and career-related benefits of positive youth development (PYD) in children and youth. This brief review provides an overview of the current application of PYD in school settings. We begin by summarising the common conceptualisations of PYD along with similar and distinct features in such models. Then, we discuss the current status of PYD research and highlight the academic and psychological payoffs of PYD-oriented programs in schools. Importantly, this review elaborates future directions and practical implications for PYD researchers and practitioners in school contexts.

Participation in sport during high school has been linked with a range of educational and developmental benefits. However, there is limited research investigating the benefits of participation in sport from the perspective of Aboriginal former youth sports participants. The purpose of the current research was to investigate how participation in sports impacted on the educational engagement, aspirations and development of Aboriginal former youth sports participants. Interpretive phenomenological analysis of semistructured interviews with six participants was conducted. Analysis was conducted utilising the Positive Youth Development asset framework. Participants reported a positive influence for their participation in youth sport on key education related assets including, achievement motivation, school engagement and relationships with teachers. Participants also reflected upon the role of participation in youth sports in the development of empowerment and positive identity assets. For these participants, involvement in youth sport had clear educational and developmental benefits. It is concluded that youth sports participation is one developmental context with the potential to have a positive influence on the educational and developmental trajectory of Aboriginal youth.
