Creativity and entrepreneurship are fundamental to the personal and professional development of new generations and for social progress in general. The primary aim of this study was to analyze changes in the creative and entrepreneurial self-efficacy of undergraduates as they progress through university, and to examine whether these trajectories…

Processes that unfold over individuals' life courses are often associated with inequalities later in life. The literature lacks methodological approaches to analyze inequalities in outcomes between groups, for example, between women and men, in a life-course-sensitive manner. We propose a combination of methods--of sequence analysis, which enables…

Using data from the Early Childhood Longitudinal Study--Kindergarten Class of 2011 (n = 14,370; 51% Male; 51% White; 14% Black; 25% Hispanic; 4% Asian; and 6% Other), this study examined the cumulative, timing-specific, and enduring associations between student-teacher relationships in the United States and a broad range of student outcomes.…

Introduction: Recent evidence demonstrates an association between social media addiction (SMA) and aggressive behaviors; however, the longitudinal relationship between these two variables remains not fully understood. The aim of this study was to examine the longitudinal relationship between SMA and aggressive behaviors (overt and relational…

Background: The home learning environment (HLE), along with center-based early childhood education (ECE) programs, plays an essential role in promoting early childhood development (ECD). HLE can become more or less stimulating over time due to caregivers' tendency to adapt HLE in response to preschoolers' evolving developmental status, of which…

Introduction: Children from multicultural families in South Korea are at high risk of bullying victimization, highlighting the need for a deeper understanding of the challenges they face. This study explores the gendered dynamics of depressive symptoms associated with persistent exposure to bullying victimization among these youths, as well as the…

This article investigates whether experiences of the PhD trajectory during the first year of enrolment predict dropout during a later stage. More specifically, we studied how supervisor support, time pressure and passion for research relate to dropout among PhD students and assessed the role of discipline in this process. We used longitudinal data…

In recent years, bullying victimization has received increasing attention from researchers worldwide. The link between bullying victimization and reactive aggression is well-established in numerous studies. However, longitudinal association and underlying mechanisms remain less explored. This study examined gender-specific effects of traditional…

Introduction: Individuals' math value beliefs are theorized to influence who persists in STEM. However, the existing findings on gender differences in adolescents' math value beliefs are inconsistent. The goal of this study was to use three existing datasets to help clarify when gender differences emerge for high school adolescents and for whom…

Motor, psycho-emotional, cognitive and social variables, plus other factors like gender, influence how schoolchildren perceive their motor competence level. By means of a hierarchical linear regression analysis, this longitudinal study aimed to determine the predictive value that coordination, anxiety, and self-esteem at the age of 9 years can…

This study examines how self-esteem and social support (parental, teacher, and peer) influence the career maturity of Korean adolescents over time. By synthesizing findings from 18 longitudinal studies, a meta-analysis was conducted. Results reveal that while self-esteem initially shows a strong correlation with career maturity, this relationship…

Background: Negative outcomes of peer dislike may be especially severe in early adolescence, when peers play a crucial role in individual adjustment. However, it remains unclear whether peer dislike predicts later emotional and motivational aspects of school adjustment, and if the negative outcomes are more pronounced in certain gender contexts.…

This study aimed to introduce an ego-resiliency questionnaire for preadolescents (the ER-P) by restructuring the ER89 using the data of 1398 preadolescents from the Panel Study on Korean Children. The ER-P was proposed as a 10-item second-order instrument with two factors (Optimal Regulation and Openness to Life Experiences). The ER-P achieved…

The detection of differential item functioning (DIF) is important in psychological and behavioral sciences. Standard DIF detection methods perform an item-by-item test iteratively, often assuming that all items except the one under investigation are DIF-free. This article proposes a Bayesian adaptive Lasso method to detect DIF in graded response…

Research suggests that heterogeneous life experiences (e.g. multilingualism) might facilitate the development of mental flexibility. The current paper presents the conceptual replication of a study originally presented by Greve and colleagues [Greve, W., Koch, M., Rasche, V., and Kersten, K. (2021). Extending the Scope of the 'Cognitive Advantage'…
