The aim of this study was to examine what kind of school performance and behaviour profiles could be identified among students in the final grade of basic education in the Swedish speaking parts of Finland (N = 1149, grade 9), how these differed in temperament and how temperament could explain profile differences in first language (L1, Swedish)…

Information Literacy education is challenged by an ever-changing and complex environment. The design and development of current and effective Information Literacy education requires a thorough understanding of how young people search information online, which mainly happens with generalist search engines. The present study involved a voluntary…

Camouflaging includes strategies used by individuals to mask or hide autistic traits. Research has shown that both autistic and neurotypical individuals engage in camouflaging and that there may be sex differences in the reasons for camouflaging in autistic adults. The purpose of this qualitative study was to extend previous research on the lived…

Adolescent risk-taking behaviors, encompassing both positive and negative dimensions, play a pivotal role in shaping psychosocial adaptation. As prior research has predominantly adopted variable-centered approaches, the heterogeneity patterns of risk-taking behaviors and their differential associations with multidimensional adaptation remain…

Phones have become pervasive in many teenagers' lives, and outdoor educators are increasingly faced with making decisions regarding technology. This case study sheds light on the complex relationship between teenagers, phones and residential outdoor environmental education by exploring the experiences of participants at a phone-free summer camp in…
