The variety of worldview profiles among Finnish upper secondary school students
In recent decades, the religious landscape in Europe, including Finland, has witnessed increasing secularisation and pluralisation. In this article, we investigate the diversity of worldviews among Finnish upper secondary school students from a person-centred perspective. By conducting latent class analysis on the survey responses of 973 students, we distinguish five different worldview profiles: the Culturally Moderate are characterised by avera…
A Whole‐Population Comparative Study of the School Experience and Its Association With Depressive Symptoms Among Immigrant‐Origin and Native Preadolescents
In European studies, immigrant‐origin adolescents report more mental health symptoms than natives do. The school is an important developmental context for them, and more research is needed about how their school experience is related to their mental health symptoms, and whether these relations vary by group. The aim of this study was to assess the prevalence of depressive symptoms, and their association with the school experience among native and…

Profiles of climate change distress and climate denialism during adolescence
This study investigates adolescents’ climate change distress and climate denialism profiles with two cohorts (born in 2008 and 2006) using longitudinal data from two waves collected in 2020 and 2021 ( N = 3,002). In addition, the explanatory similarity of the subgroups regarding general well-being and pro-environmental behavior was studied. Four profiles were identified. The largest group was named the normative-carefree group because they had lo…
Sense of belongingness, discrimination, and mental health
A sense of belonging is crucial for mental health and well-being, but immigrants may find achieving a sense of belonging elusive. This study examined the relationship between sense of belonging and mental health among Finnish native, and first- and second-generation immigrant adolescents (N = 61 540) in Finland. Moreover, we estimated whether sense of belonging buffered the negative effect of experienced discrimination on mental health. Immigrant…

This study, utilising data from six EU countries ( N = 6221; M age = 14.5; SD = 1.4), takes a person-oriented approach to examine adolescents digital skill profiles and associations with socioeconomic, digital activity, and socioemotional antecedents. Using late…
Study Burnout and Engagement During Covid-19 Among University Students
The COVID-19 pandemic forced most universities to switch from in-person to remote teaching from May 2020 to May 2021. This period covered three semesters of studies, and due to these changes students experienced fundamental changes in their learning. The present research was carried out 3 times during the pandemic (e.g., May 2020, December 2020, and April 2021) to investigate study engagement and burnout, and their associations with various deman…
Intraindividual associations between active social media use, exhaustion, and bedtime vary according to age—A longitudinal study across adolescence
INTRODUCTION: The majority of adolescents engage with others online, and using social media is one of their top activities. However, there is little longitudinal evidence addressing whether active social media use is associated with study-related emotional exhaustion or delayed bedtime at the individual level of development during adolescence. METHOD: A 6-year longitudinal survey study (N = 426, female, 65.7%) was conducted (2014-2019) in Finland…
Value Profiles Among Finnish Adolescents and Their Associations With Subjective and Social Well-Being
Previous research on Schwartz’s theory of basic human values has mostly applied a variable-oriented approach . This study took a person-oriented approach and investigated how values co-occur and are manifested in individuals, that is, what kind of value profiles exist and how they differ in terms of subjective (i.e., life satisfaction) and social well-being (i.e., sense of belonging). In a sample of Finnish adolescents ( N = 973; women 59.6%; M a…
Anxiety and depression symptoms and their association with discrimination and a lack of social support among first- and second-generation immigrant adolescents
The focus in the present study is on how experienced discrimination, being able to discuss personal matters with parents, and having someone to discuss personal worries with relate to symptoms of depression and generalized anxiety among first- and second-generation immigrant-background adolescents (aged 14–15) living in Finland. The data used was collected for the National School Health Promotion Study (2017) conducted by The Finnish Institute fo…

Longitudinal Trajectories, Social and Individual Antecedents, and Outcomes of Problematic Internet Use Among Late Adolescents
Given the detrimental effects associated with problematic internet use (PIU) and the need to better understand its nature and evolution, the present study examined the development of PIU in a sample of 1,750 adolescents (aged 16–19) from Finland over a 3-year period. We documented the social (loneliness, perceived maternal and paternal behaviors) and individual (sex) antecedents, as well as the outcome implications (depressive symptoms, substance…
A Two-wave Longitudinal Study of Identity Profiles Based on Eight Dimensions
It has been suggested that dual-cycle models of identity formation do not fit well with Erikson’s identity theory and the identity status paradigm due to 1) contradictory statuses, 2) problems with discerning past exploration and 3) ambiguity or limitations of the life domains covered. The present study extended the Dimensions for Identity Development Scale (DIDS) with three additional dimensions suggested previously, examined identity profiles a…
