  • Parent‐adolescent relationships, Covid‐19‐related concerns, and life satisfaction among adolescents from diverse ethnic and socioeconomic backgrounds during school closures

    Open Access•Jessie Hillekens, Gülseli Baysu et al.•ARTICLE•Journal of Research on Adolescence•2026

    Amidst the abrupt school closure due to the COVID‐19 pandemic, adolescents faced unexpected challenges. Drawing on data collected 1 week before, during, and 1 year after the first COVID‐19 school closure in Belgium, this study investigated (1) changes in life satisfaction, (2) whether parent–child relationship quality served as a protective factor during school closures over and beyond COVID‐19‐related concerns; and (3) differences among early ad…

  • To Be Bicultural Is to Be Friends? Associating Early Adolescents' Cultural Identities and Behaviors With Friendship Networks in Minority‐Only Schools

    Open Access•Jessie Hillekens, T H Stark et al.•ARTICLE•Journal of Community Psychology•2026•Cited by: 2•References: 59

    Many ethnic minoritized adolescents attend minority‐only schools with no ethnic majoritized classmates, but we know little about their acculturation and friendships in such settings. This study examined how early adolescents' heritage and mainstream cultural identities and behaviors associated with friendship ties in minority‐only class networks. Early adolescents ( N = 146, M age = 11.24, 54.4% boys) in minority‐only primary schools reported the…

  • Adolescent self‐construal across cultures

    Open Access•Veljko Jovanović, Sabirah Adam et al.•ARTICLE•Journal of Research on Adolescence•2025•Cited by: 3•References: 12

    Despite the critical role of culture in understanding adolescent self and identity, there is a lack of cross-culturally validated measures of adolescent self-construal. The present study evaluated cross-national measurement invariance of the Aspects of Identity Questionnaire-IV (AIQ-IV), assessing four dimensions of self-construal: personal, relational, public, and collective. The sample included 16,795 adolescents aged 14-19 years from 30 countr…

  • Trajectories of cross-ethnic friendships and their associations with school adjustment in ethnic minority adolescents

    Gülseli Baysu, Jessie Hillekens et al.•ARTICLE•Developmental Psychology•2025•Cited by: 1

    Cross-ethnic peer relations are pivotal for ethnic minority adolescents. However, there is limited understanding of how their cross-ethnic friendships with majority peers in school develop over time. Addressing this, this study aimed to investigate individual trajectories of cross-ethnic friendship in school and how they predict long-term school adjustment. Our sample consisted of 1,445 Turkish- and Moroccan-heritage minority adolescents in 70 Be…

  • Positive and Negative Emotional Experiences in Adolescents across 32 Countries

    Open Access•Veljko Jovanović, Sabirah Adam et al.•ARTICLE•Applied Research in Quality of Life•2025•References: 75

  • Trajectories of ethnic discrimination and school adjustment of ethnically minoritized adolescents

    Open Access•Gülseli Baysu, Eva Grew et al.•ARTICLE•Child Development•2024

    This study investigated trajectories of ethnic discrimination experiences in school, diversity climates as contextual antecedents, and school adjustment as outcome. Latent-Growth-Mixture-Models of repeated self-reported discrimination over 3 years (2012–2015) by 1445 ethnically-minoritized adolescents of Turkish and Moroccan background in 70 Belgian schools (52.6% boys, M age = 15.07) revealed four trajectories: low (72.5%), moderate (16.6%), ini…

  • Family Functioning, Identity Commitments, and School Value among Ethnic Minority and Ethnic Majority Adolescents

    Open Access•Stefanos Mastrotheodoro, Jessie Hillekens et al.•ARTICLE•Journal of Youth and Adolescence•2024•References: 73

    Ethnic minority youth show worse school adjustment than their ethnic majority peers. Yet, it remains unclear whether this gap can be explained by differences in family functioning and consequent identity commitments. This study examined (1) whether family functioning relates to identity commitments over time and (2) whether identity commitments impact later school value (3) among minority and majority adolescents. Minority ( N = 205, M age = 16.2…

  • Multiple pathways of integration

    Open Access•Jessie Hillekens, Gülseli Baysu et al.•ARTICLE•Child Development•2023

    Tracing developmental pathways of immigrant-origin adolescents, this 3-year longitudinal study (2012–2015) examined within-person changes in cultural orientations and their consequences for school adjustment. Multivariate latent growth mixture modeling confirmed multiple pathways of integration, revealing variable acculturative changes along dual trajectories of heritage and mainstream orientations among European-origin (N = 592, M age = 14.45, 5…

  • How School and Home Contexts Impact the School Adjustment of Adolescents from Different Ethnic and SES Backgrounds During Covid-19 School Closures

    Open Access•Jessie Hillekens, Gülseli Baysu et al.•ARTICLE•Journal of Youth and Adolescence•2023•Cited by: 1•References: 44

    Many schools worldwide closed to contain the spread of the COVID-19 virus. However, the consequences of school closures for the school adjustment of adolescents from different ethnic and SES backgrounds remain unclear. This study examined how school adjustment changed before, during, and after school closure across adolescents from different ethnic and SES backgrounds; and which factors in home and school contexts served as resources. Early adole…

  • How Diversity Approaches Affect Ethnic Minority and Majority Adolescents

    Open Access•Gülseli Baysu, Jessie Hillekens et al.•ARTICLE•Child Development•2021

    This study aimed to relate school diversity approaches to continuity and change in teacher–student relationships, comparing Belgian-majority (N = 1,875, Mage = 14.56) and Turkish and Moroccan-minority adolescents (N = 1,445, Mage = 15.07). Latent-Growth-Mixture-Models of student-reported teacher support and rejection over 3 years revealed three trajectories per group: normative-positive (high support, low rejection) and decreasing-negative (moder…

  • Parent‐early adolescent relationship quality and problem behavior in Hungary, the Netherlands, India, and Iceland

    Open Access•Jessie Hillekens, Kirsten L Buist et al.•ARTICLE•Scandinavian Journal of Psychology•2020

    Higher parent‐child relationship quality has been associated with less internalizing and externalizing problem behavior. However, it remained less clear whether these associations are universal or depend on the country under investigation. Furthermore, fathers are still understudied, even though there is increasing evidence of their important role in early adolescent development. Our study compared the association of mother‐child as well as fathe…
