- Introduction: Sleep is a complex behavior affected by biological, psychosocial and contextual factors typically present during adolescent development (Becker, Langberg, & Byars, 2015), including increasing autonomy from parents, increasing school demands, and socializing more with peers. However, these normative changes do not explain temporary vs chronic sleep disturbances. Who are the adolescents at risk for developing chronic sleep problems? Some risk factors have been identified as crucial, such as poor sleep hygiene and family stressors, others are not as clear, such as technology use (Bartel et al., 2015). The impact of another important stressor for youths other than family, the school context, has received less attention (Meldrum, 2018). The aim of this study was twofold; first, we explored sleep trajectories from early to mid-adolescence to be able to identify a risk group showing persistent sleep problems (including insomnia and short sleep duration); then, we investigated the role of school stressors (i.e., conflicts with teachers, performance, school-leisure conflict, attendance), controlling for well-established risk factors, in the development of chronic sleep problems in a large cohort of adolescents.Materials and methods: We used three longitudinal waves of questionnaire data collected annually from a sample of Swedish adolescents (n = 1457; Mage = 13.2 [range: 12- 15 years], SD = .43; 52.7% boys). We collected the data from all schools in three communities in central Sweden, during school hours. Using established measures, the students reported on their sleep duration (calculated from reported bedtime, wake-time, and sleep onset latency; SSHS [Wolfson & Carskadon, 1998]), insomnia symptoms (ISI; Morin, 1993), sleep hygiene (ASHS; LeBourgeois, Giannotti, Cortesi, Wolfson, & Harsh, 2005), technology use, and perceived stress (including school, home and peer related stress) (ASQ; Byrne, Davenport, & Mazanov, 2007).First we used latent class analysis (LCA) to identify adolescents' sleep trajectories, then we used regression analyses to predict the risk-group trajectory of chronic insomnia and short sleep duration, controlling for gender.Results: We found four trajectories for adolescents' insomnia; 1) low-stable (69%), 2) low-increasing (18%), 3) high-decreasing (8%), 4) high-increasing (5%; 'risk-group'). For sleep duration, we found two trajectories; 1) ∼8 h slightly decreasing (79%), 2) ∼7 h decreasing (21%; 'risk-group').School stressors including stress of fitting in with peers, stress of schoolwork leaving too little leisure time, a stressful home environment, poor sleep hygiene, and being female were risk factors for chronic insomnia symptoms. Conflicts with teachers, poor sleep hygiene, and being female were risk-factors for chronic insufficient sleep.Conclusions: Over and above well-known risk-factors for poor sleep, such as poor sleep hygiene, (Bartel et al., 2015), school-related stress was a significant predictor of persistent sleep problems in adolescents. Therefore, helping adolescents to handle school stress might be a promising strategy to improve sleep health in this population.

- Study Objectives: We examined how adolescents’ sleep patterns (i.e. insomnia symptoms and sleep duration) change from early- to mid-adolescence and whether adolescents follow different trajectories. Furthermore, we also examined the characteristics of adolescents within different trajectories, with a specific focus on the role of school-related stress.Methods: We used three longitudinal waves of questionnaire data collected annually from a sample of Swedish adolescents (n = 1294; Mage = 13.2 [range: 12–15 years], SD = .42; 46.8% girls). Using established measures, the students reported on their sleep duration, insomnia symptoms, and perceived school-stress (including stress of school performance, peer and teacher relations, attendance, and school-leisure conflict). We used latent class growth analysis (LCGA) to identify adolescents’ sleep trajectories, and the BCH method to describe the characteristics of the adolescents in each trajectory.Results: We found four trajectories for adolescents’ insomnia symptoms; (1) low insomnia (69%), (2) low-increasing (17%, ‘emerging risk-group’), (3) high-decreasing (9%), (4) high-increasing (5%; ‘risk-group’). For sleep duration, we found two trajectories; (1) ~8 h sufficient-decreasing (85%), (2) ~7 h insufficient- decreasing (15%; ‘risk-group’). Adolescents in risk-trajectories were more likely to be girls and consistently reported higher levels of school stress, particularly regarding school performance and attending school.ConclusionsSchool stress was prominent among adolescents suffering from persistent sleep problems, especially insomnia, and deserves further attention.

- Research on ethnic victimization to date has done little to identify the reasons why adolescents victimize their peers due to their ethnic background. To address this limitation, we examined: (1) the extent to which prejudiced attitudes within adolescents' close and larger social networks determine their engagement in ethnic harassment, and (2) the extent to which classroom ethnic diversity plays a role in any such link. Our sample included 902 Swedish adolescents (M age = 14.40, SD = .95; 50.3% girls). We found that Swedish adolescents who held negative attitudes toward immigrants or who were surrounded by prejudiced peers were more likely to be involved in ethnic harassment, particularly in classrooms with high ethnic diversity. Adolescents in classrooms with a high anti-immigrant climate were more likely to harass their immigrant peers. These findings suggest that prejudiced beliefs in youth social networks put young people at risk of engaging in ethnic harassment, particularly in ethnically diverse classrooms.

- The study examined how adolescents' individual characteristics and class context are related to bystander behaviors in cases of ethnic victimization. The sample included 1065 adolescents in Sweden (M-age = 13.12, SD = 0.42; 55%males). Female adolescents, adolescents of immigrant background, and adolescents with positive attitudes toward immigrants had greater intentions to defend and comfort victimized peers. Positive inter-ethnic contact norms in class were positively associated with intention to comfort the victim. Teachers' non-tolerance of ethnic victimization was positively related to adolescents' intentions to ask the perpetrator to stop and talk to teacher. The effects were the same across adolescents with different attitudes toward immigrants. Findings highlight the importance of class context and teachers in fostering adolescents' prosocial and assertive interventions in bias-based hostile behaviors.

- Immigrant and minority youth are at risk of ethnic victimization. Despite an increasing number of studies that aim to understand the consequences of such negativity, relatively little attention has been paid to understanding who the perpetrators of ethnic victimization are. To address this gap in knowledge, the present study examined whether youth who victimize their peers due to their ethnic background are also those who engage in non-ethnicity-based victimization. The study also investigated the underlying factors, i.e., impulsivity, empathy, moral disengagement, and attitudes toward immigrants, that are common or specific to groups of youth. The sample included 949 adolescents residing in Sweden (Mage = 13.11, SD = 0.41; range: 12–15; 46% girls). Cluster analysis revealed four distinct groups of adolescents, based on their reports of ethnic and non-ethnicity-based victimization: (1) low on both forms of victimization, (2) high on ethnic victimization only, (3) high on non-ethnicity-based victimization only, and (4) high on both forms of victimization. The results showed that being morally disengaged is a common denominator of ethnic and non-ethnicity-based victimizers. Difficulties in regulating impulses and lack of perspective-taking skills trigger youth’s engagement in non-ethnicity-based victimization. Lack of empathic concerns and low levels of positive attitudes toward immigrants are the bases of ethnic victimization. Together, these findings suggest that the precursors of ethnic and non-ethnicity-based victimization have similarities as well as differences, which require further attention in developing programs aimed at preventing different forms of peer victimization.

Ethnic Harassment and Immigrant Youth's Engagement in Violent Behaviors : Understanding the Risk Factors

Tidskriftsartikel (refereegranskat)abstract
- The present study aimed to examine whether ethnic harassment was related to violent behaviors among immigrant youth over time and to identify the risk factors. The sample comprised immigrant adolescents living in Sweden (N = 365; Mage = 13.93, SD = 0.80). Results showed that the more youth were ethnically harassed, the more they engaged in violent acts over time. A separated identity significantly moderated the effect of ethnic harassment on youth's engagement in violent behaviors. Specifically, ethnic harassment positively predicted engagement in violent behaviors only at high levels of separated identity. Impulsivity and school ethnic composition did not act as moderators. The findings suggest that preventing violent behaviors among immigrant youth requires a focus on promoting positive interethnic relationships, and multicultural identity among immigrant youth.
