Us, them and we: How national and human identifications influence adolescents' ethnic prejudice.

Although there have been numerous studies on the relations between group identification and ethnic prejudice, it is less clear whether their associations reflect stable individual tendencies or rather situational or temporal fluctuations. This longitudinal multilevel study aimed to fill this gap by examining the between- and within-person associations of identification with the national and superordinate human groups and levels of prejudice against multiple ethnic minorities. A total of 883 Italian majority adolescents (Mage = 15.66, SD = 1.15 at T1, 49.7% females) completed questionnaires at four time points over the course of 1 year. Results showed that national identification was related to more prejudice at the between-person level but to decreases in prejudice at the within-person level. Additionally, human identification contributed to lower levels of and steeper decreases in prejudice at both the between- and within-person levels. Common and unique associations also emerged across different ethnic minority targets, but only for between-person effects. Overall, this study highlights the importance of distinguishing stable individual levels and momentary fluctuations of both ingroup identifications and ethnic prejudice in order to orient future interventions aimed at improving the quality of intergroup relationships.

Parents' and classmates' influences on adolescents' ethnic prejudice: A longitudinal multi-informant study.

The family and classroom are important contexts that can contribute to the socialization of ethnic prejudice. However, less is known about their unique, relative, and synergic contributions in influencing youth's affective and cognitive prejudice. The current longitudinal study examined these processes and possible moderators among 688 Italian youth (49.13% girls; Mage = 15.61 years), their parents (nmothers = 603, nfathers = 471; Mage = 49.51 years), and classmates between January/February 2022 and January/February 2023. Cross-lagged panel models highlighted that parents and classmates exert unique and relative influences on different dimensions of adolescents' prejudice. Additionally, different interaction effects also emerged for affective (i.e., adverse compensatory effect) and cognitive (i.e., amplifying effect) prejudice. Thus, adolescents draw from the multiple contexts of development to orient themselves in the social world.

A war on prejudice: The role of media salience in reducing ethnic prejudice.

INTRODUCTION: Ethnic prejudice poses a great challenge to the cohesion of current multicultural societies. Prior research has found that media portrayals of immigration-related issues might skew individual attitudes and feelings toward ethnic minorities. While these studies have focused on negative representations of ethnic minorities, less is known about the effects of media reports of unfortunate events affecting the victims of war, as in the case of the Ukrainian group in the Russia-Ukraine war. Therefore, the current research aims to examine whether media salience of this situation might change adolescents' ethnic prejudice against the Ukrainian minority. METHODS: A total of 1016 ethnic-majority Italian adolescents (Mage = 15.66, SDage = 1.17, 49.61% females) completed online questionnaires during school hours before (T1: January/February 2022) and after (T2: April/May 2022) the Russia-Ukraine war onset. Additionally, the media salience of the war was quantified separately for the national newspaper and Twitter. RESULTS: Levels of prejudice significantly decreased from T1 to T2 for multiple ethnic minority groups but especially so for the Ukrainian group. The results of bivariate Latent Change Score models highlighted that increased salience of the war in the national newspaper was significantly associated with decreased prejudice against Ukrainians, regardless of adolescents' levels of self-reported newspaper consumption. Conversely, changes in the salience of the war on Twitter were not associated with changes in prejudice. CONCLUSIONS: These findings highlight the importance of media attention for the war's victims in skewing individuals' outgroup perceptions and feelings.

Navigating Across Heritage and Destination Cultures: How Personal Identity and Social Identification Processes Relate to Domain-Specific Acculturation Orientations in Adolescence.

Personal identity and social identification processes can be challenging for adolescents belonging to an ethnic minority, who have to cope with the acculturation task of navigating several (and often conflictual) alternatives put forth by their cultural heritage community and destination society. Because identity and acculturation tasks are embedded in core domains of adolescents' life, this three-wave longitudinal study with ethnic minority adolescents (N = 244, 43.4% male; Mage = 14.9) examined how personal identity processes and social identifications are related to acculturation orientations in the education and friendship domains. Results of traditional cross-lagged models showed that, in the educational domain, adolescents who scored higher on cultural heritage maintenance compared to their peers, scored higher on commitment later on. In the friendship domain, stronger associations were found, such that adolescents who scored higher on cultural heritage maintenance compared to their peers, reported higher commitment and in-depth exploration later on, while those who scored higher on identification with friends reported over time also higher cultural heritage maintenance and destination culture adoption. Random-intercept crossed-lagged models indicated that, when adolescents reported above their own average on reconsideration of educational commitment, they reported increased cultural heritage maintenance later on. Furthermore, consistent associations (at baseline and over time) emerged. Overall, this study points to virtuous alliances between the fulfillment of tasks related to adolescents' identity development and acculturation.

Identity Matters for Well-Being: The Longitudinal Associations Between Identity Processes and Well-Being in Adolescents with Different Cultural Backgrounds.

Adolescents' identity processes and their levels of well-being are likely to be intertwined. On the one hand, how adolescents cope with the core developmental task of forming their identity has important implications for their well-being. On the other hand, experiencing a condition of well-being can help adolescents consolidate their identity. This longitudinal study adopted a multidimensional and culturally sensitive perspective to unravel how identity processes (i.e., commitment, in-depth exploration, and reconsideration of commitment) in two domains (i.e., educational and interpersonal identity) were developmentally related to multiple indicators of positive well-being (i.e., physical health, subjective, psychological, and social well-being) in adolescents with different cultural backgrounds. Participants were 1396 adolescents (Mage = 15.73, SDage = 1.23, 49.93% females; 20.89% with a migrant background) who completed questionnaires at four-time points across one year. Results of cross-lagged models confirmed the positive reciprocal associations between identity commitment and well-being in all its facets. The nuanced picture of associations of in-depth exploration and reconsideration of commitment with multiple dimensions of well-being highlighted the importance of adopting a multi-dimensional perspective on well-being and a domain-specific approach to identity. Multigroup analyses indicated that the associations between identity commitment in the educational domain and well-being are relevant, especially for adolescents with a migrant background. Overall, this study highlights the centrality of identity processes for adolescents' adaptation and points to a dynamic loop of reciprocal influences at the core of youth positive development.

A meta-analysis of longitudinal studies on the interplay between sleep, mental health, and positive well-being in adolescents.

Objective: This review aimed to summarize longitudinal research about the interplay between sleep, mental health, and positive well-being in adolescents. Method: Multiple search strategies were applied until 28th January 2023 to identify relevant research published in peer-reviewed journal articles or available grey literature. A final set of 63 studies were included in the systematic review and 42 in the meta-analysis. Results: Results highlighted that long sleep duration, good sleep quality, and low insomnia symptoms were bidirectionally related to lower internalizing (Sleep T1 â†’ Internalizing symptoms T2: r = -.20, p < .001; Internalizing symptoms T1 â†’ Sleep T2: r = -.21, p < .001) and externalizing (Sleep T1 â†’ Externalizing symptoms T2: r = -.15, p < .001; Externalizing symptoms T1→ Sleep T2: r = -.17, p < .001) symptoms, and to higher levels of psychological well-being (Sleep T1 â†’ Psychological well-being T2: r = .15, p < .001; Psychological well-being T1 â†’ Sleep T2: r = .15, p < .05). Moreover, good sleep was positively related to higher subjective well-being at a later time point (r = .18, p < .001). Conclusions: Overall, these findings suggest a bidirectional relation between different aspects of sleep, mental health, and positive well-being.

Positive and negative intergroup contact in school and out-of-school contexts: A longitudinal approach to spillover effects.

This study aims to tackle positive and negative intergroup contact in school and out-of-school contexts to test whether a spillover effect (i.e., the extent to which experiences that individuals have in one context spill over into another) applies to intergroup contact. Participants were 984 adolescents (Mage = 14.66; 62.7% female; 24.8% ethnic minority). Results indicated that positive contact in school was related over time to higher positive contact in out-of-school contexts and vice versa (i.e., valence consistent spillover effect). Positive contact in school was linked over time to lower negative contact in out-of-school contexts (i.e., valence inconsistent spillover effect). Overall, this study provides novel insights into the transmission of adolescents' intergroup contact across socialization contexts by emphasizing the leading role of positive contact in schools.

A near-mint view toward integration: Are adolescents more inclusive than adults?

The increasing ethnic and cultural diversity of contemporary societies has raised the importance of integration policies for people with a migrant background. Tools like the Migrant Integration Policy Index have been developed to evaluate different countries' integration approaches. If, on the one hand, focusing on what governments are doing to promote integration is necessary, on the other hand, it is of utmost importance to consider individuals' attitudes toward these policies. Study 1: A pilot study with 356 adolescents (41.1% female, 58.9% male; Mage = 15.38) and 200 adults (69% female, 31% male; Mage = 47.43) was conducted to test the psychometric proprieties of the Attitudes Toward Migrant Integration Policies scale. Study 2: A total of 1,156 adolescents (51.6% female, 48.4% male; Mage = 15.69), 1,288 parents (56.9% mothers, 43.1% fathers; Mage = 49.39), and 284 teachers (68.3% female, 31.7% male; Mage = 45.55) were involved in a study to evaluate how attitudes toward integration policies differ within generations (e.g., ethnic majority and minority groups), within families (e.g., adolescents vs. their fathers), and across generational groups (i.e., adolescents, parents, and teachers). Latent mean comparisons indicated that attitudes toward integration policies varied significantly across sex (for adolescents and parents), ethnic background (parents only), and school track (adolescents) groups. Regarding differences within family dyads, adolescents reported more positive attitudes toward integration policies than their fathers and mothers. Finally, teachers showed more positive attitudes compared to adolescents and their parents. Overall, this study highlights nuanced intergenerational differences, with adolescents standing in between the different positions of their parents and teachers.

Adolescents' Identity Development Predicts the Transition and the Adjustment to Tertiary Education or Work.

Although identity development is crucial in individuals' psychological adjustment from adolescence to adulthood, little is known about its impact in the transition to tertiary education or work. This study examined whether identity development during high school predicts career choices and adjustment (i.e., engagement) and maladjustment (i.e., burnout) after graduation. A total of 357 Japanese adolescents participated throughout the 3-year period of vocational high school (Mage = 15.75; 62.75% girls). A follow-up assessment, at 18 months after the school-to-tertiary education or school-to-work transitions, was conducted. Higher identity synthesis during high school years predicted entry into tertiary education, while higher identity confusion predicted transition to work. Furthermore, higher identity synthesis during the high school years predicted higher post-graduation academic engagement, and higher levels of identity confusion predicted higher levels of post-graduation academic or work burnout. Overall, this study contributes to the understanding of the role of identity development in adolescence as a valuable asset for predicting the transition and the adjustment to tertiary education or work.

The Longitudinal Interplay between Sleep, Anthropometric Indices, Eating Behaviors, and Nutritional Aspects: A Systematic Review and Meta-Analysis.

Sleep is fundamental for adolescents' healthy development but undergoes dramatic changes in quantity and quality due to the conflict between biological and social rhythms. Insufficient sleep has been associated with worse physical health status and irregular eating behaviors in adolescents. This review aims to systematically synthesize the longitudinal associations between adolescents' sleep dimensions (i.e., duration, timing, quality, and insomnia symptoms) and physical health indicators (i.e., anthropometric indices, fat percentage, and risk of obesity), eating behaviors, and nutritional aspects (i.e., type of diet related to the intake of specific foods and nutrients, amount and timing of food consumption, energy expenditure). A total of 28 longitudinal studies were included. The meta-analytic results showed that longer sleep duration, better sleep quality, and lower insomnia symptoms were associated with lower BMI and fat percentage and that shorter sleep duration (<7 h) and lower sleep quality were associated with a higher risk of obesity. Conversely, anthropometric indices were not related to sleep over time. Limited literature examined the bidirectional association between adolescents' sleep and their eating behaviors and nutritional aspects. Such knowledge sheds new light on the role of sleep for adolescents' health, highlighting the need to examine further the interplay between these variables.

External validity of the reduced Morningness-Eveningness Questionnaire for Children and Adolescents: an actigraphic study.

The aim of this study was to examine the external validity of the reduced Morningness-Eveningness Questionnaires for Children and Adolescents, using circadian motor activity, assessed through actigraphy, as an external criterion. Overall, 458 participants (269 females), with a mean (standard deviation) age of 15.75 (1.16) years, took part in this study. Each adolescent was requested to wear the actigraph Micro Motionlogger Watch actigraph (Ambulatory Monitoring, Inc., Ardlsey, NY, USA) around the non-dominant wrist for 1 week. At the end of the actigraphic recording, participants completed the reduced Morningness-Eveningness Questionnaires for Children and Adolescents. We extracted the motor activity counts, minute-by-minute over the 24 h, to depict the 24-h motor activity pattern, and we adopted the statistical framework of functional linear modelling to examine its changes according to chronotype. According to the reduced Morningness-Eveningness Questionnaires for Children and Adolescents cut-off scores, 13.97% of participants (n = 64) belonged to the evening-types category, 9.39% (n = 43) to morning-types, while the remaining (76.64%, n = 351) to the intermediate-types category. Evening types moved significantly more than the intermediate and morning types from around 10:00 p.m. to 2:00 a.m., while the opposite pattern of results was observed around 4:00 a.m. The results highlighted a significant difference in the 24-h motor activity pattern between chronotypes, in line with the expectations based on their well-known behaviour. Therefore, this study shows that the external validity of the reduced Morningness-Eveningness Questionnaire for Children and Adolescents, established by considering motor activity (recorded through actigraphy) as an external criterion, is satisfactory.

Sleep Is a Family Affair: A Systematic Review and Meta-Analysis of Longitudinal Studies on the Interplay between Adolescents' Sleep and Family Factors.

Family is one of the primary socialization contexts influencing adolescents' psychological health. In this regard, a crucial indicator of adolescents' health is their sleep quality. Nevertheless, it is still unclear how multiple family factors (i.e., demographic and relational) are intertwined with adolescents' sleep quality. For this reason, this systematic review with meta-analysis aims to comprehensively summarize and integrate previous longitudinal research investigating the reciprocal relation between demographics (e.g., family structure) and positive (e.g., family support) and negative (e.g., family chaos) relational family factors and adolescents' sleep quality. Several search strategies were applied, and a final set of 23 longitudinal studies that matched the eligibility criteria were included in this review. The total number of participants was 38,010, with an average age at baseline of 14.7 years (SD = 1.6, range: 11-18 years). On the one hand, the meta-analytic results showed that demographic factors (e.g., low socio-economic status) were not related to adolescents' sleep quality at a later time point. On the other hand, positive and negative family relational factors were positively and negatively related to adolescents' sleep, respectively. Furthermore, the results suggested that this association could be bidirectional. Practical implications and suggestions for future research are discussed.

Sleep Well, Study Well: A Systematic Review of Longitudinal Studies on the Interplay between Sleep and School Experience in Adolescence.

Adolescents spend most of their daily time in school and performing school-related activities. Different aspects of their school experiences, such as school performance, psychological factors related to school, and structural factors, consistently impact adolescents' health and are likely to be intertwined with their sleep (i.e., quantity and quality, sleep disturbances). This systematic review aimed to comprehensively summarize the reciprocal and longitudinal associations between adolescents' sleep and multiple aspects of their school experience. Using multiple search strategies and applying a two-step selection process, 25 journal articles matched the eligibility criteria and were thus included in the review. The results highlighted the contribution of poor sleep quality and sleep disturbances in predicting longitudinal school experiences-related outcomes (i.e., decreasing school engagement and performance, and increasing school-related burnout, absenteeism, and bullying). At the same time, the results showed how experiences related to the school's psychological factors (e.g., high levels of school burnout and stressful environment) and structural characteristics (e.g., early school entrance time) affect youth sleep over time (i.e., decreasing sleep quality and quantity). These main findings provided novel insights into the bidirectional relationship between school experience and sleep health, highlighting the importance of more longitudinal research investigating all aspects of healthy sleep, including the size and direction of the association.

I was, I am, I will be: Identity and time perspective before and during COVID-19.

The ways in which youth reach a stable identity, a core developmental task of emerging adulthood, are intertwined with their perceptions of the past, present, and future. Additionally, these dynamics are embedded in and are strongly influenced by the socio-historical context and concurrent events, such as COVID-19. This study examines how different groups of emerging adults (university students and workers) engage in identity processes in educational/vocational and interpersonal domains and frame their perspective of time before (N = 299, Mage  = 21.90; 51.4% females) and during the pandemic (N = 497; Mage  = 23.11; 68.2% females). Significant differences in identity processes and time perspective emerged between the two cohorts. Moreover, significant associations between identity and time perspective were found to be similar across different identity domains and cohorts.

The Association between Sleep Patterns, Educational Identity, and School Performance in Adolescents.

Adolescents' school experience can be developmentally related to adolescents' sleep. This study aimed to understand how sleep patterns (i.e., sleep duration and sleep-schedule) and weekend sleep-recovery strategies (i.e., social jetlag and weekend catch-up sleep) are associated with adolescents' school experience (i.e., educational identity and school performance). Moreover, the differences in the school experiences between adolescents with different numbers of weekend-sleep-recovery strategies were assessed. For this purpose, 542 Italian adolescents (55.2% females, mean age 15.6 years) wore an actigraph for one week. After the actigraphic assessment, questionnaires on educational identity and school performance were administered. Results showed that short sleep-duration, later bedtime during weekdays and weekends, and a higher amount of social jetlag were negatively associated with school performance. Furthermore, adolescents who did not use any sleep-recovery strategy during the weekend presented lower levels of educational in-depth exploration compared to adolescents with higher levels of catch-up sleep but not social jetlag. These data pointed out a potentially detrimental role of social jetlag on school performance and differences in identity processes between adolescents who used and those who did not use sleep-recovery strategies, which could affect adolescents' psychosocial adjustment.

The Social Side of Sleep: A Systematic Review of the Longitudinal Associations between Peer Relationships and Sleep Quality.

In adolescence, peer relationships become crucial since youths start to rely on their peers for support. Thus, multiple facets of adolescents' well-being are affected by their peer relationships. In this vein, one of the central well-being aspects that could be affected by the peer relationships of adolescents is sleep quality. Nevertheless, it is still unclear how multiple peer relationship factors (i.e., positive, negative, emotional, and behavioral issues related to peer relationships) are intertwined with adolescents' sleep quality. For this reason, this systematic review with meta-analysis aims to summarize longitudinal studies to uncover how the interplay between peer relationship factors and adolescents' sleep quality unfolds over time. Nineteen longitudinal studies involving a total of 21,232 adolescents were included. Overall, findings from this review showed that (a) positive peer relationships and sleep quality were not associated over time; (b) negative peer relationships and sleep quality were bidirectionally associated over time; (c) few studies evaluated the bidirectional relations between emotional and behavioral issues and sleep quality, showing links with sleep schedule and duration, but not with sleep quality. Meta-analytic results were discussed, considering their implications.

Determinants of workers' well-being during the COVID-19 outbreak: An exploratory study.

Inspired by the Conservation of Resource theory (Hobfoll, 1989), this study investigated the role of a broad set of personal vulnerabilities, social, and work-related stressors and resources as predictors of workers' well-being during the COVID-19 outbreak. Participants were 594 workers in Italy. Results showed that personality predispostions, such as positivity, neuroticism and conscientiousness as well as key aspects of the individuals' relationship with their work (such as job insecurity, type of employment contract or trust in the organization) emerged as factors promoting (or hampering) workers' adjustment during the COVID -19 outbreak. Interactions between stressors and resources were also found and discussed. Supplementary Information: The online version contains supplementary material available at 10.1007/s12144-021-02408-w.

The complex story of educational identity in adolescence: Longitudinal relations with academic achievement and perfectionism.

OBJECTIVE: Education has a strong impact on adolescent development. This study investigated the complex longitudinal associations between educational identity processes, academic achievement, and perfectionism. METHOD: The study used a 4-wave design (N = 744 adolescents, Mage = 15.2 years, 55% girls). RESULTS: Results showed that self-oriented perfectionism mediated the longitudinal relation between academic achievement and educational commitment, whereas educational commitment mediated the longitudinal relation between self-oriented perfectionism and academic achievement. Also, a unidirectional positive direct link from educational in-depth exploration to socially prescribed perfectionism was found, while self-oriented perfectionism mediated the positive relationship between academic achievement and exploration. Finally, higher academic achievement led to decreases in educational reconsideration of commitment, whereas socially prescribed perfectionism predicted increases in educational reconsideration of commitment and decreases in academic achievement. CONCLUSIONS: These findings bring forward the intricate and possibly sabotaging links between educational identity processes, academic achievement, and perfectionism.

Meeting in school: Cultural diversity approaches of teachers and intergroup contact among ethnic minority and majority adolescents.

This study investigated the associations between cultural diversity approaches endorsed by teachers and adolescents' positive and negative intergroup contact in schools. Participants were 984 adolescents (Mage  = 14.66; 62.7% female; 24.8% ethnic minority) involved in a three-wave longitudinal study between 2019 and 2020. Results highlighted that perceived equal treatment by teachers was related to higher positive and lower negative contact over time. However, perceived support for contact and cooperation and interest of teachers in children's cultural background were not related to either positive or negative contact over time. Importantly, the results were replicated across ethnic minority and majority adolescents. This study provides novel insights into the key role that teachers can play in promoting cultural diversity approaches to facilitate harmonious intergroup interactions in schools.

The future is present in the past: A meta-analysis on the longitudinal associations of parent-adolescent relationships with peer and romantic relationships.

Positive peer and romantic relationships are crucial for adolescents' positive adjustment and relationships with parents lay the foundation for these relationships. This longitudinal meta-analysis examined how parent-adolescent relationships continue into later peer and romantic relationships. Included longitudinal studies (k = 54 involving peer relationships, k = 38 involving romantic relationships) contained demographically diverse samples from predominantly Western cultural contexts. Multilevel meta-regressions indicated that supportive and negative parent-adolescent relationships were associated with supportive and negative future peer and romantic relationships. Meta-analytic structural equation modeling (k = 54) indicated that supportive parent-adolescent relationships unidirectionally predicted supportive and negative peer relationships, while negative parent-adolescent relationships were bidirectionally associated with supportive and negative peer relationships. Maintaining mutually supportive relationships with parents may help adolescents to develop positive social relationships.
