The aims of this study were (a) to analyze the prevalence of different types of self-harm on the internet and differences by sex and age, and (b) to examine the relationship of self-harm on the internet with intrapersonal factors (i.e., depression and anxiety) and interpersonal factors (i.e., family cohesion and social resources). Method: The sample consisted of 1,877 adolescents (946 girls) between 12 and 17 years old (Mage = 13.41, SD = 1.25) who completed self-report measures. Results: Approximately 11\% of the participants had been involved in some type of self-harm on the internet. The prevalence was significantly higher among girls than boys and among adolescents older than 15 years old. Depression and anxiety increased the risk of self-harm on the internet, whereas family cohesion decreased the probability of self-harm on the internet. Conclusions: Self-harm on the internet is a relatively widespread phenomenon among Spanish adolescents. Prevention programs should include emotional regulation, coping skills, and resilience to reduce in this behavior.}, language = {en} } @article{BreitBrunnerPreckel2020, author = {Breit, Moritz Lion and Brunner, Martin and Preckel, Franzis}, title = {General intelligence and specific cognitive abilities in adolescence}, series = {Developmental psychology}, volume = {56}, journal = {Developmental psychology}, number = {2}, publisher = {American Psychological Association}, address = {Washington}, issn = {0012-1649}, doi = {10.1037/dev0000876}, pages = {364 -- 384}, year = {2020}, abstract = {Differentiation of intelligence refers to changes in the structure of intelligence that depend on individuals' level of general cognitive ability (ability differentiation hypothesis) or age (developmental differentiation hypothesis). The present article aimed to investigate ability differentiation, developmental differentiation, and their interaction with nonlinear factor analytic models in 2 studies. Study 1 was comprised of a nationally representative sample of 7,127 U.S. students (49.4\% female; M-age = 14.51, SD = 1.42, range = 12.08-17.00) who completed the computerized adaptive version of the Armed Service Vocational Aptitude Battery. Study 2 analyzed the norming sample of the Berlin Intelligence Structure Test with 1,506 German students (44\% female; M-age = 14.54, SD = 1.35, range = 10.00-18.42). Results of Study 1 supported the ability differentiation hypothesis but not the developmental differentiation hypothesis. Rather, the findings pointed to age-dedifferentiation (i.e., higher correlations between different abilities with increasing age). There was evidence for an interaction between age and ability differentiation, with greater ability differentiation found for older adolescents. Study 2 provided little evidence for ability differentiation but largely replicated the findings for age dedifferentiation and the interaction between age and ability differentiation. The present results provide insight into the complex dynamics underlying the development of intelligence structure during adolescence. Implications for the assessment of intelligence are discussed.}, language = {en} } @article{JuangSchwarzenthalAraletal.2022, author = {Juang, Linda P. and Schwarzenthal, Miriam and Aral, Tuğ{\c{c}}e and Pevec-Zimmer, Sharleen}, title = {Youth experiences of racism and family ethnic-racial socialization in Germany}, series = {Infant and child development : an international journal of research}, volume = {31}, journal = {Infant and child development : an international journal of research}, number = {1}, publisher = {Wiley}, address = {New York}, issn = {1522-7219}, doi = {10.1002/icd.2301}, pages = {14}, year = {2022}, abstract = {In 1988 the youth-led movement "Schools without racism, schools with courage" was established in Belgium and quickly spread throughout Europe.

In this commentary we argue that it should be. With increasing hate crimes and harassment, there is also a need to understand how families are socializing young people to be prepared for, cope with, resist, and disrupt racism. This type of ethnic-racial socialization affects important developmental processes-adolescent ethnic-racial identity development and intergroup and institutional understanding and relations-and requires a more prominent place of study in a migration-diverse Germany. Studying these issues in this particular sociohistorical context will also contribute to a more context-specific understanding of youth experiences of racism.}, language = {en} } @article{BuschingKrahe2020, author = {Busching, Robert and Krah{\´e}, Barbara}, title = {With a little help from their peers}, series = {Journal of youth and adolescence : a multidisciplinary research publication}, volume = {49}, journal = {Journal of youth and adolescence : a multidisciplinary research publication}, number = {9}, publisher = {Springer Science}, address = {New York}, issn = {0047-2891}, doi = {10.1007/s10964-020-01260-8}, pages = {1849 -- 1863}, year = {2020}, abstract = {Peer groups are critical socialization agents for the development of social behavior in adolescence, but studies examining peer-group effects on individuals' prosocial behavior are scarce. Using a two-wave, multilevel data set (N = 16,893, 8481 male; 8412 female; mean age at Time 1: 14.0 years) from 1308 classes in 252 secondary schools in Germany, main effects of the classroom level of prosocial behavior, cross-level interactions between the classroom and the individual levels of prosocial behavior at Time 1, and the moderating role of gender were examined. The results showed that adolescents in classrooms with high collective levels of prosocial behavior at Time 1 reported more prosocial behavior at Time 2, about two years later, reflecting a class-level main effect. A significant cross-level interaction indicated that a high classroom level of prosocial behavior particularly affected individuals with lower levels of prosocial behavior at Time 1. The influence of same-gender peers was larger compared with opposite-gender peers. The findings are discussed with respect to social learning mechanisms in the development of prosocial behavior and their implications for interventions to promote prosocial behavior.}, language = {en} } @article{HoffmannWarschburger2017, author = {Hoffmann, Svenja and Warschburger, Petra}, title = {Weight, shape, and muscularity concerns in male and female adolescents}, series = {The international journal of eating disorders}, volume = {50}, journal = {The international journal of eating disorders}, number = {2}, publisher = {Wiley}, address = {Hoboken}, issn = {0276-3478}, doi = {10.1002/eat.22635}, pages = {139 -- 147}, year = {2017}, abstract = {Objective: The purpose of this study was to examine the impact of age and weight status on adolescents' body dissatisfaction and its change over 20 months in a gender-comparing design. The influence of body image concern on eating concern was also investigated. Method: In a prospective study, 675 male and female adolescents aged 12-16 were assessed using self-report questionnaires on weight, shape, muscularity, and eating concerns. Height and weight measurements were taken by trained personnel. Data were analyzed using structural equation modeling. Results: Analyses of latent means revealed more pronounced weight/shape concern in females than males and more pronounced muscularity concern in males than females. Weight/shape concern increased in females over time, whereas muscularity concern remained stable in both genders. Baseline levels of weight/shape concern could be predicted by age and weight status in females and by weight status in males. The only predictor of change in weight/shape concern was weight status in males. Baseline levels of muscularity concern could be predicted by age in females and by weight status in males. Similar effects were found for changes in muscularity concern in both genders. Increases in weight/shape and muscularity concern were associated with more pronounced eating concern. Discussion: The results confirm gender differences in distinctive facets of body image concern and its prediction. The relevance of increase in body image concern in adolescents is underlined by its association with eating concern in both genders. Further explanatory variables for change in body dissatisfaction should be examined in future studies.}, language = {en} } @article{JungKraheBusching2017, author = {Jung, Janis and Krahe, Barbara and Busching, Robert}, title = {Differential risk profiles for reactive and proactive aggression}, series = {Social psychology}, volume = {48}, journal = {Social psychology}, number = {2}, publisher = {Hogrefe}, address = {G{\"o}ttingen}, issn = {1864-9335}, doi = {10.1027/1864-9335/a000298}, pages = {71 -- 84}, year = {2017}, abstract = {This two-wave longitudinal study identified configurations of social rejection, affiliation with aggressive peers, and academic failure and examined their predictivity for reactive and proactive aggression in a sample of 1,479 children and adolescents aged between 9 and 19 years.

Whereas past research has focused on social reinforcement mechanisms as the underlying processes, the present longitudinal study analysed the role of external control beliefs as an additional mediator explaining the link between peers' acceptance of aggression and the development of aggressive behaviour. Drawing on a large community sample of N = 1,466 male and female children and adolescents from Germany aged between 10 and 18 years, results of latent structural equation modeling were consistent with the hypotheses that peer acceptance of aggression would predict external control beliefs in the social domain, which in turn, should predict aggressive behaviour over time.

We pooled two independently collected longitudinal data sets (N = 760 at Wave 1) and used time-varying effect modeling (TVEM) to show that the frequency of parent-adolescent conflict increased during early adolescence (12 years), peaked at mid adolescence (16 years), and gradually decreased throughout late adolescence and young adulthood. In general, parent-adolescent conflict was associated with negative adjustment (more depressive symptoms and lower GPA) more strongly during mid-to late-adolescence (15 to 17 years) compared with other developmental periods. These time-varying associations differed slightly by gender, at least for GPA. Our findings provide important developmental knowledge of parent-adolescent conflict for Chinese American youth and suggest that attention to conflict and links to adjustment is especially relevant during mid to late adolescence.

It is considered part of the suspicious mindset that may cause highly victim-justice sensitive individuals to behave uncooperatively. Thus, links of victim justice sensitivity (JS) with negative behavior, such as aggression, may be better explained by HAB. The present study tested this hypothesis in N=279 German adolescents who rated their JS, HAB, and physical, relational, verbal, reactive, and proactive aggression. Victim JS predicted physical, relational, verbal, reactive, and proactive aggression when HAB was controlled. HAB only predicted physical and proactive aggression. There were no moderator effects. Injustice seems an important reason for aggression irrespective of whether or not it is intentionally caused, particularly among those high in victim JS. Thus, victim JS should be considered as a potential important risk factor for aggression and receive more attention by research on aggression and preventive efforts.}, language = {en} }
