Child-to-parent violence (CPV) is a social problem that remains vastly understudied compared with other forms of family violence. The aim of this study is to identify family and child risk and protective factors of CPV, and to investigate whether they differentially predict physical and verbal parent-directed violence among boys and girls. Predictors include parenting behavior during childhood (physical and verbal violence, warmth, monitoring) and respondents' individual characteristics (suicidal ideation, self-control, problematic substance use). Data were examined from a large representative sample of ninth graders ( N = 6,444) in Lower Saxony, Germany. Bivariate analyses showed that female adolescents were more likely to aggress verbally, while no gender differences were found for physical CPV. Multilevel logistic regression models revealed that direct experiences of parental physical and verbal violence during childhood were among the strongest predictors of physical and verbal CPV, both among males and females. While parental monitoring was not significantly associated with CPV, parental warmth protected girls from physical parent-directed aggression. Furthermore, high self-control was protective against verbal CPV as well as boys' physical CPV, while problematic substance use predicted physical violence toward parents in both sexes but only boys' verbal CPV. Suicidal ideation was a risk factor of aggression in males only. Except for parental warmth, the importance of risk and protective factors did not substantially vary across child gender. These findings broaden our understanding of different family and child-related factors that either promote or prevent CPV. Specifically, they point to the importance of the parenting context and especially harsh discipline practices for the occurrence of both physical and verbal CPV.

BackgroundData on the prevalence of suicidal ideation, suicide attempts, and direct self-injurious behavior in adolescents with a migration background are scarce. There are hints that this population is at risk. The aim of the study is to investigate the epidemiology of suicidal ideation, suicide attempts, and direct self-injurious behavior in adolescents with a migration background in Germany while taking gender-specific differences into consideration.MethodsA representative study with N = 10,638 students (mean age 14.91 years, SD = .73).) in the state of Lower Saxony in Germany was conducted. In the 2014–2015 school year, 672 classes were selected by randomly sampling different school types. The participation rate was 84.1%, excluding any classes for which the director refused to provide consent. A total of 49.8% were female adolescents, and 23.3% of the participants had a migration background. Target variables were assessed with items from the Ottawa Self-Injury Inventory, the Self-Harm Behavior Questionnaire and the Self-Harm Inventory, partly adapted.ResultsOf all students, 7.6% had a lifetime history of suicide attempts, and 36.6% answered with a rating of at least “rarely” when asked to rate the lifetime prevalence of suicidal ideation. The 12-month prevalence of direct self-injurious behavior was 17.8%. Adolescents with a migration background showed a significantly higher prevalence of all three constructs (p = .006; p < .001; p = .006). Male students with a migration background reported a significantly higher lifetime prevalence of suicide attempts (4.7% vs. 3.1%) than native males (p = .009). Female students with a migration background reported a significantly higher lifetime prevalence of suicide attempts (15.9% vs. 10.4%) and suicidal ideation (“often” 12.1% vs. 8.9%) than native female students (p < .001; p = .008).ConclusionOur assessment indicates an elevated risk for suicidal behaviors in adolescents with a migration background. From research on adults, it is known that the dominant motives for suicidal behavior in migrants are associated with their migration history/situation. As suggested by Cramer and Kapusta’s (Front Psychol 8:1756, 2017) theoretical model, the Social-Ecological Framework of Theory, Assessment, and Prevention, there is a need for culturally sensitive preventions that take into account the specific reasons for suicide attempts in migrants.Electronic supplementary materialThe online version of this article (10.1186/s12887-019-1404-z) contains supplementary material, which is available to authorized users.

The present study explored whether face-to-face bullying (physical as well as relational), cyberbullying, and teachers' bullying have a negative impact on adolescent's mental health and whether there are gender differences. Analyses are based on a representative cross-sectional standardised survey of 10,638 students of the nineth grade of one federal state of Germany. Findings show that psychological cyberbullying is most strongly associated with poor mental health for both boys and girls. Relational bullying by classmates as well as by teachers also show a significant correlation with poor mental health. For girls, there appears to be an additional relationship between sexual cyberbullying and mental health. Physical forms of bullying were not found to be associated with mental health. Implications for research are discussed.

Based on a survey of 9512 ninth-grade students conducted in Lower Saxony in 2013, this paper examines the prevalence of cyberbullying perpetration and the correlates of this behavior. Binary logistic multilevel regression was used in order to analyze correlates of sexual and psychological cyberbully perpetration. In the preceding semester, 2.4% of the adolescents were perpetrators of psychological cyberbullying and 0.4% bullied someone online sexually. Low levels of empathy, frequent consumption of violent media, and being victims of aggressive online behaviors are correlated with the risk that a child will become a bully. Female adolescents are less likely than boys to engage in sexual cyberbullying perpetration, but they are more likely to engage in psychological cyberbullying perpetration. Only a small share of adolescents engage in sexual and psychological cyberbullying perpetration. Both behaviors differ in their correlates, however being a victim of aggressive online behaviors increase the risk for perpetration of both behaviors, respectively.

The aim of this study was to investigate how classroom normative climate regarding the perpetration of teen dating violence (TDV) was related to adolescents’ self-reported perpetration of (verbal/emotional, threatening, relational, physical, and sexual) violence within romantic relationships in the previous 12 months. Based on Theory of Normative Conduct, we hypothesized that higher classroom levels of TDV perpetration were associated with a higher likelihood of individual TDV perpetration. Data were drawn from a large survey of ninth-grade students conducted in the state of Lower Saxony, Germany ( n = 10,638). From this sample, an analysis sample of n = 4,351 students at risk was drawn (mean age: 15.0, SD: 0.76; 46.6% male). More than half (54.8%) of the at-risk sample reported engagement in any form of TDV within the previous 12 months, whereby rates varied considerably by the dimension of TDV. Controlling for a range of risk factors on the classroom level (proportion of students dependent on social welfare, proportion of students with migration background) and individual level (exposure to family violence, sociodemographic characteristics, TDV victimization, and peer- and school-related factors), regression analyses showed that higher rates of classroom-level TDV perpetration were positively related to individual verbal/emotional TDV perpetration. This pattern of results was observable across all dimensions of TDV. Furthermore, gender-specific patterns of TDV perpetration were observable: Girls were more affected by classroom levels of verbal/emotional and physical TDV than boys, while boys were more affected by classroom levels of relational and sexual TDV. Results highlight the role of the wider peer context in shaping adolescent dating experiences and specifically point to the relevance of the classroom ecology for the socialization of dating violence in adolescents.

The Internet has simplified daily life activities. However, besides its comfortability, the Internet also presents the risk of victimization by several kinds of crimes. The present article addresses the question of which factors influence cyber-dependent crime and how they vary between three kinds of cyber-dependent offences: malware infection, ransomware infection, and misuse of personal data. According to the Routine Activity Approach, it is assumed that crime is determined by a motivated offender, the behavior of the Internet user, and the existence of prevention factors. Our analyses were based on a random sample of 26,665 Internet users in two federal states in Germany, aged 16 years and older; 16.6 percent of the respondents had experienced at least one form of cyber-dependent victimization during the year 2014. The results indicate that individual and household factors, as well as online and prevention behavior, influence the risk of cyber-dependent victimization. Furthermore, the effects differ between the three types of offences. In conclusion, the risk of being victimized by cyber-dependent crime is not the same for anyone, but depends on multivariate factors according to the idea of Routine Activity Approach. However, in view of the fact that crime-related factors also matter, studying different cybercrime offences separately seems to be an appropriate research approach.

Callous-unemotional (CU) traits represent the affective components of the psychopathy construct and show a strong relationship to violence and conduct-disorder in children. The Inventory of Callous-Unemotional Traits (ICU) is the current standard to assess CU traits. Despite the ICU having originally been constructed as a four-dimensional instrument, several studies found a threefactorial structure in combination with a general ICU-factor to be the best fitting factor-model. An imbalance in the number of positively and negatively worded items can be observed between the identified ICU dimensions. To investigate the effect of item keying on the factor structure we tested different factor-models in data stemming from a large sample (N = 3878) of German ninth grade students. Our findings suggest that the original four-factorial structure with a method factor shows good model fit. This solution is furthermore in line with the specifiers of the additional coding of Limited Prosocial Emotions for Conduct Disorder in the DSM-V.

Inmate-on-inmate violence is a serious problem in prisons and young offender institutions. However, most studies on predictors of violent misconduct have focussed on adult inmates. This study examines the perpetration of violence in multiple young offender institutions, using the selfreport data of 865 male inmates. Prevalence rates indicate that violence occurs to a high extent in the institutions. Regression analyses show that both importation and deprivation variables significantly predict the perpetration of physical and sexual violence. Specifically, drug use during imprisonment, violent beliefs, and a negative inmate-staff relationship were found to increase the risk of violent misconduct. The implications of these findings are discussed.
