The aim of the current systematic review and meta-analysis was to examine the prevalence and incidence of somatoform symptoms and disorders (also referred to as medically unexplained symptoms, psychosomatic symptoms, functional syndromes, somatization disorder, or somatic symptom disorder) in childhood and adolescence. The PRISMA guidelines were followed, and the review was registered prior to initiation (PROSPERO CRD42022339735). Fitting search terms were entered in Web of Science, Scopus, and PubMed in June, 2022. Included were articles, reports, book chapters, and conference papers that reported on the prevalence or incidence rates of somatoform symptoms and disorder in under-18-year-olds with empirical primary data; these needed to be published in English or German. Publications were excluded if they focused on abuse, trauma, serious illness, or hypochondria, as well as if they had a qualitative or experimental (intervention) study design. To be included in the meta-analysis, studies needed to report values suitable to calculate a pooled prevalence or incidence rate. After the full-text screening, 33 articles remained, of which 29 were used for the meta-analysis. The quality evaluation criteria proposed by Loney and colleagues (1998) were utilized for quality assessment. The pooled global prevalence rate was 31.0% for somatoform symptoms and 3.3% for somatoform disorders, yet heterogeneity remained high. The noteworthy prevalence rates have important implications for healthcare professionals, as well as school nurses and counselors.

Bullying is a major social problem that is receiving increased attention in society and research. The overarching goal of the current study was to identify risk and protective factors of bullying examining direct effects between peer relationship, emotion regulation, and bullying involvement. Therefore, a cross-sectional study was conducted with students (55.7% female) between the ages of 10 and 15 ( ; ). Path model analysis revealed that trust had a negative effect on victimization, dysfunctional emotion regulation had a positive effect on perpetration and victimization, alienation had a positive effect on dysfunctional emotion regulation, and victimization and communication had a positive effect on functional emotion regulation. Additionally, dysfunctional emotion regulation strategies mediate the path from alienation to bullying and to victimization. Study results underline the importance of considering the bullying dynamic from a combined perspective of intra- and interindividual factors. The results partially confirmed the hypotheses and contribute to our knowledge about individual and contextual correlates of bullying in adolescents. The present findings suggest that group facilitation with the entire class in team building could be a useful intervention to strengthen peer relationships as well as the relationships between classmates and teachers and students.

Background: The development of morality is vital for fostering prosocial behavior and enhancing both individual and societal well-being. Clarifying what contextual and individual factors play a role in moral processes during childhood can contribute to our understanding of the development of morality. Given the previous acknowledgment of importance, yet lack of existing empirical findings, the study focused on the significance of callous-unemotional traits (i.e., an affective-interpersonal personality trait, related to psychopathy in adulthood) and emotion regulation (i.e., an essential part of socio-emotional competence, and a transdiagnostic factor in the development of psychopathology) for moral emotions and cognitions during middle childhood. The concrete aim was to examine direct and indirect effects of callous-unemotional trait dimensions (callousness, uncaring, unemotionality) onto immoral emotional attribution (i.e., feeling good after immoral decisions) and admissibility of immoral actions (i.e., evaluating immoral actions as being okay) via emotion regulation skills. Methods: A cross-sectional study was conducted with 194 children attending Grades 1 to 4, and their primary caregivers. The children completed the Inventory of Callous-Unemotional Traits and caregivers completed the Emotion Regulation Checklist. The children were also presented with a set of moral dilemma vignettes, and asked about the emotions of protagonists who acted immoral, and the admissibility of their actions. Results: Path-model analysis revealed (1) negative direct effects of emotion regulation skills onto immoral emotional attribution and admissibility of immoral actions, (2) positive direct effects of the dimensions callousness and uncaring onto immoral emotional attribution and admissibility of immoral actions, and (3) negative direct effects of dimensions callousness and uncaring onto emotion regulation skills. Indirect effects, indicating that emotion regulation skills mediate the association between the callous-unemotional trait dimensions and morality, were also found. Conclusion: The findings address a knowledge gap and indicate that emotion regulation skills, callousness, and uncaring play an important role in morality in middle childhood and should be included in frameworks of moral decision-making and development.

The moral self is increasingly being debated in research, i.e., what causes children to internalise and evaluate the importance of certain moral values. The aim of the present study is to analyse associations between parental warmth and harsh parenting, temperamental self-regulation (inhibitory control and impulsivity), and the moral self in middle childhood. A total of 194 (n = 52 children with special educational needs in emotional–social development) six- to eleven-year-old children (M_age = 8.53, SD_age = 1.40) and their primary caregivers (M_age = 40.41, SD_age = 5.94) participated in this cross-sectional questionnaire study. Parental warmth and impulsivity were associated with the moral self. Impulsivity mediated the relationship between harsh parenting as well as parental warmth and the moral self. Results are discussed in terms of their relevance to social information processing theory. The importance of parenting and temperamental self-regulation is discussed as implications that may in turn strengthen children’s moral selves.

The COVID-19 pandemic has resulted in rapid, unprecedented changes in the lives of children and adolescents worldwide. During the first year in the COVID-19 pandemic German schools were partially closed. The restrictions to limit the pandemic can be viewed as incongruent with developmental tasks of children and adolescent, and this can harbor risks such as loss of education, well-being, and daily structure. Additionally, social skills could decrease. The current study analyzed behavioral changes in traditional bullying and cyberbullying, externalizing behavior problems and prosocial behavior from spring 2020 (pandemic outbreak) to spring 2021 (during the pandemic; a time when schools were closed and infection rates peaked). We addressed our research question with an online survey in a German sample. A total of 130 students (65 females and 65 males) with ages ranging from 10 to 17 (M_T1 = 13.88; SD_T1 = 1.26) participated. Our results revealed significant differences in cyberbullying and prosocial behavior and no significant differences in traditional bullying and externalizing behavior problems across one year. Cyberbullying increased and prosocial behavior decreased during the first year of pandemic.
