The ordered logit model was conducted using a national sample of adolescents aged 12 to 18 in the United States to test the differential effects associated with experiencing bias-based bullying and the buffering role of social support, as suggested by the Minority Stress Theory. From 2015 to 2022, the proportion of students who experienced only non-bias-based bullying remained relatively steady before declining in 2022, whereas the proportion of students who reported being bullied and experienced at least some bias-based bullying showed a gradual upward trend over the same period. Bullying victims who report negative effects are more likely to have low and moderate than high levels of bullying effects. For each level of bullying effects (low, moderate, and high), victims of bias-based bullying have a higher probability of having effects than victims of non-bias-based bullying. Female students are more vulnerable than male students to having high levels of perceived bullying effects on self-esteem, social relationships, schoolwork, and physical health. Social support ameliorates the negative effects of bullying victimization and an increase in social support benefits the victims of bias-based bullying more than the victims of non-bias-based bullying.</div></div>","PeriodicalId":51360,"journal":{"name":"Aggression and Violent Behavior","volume":"85 ","pages":"Article 102091"},"PeriodicalIF":3.4,"publicationDate":"2025-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145262018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contingency learning theories provide a framework for conceptualizing factors that elicit (<em>antecedents</em>) and maintain aggressive (<em>consequences</em>) behavior. For decades, theoretical and etiological models of aggression have emphasized individual differences in neurobiological reactivity during contingency learning as predictors of aggression in youth. However, our ability to predict precisely <em>when</em> aggression will occur and <em>why</em> aggression persists over time remains limited, ultimately hindering our capacity to tailor and personalize interventions to maximize effectiveness. The current review summarizes research examining individual differences in neurobiological reactivity during stimulus-response (<em>antecedents</em>) and response-outcome (<em>consequences</em>) contingencies as predictors of aggression in youth. It then offers concrete recommendations for expansions of this work with an eye toward optimizing the prediction of aggression via the identification of proximal individual- and dyad-level antecedents and consequences. These include conceptual considerations such as examining aggression as a transdiagnostic construct, considering alternative internal and external antecedents and consequences of aggression, and explicating aggression within the dyadic context. Additionally, recommendations for methodological advancements are presented, including enhancing ecological validity of study designs, incorporating ambulatory assessments, and utilizing advanced analytic approaches that allow us to empirically test and identify proximal antecedents and consequences of aggression. Finally, we discuss how these advancements have the potential to increase the precision of intervention efforts to reduce aggression by creating a framework for systematically mapping within-individual and within-dyad processes that elicit and maintain aggressive behavior over time.</div></div>","PeriodicalId":51360,"journal":{"name":"Aggression and Violent Behavior","volume":"84 ","pages":"Article 102082"},"PeriodicalIF":3.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to systematically summarize the worldwide evidence on the prevalence of obstetric violence during childbirth, assess the quality of studies, and explain differences in prevalence rates between studies. To access the studies, the English database of the PubMed, EMBASE, Scopus, Google Scholar, Science Direct, and the Cochrane Central Registry were searched for the period between January 2012 and September 2023. Preferential Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed in reporting the research. Thirty-five studies involving 75,859 women were included in the meta-analysis after searching through different databases. We constructed a prevalence analysis of obstetric violence during labor using a random effects model. The prevalence of obstetric violence during labor ranged from 5.6 % to 91.7 %, while the pooled prevalence rate of obstetric violence during labor was 50.8 % (95 % CI: 44.9–56.7 %).
