However, this hypothesis is mainly supported by cross-sectional studies, while longitudinal research on bullying and empathy is still scarce.

Results from 1228 elementary school students (52.92% boys; <i>M</i>age = 10.19, SD = 1.13) indicated that the associations between bullying and empathy are different for boys and girls. For boys, cognitive and affective empathy are negatively associated with bullying at the between level. At the within level, the only significant cross-lagged path indicated that a positive deviation from the expected score of cognitive empathy at baseline predicted a positive deviation from the expected score in bullying behavior 5 months later. For girls, there were no associations between empathy and bullying at either the within- or between-level. This study calls for further clarification of the direction of the relation between bullying and empathy before incorporating it into prevention programs.</p>","PeriodicalId":50842,"journal":{"name":"Aggressive Behavior","volume":"51 3","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ab.70026","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this longitudinal study, we tested the reciprocal impacts of parental conflict and aggressive behavior, considering the role of poor family functioning in these two aspect. Three measurements were conducted on 540 adolescents (<i>M</i><sub>age</sub> = 12.57, SD = 0.68) in China, with a 6-month interval for each measurement. The first measurement was conducted in September 2022, the second in March 2023, and the third in September 2023. Adolescents' perception of the interparental conflict scale, family assessment device functioning scale, and direct and indirect aggression scale were used. Parental conflict at Waves 1 and 2 positively predicted poor family functioning and aggressive behavior at Waves 2 and 3, respectively. Poor family functioning at Waves 1 and 2 positively predicted aggressive behavior at Waves 2 and 3, while aggressive behavior at Waves 1 and 2 positively predicted poor family functioning at Waves 2 and 3. These results indicated the reciprocal relationship between poor family functioning and aggressive behavior. Additionally, the mediation analysis revealed that poor family functioning at Wave 2 serves as a mediator in the unidirectional association between parental conflict at Wave 1 and aggressive behavior at Wave 3. These findings indicated that poor family functioning partially accounts for the unidirectional predictive relationship between parental conflict and aggressive behavior over time.

In this first survey on animal abuse carried out in higher education in France and based on a highly powered sample (<i>N</i> = 55,040 participants), we investigated the relative weight of risk factors pertaining to major criminological dimensions in a multivariate model controlling for relevant demographics: General Strain Theory (GST), Social Bond Theory (SBT), and Generalized Deviance Theory (GDT), as well as three key psychological dimensions: Callousness, Sensation seeking, and Impulse control difficulties. We observed that 6.4% of the participants declared having perpetrated animal abuse in the past, with males having done so about three times more often than females. Animal abuse was linked with callousness, difficulties in impulse control and sensation seeking. Participants who reported a climate of violence in their family, or who had witnessed acts of violence by their father against their mother, were particularly prone to abuse animals, which supported GST predictions. To a lesser extent, in line with SBT, animal abuse was higher among students with lower attachment to their mother, and who had a weaker belief in justice. Finally, animal abuse was perpetrated significantly more often by participants reporting higher alcohol consumption, as predicted by GDT. In summary, animal harm is related to a combination of risk factors pertaining to major criminological and psychological perspectives on aggression and violence, knowledge of which is useful in prioritizing future research directions and prevention strategies.</p>","PeriodicalId":50842,"journal":{"name":"Aggressive Behavior","volume":"51 3","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ab.70028","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
