However, these estimates may be outdated and biased by measurement. The goal of this study was to explore the prevalence of multiple-perpetrator sexual violence and ways to measure it. Data were aggregated across several studies that shared similar methodology in recruiting online, anonymous samples of adults (Table 1). Study 1 evaluated victimization across five samples of 2491 participants. Study 2 evaluated perpetration across four samples of 2699 participants. All participants completed questionnaires in a randomized order. Reported prevalence rates for victimization were higher than prior research (1.5%) and ranged between 2.8% and 10.9% (Table 2) with an average of 4.86% (see Table 3). Multiple-perpetrator victimization items were significantly correlated with other victimization items suggesting validity, phi = 0.182–0.371. Reported prevalence rates of perpetration ranged from 0.8 to 18.9% with an average of 6.43%. Multiple-perpetrator perpetration items were significantly correlated with other perpetration items, suggesting validity, phi = 0.190–0.582. Our findings suggest that multiple-perpetrator sexual violence is more common than previously suggested. Psychometric analyses suggest initial validity, utility, and acceptability for all examined measures that should be further investigated in primary data collections.</p>\u0000 </div>","PeriodicalId":50842,"journal":{"name":"Aggressive Behavior","volume":"51 2","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143513709","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}

A sample of 1053 elementary school students in grades 4–6 across 36 classes completed questionnaires, and a multilevel moderated mediation model was constructed. After controlling for gender and grade, the study found: (1) The association between friendship quality and victimization was the strongest, followed by peer acceptance and peer rejection, with no significant difference between the latter two. (2) Peer acceptance was related to victimization entirely through self-concept, while peer rejection was directly related to victimization. Friendship quality was primarily related to victimization directly rather than through self-concept. (3) Collective efficacy was negatively related to victimization and moderated the relationships between peer rejection, friendship quality, and victimization. Higher collective efficacy reduced the association between peer rejection and victimization but diminished the protective effect of friendship quality on victimization.

Males of this species exist in a dominance hierarchy, where brightly colored dominant individuals aggressively defend territories for reproductive activities. Focal males were presented with visual and chemosensory signals from other males either alone (unimodal) or together (bimodal). We found that vision is necessary for males to engage in aggressive behaviors such as frontal displays, lateral displays, and border fights. While chemical signals alone did not evoke aggressive behaviors, we find slight reductions of some aggressive behaviors when bimodal stimuli are provided.

Data were collected from 655 adolescents using self-reported measures of child abuse, impulsivity, reactive and proactive aggression, attitudes justifying ADV, and ADV perpetration using structural equation modeling.

However, the specific impact of cyber aggression on suicidal ideation and the longitudinal mechanisms remains unclear. Hence, this study sought to address these gaps by applying the general aggression model (GAM). The investigation utilized three-wave longitudinal data with 6-month intervals from a large sample of Chinese emerging adults (<i>N</i> = 1568; 54.7% female; <i>M</i><sub>age</sub> = 19.70 [SD = 1.44], ranging from 17 to 26 years). The random-intercept cross-lagged panel model (RI-CLPM) was employed to explore the roles of depressive symptoms and nonsuicidal self-injury (NSSI) between cyber aggression and suicidal ideation at both the between- and within-person levels. The findings indicated that, at the between-person level, there were trait-like associations between depressive symptoms and cyber aggression, NSSI, and suicidal ideation. At the within-person level, cyber aggression exhibited unidirectional positive cross-lagged effects on depressive symptoms and NSSI, and could subsequently indirectly lead to suicidal ideation via the contemporaneous associations from depressive symptoms and NSSI to suicidal ideation. These results not only align with GAM but also shed light on the underlying mechanisms linking cyber aggression to suicidal ideation.
