Combating the recent surge of anti‐Asian racism requires a collective effort that includes the willingness of nontarget bystanders to intervene, but little is known about the circumstances under which they are willing to do so. The present qualitative study explores why non‐Asian bystanders decide to intervene when they witness anti‐Asian racism, and why, under other circumstances, they choose not to. Twenty semi‐structured interviews were conducted with non‐Asian college students who witnessed anti‐Asian discrimination. Guided by the five‐stage sequential decision‐making framework of bystander intervention, we analyzed intervention as a series of stages: seeing the event, recognizing it as worthy of intervention, determining one's responsibility for acting, deciding how to act, and, finally, executing on that plan. The respondents recounted a diverse range of situations and factors in each stage that impacted why they intervened or not. Our findings suggest that the act of intervening increases the bystander's confidence and desire to intervene again in the future. Given the complexity of the bystander decision chain and the compressed timeframe in which it often occurs, we conclude that training on bystander antiracist intervention might benefit from being structured according to the multi‐stage model.

Gratitude is associated with increased social integration, which may counter the loneliness stemming from repeated peer victimization. The gratitude youth feel after different types of bystander action may depend on which behaviors are most congruent with personal beliefs. Face and honor cultures provide social norms for expectations and interpretations of behavior, including how to act during and after interpersonal conflict. In the current study, 264 ethnically diverse adolescents (African, European, Mexican-American, and Indigenous) from the Pacific Northwest described past instances when they experienced an act of peer-instigated aggression and subsequent bystander action. We examined how face and honor endorsements predicted victims' gratitude following three different types of bystander action (calm, avenge, and reconcile). Face endorsement predicted higher gratitude for being calmed, whereas honor endorsement predicted higher gratitude for being avenged. Bystander efforts to reconcile conflict elicited the most gratitude but were not related to social norm endorsement. Our findings shed light on the association between social norm endorsement and victimized youths' gratitude for their intervening peers' bystander actions. [ABSTRACT FROM AUTHOR]

This study examines the factors shaping individuals’ reactions to health-protective norm violations through the lens of cognitive accessibility, the risk-as-feelings hypothesis, and the tripartite decision-making framework. By surveying 1,426 U.S. college students, we found that frequent exposure to health information in the media is associated with an increased tendency to adopt health-protective measures and support bystander intervention (upstanding) intentions. From a theoretical perspective, the results underscore the significant impact of the conative (behavioral) dimension on bystander intervention intention, alongside contributions from the affective and cognitive dimensions. Health communication practitioners should plan frequency-enhancing media strategies to effectively reach their target audience. Well-targeted and repeated exposure to vaccine information may help address health norm violations by correcting deviant behaviors. [ABSTRACT FROM AUTHOR]

Objective: Sexual assault (SA) is unfortunately common in U.S. college campuses. Friends are central to the social context of college women, and thus to the context of SA, and thus may play a key role in SA prevention. The objective of the present study was to provide a preliminary test of a novel friend-based motivational intervention (FMI) that encourages and prepares friends to work together to reduce SA risk. Method: In a pilot trial, 51 friend dyads (N = 102) were randomized to either FMI or waitlist control (WLC) conditions and then followed over 3 months. Participant perceptions of the intervention and intervention-associated outcomes (engagement in friend-based assault protective behaviors [FAPB], readiness to change, barriers, sexual assault occurrences) were examined. Results: Those in the FMI reported greater readiness to engage in efforts to protect their friend against SA and reported higher rates of FAPB across time points relative to the WLC. Though not statistically significant, women in the FMI also reported half as many incidences of SA at the 3-month follow-up. We did not observe decreases in perceived barriers to intervening that were targeted with the FMI. Participant feedback on their experiences with the FMI was positive; women reported that FMI was empowering, personally relevant, and useful. Conclusions: Findings point to the promise of this dyad-based motivational intervention that capitalizes on the natural resource of women's friendships to decrease risk for sexual assault. What is the public health significance of this article?: This randomized controlled trial provided a preliminary test of a friend-based motivational intervention that encourages and prepares friends to work together to reduce sexual assault risk. Findings suggest that friend-based motivational intervention is a novel and promising way to empower female friends to work together to decrease risk for sexual assault—a pervasive public health problem for young adult women in the United States.

Introduction: Optimizing the clinical learning environment (CLE) is a medical education priority nationwide. Materials and Methods: We developed a virtual, one-hour workshop engaging students, housestaff and faculty in small-group discussions of five case scenarios adapted from reported unprofessional behaviors in the CLE, plus didactics regarding mistreatment, microaggressions and bystander interventions. Results: Over two sessions (2021–2022), we engaged 340 students and 73 faculty/housestaff facilitators. Post-session surveys showed significant improvement in participants' ability to recognize and respond to challenges in the CLE. Discussion: Our innovative workshop, including scenarios derived from institutional reports of unprofessional behaviors, advanced participants' knowledge and commitment to improve the CLE.

Bystanders play an essential role in school bullying prevention. This study examines student bystanders' perceptions of severity and willingness to intervene in scenarios involving physical, verbal, relational, and cyberbullying. It focuses on five distinct victim reactions: pretending nothing happened, seeking help, fighting back, crying, and no description as a control group. Using a combination of four bullying types and five victim reaction forms, a survey experiment comprising 20 scenarios (4 × 5) was designed and conducted among primary, middle, and high school students in China (N = 5,075), aged between 8 and 19 years (M = 14.07; SD = 2.10) in 2019. The reactions of victims significantly influenced how bystanders perceived the severity of bullying events and their willingness to intervene. Overall, victims who responded with "crying" evoked a greater intention to intervene among bystanders, while those who "fighting back" or "pretending nothing happened" were seen as less severe. These findings enhance our understanding of bystanders' perspectives on victim responses across different types of school bullying. The outcomes of this study can contribute to the development of more specific antibullying program strategies in practical applications. [ABSTRACT FROM AUTHOR]

During the Holocaust, thousands of Jews in France fled Europe via Franco's Spain. When leaving France, refugees who lacked the required travel documents avoided police and customs officers at the Franco-Spanish border by walking over the Pyrenees. Guides (passeurs) led them through the mountains to the border, choosing trails and times that would make encounters with police patrols less likely. Most charged large sums of money, but some worked without payment. This article explores why the latter group engaged in this dangerous form of rescue, by examining how they became border guides. It focuses on two French farmers, a French Christian brother at a sanatorium, and an antifascist activist from Germany. The sources analyzed include the memoirs, unpublished accounts, diaries, letters and oral history interviews of the guides, their work associates, and the refugees; as well as official correspondence between French police and government officials in the Pyrenees region, and the archival records of the Brothers of the Christian Schools. The author's primary research finding is that the border guides considered in this study undertook the dangerous task of guiding refugees because they had had a series of experiences and had engaged in a series of actions that made it more feasible for them to do so when asked. Their values and understanding of their work also help explain why they became guides. Reflections on the implications of this research for our comprehension of bystanders' actions conclude the article. [ABSTRACT FROM AUTHOR]

In recent years, social campaigns and high-profile cases have brought increased attention to violence against women. Athletes can be role models, shaping both prosocial and antisocial attitudes. Their engagement in violence prevention could be an effective tool to tackle violence against women through bystander intervention. This part of a mixed-method feasibility study reports on the quantitative evaluation of an evidence-led bystander program, Football Onside, implemented at a football club in South West England in June 2018 to February 2020. The study employed a quasi-experimental design with intervention and control groups. Football coaches and club members (n = 50) completed measures of rape and domestic abuse myths, bystander intent and efficacy, self-reported bystander behaviors, readiness for change, perceptions of peer helping and myth acceptance, law knowledge, and program evaluation. Fidelity was also assessed. The analysis compared between- and within-group differences in mean changes over time using mixed-effects models. Participant ratings of learning outcomes were high, and fidelity was maintained throughout the intervention. Between-group comparison revealed mixed results, with greater improvements in the intervention group for bystander intent and efficacy at post-test and follow-up, domestic abuse myths at post-test, and rape myth acceptance at follow-up. Model contrasts for within intervention group revealed improvements in rape and domestic abuse myth acceptance, bystander intent and efficacy, perceived law knowledge at both time points, and perceived peer myths and helping at post-test. At follow-up, intervention participants reported significantly higher engagement in bystander behaviors. No significant effects were found for perceived importance of legal knowledge. Our research highlights the potential efficacy of a bystander program tailored for football club members. Cluster-randomized control trials are now required to examine bystander attitudes and behavior change processes among professional athletes. [ABSTRACT FROM AUTHOR]

Willingness to intervene as an effective bystander is critical in preventing partner violence and fostering safety among college students. Informed by the Social Determinants of Health framework, this conceptual paper provides an overview of the background and historical evolution of bystander intervention and invites a rethinking of how various factors impact bystander intervention for partner violence among college students by highlighting the roles of (1) economic factors and education, (2) sexual beliefs, myths, and media, (3) gender values and norms, (4) environmental factors, (5) college students at risk, (6) social support network and access to services, (7) acculturation and familiarity with the U.S. culture, and (8) cost-benefit analyses. We also discuss potential practice, research, and policy implications. Understanding the Social Determinants of Health is instrumental in addressing the root cause of intersecting health disparities, which is vital in preventing violence, encouraging bystander intervention, and creating a safer community.

AbstractThis study investigated the bystander effect by examining intentions to intervene in simulated Facebook Live scenarios. A 4 (number of other viewers: 0 vs. 4 vs. 49 vs. 224) x 2 (level of urgency: non-urgent vs. urgent video) between-subjects experimental design was conducted with 210 participants to examine how the number of bystanders and the perceived urgency of a situation influence self-reported bystander intentions. With individual empathy levels controlled, an ANCOVA test revealed no significant main effect of the number of other viewers on the intention to intervene, but a significant difference was found between the 0 and 224 viewer conditions. Urgent situations elicited higher intervention intentions compared to non-urgent ones, without an interaction effect with viewer number. With the number of other viewers and urgency level as separate independent variables, mediation analysis found patterns differing from the traditional five-step bystander intervention model. These findings enhance our understanding how bystander intentions manifest in social media contexts and highlight the influence of perceived danger and audience size. The implications for online bystander behavior and future research directions are discussed. [ABSTRACT FROM AUTHOR]

The prevalence of sexual assault (SA) among college students (13%) is unacceptable, underreported, and alcohol use by the perpetrator or victim is reported in 50% of SA cases. Bystander intervention (BI) programs, which use prosocial behaviors to prevent or stop a harmful situation from occurring, have been implemented across college campuses to reduce SA. There are several known barriers (e.g. self-intoxication) and facilitators (e.g. peer support) to BI for SA; however, less is known about barriers and facilitators to BI for alcohol-related SA. Alcohol-related SA includes situations in which the perpetrator and/or victim are intoxicated, whereas alcohol-facilitated SA includes situations in which individuals intentionally use alcohol as a perpetration strategy. The current study examined student perspectives of BI for SA opportunities, actions taken in response to opportunities, and barriers and facilitators to action. The team conducted content and deductive thematic analysis of data from focus groups and interviews with diverse undergraduate students (N = 79). Opportunities included perpetrator-focused, victim-focused, and sexual risk opportunities. Actions taken included staying vigilant, monitoring friends, communicating with friends, and removing friends. Barriers included self-intoxication, feeling helpless, peer pressure, not feeling personally responsible, and fearing the consequences of helping. Finally, facilitators included knowing friends’ concerning signals and drinking motives, feeling like some intervention strategies are easy, understanding sex-related risks, acknowledging consent and personal boundaries, and feeling personally responsible for friends. Understanding these situations’ nuances can help to inform more effective and comprehensive BI programs to reduce SA. [ABSTRACT FROM AUTHOR]

Studies on bystander behaviour showed that bystanders regularly intervene in conflicts and crime in public in order to de-escalate, yet these studies focus solely on the way citizens manage situations in the absence of police. Bystanders, however, are also present while police officers carry out their work and might help or challenge their performance. Based on 15 interviews with police officers and participant observation during 12 police shifts in the Netherlands, this study provides insights into the way officers perceive bystanders and experience their actions. Police officers describe bystanders as a dilemma they have to face during encounters: they want to convey a positive and fair image of themselves towards bystanders, yet also want to control the situation and show their authority. The diversity of bystander actions and the dilemma's officers face imply that more attention should be given to bystanders of police action in both research and training. [ABSTRACT FROM AUTHOR]

Background: The opioid crisis is a serious public health issue in Canada. There have been many surveillance programs and research studies on opioid-related emergency department (ED) visits at a national, provincial, regional or municipal level. However, no published studies have investigated the in-depth contexts surrounding opioid-related ED visits. In addition, few studies have examined injuries other than poisonings in those visits. The objective of this study is to investigate the contextual factors and co-occurrence of poisonings and injuries among the opioid-related ED visits in a Canadian sentinel surveillance system on injuries and poisonings from 2011 to 2022. Methods: This study used a mixed methods design. The data source was the Canadian Hospitals Injury Reporting and Prevention Program. We first selected all opioid-related ED visits during our study period and then identified the contextual factors through a content analysis of the combination of the narrative description and other variables in the patients' records. The contextual factors were organized into themes as opioid use context, social resource utilization, bystander involvement, and prior naloxone use. The opioid use context was used as a co-variable to examine the other themes and ED presentations (poisonings and other injuries). Quantitative descriptive approach was used to analyze all the contexts and ED presentations. Results: The most common opioid use context was non-prescribed opioid use without intention to cause harm, followed by self-poisoning, children's exposure, and medication error. Various rare contexts occurred. Paramedics participated in 27.9% of visits. Police and security guards were involved in 5.1% and 2.3% of visits, respectively. Child welfare or social workers were involved in 0.4% of visits. Bystanders initiated 18.9% of the ED visits. Naloxone use before arriving at the ED occurred in 23.4% of the visits with a variety of administrators. The majority of patients presented with poisoning effects, either with poisoning effects only or with other injuries or conditions. Conclusions: Our study has provided an in-depth analysis of contextual factors and co-occurrence of poisonings and injuries among opioid-related ED visits in Canada. This information is important for ED programming and opioid-related poisoning and injury intervention and prevention. [ABSTRACT FROM AUTHOR]

Introduction: The Advancing Research To Eliminate Mental Illness Stigma (ARTEMIS) study evaluated the impact of an intervention developed and implemented in Singapore on attitudes towards depression in university students. We aimed to assess the likelihood of university students intervening when their peers suffer from depression, before and after the ARTEMIS intervention. Methods: 390 students were recruited from a university in Singapore. The ARTEMIS intervention comprised a lecture by a trained mental health professional, a sharing session by a person with lived experience of depression, and a question-and-answer segment with a panel. The Bystander Intervention Scale for Depression (BISD) was administered at baseline, post-intervention, and 3-month follow-up. BISD assessed four factors: acceptance of responsibility to intervene, knowledge on how to intervene, awareness of depression among peers, and vigilance towards possible symptoms of depression. Linear mixed models were conducted to investigate associations. Sociodemographic correlates were also examined. Results: A favourable shift in all factors was observed at post-intervention, which weakened at 3-month follow-up. Having past experience in the mental health field (b=1.50) and older age (b=0.18) were significantly associated with knowledge on how to intervene. Having social contact with mental illness (SCMI) and past experience in the mental health field (PEMHF) were significantly associated with awareness of depression among peers (SCMIb=0.89, PEMHF b=0.43) and vigilance towards possible symptoms of depression (SCMI b=0.39, PEMHF b=0.61). Discussion: The short-term results of the intervention appeared promising across all BISD factors; however, these results were not sustained after 3 months. Future research should include the impact of 'booster' interventions over time. Sociodemographic factors that were identified to be significant correlates should also be considered when planning for future interventions. [ABSTRACT FROM AUTHOR]

As powerful activators of the immune system, cytokines have been extensively explored for treating various cancers. But despite encouraging advances and some drug approvals, the broad adoption of cytokine therapies in the clinic has been limited by low response rates and sometimes severe toxicities. This in part reflects an inefficient biodistribution to tumors or a pleiotropic action on bystander cells and tissues. Here, we first review these issues and then argue for the intratumoral delivery of engineered cytokine fusion proteins that have been optimized for tumor retention as a potential solution to overcome these limitations and realize the potential of cytokines as highly effective therapeutics for cancer.

Police encounters with suspects may produce unfortunate outcomes, particularly when defiance of authority leads to usage of force. Application of excessive force may be interrupted, or obviated by the actions of bystander officers who become intervening officers. This study evaluated officer and supervisor perceptions of a training program which taught intervention strategies and tactics to help officers intervene with other officers to prevent harm. Data were collected very early in program implementation and approximately one year later. Survey data were collected with officers and qualitative focus groups were conducted with officers and supervisors. Findings indicate a marked change in perceptions by officers. Both quantitative and qualitative findings collected in early phase indicate a high degree of officer resistance. Late phase data indicate significantly higher endorsement of officer intervention strategies and participants reported higher frequencies of intervening with other officers. Findings suggest officer-based de-escalation and intervention training warrants implementation consideration from agency decision makers. [ABSTRACT FROM AUTHOR]

Introduction Addressing hazing within the U.S. Military has become a critical concern to safeguard the well-being of service members; recent attempts to assess hazing prevalence in the military have been unsuccessful due to under representative data. Methods To delve into the hazing climate and reporting culture at Fort Bragg, now Fort Liberty, 227 individuals took part in an anonymous online survey. The survey collected demographics and insights on hazing attitudes and behaviors, perceptions of group experiences including hazing/non-hazing activities, views on leadership, familiarity and experiences with reporting procedures, and bystander intervention. Results The findings echoed existing literature: while only 17.2% admitted to experiencing hazing, a striking 70.3% acknowledged involvement in specific hazing behaviors. Only 40% of participants who acknowledged experiencing hazing (n  = 35) disclosed that they reported or confided in someone about the incident. Responses highlight reporting hurdles including concerns about anonymity, confidence in the reporting process, leadership reactions to reports, and the normalization of these events as tradition. Discussion Distinct elements of military culture, such as the hierarchical chain of command, loyalty to the brotherhood/sisterhood, and the emphasis on resilience, likely amplify these responses. This study adds to the mounting evidence showcasing gaps in assessing hazing within the U.S. Military. It emphasizes the necessity for a comprehensive hazing prevention program. Presently, prevention relies on mandatory training, often integrated into safety briefings or harassment workshops. However, service members require further assistance in recognizing, rejecting, and reporting instances of hazing despite these trainings. [ABSTRACT FROM AUTHOR]

The incidence and nature of sexual violence at UK universities has been aligned with a 'rape culture', where sexual violence is taken-for-granted. Calls to change such a culture permeate literature from government, charities, regulatory bodies, and academia. This paper pulls out of the literature the strategies called to change rape culture. Focusing on three overarching strategies: naming sexual violence, reporting sexual violence, and preventing sexual violence. We carried out a website analysis of all UK universities that focused on gathering data along these three themes to ascertain the extent to which their websites supported changing the culture of sexual violence at their university. Many universities' websites had an online reporting tool and defined sexual violence, but many universities' websites did not have information about bystander initiatives (the prevention strategy we focused on). The research raises implications for universities to enhance their website pages for in-person bystander initiatives and to standardise definitions of sexual violence used in online reporting tools. Consequently, more research is needed into what definitions of sexual violence are used, the type of language used and the efficacy of online reporting tools. [ABSTRACT FROM AUTHOR]

Hate is widespread online, hits everyone, and carries negative consequences. Crowd moderation—user-assisted moderation through, e. g., reporting or counter-speech—is heralded as a potential remedy. We explore this potential by linking insights on online bystander interventions to the analogy of crowd moderation as a (lost) public good. We argue that the distribution of costs and benefits of engaging in crowd moderation forecasts a collective action problem. If the individual crowd member has limited incentive to react when witnessing hate, crowd moderation is unlikely to manifest. We explore this argument empirically, investigating several preregistered hypotheses about the distribution of individual-level costs and benefits of response options to online hate using a large, nationally representative survey of Danish social media users (N = 24,996). In line with expectations, we find that bystander reactions, especially costly reactions, are rare. Furthermore, we find a positive correlation between exposure to online hate and withdrawal motivations, and a negative (n-shaped) correlation with bystander reactions. [ABSTRACT FROM AUTHOR]

Summary: Bystander intervention has been promoted across organizations to combat sexual harassment and its deleterious effects. However, the career consequences of bystander reporters (e.g., their hireability prospects inside and outside the organization)—those who report sexual harassment on behalf of coworkers—are not well understood. Based on the social identity and person perception literatures, which suggest that recruiters are motivated to hire candidates with attributes helpful to the organization (perceived moral character and agreeableness), we proposed that candidates' history of reporting sexual harassment on behalf of a victim leads to perceived high moral character but low agreeableness, which subsequently have countervailing effects on hireability of these known reporters. We found support across three experimental studies using realistic hiring decision‐making tasks and various employee samples. Based on the social identity literature, we further argued that perceptions and hireability of the known reporters depend on recruiter and candidate genders. In Study 2 and Study 3, we consistently found that the positive effect of reporting on perceptions of candidate moral character was weaker when the recruiter was male (vs. female) but we found mixed results for candidate gender effects. Theoretical and practical implications of these results are discussed. [ABSTRACT FROM AUTHOR]

Reporting workplace discrimination has garnered renewed attention in public administration scholarship. Missing, however, from the literature is bystander reporting, a relatively new and understudied mode of reporting. Using a sub-sample of respondents (i.e., bystanders) who witnessed others encountering workplace discrimination—specifically race- (n = 886) and/or sex-based discrimination (n = 1,152)—this study finds that less than one fifth (18.7% and 16.6% respectively) of all bystanders reported the alleged offense. However, this study suggests that personal characteristics such as age, race or ethnicity, and veteran status, as well as occupational variables such as supervisory status and tenure duration, significantly impacted bystander reporting after witnessing race-based discrimination. Likewise, personal characteristics such as age, as well as occupational variables such as grade level, supervisory status, and tenure duration, also significantly impacted bystander reporting after witnessing sex-based discrimination. These findings are important because a different mode of reporting may increase agency accountability for acts of workplace discrimination or retaliation. [ABSTRACT FROM AUTHOR]

Guardianship is a core tenet of routine activity theory and collective efficacy. At its outset, routine activity research assumed that the mere presence of a guardian was sufficient to disrupt many forms of crime. More recent research, however, has taken as a starting point that would‐be‐guardians must take on an active role for a reduction in crime to occur. Integrating research on bystander intervention and guardianship‐in‐action, the current study elaborates the individual‐level motivations and decision processes of guardianship to answer the following questions: Who serves as a reactive guardian? How do they do so? And why? We tasked young adults (N = 1,032) included in the recent waves of the Zurich Project on the Social Development from Childhood to Adulthood (z‐proso) to assess a 70‐second video depicting a sexual harassment event. We examined participants' willingness to engage in a range of intervention options as a function of their prosocial attitudes, safety considerations, socioemotional motivations, and moral considerations. Results show a complex decision process leading to whether and how a would‐be guardian decides to intervene to disrupt sexual harassment, such that prosocial motivations and emotional reactions are weighed against perceptions of danger when deciding on a specific course of action.

Most adolescents and young adults frequently encounter hate speech online. Although online bystander intervention is essential to combating such hate, young bystanders may need support with initiating interventions online. Thus, to illuminate the factors of young bystanders' intervention, we conducted a nationwide, quota-based, quantitative online survey of 1180 young adults in Germany. Among the results, perceived personal responsibility for combating online hate speech positively predicted online bystanders' direct and indirect intervention. Moreover, frequent exposure to online hate speech was positively associated with bystander intervention, whereas, a perceived threat or low self-efficacy reduced the likelihood of intervention. Also, a greater acceptance of negative consequences and being educated about online hate speech through peers or campaigns all positively predicted some direct and indirect forms of online bystander intervention.

User intervention against incivility is a significant element of democratic norm enforcement on social media, and feeling personally responsible for acting is a vital prerequisite for intervention. However, our insight into how users construe their sense of personal responsibility and expectations of other users remains limited. By theoretically foregrounding user perspective, this study investigates the boundaries and nuances of user responsibility to intervene against incivility. Empirically, it draws on 20 qualitative vignette interviews with young people in Germany. The findings show that as contexts collapse in users' newsfeeds, the imagined boundaries of personal public spheres and own social relationships with uncivil users serve as heuristics for hierarchizing and delimiting personal responsibility to intervene. Beyond abstract individual responsibility for the public discourse, practical responsibility is distributed among personal public spheres. [ABSTRACT FROM AUTHOR]

Background and Objectives: As the first three links of the chain of survival of victims of cardiac arrest depend on prompt action by bystanders, it is important to educate as much of the population as possible about basic life support and use of an automatic external defibrillator (BLS and AED). Schoolchildren are an accessible population that can be easily taught and numerous BLS and AED courses are available. The aim of this study was to assess the effectiveness of two different practical approaches to teaching BLS and AED. Material and Methods: We compared two different BLS and AED courses (course A and B) offered to 280 eighth- and ninth-grade students in primary schools. Knowledge about and the intention to perform BLS and AED were evaluated using validated questionnaires before and after the courses. Descriptive methods were used to describe the results. To compare courses, we used the Mann–Whitney U test. A p value of <0.05 was considered statistically significant. Results: Differences in knowledge and intention to perform BLS and AED after the courses were significant between courses (p < 0.001 and p = 0.037, respectively). After course A, students demonstrated significantly better knowledge and numerically greater intention to perform BLS and AED (intention score 6.55 ± 0.61 out of 7). Conclusions: Courses in which students have the opportunity to individually practice BLS skills show a greater increase in knowledge and in intention to perform BLS and AED. [ABSTRACT FROM AUTHOR]

Background: Over 30,000 people experience out-of-hospital cardiac arrest in the United Kingdom annually, with only 7–8% of patients surviving. One of the most effective methods of improving survival outcomes is bystander intervention in the form of calling the emergency services and initiating chest compressions. Additionally, the public must feel empowered to act and use this knowledge in an emergency. This study aimed to evaluate an ultra-brief CPR familiarisation video that uses empowering social priming language to frame CPR as a norm in Scotland. Methods: In a randomised control trial, participants (n = 86) were assigned to view an ultra-brief CPR video intervention or a traditional long-form CPR video intervention. Following completion of a pre-intervention questionnaire examining demographic variables and prior CPR knowledge, participants completed an emergency services-led resuscitation simulation in a portable simulation suite using a CPR manikin that measures resuscitation quality. Participants then completed questionnaires examining social identity and attitudes towards performing CPR. Results: During the simulated resuscitation, the ultra-brief intervention group's cumulative time spent performing chest compressions was significantly higher than that observed in the long-form intervention group. The long-form intervention group's average compressions per minute rate was significantly higher than the ultra-brief intervention group, however both scores fell within a clinically acceptable range. No other differences were observed in CPR quality. Regarding the social identity measures, participants in the ultra-brief condition had greater feelings of expected emergency support from other Scottish people when compared to long-form intervention participants. There were no significant group differences in attitudes towards performing CPR. Conclusions: Socially primed, ultra-brief CPR interventions hold promise as a method of equipping the public with basic resuscitation skills and empowering the viewer to intervene in an emergency. These interventions may be an effective avenue for equipping at-risk groups with resuscitation skills and for supplementing traditional resuscitation training. [ABSTRACT FROM AUTHOR]

Researchers have conducted studies on integrating autonomous artificial intelligence (AI) in Virtual Reality Training (VRT); however, little is known about the effectiveness of these trainings and the skills typically taught. Out of the 2,017 related articles found, there were 20 articles that met our inclusionary criteria. We analyzed the 20 articles along the dimensions of participant demographics (e.g. age, disability, ethnicity); skills taught; measurement methods; components of VRTs (e.g. feedback, communication medium, degree of immersion); effectiveness; and social validity. We also checked the 11 VRTs mentioned in the present review for components of behavior skills training (BST). Our results showed that VRT is effective in teaching social, safety, and professional skills (e.g. initiation of play, emergency bystander intervention, job interview) to 1,144 participants, including children with disabilities and adults with and without disabilities. Across the reviewed articles, authors probed for skill generalization and found that the targeted skills generalized across setting or time in 15 out of 20 (75%) articles. Our results indicate that VRT is a flexible and viable option for scaling BSTs, although additional research is needed for cost-benefit analysis. Lastly, we discussed ways for behavior analysts to leverage VRTs with autonomous AI and recommendations for future research. [ABSTRACT FROM AUTHOR]

Background: Group-based situations are common settings for cyberbullying, making bystander responses crucial in combating this issue. This study investigated how adolescent bystanders respond to various victims, including family members, friends, teachers, and celebrities. This study also examined how different parenting styles influenced children's cyber bystander involvement. Methods: This study employed data from a cross-sectional school survey covering 1,716 adolescents aged 13–18 years from public and vocational schools in China collected in 2022. Logistic regression analyses were conducted to measure demographic characteristics, cyberbullying experiences, and parental rearing behaviors in predicting bystander reactions. Results: The findings showed that middle school students preferred to "ask for help" while high school students tended to choose "call the police" when witnessing cyberbullying incidents. Bystanders growing up with parental rejection and overprotection, having previous cyberbullying victimization experiences, where the victims were disliked by them, exhibited fewer defensive reactions. Conclusions: This study has implications for future research and practices involving parental involvement in cyber bystander interventions, which could provide implications for future practice in designing specific intervention programs for cyberbullying bystander behavior. Future research and interventions against cyberbullying may provide individualized training including parents' positive parenting skills and parent-child interactions. [ABSTRACT FROM AUTHOR]

Harassment and abuse represent a pervasive and critical problem in sport with far-reaching consequences. Survivors' testimonials underscore the profound and enduring impact of these experiences at individual, interpersonal, organizational and community level. Many of their stories reveal painful inaction from responsible adults in the sport organization, aggravating the harm. Other contributing factors to the harm inflicted include a culture of silence, lack of knowledge and understanding of what constitutes abuse, unawareness of reporting and supporting mechanisms, and fear of potential consequences. While effective bystander interventions have been developed outside the sport context, particularly targeting students in higher education, such initiatives have yet to be extensively adapted and assessed within the sport context. To address this gap, the Safe Sport Allies Erasmus+ collaborative partnership relied on the intervention mapping approach as a guiding framework to systematically develop a bystander training program (i.e., Safe Sport Allies) to train youth sport participants and youth sport coaches to act as effective bystanders. The current paper describes the comprehensive development process and provides an overview of implementation and evaluation possibilities. Throughout the paper, it is explained how each step of the Intervention Mapping approach shaped the Safe Sport Allies bystander training program. The program development, and the developed plans for implementation and evaluation are presented, shedding light on challenges encountered. The bystander training program developed in this paper and the implementation and evaluation plans can serve as an outline to build future interventions within this critical domain of safeguarding in sport.

Many studies have examined that bullying bystander intervention refers to a positive, pro-social bystander behavior that prevents the sustained development of bullying incidents in the face of school bullying. Limited research has investigated the different roles of bystanders and the factors that influence their behavior. This study attempts to explore the association between being bullied and intervention by bystanders in adolescent school bullying, the role of moral disengagement, and the status of only children in this context. For this purpose, 2113 middle school students completed the Being Bullied Behavior Scale, Bystander Intervention Scale, and Moral Disengagement Scale. The study findings indicate that (1) being bullied positively anticipates the intervention by bystanders in school bullying; (2) further, moral disengagement plays an essential role in mediating the effects of bullying on bystander intervention, and being bullied "masks" the related positive influence on the bystander intervention through the negative mediation of moral disengagement; and (3) finally, the status of being an only child moderates the first half of this mediating effect. Based on this, this study implies that being bullied is more effective at predicting moral disengagement for only children. Consequently, the influence of being bullied on bystander intervention in school bullying is revealed in this study, which exhibits significant practical implications for improving the ecological environment of school bullying.

Research shows positive bystander intervention effectively mitigates bullying experiences. Yet, more evidence regarding bystander responses to bias‐based social exclusion (BSE) is needed in intergroup contexts, especially in the majority world and in areas of intractable conflict. This study assessed the effectiveness of skills and skills + contact‐based interventions for BSE among 148 Palestinian Citizens of Israel (Mage = 10.55) and 154 Jewish‐Israeli (Mage = 10.54) early adolescents (Girls = 52.32%) in Tel Aviv‐Yafo. Bystander responses were assessed by participants' reactions to hypothetical BSE scenarios over three time points. Repeated measures ANOVAs revealed both interventions significantly increased positive and decreased negative bystander responses, with changes maintained at the follow‐up. The opposite result pattern emerged for the control group. Findings suggest that both interventions can effectively encourage youth to publicly challenge BSE, even amidst intractable conflict.

The Bystander Intervention Model (BIM) has been validated for face-to-face emergencies and dictates that observers’ decision to intervene hinges on five sequential steps, while barriers block progress between steps. The current study is the first, to our knowledge, to apply the BIM in its entirety to cyber aggression and explore the ways that individual factors such as experiences with depression, social anxiety, and cyber aggression either as the target or the aggressor influence bystanders. In our preregistered study, emerging adults (N = 1,093) viewed pilot-tested cyber aggressive content and reported how they would engage with each of the steps and barriers of the BIM, if they were observing this content as a bystander in real life. Regarding the actions they would take, most participants chose non-intervention (36.3%) or private direct intervention (39.4%). Path analysis suggested that overall, the BIM can explain bystanders’ responses to cyber aggression. Nonetheless, there were some discrepancies with prior work on face-to-face emergencies, specifically that cyber bystander intervention does not appear to be as linear. As well, in contrast to the faceto-face applications of the BIM that prescribes barriers to affect only a single specific step, here we found some barriers were negatively linked to multiple steps. These findings elucidate ways in which cyber aggression in the online context may be similar to, as well as different from, aggression that occurs face-to-face. Implications of these findings for interventions are discussed. [ABSTRACT FROM AUTHOR]

The situational model of bystander behavior is a validated 5‐step process for understanding intervention in bullying and sexual harassment, yet the individual‐level and contextual‐level factors that facilitate the progression from one step to the next are not well understood. The purpose of the current study was to examine whether individual characteristics (social‐emotional skills, affective empathy, cognitive empathy, and personal attitudes toward bullying and sexual harassment) and contextual‐level factors (school climate and perceived peer attitudes toward bullying and sexual harassment) explained the association between subsequent steps of the bystander intervention model. A sample of 788 high school students completed several validated measures of these constructs. Structural equation modeling analysis revealed that each step significantly and positively predicted the next step, and the addition of a direct path from accepting responsibility to helping improved model fit. The mediational model indicated that individual‐level characteristics had significant direct effects on interpreting bullying and sexual harassment as problems, accepting responsibility, and helping, and indirect effects from noticing the bullying and sexual harassment to all subsequent steps except knowing. In contrast, contextual‐level effects contributed to accepting responsibility in an inverse direction. [ABSTRACT FROM AUTHOR]

Among criminologists there has been an expanded contemporary interest in measures that encourage bystander intervention in the social settings of escalating and potentially violent incidents. These broadly include partner abuse and domestic disputes, as well as confrontational social interaction and other forms of targeted harassment and violence (racist, sexist, homophobic, ableist etc.), in everyday life. This article considers the likely success or failure of seeking to foster such measures as a core strategy of violence prevention, with discussion of the author’s Sydneybased study of the understandings of violence arising from young men’s lived experience of its various forms. It particularly concentrates on the results of focus groups conducted with a mixed sample of young men (aged 16-25 years) between 2018-2020. These participants had personal engagements with violence and potential violence, that shaped their reservations and doubts about regular intervention and general male anti-violence advocacy as reasonable and achievable social practices.

Background: Disruptive behaviours are a recurrent concern in online gaming and are usually dealt with through reactive and punitive strategies. However, in health and educational settings, workplaces, and the context of interpersonal relationships, positive behaviour interventions have been implemented as well. This systematic review assessed the use of positive behaviour strategies as well as their effectiveness in a range of environments to suggest routes for transferring such interventions to (multiplayer) online gaming. Methods: We included 22 records in the review and examined (a) the targeted individuals/groups, (b) the specific disruptive behaviour problems that were addressed, (c) the nature of the positive behaviour strategy intervention, and (d) its effectiveness. Results: Findings showed that the most common interventions that have been investigated thus far are the promotion of active bystander intervention, the good behaviour game, and tootling/positive peer reporting. These sought to prevent or reduce aggressive behaviour, negative peer interaction, name-calling, cyberbullying, and hate speech. The identified interventions differed in their effectiveness; however, all demonstrated some degree of positive impact. Conclusions: Considering similarities and differences between online and offline settings, we propose that tootling and the good behaviour game are most suitable to be applied to (multiplayer) online gaming.

To decrease rates of sexual assault victimization, young people are encouraged to become involved when they see questionable sexual situations (i.e., be a prosocial bystander). Several factors can facilitate or inhibit intervention, including alcohol use. To inform bystander prevention programs that aim to address alcohol's impact on bystanders, the current study reviewed research focused on alcohol use and bystander decision making. In December 2022, the authors searched published studies from six major electronic databases. Empirical articles were deemed eligible if they examined alcohol and the bystander decision-making model within the context of sexual assault, were based in the United States or Canada, and not an intervention study; 32 studies were included in the final review. Across 32 studies published between 2015-2022, 12 assessed the proximal effects of alcohol on bystander constructs and the additional studies examined the distal effects of alcohol on bystander constructs. Alcohol use appeared to impede earlier steps of the bystander decision-making model; however, alcohol use was associated with impeding and facilitating bystander decision making at the latter half of the model. Overall, alcohol use appears to be negatively rather than positively associated with bystander constructs. Bystander intervention programs may want to move beyond the narrative of alcohol as a risk factor for sexual assault and discuss how alcohol impairs a bystanders' ability to recognize risk. More work is needed to ensure researchers assess alcohol consistently and with similar methods (number of drinks, subjective intoxication) to increase generalizability of findings to prevention programs.

In recent times, bystander intervention has become an integral part of the effort to address the high prevalence rates of sexual violence on college campuses. Bystanders put their lives at risk by preventing high-risk situations from happening. Despite their critical role, bystander intervention has not been adequately examined to understand their decision-making process. The current study examined the behaviour of bystanders from an African perspective using college student data from Ghana and Ivory Coast. Specifically, the study examined the influence of sexual consent attitudes, personality traits, sense of community, and prior experiences of sexual violence on two dimensions of bystander intervention. The results revealed that lack of behavioural control, sexual consent norms, and a sense of community influence bystanders' decision to intervene. Also, while personality traits failed to explain bystander behaviour, experience with sexual violence did. These findings offer important insights into developing effective sexual assault programmes on campus. [ABSTRACT FROM AUTHOR]

What solutions can we find in the research literature for preventing sexual violence, and what psychological theories have guided these efforts? We gather all primary prevention efforts to reduce sexual violence from 1985 to 2018 and provide a bird's-eye view of the literature. We first review predominant theoretical approaches to sexual-violence perpetration prevention by highlighting three interventions that exemplify the zeitgeist of primary prevention efforts at various points during this time period. We find a throughline in primary prevention interventions: They aim to change attitudes, beliefs, and knowledge (i.e., ideas) to reduce sexual-violence perpetration and victimization. Our meta-analysis of these studies tests the efficacy of this approach directly and finds that although many interventions are successful at changing ideas, behavior change does not follow. There is little to no relationship between changing attitudes, beliefs, and knowledge and reducing victimization or perpetration. We also observe trends over time, including a shift from targeting a reduction in perpetration to targeting an increase in bystander intervention. We conclude by highlighting promising new strategies for measuring victimization and perpetration and calling for interventions that are informed by theories of behavior change and that center sexually violent behavior as the key outcome of interest.

Researchers have utilized the Bystander Intervention Model to conceptualize bullying bystander behavior. The five-step model includes Notice the Event, Interpret the Event as an Emergency, Accept Responsibility, Know How to Act, and Decision to Intervene. The purpose of this study was to examine outcomes of an evidence-based bystander training within the context of the Bystander Intervention Model among middle school students (N = 79). We used a quasi-experimental design to examine differences in outcomes between bystanders and non-bystanders. We also assessed which of the steps were uniquely associated with posttraining defending behavior. Results indicated a significant increase in Know How to Act for both groups. In contrast, we found increases in Notice the Event, Decision to Intervene, and defending behavior among bystanders only. Finally, Notice the Event and Decision to Intervene were uniquely associated with posttraining defending behavior. We discuss implications of these findings for counselors. [ABSTRACT FROM AUTHOR]

With timely intervention from a bystander, drug overdose victims are more likely to survive. To characterize the frequency of bystander presence and identify overdose response barriers, we analyzed data from overdose fatalities occurring in Rhode Island from 2016 to 2021. Overall, about half (n=1,039; 48.7%) of all overdose deaths in Rhode Island had at least one bystander present. Among decedents who had at least one bystander who was unable to respond (n=338), top reasons of non-response were because they were spatially separated (64.8%), failed to recognize the signs of overdose (54.1%), or were unaware the victim was using drugs (40.2%). To promote bystander presence and address barriers to bystander response during an overdose, intervention strategies should include efforts that reduce solitary drug use and maximize bystander efficacy, including increasing awareness on the dangers of using drugs alone, increasing the availability of naloxone, and education on recognizing signs of overdose.

One way to support mental health among LGBTQI+ adolescents is by bystander intervention during bias-based bullying. We use an adolescent-focused socio-ecological framework to identify what characterizes an active bystander in bias-based bullying toward LGBTQI+ individuals. Using PRIMSA guidelines, seven databases yielded 6777 papers which were refined to 23 overall—11 on adolescent peer defending behavior, and 12 on school professional's (SP) defending behavior. For adolescents, friendship with victims and peers, social norms, intrapersonal attitudes, and school professional's self-efficacy were associated with active bystanding. There is a shared responsibility in school environments to defend LGBTQI+ adolescents in bullying incidents to improve long-term mental and physical health trajectories for this community.

Participants (n = 520) in a study of two on-campus peer-led sexual assault prevention programs focused on bystander intervention and risk reduction were assessed. This study focused on myth reduction, as well as self-defense self-efficacy. Demographics allowed for within-group comparisons along gender and race. Among men who attended Bro Code, Black men had significantly lower sexual assault myth adherence on many rape myths than the control group, not true of white men. Those women who attended Girls Night Out (GNO) had significantly lower sexual assault myth adherence than the control group. While greater reductions in myth adherence were seen in white women than among Black women, Black women had significantly lower overall sexual assault myth adherence (in both control and sample). As a side note, we found that women who attended GNO had lower general intimate partner violence myth acceptance in addition to lower sexual assault myth acceptance, with some variation on individual myths. Finally, those women who attended self-defense training were significantly more likely to endorse self-defense self-efficacy. Results were then explored through the lens of cultural, gender, intersectional, and community-based contexts. Future research needs and implications are discussed. [ABSTRACT FROM AUTHOR]

Does information about the way victims of gender-based violence (GBV) are treated by the police influence evaluations of government policies to combat gender-based violence? I theorize that because most citizens have incomplete information about such policies, information about procedural fairness should be given more weight when forming evaluations of the government's performance in this domain. Using original experiments embedded in public opinion surveys collected from Brazil, I find that information about procedural unfairness powerfully predicts more critical evaluations of GBV laws and the government's performance in helping victims. In addition, these critical opinions influence bystander intervention attitudes. Mediation analysis confirms that views of procedural unfairness are critical in explaining these effects. The implications of the findings for the implementation of specialized services are discussed in the results and conclusion. [ABSTRACT FROM AUTHOR]

Black women's sexual harassment is often overlooked and dismissed relative to White women's harassment. In three pre-registered experiments, we test whether this neglect extends to bystander intervention in sexual harassment. Participants observed an ostensibly live job interview between a man manager and a Black or White woman job candidate. The manager's questions were pre-programmed to grow increasingly harassing, and participants were asked to intervene if/when they found the interview inappropriate. A meta-analysis of the three studies (N = 1487), revealed that bystanders did not differ in their threshold for intervention when sexual harassment targeted the Black vs. White woman. Despite evidence for the relative neglect of Black women in responses to sexual harassment, these data suggest that bystanders may respond similarly for Black and White women. [ABSTRACT FROM AUTHOR]

Whether to intervene or not during a bullying situation influences how the interaction plays out. The researchers present a theoretical model of social dominance orientation, moral disengagement, and intervention self‐efficacy vis‐à‐vis intervention behaviors. Data were collected from 284 Israeli Hebrew speaking adolescents. Participants were recruited using a snowball sampling technique. The results of structural equation modeling reveals that moral disengagement was a mediator between the association of social dominance orientation with the pro‐bully bystander and outsider behaviors. Pro‐bully bystander and victim‐defender behaviors positively influenced the outsider behavior, and self‐efficacy was related to the victim‐defender behavior. Our results expand the understanding of the relationship between bystander intervention behaviors and motivational factors. Practitioner points: Bystander behavior influences how the interaction plays out.Bystander behavior is associated with social dominance orientation, moral disengagement, and intervention self‐efficacy.In understanding bystander behaviors of the pro‐bully bystander and the outsider, moral disengagement is mediated levels of social dominance orientation.

Understanding bystander barriers in sexual violence is an important step towards increasing knowledge on how to teach people to intervene safely. Although bystander behaviour has been widely studied especially in the US context, there is a dearth of research outside the Global North. In this study, we report results of an investigation in Guatemala, a Central American country with high levels of gender-based violence. In an online study, 1009 University students and staff completed adapted questionnaires on rape myth acceptance and bystander barriers. Correlational and regression analyses demonstrated that the rape myths 'She asked for it' and 'It wasn't rape' were important predictors of multiple barriers (i.e., Failure to notice, Failure to identify situation as high risk, Failure to take intervention responsibility, Failure to intervene due to a skills deficit and Failure to intervene due to audience inhibition). We discuss the results in the context of Guatemalan culture and society. [ABSTRACT FROM AUTHOR]

One way mammalian mothers support offspring is by intervening on their behalf when they receive conspecific aggression. Maternal intervention protects offspring and facilitates mother–offspring rank correlation in several female-philopatric species. We tested the hypothesis that maternal intervention during development similarly facilitates mother–offspring rank correlation in one of our two male-philopatric closest living relatives: bonobos, Pan paniscus , for whom male ranks have been described as matrifocal but mechanisms of status transmission are unclear. We predicted mothers would intervene at higher rates in bonobos compared to chimpanzees, Pan troglodytes , where sons earn adult ranks independently. We expected this difference would be especially pronounced for sons as they reached reproductive age (∼8 years) and when aggressors were adult males, which female bonobos, but not female chimpanzees, often dominate. However, for both sons and daughters of all ages (0.5–16 years) and against aggressors of varying age and sex, bonobo mothers in Kokolopori, DRC (N = 22 pairs, 210 conflicts) intervened less frequently than did chimpanzee mothers at Ngogo, Uganda (N = 66 pairs, 221 conflicts), doing so in 8% versus 49% of all conflicts. These differences persisted regardless of the severity of aggression offspring received and the distress they demonstrated. Our results provide no support for our hypothesis that conflict intervention facilitates mother–son rank correlation in bonobos. Nor are patterns explained by additional alternative hypotheses related to species variation in costs of retaliation, quality of female–female relationships or infanticide risk. We introduce two new hypotheses: (1) that success in aggressive competition is less important for male bonobos than for male chimpanzees and (2) proclivities for support are heightened in chimpanzees compared to bonobos because of increased ingroup protectiveness in chimpanzees. The latter hypothesis arises from our unexpected, preliminary observation that nonmother bonobo bystanders intervened less often than nonmother chimpanzee bystanders during these events. • Bonobo vs chimpanzee mothers intervened less often when offspring were aggressed. • Maternal likelihood of intervening increased with severity of inflicted aggression. • Bonobo mothers intervened less often regardless of severity of aggression. • Bonobo mothers intervened less often regardless of aggressor or offspring age or sex. • Bonobos mothers received less retaliation than chimpanzee mothers for intervening.

Background: Nightlife environments are high risk settings for sexual violence and bystander intervention programmes are being developed in response. However, more research is needed to understand nightlife-related sexual violence, and factors that influence bystander interventions. This study examined nightlife patron's experiences of sexual violence and associated factors; and relationships between attitudes towards, awareness and experience of sexual violence, and confidence to intervene. Methods: Cross-sectional on-street survey of nightlife patrons (N = 307, aged 18+) on a night out in an English city. Surveys (7.30pm-1.30am; Wednesday-Saturday) established sexual violence awareness, myth acceptance, and experience, and confidence to intervene. Participant's socio-demographics, nightlife alcohol consumption, and frequency of nightlife usage were collected. Results: 58.0% had ever experienced sexual violence whilst on a night out. In adjusted analyses, sexual violence was higher amongst females (adjusted odds ratio [AOR] 4.0; p < 0.001), and regular nightlife patrons (AOR 2.1; p < 0.05). The majority agreed that they would feel confident asking someone who has experienced sexual violence if they are okay/would like support (92.2%). In adjusted analyses, confidence to intervene was higher amongst those who agreed that sexual violence was an issue in nightlife (AOR 3.6; p < 0.05), however it reduced as sexual violence myth acceptance increased (AOR 0.5; p < 0.05). Conclusion: Sexual violence is a pertinent issue in nightlife. Programmes aiming to address nightlife-related sexual violence must address the wider social norms that promote sexual violence, and ensure patrons understand the extent and significance of the issue, to increase confidence to positively intervene.
