Intervention by members of the public during an out of hospital cardiac arrest (OHAC) including resuscitation attempts and accessible automated external defibrillator (AED) has been shown to improve survival. This study aimed to investigate the OHCA and AED knowledge and confidence, and barriers to intervention, of the public of North East England, UK. This study used a face-to-face cross-sectional survey on a public high street in Newcastle, UK. Participants were asked unprompted to explain what they would do when faced with an OHCA collapse. Chi-Square analysis was used to test the association of the independent variables sex and first aid trained on the participants\' responses. Of the 421 participants recruited to our study, 82.9% (n = 349) reported that they would know what to do during an OHCA collapse. The most frequent OHCA action mentioned was call 999 (64.1%, n = 270/421) and 58.2% (n = 245/421) of participants reported that they would commence CPR. However, only 14.3% (n = 60/421) of participants spontaneously mentioned that they would locate an AED, while only 4.5% (n = 19/421) recounted that they would apply the AED. Just over half of participants (50.8%, n = 214/421) were first aid trained, with statistically more females (57.3%, n = 126/220) than males (43.9%,  n = 87/198) being first aiders (p = 0.01 χ2 = 7.41). Most participants (80.3%, n = 338/421) knew what an AED was, and 34.7% (n = 326/421) reported that they knew how to use one, however, only 11.9% (n = 50/421) mentioned that they would actually shock a patient. Being first aid trained increased the likelihood of freely recounting actions for OHCA and AED intervention. The most common barrier to helping during an OHCA was lack of knowledge (29.9%, n = 126/421). Although most participants reported they would know what to do during an OHCA and had knowledge of an AED, low numbers of participants spontaneously mentioned specific OHCA and AED actions. Improving public knowledge would help improve the public\'s confidence of intervening during an OHCA and may improve OHCA survival.

Image-based sexual abuse (IBSA) encompasses the taking, sharing, and/or threatening to share nude or sexual images of others without their consent. The prevalence of IBSA is growing rapidly due to technological advancements, such as access to smartphones, that have made engagement in such activities easier. Bystanders offer an important means of intervention, but little is known about what facilitates or inhibits bystander action in these contexts. To address this gap in the literature, seven focus groups (n = 35) were conducted to explore the factors that facilitate and inhibit bystander action in the context of three different IBSA scenarios (taking, sharing, and making threats to share nude or sexual images without consent). Using thematic analysis, eight themes were identified, suggesting that the perceived likelihood of intervention increased with greater feelings of responsibility, empathy with the victim, reduced feelings of audience inhibition, greater feelings of safety, greater anger toward the IBSA behavior, closer relationships with the victim and perpetrator, the incident involving a female victim and male perpetrator, and perception of greater benefits of police involvement. These findings are considered alongside the physical sexual violence literature in highlighting the similarities and nuances across the different contexts. Implications for the development of policies and educational materials are discussed in relation to encouraging greater bystander intervention in IBSA contexts.

Sudden cardiac arrest, particularly out-of-hospital cardiac arrest (OHCA), is a global public health concern. However, limited research exists on the epidemiology of OHCAs occurring in public places, trends and impact of bystander intervention, and influence of extraordinary circumstances. This study investigated the epidemiological factors, bystander characteristics, and outcomes of OHCAs that occurred in public places in South Korea from 2016 to 2021 and analyzed the impact of the coronavirus disease 2019 (COVID-19) pandemic. A retrospective analysis was conducted using an Out-of-Hospital Cardiac Arrest Surveillance database, including 33,206 cases of OHCA that occurred in public places. Cases with do-not-resuscitate orders or insufficient data were excluded. A steady increase in bystander-performed cardiopulmonary resuscitation over the years and a constant decrease in bystander automated external defibrillator (AED) use were observed. Survival-to-discharge rates for OHCAs remained relatively steady until a marginal decrease was observed during the pandemic (pandemic, 13.1%; pre-pandemic, 14.4%). Factors affecting survival included the presence of a shockable rhythm, witnessed arrest, cardiac arrest due to disease, use of bystander AED, and period relative to the COVID-19 pandemic. These findings emphasize the critical role of bystanders in outcomes of OHCAs and inform public health strategies on better management of OHCAs in public places.

This qualitative study examines how youth and adult members of 4-H Shooting Sports clubs perceive firearm injury risk and risk reduction, and the applicability of a bystander intervention (BI) risk reduction framework in this community. Semistructured interviews were conducted with 11 youth and 13 adult members of 4-H Shooting Sports clubs across nine US states from March to December of 2021 until thematic saturation was reached. Deductive and inductive thematic qualitative analyses were performed. Six overarching themes emerged: (1) The tendency to view firearm injury as predominantly unintentional in nature; (2) Acknowledgment of a wide array of risks for firearm injury; (3) Perceived barriers to bystander action to prevent firearm injury including knowledge, confidence, and consequences of action; (4) Facilitators of bystander action including a sense of civic responsibility; (5) Direct and indirect strategies to address potential risks for firearm injury; and (6) Belief that BI skills training would be useful for 4-H Shooting Sports. Findings lay the groundwork for applying BI skills training as an approach to firearm injury prevention in 4-H Shooting Sports, similar to how BI has been applied to other types of injury (i.e., sexual assault). 4-H Shooting Sports club members\' sense of civic responsibility is a key facilitator. Prevention efforts should attend to the broad array of ways in which firearm injury occurs, including suicide, mass shootings, homicide, and intimate partner violence, as well as unintentional injury.

Risk for sexual violence begins early in the lifespan; thus, interventions are needed to decrease the risk for sexual violence among high school youth. The current study evaluates the Your Voice Your View (YVYV) sexual violence prevention program using a school-based cluster trial among 26 high schools in the Northeastern United States. YVYV, includes: 1) a series of four classroom workshops designed to engage students as allies in violence prevention through bystander intervention skills training, address risks for sexual aggression, and reduce risk for victimization; 2) a Lunch and Learn teacher training workshop; and 3) a 4-week social norms poster campaign based on normative data from the school. Schools were matched based on size and demographics and randomly assigned to the intervention group or a wait-list control group. A sample of 2685 10th grade students enrolled in the research and completed assessments at baseline, 2-month and 6-month follow-up periods. The magnitude of the difference in sexual aggression did not vary by condition at either follow-up period. The magnitude of 6-month differences in experiencing unwanted sexual intercourse varied significantly by condition (IRR = 0.33 [0.14-0.76]), demonstrating a small protective effect favoring intervention schools (Cohen\'s f2  = 0.012). These findings highlight the promise of multicomponent interventions grounded in bystander intervention skills training, risk reduction, and social norms theory as a promising, comprehensive approach for sexual violence prevention among youth.

Image-based sexual abuse (IBSA) represents a form of technology-facilitated sexual abuse that encompasses the taking, creating, and/or sharing (including threats to share) of nude or sexual images without consent. Unlike physical sexual violence contexts, little is known regarding if and how bystanders intervene in IBSA contexts. The current preliminary study aimed to address this gap in the literature. Specifically, seven focus groups with a sample of 35 university students (31 females, 4 males) were conducted to explore how they think they would behave (i.e., their behavioral intentions) if they were bystanders to three different IBSA scenarios: non-consensual taking, non-consensual sharing, and threatening to share nude or sexual images. Transcripts were analyzed using thematic analysis and the following themes were identified: perpetrator-centered action, victim-centered action, justice-centered action, and intervention as a well-informed and controlled process. Participants discussed how they would intervene by approaching the perpetrator, either in a confrontational or non-confrontational way, or approach the victim to inform them of what was happening, provide advice, or to support them. They also discussed involving the police. However, some group members were against these forms of intervention, particularly approaching the perpetrator and involving the police. Finally, many participants indicated that their actions need to be well-informed. These findings highlight a wide range of bystander actions in IBSA contexts that have implications for the development of policies, educational materials, and measures of bystander intervention behavior in future research.

The objective of this study is to explore the perception of teachers, parents and students\' regarding implementation of a school-based lifesaving skills program and help predict potential barriers and solutions.
This qualitative exploratory study was conducted in Karachi, Pakistan, from December 2020- to October 2021. We included students, teachers, and parents of secondary (grades VIII, IX, and X) and higher secondary level students (grades XI and XII) in Karachi, Pakistan\'s public and private schools and colleges. We selected one public, two semi-private, and two private schools. We recruited students, teachers, and parents through convenience sampling. We conducted fifteen focus group discussions (FGDs) with the students, six FGDs with the teachers, and eighteen in-depth interviews (IDIs) with parents. We transcribed the data from audio recordings and translated it into the English language. Finally, we manually analyzed the data using thematic analyses.
This study found that bystanders\' main barriers to performing lifesaving skills are lack of knowledge, fear of legal involvement, fear of hurting the patient by incorrect technique, lack of empathy among community stakeholders, and gender bias. However, the participants had a positive and supportive attitude toward implementing lifesaving skills training in schools. They suggested starting student training in the early teenage years, preferred medical staff as trainers, and suggested frequent small sessions in English/Urdu both or Urdu language and training via theory and practical hands-on drills. Furthermore, the training was proposed to be integrated into the school curriculum to make it sustainable. Finally, the government needs to support the program and make the legal environment more conducive for bystanders.
This study identified the significant barriers to performing lifesaving skills in an emergency in a low- and middle-income country (LMIC). The participants supported implementing a national lifesaving skills program in schools and colleges. However, the participants expressed that support is needed by the government for sustainability, integrating lifesaving skills into the school curriculum, providing legal support to the bystanders, and creating awareness among the general public.

Emerging adults are especially vulnerable to experiencing alcohol-related sexual assault. While bystanders play a critical role in preventing sexual assault, little is known about how bystander alcohol intoxication affects the intervention process-particularly in naturalistic settings. We recruited 315 emerging adult bargoers ages 21-29 (46% women; 28% non-college attending; 81% White) from a high-density bar area to provide responses to a sexual assault vignette and complete a breath alcohol concentration test. In this field-based study, we found a negative direct association between intoxication and appraisal of risk in the hypothetical sexual assault situation. We also found a negative indirect relation of intoxication on perceptions of personal responsibility to intervene and confidence in the ability to intervene, statistically mediated through reduced risk appraisal. Findings add to the limited literature in laboratory-based settings suggesting that bystander intoxication interferes with sexual assault intervention and help inform effective bystander intervention programming for emerging adults.

The purpose of this study was to evaluate the efficacy of the Escalation Workshop with a sample of US Navy sailors. Escalation is a one-session workshop designed to promote bystander behavior related to dating abuse. We conducted a two-arm RCT with follow-up at 4 and 8 months. Participants were 335 Navy sailors, recruited from two comparable ships based in the USA. The unit of randomization was the ship. The primary outcomes were as follows: (a) attitudes related to intervening as a bystander in dating abuse situations, (b) injunctive norms about dating abuse, (c) dating abuse-related prevention-oriented behaviors (e.g., such as posting dating violence prevention messages online), and (d) bystander behaviors including acting as a bystander to prevent peer self-harm, peer bullying, peer intoxication, or peer dating abuse, or being a proactive bystander and initiating conversations about dating abuse prevention with friends and others. Hierarchal linear models (HLMs) indicated that, compared to participants in the control group, participants in the intervention group demonstrated improvement in attitudes [β = .09, p < .001] and had more engagement than controls in prevention-oriented behavior at 8-month follow-up [β = 0.11, p < .01]. Those in the intervention group also reported larger increases than controls in bystander behavior related to peer self-harm, peer bullying, peer intoxication, and starting conversations about dating abuse. Results for dating abuse bystander behavior were mixed. At 4 months, workshop participation was marginally associated with increased bystander behavior with peers who had perpetrated dating abuse (β = 0.89, p = 0.06) and with peers experiencing physical or sexual dating abuse, or stalking or threats (β = 1.11, p = .07). However, workshop participation was not associated with increased bystander behavior with peers experiencing only physical abuse. The Escalation Workshop may be a promising strategy to promote change in dating abuse-related attitudinal change and prevention-oriented behavior, and bystander behavior with peers related to self-harm, bullying, intoxication, and some aspects of dating abuse prevention.

Engaged bystander interventions are recognized as \"promising\" programming to reduce sexual violence (SV), yet little is known of the long-term (>12-month) impact of programming on SV and related forms of gender-based violence. Funded by NIH as a prospective cohort study, Life\'s Snapshot recruited and followed three waves of high school seniors who had participated in a large high-school cluster-randomized controlled trial to evaluate the effectiveness of the Green Dot bystander intervention. This report provides the study design, recruitment methodology, recruitment and retention rates, survey items, and psychometric properties of measures included in the initial and annual electronic surveys with 24-48 months follow-up.
