Article Abstract
Objective: Understanding the consequences that occur when bystanders intervene to address problematic alcohol use in others is of utmost importance because the consequences that bystanders experience can influence their behavior in future situations. Consequences are defined as the effects of attempting to help another person and may be positive and/or negative. Given the dearth of measurement scales for alcohol-related bystander intervention, the present study aimed to develop two valid and reliable measures of consequences following alcohol-related bystander intervention: one assessing positive consequences and one assessing negative consequences.
Method: Young adults ( = 1,011; 51.2% men) participated in an online survey containing bystander consequence items. A subset of participants ( = 345) completed a 2-week follow-up to evaluate test-retest reliability. Exploratory and confirmatory factor analysis and item response theory were used to examine model fit and reduce the number of items. Correlations with established measures were used to evaluate validity.
Results: One-factor solutions demonstrated the best fit for both measures. Both measures demonstrated strong internal consistency, test-retest reliability, and evidence of convergent validity.
Conclusions: The newly developed Bystanders to Alcohol Risk Scale-Positive Consequence and Bystanders to Alcohol Risk Scale-Negative Consequence are valid and reliable measures of the consequence bystanders experience when they intervene during alcohol-related situations. These measures might be used for surveillance of consequences among bystanders or as a measure of outcomes following bystander intervention training.

Addressing alcohol-involved sexual violence on college campuses: a collaborative system dynamics theory of change.

Introduction: Alcohol-involved sexual violence on college campuses is a complex public health challenge shaped by interacting individual, interpersonal, social, and institutional factors. This paper presents a systems science-based theory of change for addressing alcohol-involved sexual violence, developed through collaborative modeling with campus collaborators as part of the CAMPUS (Collaborative Model-building Project to Understand Sexual Violence) study.
Methods: This study presents a stock-and-flow diagram (SFD) theory of change developed by a research team through the synthesis of three causal loop diagrams co-produced by three cohorts of students and practitioners across five college campuses.

Sexual violence is a rampant problem on college campuses. One of the most popular ways to curb this issue in universities is bystander intervention training. Bystander intervention behavior involves identifying a problem and acting as a third party to de-escalate a situation.

Importance: While epinephrine is commonly administered in children with out-of-hospital cardiac arrest (OHCA) via an intraosseous (IO) or intravenous (IV) route, the optimal route of epinephrine delivery is unclear.
Objective: To evaluate the association between the route of epinephrine administration (IO or IV) and patient outcomes after pediatric OHCA.
Design, Setting, And Participants: Retrospective cohort study of pediatric patients (aged <18 years) with nontraumatic OHCA treated by emergency medical services who received prehospital epinephrine either via an IO or IV route.
Intraosseous route is associated with prolonged epinephrine-to-ROSC interval in out-of-hospital cardiac arrest.

Background: Prolonged resuscitation is associated with poor patient outcomes. While the importance of bystander CPR and early defibrillation is well-known, the role of other components affecting resuscitation duration is less well-established. We postulated that first-dose intraosseous (IO) epinephrine would prolong the pressor-to-ROSC interval compared to intravenous (IV) drug administration.
