Measuring global bystander intervention and exploring its antecedents for helping refugees.

Although the bystander intervention model provides a useful account of how people help others, no previous study has applied it to a global emergency. This research aims to develop a scale for measuring global bystander intervention and investigate its potential antecedents in the Syrian refugee emergency. In Study 1 (N = 80) and Study 2 (N = 205), a 12‐item scale was established through a substantive‐validity assessment and a confirmatory factor analysis, respectively. Study 3 (N = 601) explored the potential antecedents of the global bystander intervention, employing British and German samples. Results show that the global bystander intervention model worked for both samples, but there were significant between‐group differences in terms of the extent to which they notice the emergency, know how to help, show political support, and donate money. Overall, the visibility of the global emergency aftermaths within the context has been deduced as a meaningful driver for between‐group differences. This research provides the first empirical evidence on global bystander intervention and it offers timely suggestions to promote support for refugees or other victims of global disasters, especially among those who are distant to the disaster zone.
