“…Bowes-Sperry and O’Leary-Kelly (2005) adapted and expanded on Latané and Darley’s (1970) model to predict that intervention is also contingent upon (a) the ambiguity and severity of vicarious mistreatment, (b) other observers’ reactions to vicarious mistreatment, (c) the relationship between the victim and the perpetrator, (d) the third party’s organizational role, and (e) whether the third party and victim share a social identity. A number of the components of this model have been empirically upheld; bystanders have been found to be most likely to take action when the mistreatment event was unambiguous (Espinoza & Cunningham, 2010; Ghumman, Ryan, & Park, 2016; Ryan & Wessel, 2012), victim consequences were higher rather than lower in severity (Bowes-Sperry & Powell, 1999; Hellemans, Dal Cason, & Casini, 2017), the third party believed other bystanders would view the behavior as inappropriate (Bowes-Sperry & Powell, 1999), there was a professional rather than personal relationship between the victim and the perpetrator (Chui & Dietz, 2014), and the witness occupied a role with more responsibility to report mistreatment (Holland et al, 2016). Though studies have not supported shared social identity as a predictor of intervening (Bowes-Sperry & Powell, 1999; Ghumman et al, 2016), third parties were found to be more likely to intervene when they had a closer relationship with the victim (Coyne, Gopaul, Campbell, Pankász, Garland, & Cousans, in press; Ghumman et al, 2016; Ryan & Wessel, 2012), suggesting that interconnectedness between the victim and the third party does influence bystander intervention.…”
