Out-group threats and distress as antecedents of common in-group identity among majority and minority group members in the aftermath of a natural disaster.

The aim of the present study was to examine the role of out-group threats in fostering one-group perceptions directly and indirectly via post-traumatic stress symptoms in the aftermath of a natural disaster. We also tested whether these relationships differ depending on the ethnic group of belonging (majority vs. minority). Participants were 589 Italians and 122 immigrants from a region strongly affected by the earthquakes that struck Northern Italy in 2012. Results revealed that among Italians threat stemming from negative out-group behaviour was associated positively with post-traumatic stress symptoms and negatively with perceptions of being a common group with immigrant survivors. Among immigrants, threat posed by the out-group for economic resources was positively associated with post-traumatic stress symptoms and, indirectly, with higher one-group perceptions.

Feeling like a group after a natural disaster: Common ingroup identity and relations with outgroup victims among majority and minority young children.

We conducted a field study to test whether the common ingroup identity model (Gaertner & Dovidio, 2000, reducing intergroup bias: The common ingroup identity model. Philadelphia, PA: Psychology Press) could be a useful tool to improve intergroup relations in the aftermath of a natural disaster. Participants were majority (Italian) and minority (immigrant) elementary school children (N = 517) living in the area struck by powerful earthquakes in May 2012. Results revealed that, among majority children, the perceived external threat represented by the earthquake was associated with greater perceptions of belonging to a common ingroup including both ingroup and outgroup. In turn, heightened one-group perceptions were associated with greater willingness to meet and help outgroup victims, both directly and indirectly via more positive outgroup attitudes. Among immigrant children, perceived disaster threat was not associated with any of the dependent variables; one-group perceptions were positively associated with outgroup attitudes, helping and contact intentions towards outgroup victims. Thus, one-group perceptions after a natural disaster may promote more positive and supporting relations between the majority and the minority group. We discuss the theoretical and practical implications of the findings.
