Prime and prejudice: The effect of priming context and prejudicial attitudes on post-traumatic stress disorder symptoms following immigrant violence

The recent arrival of immigrants into many western countries has become common. Clashes between immigrants and local residents may produce acts of violence. In two studies we assessed post-traumatic stress disorder (PTSD) symptoms in local residents exposed to immigrant violence, while addressing possible effects of priming context and prejudicial attitudes. In Study 1, context was either reminiscent/non-reminiscent of experiencing African immigrant violence (researcher with same/different ethnic origin to that of perpetrators). In Study 2, context was manipulated as a negative (“illegal-migrant”) or neutral (“working-immigrant”) framing for African immigrants. We also examined if effects of context on trauma symptoms are moderated by prejudicial attitudes towards African immigrants. As expected, higher PTSD symptom levels were evident in the presence of traumatic (Study 1) and negative (Study 2) context, yet only in residents with high prejudicial attitudes. Results suggest that both contexts and prejudice play a role in assessment of PTSD stemming from cultural conflicts. Theoretical implications of the data in terms of PTSD memory theories, are discussed including the notion of a PTSD context theory. Practical implications pertaining to the potential compatibility of researchers and therapists with trauma victims are also addressed.
