In 4 studies, the authors investigated mediators of the effect of cross-group friendship. In Study 1, cross-group friendship among White elementary school children predicted more positive explicit outgroup attitude toward South Asians, mediated by self-disclosure and intergroup anxiety. In Study 2, cross-group friendship and extended contact among White and South Asian high school students positively predicted explicit outgroup attitude, mediated by self-disclosure and intergroup anxiety. Study 3 replicated these findings in a larger independent sample. In all 3 studies, exposure to the outgroup positively predicted implicit outgroup attitude. Study 4 further showed that self-disclosure improved explicit outgroup attitude via empathy, importance of contact, and intergroup trust. The authors discuss the theoretical and practical implications of these findings, which argue for the inclusion of self-disclosure as a key component of social interventions to reduce prejudice.
Two studies investigated intergroup contact with immigrants in Italy. In Study 1 ( N = 310 students) contact had direct positive effects on perceived out-group variability and out-group attitude, and a direct negative effect on subtle prejudice; the last two effects were mediated by intergroup anxiety. Contact also had a greater effect on reduced anxiety and improved out-group perception and evaluation when group salience was high. In Study 2 ( N = 94 hospital workers) contact at work had direct effects on out-group attitudes and rights for immigrants, and an effect on attitudes toward ethnic coworkers that was mediated by intergroup anxiety at work. The effects of contact were again moderated by group salience. These findings show that the combination of positive contact with individuals from the out-group and group salience is effective in improving intergroup relations, and often does so via reduced anxiety.
Recent evidence suggests that both direct and indirect friendship with outgroup members (knowledge of ingroup members' friendship with outgroup members) can reduce prejudice toward the outgroup. Two surveys of cross-community relationships in Northern Ireland, using a student sample (N = 341) and a representative sample of the general population (N = 735), tested whether (a) direct and indirect friendships had generalized effects on both prejudice and perceived outgroup variability and (b) reduced anxiety about future encounters with outgroup members mediated such relationships. Structural equation modeling confirmed that, in both samples, direct and indirect cross-group friendships between Catholics and Protestants were associated with reduced prejudice toward the religious outgroup and increased perceived outgroup variability, via an anxiety-reduction mechanism. It is argued that emerging generalization hypotheses help to integrate both cognition and affect and interpersonal and intergroup approaches to contact.
S. C. Wright, A. Aron, T. McLaughlin-Volpe, and S. A. Ropp (1997) proposed that the benefits associated with cross-group friendship might also stem from vicarious experiences of friendship. Extended contact was proposed to reduce prejudice by reducing intergroup anxiety, by generating perceptions of positive ingroup and outgroup norms regarding the other group, and through inclusion of the outgroup in the self. This article documents the first test of Wright et al.'s model, which used structural equation modeling among two independent samples in the context of South Asian-White relations in the United Kingdom. Supporting the model, all four variables mediated the relationship between extended contact and outgroup attitude, controlling for the effect of direct contact. A number of alternative models were ruled out, indicating that the four mediators operate concurrently rather than predicting one another.
Intergroup contact (especially cross-group friendship) is firmly established as a powerful strategy for combating group-based prejudice (Pettigrew & Tropp, 2006). Great advances have been made in understanding how contact reduces prejudice (Brown & Hewstone, 2005), highlighting the importance of affective mediators (Pettigrew & Tropp, 2008). The present study, a 3-wave longitudinal study undertaken among minority-status Colored high school children in South Africa (N = 465), explored the full mediation of the effects of cross-group friendships on positive outgroup attitudes, perceived outgroup variability, and negative action tendencies via positive (affective empathy) and negative (intergroup anxiety) affective mediators simultaneously. The target group was the majority-status White South African outgroup. As predicted, a bidirectional model described the relationship between contact, mediators, and prejudice significantly better over time than either autoregressive or unidirectional longitudinal models. However, full longitudinal mediation was only found in the direction from Time 1 contact to Time 3 prejudice (via Time 2 mediators), supporting the underlying tenet of the contact hypothesis. Specifically, cross-group friendships were positively associated with positive outgroup attitudes (via affective empathy) and perceived outgroup variability (via intergroup anxiety and affective empathy) and were negatively associated with negative action tendencies (via affective empathy). Following Pettigrew and Tropp (2008), we compared two alternative hypotheses regarding the relationship between intergroup anxiety and affective empathy over time. Time 1 intergroup anxiety was indirectly negatively associated with Time 3 affective empathy, via Time 2 cross-group friendships. We discuss the theoretical and empirical contributions of this study and make suggestions for future research.
