Cross-ethnic friendship self-efficacy: A new predictor of cross-ethnic friendships among children
(SAGE Publications Ltd, 2020-10-01)Across two studies (N-Study 1 = 101; N-Study 2 = 262) conducted among children in the UK, we incorporate Bandura's (1986) self-efficacy theory to intergroup contact literature and introduce the new construct of cross-ethnic ... -
Cross-ethnic friendships, psychological well-being, and academic outcomes: Study of South Asian and White children in the UK
(Psychology Press Ltd., 2017-03-04)We examined whether two interpersonal processes, self-disclosure and affirmation of ideal self, mediated the relationship between cross-ethnic friendships and psychological well-being and academic outcomes. We conducted a ... -
Cross-group friendships and outgroup attitudes among Turkish–Kurdish ethnic groups: does perceived interethnic conflict moderate the friendship-attitude link?
(Wiley, 2017-02)We investigated associations between cross-group friendships, perceived interethnic conflict, and outgroup attitudes in the context of intractable Turkish–Kurdish conflict in Turkey. Measures of cross-group friendship ... -
Cross-group friendships and psychological well-being: A dual pathway through social integration and empowerment
(Wiley, 2018-10-01)This study investigated the associations between cross-group friendships and psychological well-being among a sample of physically disabled adults. A total of 269 disabled people (M-age=39.13, SD=13.80; 114 females, 152 ... -
