This chapter focuses on the strengths and weaknesses of intergroup contact interventions designed to change children's out-group orientation. It considers a number of approaches to intergroup contact that are among the most commonly used in the field, and have been systematically evaluated in real-world settings. These approaches incorporate the principles of Allport's contact hypothesis and more recent psychological findings. Emerging perspectives in social and developmental psychology suggest possible points for considerations in the development of contact interventions. It is important to consider the extent to which intergroup contact interventions are representative of how young people experience out-groups in the real world. The majority of intergroup contact research typically examines contact between two groups, usually a majority and minority status group. In order to better reflect young people's experience of diversity, future research should develop and test contact interventions that bring together young people from a variety of groups.
