Measures of intergroup contact

Allport's (1954) "contact hypothesis" proposed that intergroup contact is a powerful means for improving intergroup attitudes. Subsequent theory and research has developed this hypothesis into a full-blown theory that makes precise predictions about the effects of different types of contact on mainly attitudinal outcomes, and how and when those effects will occur. This chapter reviews some of the most important measures commonly used in research on intergroup contact; those specifically pertaining to intergroup contact (both direct and extended), mediating (intergroup anxiety) and moderating (membership salience) mechanisms, and outcomes (outgroup attitudes). Our aim is that the information assembled here can serve both (a) as a "toolkit" for the interested novice researcher and (b) as a useful resource to the experienced intergroup contact practitioner regarding the psychometric properties of these commonly used measures. Research on intergroup contact is of great practical and policy importance, hence it behoves us as researchers to take care to use the best possible tools for the job.
