Allport’s four contact conditions can be reliably coded from program descriptions.

Evidence

Next, for the 134 samples with contact in the context of structured programs, we attempted to conduct more fine-grained ratings for each of Allport’s conditions. Though these research studies often implemented the conditions together, we used “yes” and “no” ratings to discern whether the program clearly and explicitly (a) focused participants on common goals, (b) emphasized a cooperative environment, (c) presented the groups with equal status, and (d) demonstrated authority sanction for the contact. Ratings of these variables by two independent judges yielded kappas between . and .97, with a median kappa of .84. — Thomas F. Pettigrew, Linda R. Tropp, A Meta-Analytic Test of Intergroup…, 91
