Lillis, J., & Hayes, S. C. (2007). Applying acceptance, mindfulness, and values to the reduction of prejudice: A pilot study. Behavior Modification, 31(4), 389-411.
Two classroom approaches to reducing racial and ethnic prejudice among college students were compared: a class session based on acceptance and commitment therapy (ACT) and an educational lecture drawn from a textbook on the psychology of racial differences. Undergraduates who were enrolled in two separate classes on racial differences were exposed to each approach in a counterbalanced order. Results indicate that only the ACT intervention was effective in increasing positive behavioral intentions at post and a 1-week follow-up. These changes were associated with other self reported changes that fit with the ACT model. Implications of a potentially new model of prejudice are briefly discussed.
