Eight White adults had been convicted of crimes of hate for their anti-Asian behaviors and were asked to participate in treatment as part of their probated court sentences. Part of the treatment package consisted of watching a movie designed to increase tolerance and appreciation of cultural diversity. A "Diversity Attitude Checklist" (DAC) was completed by each participant before and after watching the movie. Using the pre and post movie DAC scores below, test the researcher's hypothesis that the movie will result in an increase in tolerance and appreciation for cultural diversity attitude (raise DAC scores). High scores on the "Diversity Attitude Checklist" indicate more tolerance and appreciation.
