Background: Previous research shows that Multicultural Psychology courses can produce significant improvements in students' cultural competence-related attitudes in in-person and online courses. Objective: We evaluated the impact of adding a skills-focused group assignment (i.e., Difficult Dialogues) to an online asynchronous Multicultural Psychology course. Method: Undergraduate students filled out a battery of self-report measures at the beginning and end of the course. Of the 192 total students, 107 were in course sections which completed a Difficult Dialogue (DD) group project, and 85 were in the teaching as usual (TAU) section. Results: Students in DD groups had significantly greater pre-to post-increases on social justice behavioral intentions and perceived behavioral control compared to TAU. There were no statistical differences between-groups on measures of other cultural competence constructs, though there were statistically significant within-group improvements on all outcome measures. Conclusion: Results suggest that the DD project had a particular impact on improving social justice behavioral intentions and perceived behavioral control. Teaching Implications: These shifts underscore the importance of including opportunities for students to learn and practice specific skills in Multicultural Psychology courses, and that online courses can effectively provide these opportunities.
