To combat microaggressions and their impact on persons of color, there needs to be an increased awareness and ability to detect microaggressions when they occur. This study examined the efficacy of a multimedia intervention aimed at increasing White individuals’ ability to accurately detect microaggressions.

Undergraduate university students (61 women, 40 men, 2 other) were recruited from two predominantly White universities (PWU). All participants completed pre- and post-intervention materials, and 54 participants completed the 1-week follow-up materials. At pre-intervention, participants watched a set of video clips (e.g., television, movies), some of which contained racial and ethnic microaggressions, answered a series of questions regarding the content of the videos, and completed the Colorblind Racial Attitudes Scale (CoBRAS). Participants in the high-exposure intervention condition watched a 1-hour video lecture on racial and ethnic microaggressions. Participants in the low-exposure and control conditions read an article (e.g., racial and ethnic microaggressions or positive psychology) and answered a series of questions regarding the content of the articles. At post-intervention, completed immediately following the intervention, and 1-week follow-up, participants watched another set of video clips and some of which included racial and ethnic microaggressions. Participants then answered a series of questions regarding the content of the video, and completed a CoBRAS.

The high-exposure intervention condition did not demonstrate any significant change from pre- to post- intervention detection rates. There was no significant change from pre- to post-intervention to 1-week follow-up detection rates between conditions. Post-hoc analyses regarding colorblindness indicated a significant decrease in CoBRAS total score from pre-intervention (M = 62.23, SD = 15.39) to post-intervention across participants (M = 61.67, SD = 15.66), t(102) = 3.26, p = .002, d = .32, indicating a decrease in overall colorblindness. There was a significant decrease in Unawareness of Racial Privilege scores from pre-intervention (M = 26.67, SD = 7.51) to post-intervention across participants (M = 25.51, SD = 7.87), t(102) = 3.28, p = .001, d = .32, indicating an increased awareness of racial privilege. Awareness of institutional discrimination and blatant racial discrimination did not shift significantly. Interpretations and implications of the findings, are discussed.
