From 2009 to present, the Weight IAT was available on the Project Implicit Belgium website (https://implicit.harvard.edu/implicit/belgium/selectatest.jsp Click on “Gewicht” to try it yourself). The Weight IAT includes one standard IAT (Fat vs. Thin; Good vs. Bad), sets of explicit measures (such as attitudes toward fat or thin people), set of demographic questions (weight, height, age, gender etc.), and debriefing questions about how respondents thought about their IAT score after the task. The study is in Dutch.
From 2009 to the end of 2017, there are 5,162 session IDs created for Weight IAT, and the overall completion rate is around 28.5%. There were 2,130 respondents who completed the standard IAT part of the task, which is 41.3% of the total respondents.
