The AQ is a self-report measure which allows for the subject to give lower scores to the items they think would be see as stigmatizing or discriminatory towards those with mental illness in order to make themselves look better. Because the scale is a self-report<unk>  and not a behavioral observation, the answers given may not align with actual behaviors the subject engages in. Additionally, most of the studies on the AQ have been conducted in United States populations which does not make it generalizable to those outside of the US. It has also only been validated in volunteer studies of college students and adolescent students. In order to assess whether the scale can be used in measuring stigma in other populations, more research in wider and more diverse populations is needed. Another limitation is that there is only 9 subscales of stigmatizing behaviors and stereotypes. Because there are not many questions asked in the subscales, there may be key components of that behavior that are missed. There may also be other subscales that should be included upon further research into stigma.
