Therefore, although research on this topic may have clinical implications and help inform theories regarding stigma and psychiatric illness, levels of perceived stigma have not been previously described and compared across psychiatric comorbidities among people with AUD. Due to the large possible number of psychiatric disorder combinations, questions regarding psychiatric comorbidity often require methods to create manageable and clinically meaningful subtypes of psychiatric disorders. This current study had two aims: (1) to define empirically derived profiles of psychiatric comorbidity, and (2) to describe and compare levels of perceived alcohol stigma across the empirically derived profiles of psychiatric comorbidity.
