Special attention needs to be paid to the attitudes of psychiatry residents toward individuals diagnosed with substance use disorders. The attitudes of trainees may be worse toward these individuals than toward individuals with other diagnoses, and these attitudes may worsen over time. While psychiatry residencies are increasingly teaching residents about how to diagnosis and treat individuals diagnosed with substance use disorders, more attention needs to be paid to educating residents about common attitudes toward these individuals. We recommend that psychiatry residency programs start with basic educational didactics and reflection exercises on attitudes toward individuals diagnosed with substance use disorders and that programs try to form a positive "hidden curriculum" in their institutions.
