The Potential Effect of the Psychiatric Clerkship and Contact-Based Hypothesis on Explicit and Implicit Stigmatizing Attitudes of Canadian Medical Students Towards Mental Illness

ObjectiveThe purpose of this study was to assess if having completed a psychiatric clerkship or having increased exposure to mental illness in general was associated with reduced explicit and implicit stigmatizing attitudes towards mental illness in undergraduate medical students.MethodsA secondary analysis of data specific to medical students from McMaster University was completed. Data were obtained through a cross-sectional survey administered electronically. It consisted of a demographic questionnaire, the Opening Minds Scale for Healthcare Providers (OMS-HC) 12-item survey, and an Implicit Association Test (IAT). The OMS-HC was used as a measure of explicit stigmatizing attitudes, whereas the IAT was used as a measure of implicit bias. All analyses were completed using Stata/IC 15 and were two-tailed with significance defined as p < 0.05.ResultsIndividuals that self-reported either having had a mental illness or diagnosis by a health care professional had significantly lower levels of explicit stigma. Final-year medical students had significantly lower levels of implicit stigmatizing attitudes than first-year medical students. Neither having completed a psychiatric clerkship nor having a close relationship with someone experiencing a mental illness was significantly associated with the explicit or implicit stigmatizing attitudes of medical students.ConclusionMore years in medical school and self-identifying or receiving a diagnosis of mental illness are associated with reduced stigmatizing attitudes, whereas having completed the psychiatric clerkship and having a close relationship with an individual experiencing mental illness were not. This study suggests that the psychiatric clerkship may have limited impact on the stigmatizing attitudes of medical students.
