The influence of patient-centered teaching on medical students' stigmatization of the mentally ill.

Aim: Stigmatization by healthcare workers poses a challenge to providing care to the mentally ill. Bedside teaching during undergraduate medical education offers students an opportunity to directly interact with patients with a range of psychiatric disorders and thereby gather reflective experience. The present study investigates if this supervised contact with mentally ill patients during a one-week clinical course on psychosomatic medicine leads to stigma reduction in medical students. The factors influencing stigmatization were also investigated.

Method: This was a prospective, non-randomized, controlled interventional study done in the 2019/20 winter semester involving fourth-year medical students who attended a week-long practical block on psychosomatic medicine (intervention group). This group was compared to students who had attended a week-long practical block with a somatic focus during the same time period (control group). Stigmatization was measured before and immediately upon completion of the week using the MICA-4 scale. Data on age, sex, experience with the mentally ill, interest in psychiatry/psychosomatics, and sense of self-worth were also gathered prior to starting the practical block. Analysis of the sample of 143 students with a complete basic data set was carried out using mixed ANOVA, multiple linear regression and moderator analysis.

Results: In the context of clinical teaching with psychiatric patients, the stigmatization of the mentally ill among medical students decreased significantly more in the intervention group compared to the students in the control group who received instruction on somatic topics (p=.019, η²_p=.04). In addition, being female, having previous experience with the mentally ill and general interest in the subjects of psychiatry or psychosomatics at T₀ associated with lower stigma. In contrast, stigmatization was increased at the beginning of the study in males and those with low self-esteem. A moderating effect of the factors on stigma reduction was not seen.

Conclusion: Undergraduate clinical instruction that enables direct contact and reflective experiences with the mentally ill leads to a reduction in the stigmatizing attitudes held by medical students toward the mentally ill. This underscores the need to have practical clinical instruction using patients.
