Abstract

Students in healthcare careers present stigma towards people with psychiatric diagnoses, so the development of interventions to reduce it is essential. This study aimed to evaluate the effectiveness of an intervention to reduce stigma towards people diagnosed with mental disorders in healthcare students in Chile.A randomized clinical trial with a before and after measurement was carried out. The intervention was part of a compulsory course and combined educational and contact strategies. A total of 244 fourth-semester students of medicine, nursing, dentistry, obstetrics, psychology, and social work participated. The intervention was effective in reducing stigmatizing attitudes and the desire for social distance. For almost all variables, the magnitude of the stigma reduction depended on the initial level of stigma, not on the profession. The intervention had positive effects on all careers. In conclusion, incorporating a stigma reduction intervention into mandatory professional training, with the active participation of the teacher in charge and experts by experience, can be a valuable tool to promote humanized and non-stigmatizing treatment.
