Intervention for reducing stigma: Assessing the influence of gender and knowledge

To evaluate the effectiveness in reducing social stigma of an intervention and to assess the influence of gender and knowledge. The program consisted in providing information and contact with users of mental health in order to reduce social stigma in the school environment. A total of 62 secondary school students (age 14-16 years) were evaluated with the Opinions on Mental Illness (OMI) questionnaire before and after the intervention. The subscales of the OMI were: authoritarianism, interpersonal etiology, benevolence, restrictiveness and negativism. The analysis was performed over the total sample, separating by gender and knowledge of someone with a mental disorder. t-test for repeated measures was used in the statistical analysis. All the OMI subscales showed a significant change after the intervention (P < 0.001), except for benevolence. Women presented significant changes in the subscales of authoritarianism and restrictiveness, while men presented changes in negativism and interpersonal etiology rather than restrictiveness (P < 0.001-0.003). Students that knew someone with a mental disorder presented significant changes in authoritarianism, interpersonal etiology, and negativism (P < 0.001-0.003) and students that do not know anyone with a mental disorder improved in restrictiveness and authoritarianism (P < 0.001-0.001). In all the subscales of the instrument the students improved their perception of mental disorders, reducing their levels of stigma. The intervention designed to reduce social stigma was effective, especially in the area of authoritarianism. The whole sample showed improved attitudes towards mental illness, although the areas were different depending on gender and knowledge.
