Spanish validation of the social stigma scale: Community Attitudes towards Mental Illness.

Abstract Introduction The stigma against people with mental illness is very high. In Spain there are currently no tools to assess this construct. The aim of this study was to validate the Spanish version of the Community Attitudes towards Mental Illness questionnaire in an adolescent population, and determining its internal consistency and temporal stability. Another analysis by gender will be also performed. Material and methods A translation and back-translation of the Community Attitudes towards Mental Illness was performed. A total of 150 students of between 14 and 18 years old were evaluated with this tool in two stages. Internal consistency was tested using Cronbach α ; and intraclass correlation coefficient was used for test–retest reliability. Gender-stratified analyses were also performed. Results The Cronbach α was 0.861 for the first evaluation and 0.909 for the second evaluation. The values of the intraclass correlation coefficient ranged from 0.775 to 0.339 in the item by item analysis, and between 0.88 and 0.81 in the subscales. In the segmentation by gender, it was found that girls scored between 0.797 and 0.863 in the intraclass correlation coefficient, and boys scored between 0.889 and 0.774. Conclusions In conclusion, the Community Attitudes towards Mental Illness is a reliable tool for the assessment of social stigma. Although reliable results have been found for boys and girls, our results found some gender differences in the analysis.
