Adaptation and validation of the Scale of Self Stigma in Relatives of People with Mental Illness to the Spanish Context

Abstract: Stigma, and self-stigma in people with serious mental disorder (SMD) in particular, is one of the main problems faced by mental health professionals. However, this problem is not only found in people who suffer from this mental illness, but its consequences affect family members in the same way. For this reason, it is necessary to adapt and validate the Scale of Self-Stigma in Relatives of People with Mental Illness (SRPMI) to the Spanish context. The study involved 304 adults (M = 44.57, SD = 15.29). To assess the psychometric properties of the scale, several analyses have been carried out. The results of the confirmatory factorial analysis (CFA) have offered support to the questionnaire structure of 30 items, 10 items and the higher-order model. The structure of the models was invariant respect to gender. Cronbach's alpha values were greater than .70 in the different subscales. The results of this study have provided evidence of validity and reliability of the SRPMI, so that various mental health professionals will have an instrument to assess the degree of self-stigma that family members of people with SMI have.
