The Russian Version of Perceived Devaluation and Discrimination Scale

Background: the Perceived Devaluation and Discrimination Scale (PDDS) is an important instrument for diagnosing stigmatization in the practice of clinicians and researchers. This study was aimed to adapt the Russian version of the PDDS. Participants and Methods: a total of 1,303 volunteers completed the PDDS and the Mental Health Knowledge Questionnaire (MHKQ). Results: psychometric analysis of the adapted instrument confirms its discriminativeness, reliability and validity. Discrimination has been proven by adequate discrimination indexes. Internal reliability ensures adequate McDonald's ω coefficient (ω = 0.752). Factor validity was determined by identifying the bifactor structure of an adapted instrument. Convergent validity was confirmed by negative correlations between stigmatization and mental health knowledge. Conclusion: the Russian version of the Perceived Devaluation and Discrimination Scale (PDDS) is psychometrically justified. The prospects of psychometric analysis of the Russian version of the PDS are reduced to its validation in persons with mental disorders and modification for the diagnosis of stigmatization of patients with somatic diseases.
