Background And Aim:
The COVID-19 is a stigmatizing infectious disease even after healing. Until now, no COVID-19 stigma scale validated in Tunisian Arabic language among the general population is available. Developing such tools is necessary to detect COVID-19 stigma and reduce it effectively. Indeed, stigmatization of COVID-19 patients could increase the spread of this disease and its related mental health issues. We aimed at testing the validity of a translated and modified version of the 12-item HIV stigma scale among Tunisian COVID-19 patients.
Methods:
A cross-sectional study was conducted between November and December 2020 among a representative sample of COVID-19 patients in the governorate of Sousse, Tunisia, after quarantine. The 12-item HIV stigma scale was translated in Tunisian Arabic and then modified to be adapted to the Tunisian context. The preliminary modified version was administrated to the participants by pretrained medical doctors during phone calls. It consisted on 20 items covering the four stigma dimensions (personalized stigma, disclosure concerns, concerns with public attitudes, and negative self-image). The psychometric evaluation of this version included internal consistency as well as principal component analysis (PCA).
Results:
The responses of 346 COVID-19 patients were obtained. Their median age was 40 years (interquartile range: 30-54.5). Females represented 60.4% of them. The PCA resulted in a three factor solution with 14 items. This 14-item scale demonstrated good internal consistency with a global Cronbach's α of 0.91 and values of 0.94, 0.93, and 0.98 for social stigma, negative self-image, and disclosure concerns, respectively.
Conclusion:
This study provides a reliable and valid instrument for stigma measuring among Tunisian COVID-19 patients. The use of this scale would contribute in reducing the spread of this new infectious disease and its related mental health issues.
