Валидизация русскоязычной версии шкалы симптомов ПТСР
Objective. This study was aimed to adapt the Russian version of the PTSD Symptom Scale – Self-Report (PSS-SR) on a sample of healthcare workers providing medical care during the COVID-19 pandemic.
Material and method. The sample consisted of 177 healthcare workers from several medical organizations (Ekaterinburg, Russia). Participants completed the Russian versions of the PSS-SR, Impact of Event Scale (IES-R), and Depression, Anxiety, and Stress Scales-21 (DASS-21).
Results. Confirmatory factor analysis revealed a bifactor structure of the Russian version of the PSS-SR, evaluating both the posttraumatic symptomatology total score and three main groups of PTSD symptoms in accordance with the DSM-IV. The internal reliability of the measure was supported by the acceptable values of the α-Cronbach's coefficients for the re-experiencing (α = 0.81), avoidance (α = 0.78), increased arousal (α = 0.78) scales, and the PTSD total score (α = 0.90). Positive correlations between the PSS-SR, IES-R, and DASS-21 scores confirmed the convergent validity of the measure.
Conclusion. The Russian version of the PSS-SR is a reliable and valid instrument assessing the PTSD symptoms.
