Results: All elements of the Russian version measured the same parameters of the Dutch 4DSQ. Some differences were identified.
Conclusion: The analysis has confirmed the possibility of using the questionnaire in the Russian-speaking population using higher threshold values: +2 points for distress and anxiety, +4 points for somatization.
