Adaptation of panic-related psychopathology measures to Russian.

The study reports results of adaptation of panic-related psychopathology measures to Russian, including the Anxiety Sensitivity Index (ASI), the Agoraphobic Cognitions Questionnaire (ACQ), and the Mobility Inventory for Agoraphobia (MIA). Psychometric properties (e.g., reliability, factor structure, endorsement) and external validity of the adaptations were evaluated in a representative sample of Moscow residents (N = 390) and Ukrainian undergraduates (N = 492). The adapted ASI was generally equivalent to the original English-language version. The ACQ showed structural equivalency but did not exhibit expected specificity to panic. Finally, the MIA displayed notable structural discrepancies but had external validity comparable to the original.
