Abstract Alexithymia is a trait involving deficits in emotion processing. As an important risk factor for a wide range of psychopathologies, its assessment is important in both research and clinical practice. Originally developed in English, the Perth Alexithymia Questionnaire-Short Form (PAQ-S) is a 6-item self-report measure of alexithymia, with its brevity designed to enable alexithymia assessments in a wide range of settings. In the present research, we aimed to introduce the first Russian version of the PAQ-S and examine its psychometric properties. Our sample consisted of 203 Russian-speaking adults aged 18–74 years, recruited from the general community in Russia. The PAQ-S’s factor structure was verified with confirmatory factor analysis. Convergent and divergent validity was assessed via relationships with psychopathology symptoms and well-being. Internal consistency reliability was evaluated. The Russian version of the PAQ-S demonstrated strong factorial validity, with support for the intended 1-factor structure as an overall marker of alexithymia. The PAQ-S total scale score showed good internal consistency reliability. As expected, its convergent and divergent validity was also supported. PAQ-S scores were significant predictors of higher ill-being (anxiety, depression, and stress) and lower well-being, thus demonstrating the high clinical relevance of the alexithymia construct as measured by the PAQ-S. There were no gender differences in PAQ-S scores, and alexithymia was higher in younger people and those with less education. Overall, the Russian PAQ-S therefore demonstrated strong psychometric properties as a brief and robust measure of overall alexithymia, performing similarly to other language versions.
