Background. Chronic inflammatory demyelinating polyneuropathy (CIDP) is the most common immune‑mediated polyneuropathy. CIDP is characterized by a long‑term progressive or recurrent course of the disease and the development of neurological deficits and disability, it is important to assess the quality of life of patients. The paper presents the results of the first and second steps of validation of the Chronic acquired polyneuropathy – Patient Reported Index (CAP‑PRI) questionnaire designed to assess quality of life in patients with immune‑mediated polyneuropathy.Aim. To develop the Russian version of the CAP‑PRI questionnaire.Materials and methods. 85 patients with CIDP (according to EAN / PNS 2021 criteria) were enrolled. At the first step we conducted linguocultural validation according to the standard protocol. Two Russian‑speaking professional translators in the field of medicine performed direct translation of the original English‑language questionnaire, and the back translation was performed by native speakers with a medical background. At the second step the psychometric parameters were evaluated.Results. The developed Russian version of the CAP‑PRI questionnaire demonstrated a high level of reliability, validity and sensitivity.Conclusion. The Russian version of the CAP‑PRI questionnaire is recommended for clinical practice and research. In addition, the relationship between improved quality of life and the reduction of neurological deficits, disability and fatigue (as assessed by the IRODS, NIS and FSS scales) has been shown.
