Inflammatory Rasch-built Overall Disability Scale (I-RODS) for patients with Guillain–Barré syndrome, chronic inflammatory demyelinating polyneuropathy and polyneuropathy with monoclonal gammopathy of undetermined significance: linguacultural ratification in Russia for patients with chronic inflammatory demyelinating polyneuropathy

Abstract

Background. Chronic inflammatory demyelinating polyneuropathy (CIDP) is the most common type of dysimmune neuropathy, and it can lead to either permanent or temporary disability in about half of patients. Objective assessment of functional impairment is essential for monitoring therapeutic outcomes and disease progression in CIDP. The Inflammatory Rasch-built Overall Disability Scale (I-RODS) is one of the most valuable tools for assessing disability in CIDP patients and can be used in both clinical research and routine practice. In this article, we present the results of the validation process for this scale in Russian individuals with CIDP.

Aim. To translate and validate the I-RODS for use in Russian patients with CIDP.

Materials and methods. The study enrolled 50 cases of CIDP, evenly distributed between the typical variant and Lewis–Sumner syndrome. We performed linguocultural adaptation of the original version of the I-RODS using a standard protocol, after which we assessed the psychometric properties of the Russian version (i.e., its sensitivity, reliability and validity).

Results. Psychometric evaluation demonstrated good reliability, sensitivity, and validity of the Russian I-RODS adaptation.

Conclusion. We validated the Russian-language adaptation of the I-RODS, which can be applied in for both clinical practice and research.
