Introduction. Pelvic organ dysfunction can significantly affect the quality of life for patients, particularly those with neurological conditions. Current questionnaires tend to evaluate pelvic organ function in isolation, making them time-consuming when seeking a comprehensive understanding. This study aimed to modify an existing Russian-language pelvic function questionnaire (QPOF) and validate its new version – QPOF-m, specifically for patients with neurological diseases.

Materials and methods. Modifications included the addition of scores ranging from 0 to 3, based on the severity of symptoms, the creation of subdomains for «storage symptoms» and «voiding symptoms», adjustments in the wording of satisfaction-related questions, and the introduction of extra questions regarding the duration of symptoms. The updated QPOF-m was validated on a sample of 102 patients (70 with Parkinson's disease (PD) and 32 with multisystem atrophy (MSA)). The validation methods employed included assessing internal consistency, content validity, and sensitivity to change through measures such as Cronbach's alpha, expert judgment, and paired t-tests for related samples.

Results. The QPOF-m questionnaire demonstrated good internal consistency (α = 0.73), solid content validity (8.6/10), and sensitivity to clinical changes in urinary and defecation symptoms. A noticeable reduction in scores following treatment confirms that the questionnaire can effectively capture clinical improvements.

Сonclusion. The QPOF-m Sakakibara – Korshunova – Suponeva Scale (SKSS) is a reliable and practical tool for diagnosing pelvic organ dysfunction, monitoring symptom progression, and tailoring therapy for patients with neurological disorders.
