Validation of the Russian version of the pelvic pain and urgency/frequency patient symptom scale (C.L. Parsons, 2000) for patients with chronic recurrent uncomplicated cystitis

Abstract

BACKGROUND: Questionnaires allow to objectify and quantify the disease severity, especially at the patient’s initial visit, its impact on the patients’ quality of life, as well as the dynamics of symptoms during treatment. AIM: To validate the Russian version of the Pelvic Pain and Urgency/Frequency Patient Symptom Scale (PUF scale; C.L. Parsons, 2000) for patients with chronic recurrent uncomplicated cystitis. MATERIALS AND METHODS: The Russian version of the PUF Scale was suggested to two respondent groups aged 19 to 53 years: relatively healthy volunteers, 15 women who did not complains of urinary disorders or pain/discomfort in the bladder, and 14 patients with verified diagnosis of chronic recurrent uncomplicated cystitis. RESULTS: The resulting data demonstrate the validity of the proposed Russian version of the PUF Scale. Statistically significant differences were noted in the answers to most of the questionnaire issues between two respondent groups: conditionally healthy volunteers and patients with chronic recurrent uncomplicated cystitis. A high level of internal consistency of the questionnaire was found. Cronbach’s alpha coefficient in the main group was 0.888, in the control group — 0.819. CONCLUSIONS: The study findings proved that the Russian version of the Pelvic Pain and Urgency/Frequency Patient Symptom Scale (C.L. Parsons, 2000) is a valid tool for subjective assessment of the severity of chronic recurrent uncomplicated cystitis symptoms.
