Neurogenic bladder symptom score: Polish translation, adaptation and validation of urinary disorder‐specific instrument for patients with neurogenic lower urinary tract dysfunction

Abstract

Introduction There is no comprehensive and specific questionnaire translated, adapted and validated in the Polish language for evaluating symptoms, quality of life and complications associated with the neurogenic lower urinary tract dysfunction (NLUTD). The aim of this study was to translate, culturally adapt and validate a Polish version of the Neurogenic Bladder Symptom Score (NBSS) for patients who experience NLUTD. Material and Methods Standardised guidelines and well‐established methods were used for translation and cross‐cultural adaptation of the NBSS. Adult patients with multiple sclerosis and spinal cord injury completed the NBSS, the International Consultation on Incontinence Questionnaire‐Short Form (ICIQ‐SF), the International Prostate Symptom Score (IPSS) and the SF‐Qualiveen. Responses were recorded twice within a 14‐day period. Results Two hundred seventy‐four Polish‐speaking patients with NLUTD were included in the study. Content validity was optimal. Significant relationships between NBSS (Incontinence) and ICIQ‐SF, NBSS (Storage and Voiding) and IPSS, and NBSS (Quality of Life) and SF‐Qualiveen confirmed good construct/criterion validity. An intercorrelation study revealed that internal consistency was good for the total NBSS and specific domains (Cronbach's alpha >0.7). Test‐retest reliability (reproducibility) demonstrated strong stability (intra‐class correlation coefficients >0.7 for the total NBSS). No ceiling or floor effects were present. Conclusions The Polish NBSS demonstrated good measurement properties for a large cohort of patients with NLUTD. It is a suitable tool to assess NLUTD symptoms, consequences and quality of life. The Polish NBSS will support routine clinical practice of all types of physicians in Poland who care for patients with NLUTD.

Psychometric properties of the Persian version of neurogenic bladder symptom score questionnaire: A methodological study on patients with multiple sclerosis and stroke

“…The median total score was 15 (4-51). The median for the incontinence subdomain was 1 (0-29), for storage and voiding were 11 (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18), and for the consequences subdomain, was 2 (0-12). In terms of question 24, the median score was 2 (1-4).…”

“…Taking into account linguistic and cultural differences, a window should be provided for the connection of different world centers. 7,8 From time immemorial, there have been urinary-specific quality of life (QOL) measures, such as the Qualiveen and the SCI-QOL bladder management complications tool. However, they focus mainly on the impact of bladder issues on QOL; rather than directly measuring symptom burden, 9,10 and none of these questionnaires can completely cover the NLUTD.…”

Cross‐cultural adaptation and validation of the neurogenic bladder symptom score for Spanish speakers

“…21 The NBSS has been validated previously in Portuguese, 17 Greek, 22 Russian, 23 Turkish, 24 and Polish. 25 This study reflects the effort of three Spanishspeaking countries, working together to achieve homogeneity and to prove the feasibility of the use of this questionnaire in the Spanish-speaking population. The process we followed for the cross-cultural adaptation and validation is well recognized and has been used for the validation of other documents into Spanish.…”

“…We acknowledge that there are many questionnaires that include bowel and sexual dysfunction items, nevertheless we chose the NBSS because it has been applied in many neurologic diseases such as MS, 18 SCI, 19 cerebral palsy, 15 and spina bifida, 20 and it also has proven responsiveness to positive clinical change 21 . The NBSS has been validated previously in Portuguese, 17 Greek, 22 Russian, 23 Turkish, 24 and Polish 25 …”

Population-Based Study of Prevalence, Bother and Behavior Related to Treatment for Lower Urinary Tract Symptoms and Overactive Bladder among Polish Neurogenic Patients

“…Importantly, education, counselling and increased awareness of ANLUTD can be provided not only by urologists but also by different types of clinicians. Fortunately, the importance of urology care in neurogenic patients has gained attention in Poland and other Eastern European regions [23,24]. Future health improvement programs in Poland need to definitively reach neuro-urological patients.…”
