Description
Summary:	Aim To perform a cross‐cultural adaptation and validation of the Neurogenic Bladder Symptom Score (NBSS) to Spanish in patients with neurogenic lower urinary tract dysfunction. Materials and Methods The questionnaire was culturally adapted according to international guidelines. It was applied, twice in a range of 14–28 days. Psychometric properties were tested such as content validity, construct validity, internal consistency, and test–retest reliability. Results A total of 82 patients between 18 and 78 years old (mean age of 43.9) participated in the study, and completed the first NBSS assessment; only 39 (32.19%) performed the test–retest study. The internal consistency was tested by Cronbach α with a result of 0.86 (95% CI, 0.81–0.90). The reliability was tested by interclass correlation coefficient with a result of 0.91 [0.87–0.95] (p < 0.0001). The construct validity was tested by Pearson correlation between NBSS and Qualiveen‐SF, which showed a moderate correlation with a result of 0.57 (p < 0.0001). One‐way analysis of variance with trend analysis demonstrated that patients who reported having a more severe problem with their bladder function had a higher NBSS total score (p < 0.001). Conclusion The results of this study demonstrated that the Spanish version of the NBSS has a good internal consistency and reliability, proving its applicability.
