Validating 7-items Overactive Bladder Symptom Score (OABSS) through Arabic linguistic version

A randomized controlled trial of low-frequency repeated transcranial magnetic stimulation in patients with poststroke neurogenic bladder

Urinary incontinence is a common complication in stroke survivors for whom new interventions are needed. This study investigated the therapeutic effect of low-frequency (LF) repeated transcranial magnetic stimulation (rTMS) on the contralesional primary motor cortex (M1) in patients with poststroke urinary incontinence (PSI). A total of 100 patients were randomly assigned to the rTMS group or sham-rTMS group on basis of the intervention they received. Both groups underwent five treatment sessions per week for 4 weeks. Data from the urodynamic examination were used as the primary outcome. The secondary outcome measures were questionnaires and pelvic floor surface electromyography. After 4 weeks of intervention, the maximum cystometric capacity (MCC), maximum detrusor pressure (Pdet.max), residual urine output, overactive bladder score (OABSS) (including frequency, urgency, and urgency urinary incontinence), and the ICIQ-UI SF improved significantly in the rTMS group compared with those in the sham-rTMS group (P < 0.05). However, no changes in pelvic floor muscle EMG were detected in patients with PSI (both P > 0.05). Our data confirmed that 4 weeks of LF-rTMS stimulation on the contralateral M1 positively affects poststroke urinary incontinence in several aspects, such as frequency, urgency urinary incontinence, MCC, end-filling Pdet, OABSS, and ICIQ-UI SF scores.

Psychometric Properties and Cutoff Value of the Turkish Overactive Bladder Symptom Score

IMPORTANCE

The Overactive Bladder Symptom Score (OABSS) measures all overactive bladder (OAB) symptoms with graded answers, evaluates urgency symptoms, and reveals the subjective bladder control. However, the Turkish version and the cutoff value of the questionnaire have not yet been studied.

OBJECTIVE

The aims of this study were to determine the psychometric properties of the 7-item OABSS and to estimate the cutoff value of the scale.

STUDY DESIGN

This was an observational study. The internal consistency (Cronbach α) and test-retest reliability were analyzed, and exploratory factor analysis was performed. For the criterion validity, the correlations between the OABSS, the Overactive Bladder Questionnaire, the Bristol Female Lower Urinary Tract Symptoms questionnaire, and outcomes of a bladder diary were used. The cutoff value of the OABSS was analyzed by the receiver operating characteristics curve analysis.

RESULTS

Participants with (n = 49) and without (n = 38) OAB were included. The internal consistency was very strong (Cronbach α = 0.95). The test-retest reliability was very strong (intraclass correlation coefficients = 0.93-0.95, P = 0.001). The percentage of explanation of the total variance was calculated as 78%. There was a strong to very strong correlation between the OABSS and the Overactive Bladder Questionnaire and Bristol Female Lower Urinary Tract Symptoms scores and outcomes of the bladder diary. The cutoff value for the OABSS was determined as 10.5.

CONCLUSIONS

The Turkish OABSS was found to be a valid and reliable scale to determine OAB symptoms and severity. Those who score more than 10.5 on the questionnaire can be considered as at risk of OAB syndrome.

Clinical tools for evaluating the severity of overactive bladder: A systematic review of psychometric properties

OBJECTIVES

To systematically evaluate the evidence describing the psychometric properties of clinical measures for assessing overactive bladder symptoms (urinary urgency with or without urge urinary incontinence, urinary frequency and nocturia). To evaluate the quality of this evidence-base using the COnsensus-based Standards for selecting health status Measurement INstruments (COSMIN) checklist and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tools.

DATA SOURCES

Five electronic databases (CINAHL, EMBASE, MEDLINE, Scopus and Web of Science) were searched from dataset inception to August 2023.

REVIEW METHODS

Study screening, data extraction and quality appraisal were performed by two independent authors. Inclusion criteria were studies testing one or more psychometric properties of clinical tools for the assessment of overactive bladder symptoms among adults aged 18 years and older for both sexes. The methodological quality and quality of the evidence were evaluated using the COSMIN checklist and GRADE tools, respectively.

RESULTS

The search identified 40 studies totalling 10,634 participants evaluating the psychometric properties of 15 clinical tools. The COSMIN methodological quality was rated good for most measures, and the GRADE quality of evidence ranged from low (13%) to high (33%). The Overactive Bladder Symptom Score, Overactive Bladder Questionnaire and Neurogenic Bladder Symptom Score were of good methodological and high-GRADE evidence qualities.

CONCLUSION

Overactive Bladder Symptom Score, the Overactive Bladder Questionnaire and the Neurogenic Bladder Symptoms Score are promising psychometrically sound measures. The Overactive Bladder Symptom Score has been applied to the most culturally diverse populations supported by studies of good methodological and high-GRADE evidence quality.

Overactive bladder symptom score – translation and linguistic validation in Bengali

Aims:

Overactive bladder symptom score (OABSS) in English consists of four questionnaires. We proposed to make Bengali version and linguistic validation.

Settings:

Online survey.

Materials and Methods:

The translation and linguistic validation was done in the following manner: forward Bengali translation, backward English translation, preparation of online version, online survey, cognitive debriefing and preparation of final version. Backward translation was done by a person proficient in Bengali and English who had never seen the English version.

Results:

Forward Bengali translation from the English version of OABSS was made. Next backward translation was done. Question number 1 and 2 backward translation was in congruent at the first attempt. But question number 3 and 4 backward translation needed multiple time correction to come to congruence. After agreement of corrected version an online version was created. In the online version along with particulars of the participants, exclusion criteria, OAB diagnostic criteria, category of OAB depending on OABSS score were added. Then this online version was sent for online survey to Bengali-speaking persons (https://forms.gle/qEo8GuXSgxyULoaX9). Fifty-nine persons (43 male, 16 female) participated. Participants were from all-over India, covering many types of occupation. Overall prevalence of OAB was 15.5% and among male 6.9% and female 8.6%. No participants had any difficulty in understanding the questionnaires in congruence; only two persons were unable to understand the category of OAB as per OABSS.

Conclusion:

OABSS Bengali version is well understood in congruence and linguistically validated. Further studies would assess the reproducibility and accuracy of the questionnaire in Bengali populations.
