Test - retest reliability of the Indonesian version of the Overactive Bladder Symptom Score (OABSS) and its correlation with standard assessment tools - Abstract

Aim:To evaluate the test-retest reliability of the Indonesian version of OABSS and its correlation with other validated assessment tools for OAB.

Methods:Eligible patients aged 18 years with established OAB were instructed to complete 3-day micturition diaries and the OABSS, International Prostate Symptom Score (IPSS) and Patient Perception of Bladder Condition (PPBC) on two separate visits: Week 0 and Week 2. Test-retest reliability was examined using the internal correlation coefficient (ICC) and weighted Kappa coefficients between first and second applications of the OABSS. Pearson or Spearman correlation coefficients were calculated to test the correlation of OABSS with IPSS, IPSS Quality of Life (QOL) item, PPBC and clinical variables of the 3-day voiding diary.

Results:ICC for the OABSS total score was 0.83. The weighted Kappa coefficients of individual scores in OABSS were 0.55-0.66. In the first and second applications of OABSS, the Pearson correlation coefficients were 0.46-0.56 and 0.36-0.53 between OABSS and three clinical variables of the 3-day voiding diary (frequencies of micturition, urgency and urge incontinence). At Visit 1, the Spearman correlation coefficients were 0.41 between OABSS and IPSS total score, 0.47 between OABSS and IPSS QOL, and 0.34 between OABSS and PPBC. At Visit 2, the Spearman correlation coefficients were 0.45 between OABSS and IPSS total score, 0.55 between OABSS and IPSS QOL, and 0.44 between OABSS and PPBC.

Conclusion: The Indonesian version of OABSS showed excellent test-retest reliability in Indonesian OAB patients. A satisfactory correlation with IPSS total and QOL scores, PPBC and several clinical variables of the 3-day voiding diary was obtained, particularly with urgency frequency.
