Abstract:
The aim of this study was to validate the translation of the Overactive Bladder (OAB) Screener
(OAB V8) to the Malay language. It was to assess the reliability of the screener in the context of a
Malaysian population. The original screener consists of eight symptoms indicative of OAB that has
been proven to be highly sensitive and reliable. Translation was done with a modification of the
Brislin Method using back translation and a panel of experts as a final review panel. The pilot study
had two groups; a symptomatic (n=19 patients) and an asymptomatic group (n=18 patients). All
patients performed the test twice at two week intervals once at the clinic and subsequently at
home. Test-retest method was used for reliability and Cronbach’s alpha for internal consistency.
The translated questionnaire demonstrated good internal consistency in both groups of patients
for all eight items individually and for the total score. Cronbach’s alphas ranged from 0.972 to
0.981 for the symptomatic group and from 0.750 to 0.976 for the asymptomatic group. Testretest
correlation for all items was highly significant. Intraclass correlation (ICC) was high for both
the asymptomatic (ICC ranging from 0.600 to 0.953) and the symptomatic group (ranging from
0.944 to 0.989).The Malay OAB V8 showed itself to be suitable for use, reliable in distinguishing
symptomatic and asymptomatic patients and a valid instrument.
