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

Abstract

The scoring of the 7-item Overactive Bladder Symptom Score (OABSS) questionnaire is unusual because its scale varies with the same maximum and minimum scoring values and quantifies all aspects of OAB. The questionnaire also contains a graded response for urgency. The current study is mainly concerned with the development and validation of the OABSS questionnaire for Jordanian patients. The process of translating the English OABSS questionnaire into the Arabic language involved forward and backward translations. Afterward, a prospective study was conducted to validate the Arabic version of the OABSS questionnaire by examining 235 patients from the outpatient clinics of Karak Governorate Teaching Hospital. The Arabic OABSS questionnaire was completed by all the enrolled patients before and after three months of treatment with solifenacin 5 mg taken once daily. The study included 235 regular patients (152 females and 83 males) diagnosed with OAB in accordance with the definition of the International Continence Society (ICS). The results showed major and significant differences on all seven domains of the questions on the OABSS questionnaire before and after receiving treatment (p < 0.05). Confirmatory Factor Analysis was used to measure the reliability and the questionnaire was found to be highly reliable for the construct variables. The findings derived from the current study would be beneficial for local urologists and researchers, as the Arabic version of the OABSS questionnaire was proven to be a reliable instrument for use in the assessment of OAB. Future studies are needed to compare different translated questionnaires relating to OAB.Trial registration number: NCT04309890.
