Abstract

Purpose: The present study aimed to translate the Targeting the individual's Aetiology of Nocturia to Guide Outcomes Questionnaire (TANGO) into the Greek language to create TANGO-Gr. A relative reliability study in prospective samples of community dwellers and rehabilitation centre residents was undertaken in order to validate the translation. In terms of nocturia severity, these groups were considered to be representative of patients at both ends of the scale, and therefore suitable validation purposes.

Patients and methods: The prospective descriptive study took place between 07 and 09/2020. Fifty residents in a rehabilitation centre and thirty-seven community dwellers were included in the study. All participants had more than one episode of nocturia per night. They were asked to complete the newly translated TANGO-Gr Questionnaire twice (test-retest procedure). TANGO-Gr includes three possible answers ("yes", "no", and "DK/NA") to facilitate increased validity. The study group evaluated the socio and demographic characteristics, the level of independence and the comprehensive frailty of all participants.

Results: Both groups satisfactorily completed questionnaire responses. The overall Cronbach's alpha coefficient was 0.753 (community-dwelling people: 0.776; rehabilitation centre residents: 0.531). A test-retest statistical analysis to determine reliability found an overall median Kappa of 0.88 (IQR: 0.79-0.94) in community dwellers and 0.91 (IQR: 0.84-1.00) in rehabilitation centre residents, thereby confirming an almost perfect respective agreement.

Conclusion: The validity of the newly translated TANGO-Gr Questionnaire was proven. It should be considered to be a reliable, self-administered screening tool suitable for clinical practice, and therefore invaluable for Greek-speaking people. The study also determined that certain environment-related variables may contribute to nocturia in rehabilitation centre populations, which is a finding which invites further study.
