Background : Lower Urinary Tract Symptoms (LUTS) affect a person’s quality of life significantly and are highly prevalent in aging male. However,
appropriate tools for evaluating their severity and progression are lacking. There has been no tool to appropriately and sufficiently evaluate and
validate their severity and progression.
Objective : To evaluate the validity and reliability of the Thai version of International Consultation on Incontinence Questionnaire-male lower urinary tract symptoms-long form (ICIQ-MLUTS-LF) questionnaire.
Materials and Methods : Questionnaire translation and validation were conducted according to the ICIQ website protocol. Content validity, internal consistency, and stability were assessed.
Results : Sixty-three men were included in the present study. The mean age of the participants was 68, with a range from 44 to 96 years. For reliability, Cronbach’s alpha value was 0.954 and considered to have internal consistency. For test-retest reliability, the questionnaires were again filled by all participants two to four weeks later. The intraclass correlation was 0.974, demonstrating stability. Nocturia was the most prevalent symptom (98%). Urinary frequency was the most bothersome symptom.
Conclusion : The Thai version of ICIQ-MLUTS-LF is a valid and reliable tool for clinical application and research
