Abstract

Objective : To validate the Thai version of the Urogenital Distress Inventory(UDI) and Incontinence Impact Questionnaire (IIQ) for Thaiwomen.Materials and Methods : The UDI and IIQ have been translated into Thai. Test–retestreliability and internal consistency were tested. Two hundredand eighteen patients who visited the urogynecologic clinic atKing Chulalongkorn Memorial Hospital between March 2008and April 2010 completed the Thai version of UDI and IIQ. Ahigher score indicates a greater impairment on the quality of life(QOL) but a lower score indicates a better QOL.Results : There were 86 asymptomatic and 132 symptomatic including75 (56.8%), 11 (8.3%), and 46 (34.8%) diagnosed clinically asSUI, UUI, and MUI, respectively. There was high internalconsistency and acceptable test-retest reliability. The scoresfrom all subscales were significantly higher in symptomaticpatients. Furthermore, they were significantly higher in MUI thanSUI patients. Patients who have UUI or MUI had higher scoresin irritating symptoms subscale. In contrast, patients with SUI orMUI had higher scores in stress symptoms subscale. The IIQscores from all subscales were lower in SUI than UUI and MUIpatients. This finding shows that patients who had urgeincontinence with or without stress incontinence had worseQOL.Conclusions : The Thai version of UDI and IIQ is reliable and valid. They areuseful instruments for assessment of the severity of lower urinarytract symptoms and impact of the UI on QOL in Thai women.
