Quality of life of women with urinary incontinence: Cross-cultural performance of 15 language versions of the I-QOL.
Similarly, test-retest reliability showed the I-QOL to be stable over time, with ICC values all greater than the recommended 0.
It is very important that the I-QOL is used to determine the changes in patients' QOL arising from urinary incontinence and that the obtained data is used to help patients return to a normal social environment.
Table 1 shows demographic and clinical data of patients and the averages of the total scores and subscores of the Turkish-language I-QOL.
We calculated the total mean I-QOL score and ICC of all subscores of I-QOL as 0.
In our study, we concluded that the Turkish-language I-QOL is internally consistent and reliable in patients with MS.
Thirty-seven patients completed the I-QOL during their first examination.
The I-QOL contains 22 items, each with a 5-point Likert-type response scale, yielding a total score and three subscale scores (avoidance behavior, psychosocial impact, and social embarrassment).
We used the intraclass correlation coefficient (ICC) to assess item-specific test-retest reliability of the I-QOL.
Three Turkish physical medicine and rehabilitation doctors proficient in English translated the I-QOL into Turkish.
Furthermore, the I-QOL has also been shown to be a validated and reliable questionnaire in patients with neurological bladder dysfunction, including MS [7].
