Cronbach's alpha reliability estimates were reported as exceeding 0.91 on the total scale and 0.72 to 81 on three subscales in a study that examined the psychometric properties of 15 different language versions of the I-QOL in samples consisting primarily of women affected by stress, urge, and mixed UI (Bushnell et al., 2005).
In addition, the I-QOL was modified (with permission) for use with support persons of affected individuals dealing with UI.
For our hypothesis, we examined the level of perceptual agreement involving transformed scores (0 to 100 units) on the I-QOL (by affected individuals) and the SPI-QOL (by support persons) total scales, and on three sub-scales.
A frequency count of merged scores of 1, 2, and 3 on I-QOL and SPI-QOL items that participants felt were "a problem" for affected individuals are reported in Figure 2.
Three Turkish physical medicine and rehabilitation doctors proficient in English translated the I-QOL into Turkish.
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).
At baseline the mean number of leaks per day was 2.9; the mean I-QOL score was 51.3 and the mean UDI-6 score was 52.7.
The mean I-QOL and UDI-6 scores improved from baseline by 11.8 and 14.1 points, respectively.
One or more items were missing on 19% of the I-QOL scales and scores were imputed.
* CONCLUSIONS The I-QOL is a useful instrument for the investigation of incontinence-related quality of life in the community setting.
More women in the Uryx group reported an improvement of greater than 50% in I-QOL
