Stress urinary incontinence: (Corcos et al., 2002; n = 69; Mean Age = 56.6 (11.2); Mean Duration of Incontinence = 117.5 (115.5) months)

• IIQ score of <50 indicates good quality of life
• IIQ score between 50-70 indicates moderate quality of life
• IIQ score >70 indicates poor quality of life

Where ¡°good¡± signifies a score about the population mean and ¡°poor¡± signifies a score below the population mean

Urinary incontinence: (Hagen, Hanley & Capewell, 2002; n = 237; Mean Age = 76 (12) for community sample (n=79); Mean Age = 50 (14) for clinical sample (n=75); Mean Age = 50 (12) for surgery sample (n=83); Mean Retest Time = 5 days; Scottish sample)

• Mean difference in total IIQ score = -9.7 (95% CI, -15.5 to -3.9, p=0.001)

• Kappa statistic for individual questions varied from 0.732 to 0.381

Urinary incontinence: (van der Vaart et al., 2003; n = 2043; Mean Age = 46.5 (0.3); Community sample where 79.5% report at least one positive incontinence symptom; Dutch sample)

• Excellent (Cronbach¡¯s alphas 0.83 to 0.93

Urinary incontinence: (Harvey et al., 2001; n = 155; Mean Age = 55 (11.8); Women with urinary incontinence recruited in community and through urogynecology referral)

•  Excellent (Cronbach¡¯s alpha 0.95)

Urogenital dysfunction: (van der Vaart et al., 2003; Mean Age = 46.5 (0.3) in a community sample of women (n = 2043); Mean Age = 54.7 in a clinical sample of women (n = 196) with urogenital dysfunction; Dutch sample)

• Significant concurrent validity: The clinical sample of women had significantly higher scores, indicating lower quality of life, compared with the sample of women from the community on all IIQ subscales (p<0.0001)

Urinary incontinence: (Hagen, Hanley & Capewell, 2002)

• Significant concurrent validity between total IIQ score, weight of urine leaked and subject group severity (Adjusted R² = 0.22)

• Significant predictive validity in all groups where increased number of incontinence episodes and increased weight of urine leaked separately predicted higher total IIQ score (Adjusted R²=0.22)

• Significant predictive validity in all groups where HADS anxiety predicted total IIQ score

Urinary incontinence: (Hagen, Hanley & Capewell, 2002)

• Significant convergent validity between total IIQ score and all of the expected SF-36 subscores: physical functioning (p<0.05), role-physical, general health, social functioning, and mental health (all p<0.0001)

Urogenital dysfunction: (van der Vaart et al., 2003)

• Poor to adequate convergent validity between IIQ mobility, physical, emotional, social functioning and embarrassment subscales with RAND-36 scores (r=0.14-0.45)

Urinary incontinence: (Shumaker et al., 1994; n = 162; Mean Age = 61.3 (10.2) years in a community sample of women with stress incontinence and/or detrusor instability)

• ¡°Examination of item and subscale content, and the methods used for their construction, provides reasonable assurance of face validity for the UDI and IIQ

Urinary incontinence: (Shumaker et al., 1994; n = 150 after 12 week follow-up period; Mean Age = 61.3 (10.2) years in a community sample of women with stress incontinence and/or detrusor instability. Includes women from three clinical study groups: behavioral intervention, estrogen replacement therapy, surgical treatment)

• Significant changes in all variables except pad test after 12 week follow-up period

•  Significant correlations between changes in all IIQ subscales and changes in number of episodes

Urinary incontinence: (Hagen, Hanley & Capewell, 2002)

• Mean Change in Total IIQ = -83.00 (95% CI, -100.39 to -65.58; p<0.001) from Day 1 to post-intervention
• Highly significant positive relationship between decrease in total IIQ score and decrease in total number of incontinence episode
