About the ICIQ

The International Consultation of Incontinence (ICIQ) has developed a series of international questionnaires and is striving to validate these questionnaires for the investigation lower urinary tract dysfunction, vaginal symptoms and lower bowel dysfunction in research and clinical settings.[1] Requests to use any of the developed ICIQs in research or clinical practice can be made by visiting ICIQ Contact Us. The following page presents information on the International Consultation on Incontinence Questionnaire for Urinary Incontinence.

International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form (ICIQ-UI Short Form)

Objective

This short questionnaire can be used by clinicians to screen for incontinence, to obtain a brief yet comprehensive summary of the level, impact and perceived cause of symptoms of incontinence and to facilitate patient-clinician discussions.[2]

Intended Population

Adult females and males[2]

Method of Use

A patient-reported questionnaire that can be done by the patient independently or during an assessment with a practitioner.

Time to complete: a few minutes[3]

Question Items[3]
  • Frequency of urinary incontinence
  • Amount of leakage
  • Overall impact of urinary incontinence
  • Self-diagnostic item
Scoring System

The ICIQ-UI Short form provides a score ranging from 0-21. With a higher score indicating greater severity of symptoms.[1] The "self-diagnostic" portion of the questionnaire is not given a score.[1]

Evidence

Reliability

Stability: Test-retest reliability range from good to very good (Kappa value = 0.67-0.90) for all items except “overall quality of life which was found to be moderate (Kappa value = 0.58).[2]

Internal consistency has been found to be excellent (Cronbach’s alpha coefficient = 0.95).[2] 

Validity

Content validity: Items in the ICIQ-UI Short form have been found to be easily interpreted by patients and appear to cover all important domains of incontinence with good response rates from community volunteers.[2]

Construct validity: The ICIQ-UI has been found to differentiated between males and females, with females reporting more incontinence than males (58.9% and 25.2% respectively, p < 0.001).[2]

Convergent validity: There currently is no “gold standard” questionnaire for incontinence, but agreement between responses to ICIQ-UI and Bristol Female Lower Urinary Tract Symptoms (BFLUTS)[4] as been investigated.[2] Questions on the ‘frequency’ and ‘usual amount’ of leakage ranged from moderate to strong (r=0.53-0.86), questions assessing the perceived causes of incontinence ranged from weak to moderate (r=0.29-0.55).[2] 

Sensitivity to change

A statistically significant reduction in symptoms have been found between baseline scores and scores following conservative treatment in both males and females in all items (p<0.0001) except for "overall quality of life" (females,p=0.12; males, p=0.24).[2]

A statistically significant decrease in symptoms has also been found between baseline scores and scores after surgical intervention in both females and males (p<0.0001).[2]
