International Consultation on Incontinence Questionnaire - Short Form

Last Updated

Purpose

The ICIQ-SF is a subjective measure of severity of urinary loss and quality of life for those with urinary incontinence (UI).

 

The International Consultation on Incontinence developed an incontinence questionnaire (ICIQ) containing many long and short modules. They include ICIQ-VS for vaginal symptoms, ICIQ-OAB for overactive bladder, ICIQ-UAB for underactive bladder, ICIQ-MLUTS for male lower urinary tract symptoms (LUTS), ICIQ-FLUTS for female LUTS, ICIQ-MLUTS-SEX or ICIQ-FLUTS-SEX for LUTS gender specific sexual matters, and ICIQ-LUTSqol for LUTS related quality of life. Each short module of the ICIQ uses a similar question format and a 5-point Likert scale to assess the presence, severity and associated bother of symptoms. The earliest module to be developed and most common in usage is the International Consultation on Incontinence Modular Questionnaire – Short Form for Urinary Incontinence (ICIQ-UI Short Form). This is a 4-item subjective measure designed to assess the level, impact, and perceived cause of incontinence on quality of life in adult populations. This is the measure for which the psychometrics below are based upon.

Key Descriptions

  • The ICIQ is a self-reported survey and screening tool for incontinence.
  • 4 main items (of 6 total) ask for rating of symptoms in the past 4 weeks.
  • Take sum score of items 3, 4, 5 (items 1 and 2 are demographic) for the actual score.
  • The final item is a self diagnostic item that is un-scored.
  • Items (questions) 1 and 2 are demographic questions (DOB and gender). Item (3, 4, and 5) scores are summed for the total score on the ICIQ-UI SF
  • Scoring scale: 0-21, minimum 0, maximum 21. A higher score indicates greater impairment from incontinence.
  • Items regarding the average frequency and amount of leakage, the impact of leakage on quality of life (QOL), and the perceived cause of leakage over the past four weeks
  • Item-level scores vary but range from 0-10. Item (question) 6 (self-perceived cause) is unscored.
  • The instrument has been translated and validated into several languages. To see the availability of translations, visit https://iciq.net/translations

Professional Association Recommendation

International Consultation on Incontinence recommendation grade A (Consistent Level 1 evidence i.e. randomized controlled trials [RCTs] or systematic reviews of RCTs) (Abrams et al., 2007).

Considerations

Urinary Incontinence: (Avery et al, 2004)

  • Score is 0 - 21 with a higher score indicating greater severity
  • Ability to detect change in males and females
  • With conservative management- significant change in all symptom related questions (items 3 and 4) but not in “overall quality of life”
  • With surgical management - significant change in all questions (items 3,4 and 5)
  • The ICIQ-UI SF has been translated and validated through the evaluation of adult patients with urinary incontinence in other countries. English, Chinese, Malay, Taiwanese, Italian, Greek, and Japanese versions were reviewed.

UI in Females: (Avery et al., 2004)

  • IQ di?erentiated between males and females, with women reporting more incontinence than men (58.9%and 25.2% respectively, P < 0.001)
  • detected a lower prevalence of incontinence in the community sample than in urology clinic attendees (44.7% and 9 7.2 % respectively, P < 0.001)

demonstrated a clear association between sex and the perceived causes of incontinence in both the clinic and the community samples (P < 0.0 01)

Content Validity

Urinary Incontinence: (Abrams, Cardozo and Wein, 2012)

  • The ICIQ was developed by 24 individual committees, comprised of experts on the subject. The Third International Consultation on Incontinence provided the ICIQ a grade ‘A’ rating and indicated it should be used for the basic evaluation of a patient’s perspective of urinary incontinence.

UI in Females: (Hajebrahimi et al., 2012)

  • The weighted Kappa Index between the results of the initial questionnaire and the translated version was 0.70

Face Validity

UI in Females: (Huang et al, 2008)

  • There were missing data < 2.0% of items, indicating patients interpreted all items as relevant, which has been proposed as a measure of face validity.

UI in Females: (Avery et al., 2004)

  • Low level of missing data (mean 1.6%)

Floor/Ceiling Effects

UI in Females: (Gotoh et al., 2009)

  • Excellent: Japanese version of ICIQ-SF numbers for floor effect were reported as .8% to 4.1% and ceiling effect was reported as 7.5% to 23.1% indicating no particular floor or ceiling effects

Responsiveness

UI in Females: (Lim et al., 2017)

  • The scores for all of the ICIQ‐SF items and the total scores decreased significantly after treatment with surgery (Study 1, ?=?15) or pharmaceutical agents (Study 2, ?=?58). As expected, considerably larger improvements were noted in the scores of all of the patients who received surgery (median changes for items 1 and 2: ?3.0 and ?4.0, respectively; mean changes for item 3 and the total score: ?6.3 and ?12.1, respectively; ?<?0.05) than in those of patients who received pharmaceutical treatment (median changes for items 1 and 2: ?1.0 and ?2.0, respectively; mean changes for item 3 and the total score: ?2.3 and ?5.2, respectively; ?<?0.05).
