Incontinence Quality of Life (I-QoL) Questionnaire

Description: A disease-specific questionnaire that measures incontinence-related quality of life (QoL) in neurogenic patients [1].

Format: 22 items evaluating concerns related to incontinence, which can be divided into 3 sub-scales:

  1. avoidance and limiting behaviour
  2. psycho-social impact
  3. social embarrassment

Scoring: Items are scored on a 5-point response scale with values ranging from 1 (extremely) to 5 (not at all). Scores are then transformed to a scale score ranging from 0-100 points, with higher scores indicating higher QoL.

Administration and Burden: Self-administered. Approximately 5 minutes.   

Psychometrics: The I-QoL has been found to be a reliable, valid, and responsive measure of incontinence-related QoL in neurogenic patients. It has been shown to have high internal reliability (Cronbach’s alpha > .70 for all 4 scores; .93 for Total Score, .85 for Avoidance and Limiting Behaviour, .89 for Psycho-social Impact, and .79 for Social Embarrassment). In addition, the I-QoL had moderate significant correlations with all of the Short-Form 36 (SF-36) scores except for the “Physical Functioning” and “Bodily Pain” sub-scores.

Languages: The measure has been translated into more than 20 European, Asian, North and South American, and African languages.

QoL Concept: The I-QoL is a Health-Related QoL measure of Subjective Well-Being, which corresponds to Boxes C (achievements) and E (subjective evaluations and reactions) of Dijker’s Model.
