Translation and validation of Incontinence Impact Questionnaire Short Form in the Urdu language

The Incontinence Impact Questionnaire Short Form (IIQ-7 SF) is a self-administered questionnaire that is used to assess the impact of urinary incontinence on the quality of life in women. It is translated into different languages; however, there is currently no official Urdu version of this tool. The main purpose of this study was to translate the IIQ-7 SF into the Urdu language and to find out its validity and reliability in women with urinary incontinence.

The IIQ-7 was translated into the Urdu language by following the standardized steps. The original version was translated into Urdu by two translators and the back translation into English was done by an independent translator. A panel of experts reviewed the translations and a final version was drafted. Fifteen women with urinary incontinence were involved in the pilot study. The validity and reliability were then assessed on 70 women with urinary incontinence.

The content validity index (CVI) of each question ranged from 0.91 to 0.94. The convergent validity with UDI-6 was determined by using Spearman's correlation coefficient (r=0.90). Cronbach's α showed the internal consistency, which is 0.87. The test-retest reliability was calculated by the intra-class correlation coefficient, ICC=0.95. The scree plot showed the two components have eigen values greater than 1.

The Urdu version of the IIQ-7 has shown good validity and reliability in incontinence patients, according to the findings.
