Thai translation and validation of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR) and Pelvic Floor Distress Inventory (PFDI-20).

The Pelvic Organ Prolapse/Incontinence Sexual Questionnaire IUGA-Revised (PISQ-IR) and Pelvic Floor Distress Inventory (PFDI-20) are the questionnaires for evaluating sexual function and quality of life in women with Pelvic Flood Dysfunction (PFD). These two tools have been translated into many languages. The aims were to translate PISQ-IR and PFDI-20 into Thai and to assess their validity and test/re-test reliability.

Two hundred Thai women with PFD were recruited from an outpatient gynecologic clinic at King Chulalongkorn Memorial Hospital during June-December, 2017. All women completed the Thai version of PISQ-IR and PFDI-20 twice at an interval of 2 weeks and completed the Thai version of FSFI and P-QOL questionnaires at first visit for analysis of criterion validity.

For PISQ-IR, the internal consistency (Cronbach's alpha) ranged from 0.49 to 0.95 in the non-sexually active (NSA) group and 0.63 to 0.89 in the sexually active (SA) group. The test-retest reliability [intraclass correlation coefficients (ICCr)] of all subscales ranged from 0.79-0.96 in the NSA group and 0.92-0.96 in the SA group. For total PFDI-20 score, Cronbach's alpha was 0.93 and ICCr 0.83. The criterion validity (correlations of PISQ-IR subscales to FSFI) ranged from low to high correlation (r = 0.10-0.64) while the correlations of PISQ-IR subscales to PFDI-20 scores ranged from low to moderate correlation (r = 0.20-0.36).

The Thai versions of the PISQ-IR and PFDI-20 proved to have good internal consistency with strong reliability. They are valid tools for evaluating sexual function and quality of life in Thai women with PFD.
