Objective. To psychometrically evaluate the Swedish translations of the short forms of the Pelvic Floor Impact Questionnaire (PFIQ‐7), Pelvic Floor Distress Inventory (PFDI‐20) and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ‐12). Design and Setting. Cross‐sectional design, University hospital. Sample. Forty‐four patients awaiting prolapse surgery. Methods. The dual‐panel translation method followed by an evaluation of validity and reliability in prolapse patients. Main Outcome Measures. Construct, convergent and discriminant validity, reliability via test–retest and internal consistency. Results. Item response rates were high (range 95.5–100%) for PFIQ‐7 and PFDI‐20. The corrected item–total correlations showed acceptable construct validity for PFIQ‐7 ( r =0.338–0.826) but low for PFDI‐20 ( r =0.116–0.581) and PISQ‐12 ( r =0.024–0.735). Acceptable convergent validity was found in all three instruments, with a negative correlation with the SF‐12. There were no floor or ceiling effects in the three instruments. In the test–retest analysis, intraclass correlation coefficients were significant ( r =0.888–0.943). Cronbach's α varied between 0.57 and 0.94. Conclusion. This is the first validated translation of the PFIQ‐7, PFDI‐20 and PISQ‐12 in Swedish. All three instruments indicated acceptable psychometric properties.
