INTRODUCTION AND HYPOTHESIS: The purpose of this study is to assess the validity and reliability of a retrospective quality-of-life (QOL) assessment. METHODS: The Incontinence Impact Questionnaire (IIQ-30) and the Short-Form Health Survey (SF-12) were self-administered pre-operatively. At 3 months post-op, the IIQ-30 and SF-12 surveys were mailed to patients to reassess their pre-operative QOL status. Pearson's correlation coefficient (r) and the intraclass correlation coefficient (ICC) were used to test the validity and reliability of the recalled IIQ and SF-12 scores. RESULTS: Recall validity was excellent for the IIQ-30 (r = 0.64) and moderate for the SF-12 (r = 0.46 (physical component summary or PCS) and 0.42 (mental component summary or MCS)). Recall reliability was moderate with the IIQ-30 (ICC = 0.62) and poor with the SF-12 (ICC = 0.44 (PCS) and 0.49 (MCS)). CONCLUSIONS: The IIQ-30 can be reliably used in a retrospective manner among women who have undergone surgery for SUI 3 months earlier.
