Aims To determine whether changes in questionnaire scores on symptoms and condition‐specific quality of life reflect clinically relevant improvements in women with stress urinary incontinence (SUI). Methods We retrospectively analyzed questionnaires collected during a randomized controlled trial in women with SUI, that received pelvic floor muscle training (PFMT) in two different formats. We included 218 women that answered validated self‐assessment questionnaires at baseline and at a 4‐month follow‐up. We registered changes on two questionnaires, the International Consultation on Incontinence Modular Questionnaire–Urinary Incontinence Short Form (ICIQ‐UI SF) and the Lower Urinary Tract Symptoms Quality of Life (ICIQ‐LUTSqol). We compared these score changes to responses from the Patient Global Impression of Improvement (PGI‐I) questionnaire. Differences were analyzed with the Spearman rho and one‐way‐ANOVA. The minimum important difference (MID) was the mean change in score for women that experienced a small improvement. Results The PGI‐I correlated significantly to both the ICIQ‐UI SF (r = 0.547, P
