Minimum important difference for validated instruments in women with urge incontinence
Neurourology and Urodynamics, 05/27/2011
Dyer KY et al. – The Minimum important difference (MID) in women with urge–predominant UI for the Urogenital Distress Inventory (UDI) and UDI irritative are –35 and -15. The findings are consistent with previously reported MIDs for the Overactive Bladder Questionnaire (OAB–q) subscales. Distribution–based method MIDs are lower values than anchor–based values. The MID did not typically change over the time.
