Minimum important differences for scales assessing symptom severity and quality of life in patients with fecal incontinence.

ABSTRACT:

Objectives

The objective of this study was to estimate the minimum important difference (MID) for the Fecal Incontinence Severity Index (FISI), the Colorectal-Anal Distress Inventory (CRADI) scale of the Pelvic Floor Distress Inventory, the Colorectal-Anal Impact Questionnaire (CRAIQ) scale of the Pelvic Floor Impact Questionnaire, and the Modified Manchester Health Questionnaire (MMHQ).

Patient responses were primarily anchored using a Global Impression of Change scale. The MID was defined as the difference in mean change from bas
