Please answer all of the questions in the following survey. These questions will ask you if you have certain bowel, bladder, or pelvic symptoms and, if you do, how much they bother you. Answer these by circling the appropriate number. While answering these questions, please consider your symptoms over the last 3 months. The PFDI-20 has 20 items and 3 scales of your symptoms. All items use a response scale from 0 to 4.
Pelvic Organ Prolapse Distress Inventory 6 (POPDI-6)
Colorectal-Anal Distress Inventory 8 (CRAD-8)
Urinary Distress Inventory 6 (UDI-6)
Scoring the PFDI-20
Obtain the mean value of all of the answered items within the corresponding scale (possible value 0 to 4) and then multiply by 25 to obtain the scale score (range 0 to 100). Missing items are dealt with by using the mean from answered items only.
PFDI-20 SUMMARY SCORE:
Add the scores from the 3 scales together to obtain the summary score (range 0 to 300).
