Question 1

What are the three subscales of the PFDI-20?

Accepted Answer

The PFDI-20 contains three subscales: POPDI-6 (Pelvic Organ Prolapse Distress Inventory, questions 1-6) assesses prolapse symptoms, CRADI-8 (Colorectal-Anal Distress Inventory, questions 7-14) assesses bowel symptoms, and UDI-6 (Urinary Distress Inventory, questions 15-20) assesses urinary symptoms. Each subscale is scored from 0 to 100.

Question 2

How are the scores calculated?

Accepted Answer

Each subscale score is calculated by taking the mean of all answered items within that subscale and multiplying by 25. This produces a score from 0 to 100 for each subscale. The total PFDI-20 score is the sum of all three subscale scores, ranging from 0 to 300. Higher scores indicate greater symptom distress.

Question 3

What does 'No' mean for scoring?

Accepted Answer

If you select 'No' for a symptom (meaning you do not experience it), that item receives a score of 0. Only symptoms you experience and rate for bother level contribute to your subscale score.

Question 4

How often should I complete this questionnaire?

Accepted Answer

The PFDI-20 is typically completed at baseline before starting treatment and then at regular follow-up intervals (such as monthly or quarterly) to track how your symptoms change over time. Your healthcare provider will advise on the best schedule for your situation.
