Objective[edit | edit source]
The Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20) is the short-form version of the Pelvic Floor Distress Inventory (PFDI).[1] Similar to the PFIQ-7, it is a health-related quality of life questionnaire for women with pelvic floor conditions to fill out.[1] The PFDI-20 is comprised of 3 scales, which include the Urinary Distress Inventory-6 (UDI-6), Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6), and the Colorectal-Anal Distress Inventory-8 (CRADI-8).[1]
Intended Population[edit | edit source]
Women over the age of 18 with disorders of the pelvic floor including urinary incontinence, pelvic organ prolapse, and fecal incontinence.[1]
Method of Use[edit | edit source]
Since it is comprised of the UDI-6, POPDI-6, and the CRADI-8, the PFDI-20 includes 20 questions. Each question begins with a "yes" or "no" response. If "yes," the patient must indicate how much the bowl, bladder, or pelvic symptoms are bothering them on a 4-point scale that ranges from "not at all" (0) to "quite a bit" (4). The sum of the 3 scales are added together to get the PFDI-20 summary score, which ranges from 0 to 300.
Evidence[edit | edit source]
Reliability[edit | edit source]
The PFDI-20 has good test-retest reliability intraclass coefficient .86, P< .001. Each of the 3 scales (Urinary Distress Inventory, Pelvic Organ Prolapse Distress Inventory, and Colorectal-Anal Distress Inventory) demonstrates significant correlation with their long-form scales (r = .86, r = .92, and r = .93, respectively, P < .0001.[1]
Validity[edit | edit source]
The PFDI-20 demonstrates construct validity as it demonstrates a significant association with appropriate measures of symptom severity and pelvic floor diagnoses.[1]
Responsiveness[edit | edit source]
Each of the 3 scales of the PFDI-20 demonstrated moderate to excellent responsiveness with effect size and standardized response mean values ranging from .70 to 1.28. The sensitivity of the PFDI-20 as a whole was excellent with an effect size of 1.48 P < .0001 and standardized response mean of 1.09 P < .0001. The ability of the PFDI-20 to discriminate between subjects who indicated that they were "worse" after surgery from those who indicated they were "better" was excellent with c-statistic of .95.[1]
Miscellaneous[edit | edit source]
The strength of the PFDI-20 is that it is a short form that gives a comprehensive assessment of the effect of pelvic floor disorders on the quality of life of women, rather than assessing just one aspect of pelvic floor function such as urinary incontinence. A more generic quality-of-life form as the SF-36 has demonstrated poor responsiveness in patients undergoing treatment for urinary incontinence. In these patient populations, it may be important to use both a generic quality-of-life instrument and a condition-specific instrument that has demonstrated responsiveness. The PFDI-20 is easy to use in both clinical and research settings.[1]
The MCID (clinically meaningful change in quality of life[2]) needs to be studied in larger populations.[1]
