This study adapted the IMPACT-SF (Initial Measurement of Patient-Reported Pelvic Floor Complaints Tool Short Form) to include toileting behaviours and Rome IV criteria, then content-validated the modified tool using 11 experts over three rounds and translated it into Kannada with cognitive debriefing in 30 female participants.
The modified IMPACT-SF achieved excellent content validity with a scale-level content validity index (S-CVI) of 0.92–0.97; minor wording amendments were made to the Kannada version after cognitive debriefing.
- Full psychometric validation (reliability, construct validity, responsiveness) has not yet been completed. - Study participants were exclusively female, limiting applicability to male patients with pelvic floor disorders. - Sample sizes for critical review (n=5) and cognitive debriefing (n=30) are small.
The Kannada-language modified IMPACT-SF shows strong content validity as a preliminary pelvic floor screening tool for Kannada-speaking populations, but clinicians should await full psychometric validation before using it as a primary outcome measure.
