Psychometric Assessment of PROMIS-29 as a Measure of Recovery After Colorectal Surgery: A Prospective Cohort Study
Authors' conclusion
Despite demonstrating adequate internal consistency, PROMIS-29 has limited content validity, construct validity, and responsiveness within the first 4 weeks after colorectal surgery.
Study context
- Population
- Adults undergoing elective colorectal resection at two academic hospitals in Canada
- Participants
- 282 adults
- Outcome
- Content validity, internal consistency, construct validity and responsiveness of PROMIS-29 (PHS and MHS scores; minimal important difference 3 points)
- Follow-up
- Preoperatively and weekly until POW 4
Methodological detailspsychometric assessment, COSMIN guidelines, two academic hospitals
- Psychometric assessment
- COSMIN guidelines
- Two academic hospitals
