Validation of an English version of the Padova quality of life instrument to assess quality of life following ileal pouch anal anastomosis.

Objective: Ileal pouch anal anastomosis (IPAA) is the procedure of choice for most patients requiring surgery for ulcerative colitis and familial adenomatous polyposis because of its perceived improvement in health-related quality of life (HRQL). The aims of this cross-sectional study were to validate an English version of the Padova Inflammatory Bowel Disease Quality of Life questionnaire (PIBDQL) in patients undergoing IPAA and to investigate the pre- and postoperative predictors of long-term HRQL.

Materials And Methods: In May 2005, the English version of the PIBDQL, Short Inflammatory Bowel Disease Questionnaire, and the SF-36 were mailed to 1,379 patients who underwent IPAA at the Mount Sinai Hospital between 1982 and 2004. The test-retest reliability, internal consistency, construct validity, and discriminative ability of the English version of the PIBDQL were assessed.

Results: Nine hundred fifty-five patients (69%) (475 female, 480 male; mean, age 43 years) returned the questionnaires. The mean PIBDQL score was 21.1 (3.4), suggesting good quality of life. Test-retest reliability [intraclass correlation coefficient (ICC) = 0.784] and internal consistency (Cronbach's alpha = 0.83) were good. Construct validity and discriminative ability of the English version of PIBDQL were adequate. Multivariate analysis revealed that women (p < 0.01) and Crohn's disease patients (p < 0.01) had significantly worse PIBDQL scores.

Conclusions: The English version PIBDQL is a reliable and valid disease-specific instrument for assessing quality of life in patients with IPAA. In this series, female gender and CD were significant predictors of worse HRQL.
