Background and Objectives: Chronic functional constipation is a prevalent and symptom-based disorder of the gastrointestinal tract. Constipation takes several different forms among patients. The Wexner Constipation Scoring System (WCSS) was developed to present a uniform tool for the assessment of chronic functional constipation. The purpose of this study was to provide the Persian version of WCSS and assess its validity and reliability.
Methods: WCSS was translated into Farsi. After being linguistically validated, the Persian version of the WCSS was administered to a sample of 76 patients with chronic functional constipation. Reliability tests were used to evaluate the internal consistency (the Cronbach alpha) and reproducibility (Intraclass Coefficient Correlation [ICC]) of the tool. The validation studies were conducted to assess the convergent validity (Correlated with the Patient Assessment of Constipation Symptom [PAC-SYM]) and Concurrent Validity (Correlated with Patient Assessment of Constipation Quality of Life [PAC-QOL]) of the tool, too.
Results: The Cronbach alpha for total scores was 0.66 and the ICC was 0.85 (0.77-0.90, 95% CI). The total score of WCSS was significantly correlated with the total scores of PAC-SYM (r=0.67) and PAC-QOL (r=0.61).
Conclusion: The linguistic and psychometric evaluation demonstrated good validity and reproducibility of the Persian version of WCSS.
