OBJECTIVE: To compare the disability level of colorectal cancer survivors with and without stoma by using the Korean version of the 12-item, interview-administered World Health Organization Disability Assessment Schedule 2.0 (Korean version of WHODAS 2.0). METHODS: This is a multicenter (five tertiary university hospitals and the Korea Ostomy Association) and cross-sectional survey. Colorectal cancer survivors with and without stoma were interviewed. Survey measured disability level using the Korean version of WHODAS 2.0 and health-related quality of life using the SF-36. RESULTS: A significant difference was observed between patients with and without a stoma in two subdomains: getting around (31.1 vs. 20.3; p=0.013) and participation in society (32.3 vs. 22.2; p=0.028). After adjusting for age, gender, and time since surgery, having a stoma was associated with severe to extreme disabilities in participation (OR=2.72, p=0.045). The Korean version of WHODAS 2.0 showed satisfactory internal consistency (r=0.96) and convergent validity. CONCLUSION: Patients with stoma participated less in society than those without stoma. The Korean version of WHODAS 2.0 is a reliable and valid instrument for measuring disability in Korean colorectal cancer patients.
