Purpose: The purpose of this study was to identify validity the Korean version of resilience scale and identify performance status and resilience in patients with colorectal cancer. Methods: A sample of 110 patients with colorectal cancer was recruited from a hospital in Seoul. Data were analyzed using descriptive statistics, t-test, factor analysis, MAP test and Parallel test and multiple regression with the SPSS/WIN 12.0 program. Results: The reliability, validity, and factor analytic structure of the scale were evaluated. The scale demonstrated good psychometric properties and factor analysis yielded two factors. The resilience for colorectal cancer patients showed a significant difference according to marital status and performance status. The two variables were the significant factors influencing resilience, which they explained 26.5% of the variance. Conclusion: The results of the study show the importance of performance status in explaining the resilience in patients with colorectal cancer. Therefore, This study suggests that intervention programs to increase the performance status among patients could improve the resilience of cancer patients.
