Development and validation of the system of quality of life instruments for cancer patients: colorectal cancer (QLICP-CR).
OBJECTIVE
To develop and validate a quality of life (QOL) instrument for patients with colorectal cancer, QLICP-CR.


METHODS
Using the programmed decision method and the theory in instrument development, the QLICP-CR was developed and evaluated based on the data measuring QOL thrice from a sample of 110 inpatients of colorectal cancer.


RESULTS
The internal consistency α and the test-retest reliability for the overall scale and domains are above 0.70 and 0.79, respectively; the score differences between pretreatment and posttreatment have statistical significance for three domains and the overall instrument, with higher Standardized Response Mean of 0.61, 0.62, 1.33, and 0.80.


CONCLUSIONS
The QLICP-CR is of good validity, reliability, and responsiveness.
