Quick-FLIC--a short questionnaire for assessing quality of life of cancer patients.
Health-related quality of life instruments tend to include a great many items. This imposes a burden on the respondents as well as undermining response rate and data quality. In this study we developed a shortened version of the Functional Living Index-Cancer (FLIC), now called Quick-FLIC, and examined its measurement properties. A questionnaire package, self-administered by 140 patients, included the FLIC and the Functional Assessment of Cancer Therapy-General. A factor analysis and clinical judgement were used to shorten the FLIC, which included 22 items. Each subscale of FLIC was shortened to include two or three items only. The Quick-FLIC included a total of only 11 items. Nevertheless, the measurement properties of the Quick-FLIC and its subscales were comparable to those of the original FLIC. It is concluded that the shortening of established health-related quality of life instruments is viable in oncology research.
