FACT-G

Functional Assessment of Cancer Therapy - General

Constitutes the core of all subscales; can be used with patients of any tumor type.

 

Overview

The Functional Assessment of Cancer Therapy - General (FACT-G) is a 27-item questionnaire designed to measure four domains of HRQOL in cancer patients: Physical, social, emotional, and functional well-being. Original development and validation involved 854 patients with cancer and 15 oncology specialists. An initial pool of 370 overlapping items for breast, lung, and colorectal cancer was generated by open-ended interviews with patients experienced with the symptoms of cancer and oncology professionals. Using preselected criteria, items were reduced to a 38-item general version. Factor and scaling analyses of these 38 items on 545 patients with mixed cancer diagnoses resulted in the 27-item FACT-General (FACT-G). Coefficients of reliability and validity were uniformly high. The scale's ability to discriminate patients on the basis of stage of disease, performance status rating (PSR), and hospitalization status supports its sensitivity. It has also demonstrated sensitivity to change over time.
