Primary use / Purpose:
The Caregiver Quality of Life Index- Cancer (CQOLC) scale is a 35-item cancer-specific instrument that assesses the carer of a cancer patient’s quality of life, that is, some of the physical, social, emotional, and financial aspects of well-being, and functioning.
A panoply of instruments measuring caregiver burden have been developed since Zarit, Reever, and Bach-Peterson’s (1980) pioneering study investigating carer strain using the Zarit Burden interview. Yet, a dearth of studies exist for parsing the physical, emotional, social and financial well-being of the carer. McMillan (1996) designed a valid and reliable caregiver quality of life index to study such constructs in the partner of the patient. Later, Weitzner and colleagues (1999) modified this scale to serve as a well-being outcome measure specifically for carers of cancer patients.
The CQOLC possesses acceptable validity, test-retest reliability and internal consistency (see Weitzner, Jacobsen, Wagner, Friedland, & Cox, 1999).
