Descriptive Characteristics of the Studies Included on Caregivers’ Perspective

Authors, Year	Study Design	Participants† n, M (SD)	Type of Chronic Condition	Question Relevance	Measures of QoL	Main Results
Kizza & Muliira, 2020	Cross-sectional (quantitative design)	284, 36 (13.8)	Cancer (NS)	Family	CQoL-I-C	The key determinants of better overall caregivers’ QoL were their knowledge and self-efficacy for cancer pain management. Burden, disruptiveness, and support were the most afflicted areas damaged of caregivers’ QoL; conversely, positive adaptation and lower financial concerns enhanced their QoL.
West et al, 2012	Cross-sectional (qualitative design)	9, NE	NS	Family	Interviews	The impact of CP is extended on the entire family, resulting in physical, social, and emotional changes. Four themes were captured: family losses; life changes; emotional impact; future plans’ concerns.
Ferrell et al, 1999	Quasi-experimental (quantitative design)	231, 21–86	Different cancer syndromes: Lung, Others (NS), Breast, Prostate, Pancreatic, Colorectal, Myeloma, Liver, Bladder, Ovarian, Renal, Melanoma, Uterine/Cervical, Oesophageal	Family	QoLFT	The impact of CP is extended on the entire family, resulting in poorer scores on all caregivers’ QoL domains (social, psychological, spiritual, and physical well-being).
