Jg. Cwikel et al., PSYCHOSOCIAL FACTORS THAT AFFECT THE SURVIVAL OF ADULT CANCER-PATIENTS - A REVIEW OF RESEARCH, Journal of psychosocial oncology, 15(3-4), 1997, pp. 1-34
The authors reviewed articles published from 1960 to 1996 that focused
on research on psychosocial interventions and factors that affect sur
vival from cancer. In general, they concluded that psychosocial interv
entions are most effective in the early stages of disease, the stronge
st predictors of survival are biological, the effects of psychological
factors on survival are inconsistent in early stage disease and insig
nificant in cases of metastatic cancer, sociodemographic variables (hi
gh socioeconomic status, private health insurance, and involvement in
social networks) are positively correlated with survival, and psychoso
cial factors are more apparent in patients younger than 55 years.
