Psychosocial and demographic predictors of quality of life in a large sample of cancer patients.

In recent years, there has been increasing emphasis on understanding how the cancer experience affects individuals' quality of life (QOL). The goal of this study was to assess the QOL and to identify psychosocial predictors of QOL among a large sample of patients with a variety of cancers. Specifically, we assessed the unique contribution of demographic variables, medical variables, and social support on patients' QOL and psychological adjustment.
