Quality of life of parents diagnosed with cancer: change over time and influencing factors.

Suffering from cancer while having parental responsibilities can amplify the psychosocial strain that the disease puts on the individual as well as on the whole family system. Our longitudinal study examines changes in the quality of life of cancer patients in relation to parenthood. The quality of life of cancer patients is assessed with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire 30-item version during the initial treatment period (T1) and compared to the quality of life 2 years later (T2). Two groups of patients are compared: those who have children below the age of 18 years (n= 41) and those who do not have children (n= 28). Shortly after being diagnosed with cancer (T1), both groups report a similarly low quality of life. Two years later (T2), individuals with children below the age of 18 report better quality of life on the majority of the dimensions assessed. However, variance analysis did not show that this is an independent effect of parenthood. In fact, having a partner and being female proved to impact the quality of life. These findings support the existing body of research on the influence of social support and gender on quality of life. The resulting limitations and suggestions on how to overcome them in further research are discussed.
