Quality of life from research and clinical perspectives: an example from paediatric psycho-oncology.

In clinical oncology and research, health-related quality of life (HRQL) of patients has increasingly gained attention. Although there is agreement that HRQL is a multidimensional construct incorporating primarily the patient's evaluation of his/her life, the construct lacks a uniform model of conceptualization. This article briefly outlines definitions and methods of assessing quality of life in children and adolescents. The case report of a 10-year-old boy who underwent hematopoietic stem cell transplantation views HRQL from various perspectives. Self- and proxy assessments are compared, and the expertise of psychotherapeutic work is combined with data gathered by standardized questionnaires.
