Trauma can be defined as either a somatic injury or a psychological re
action in the person affected. The emotional disturbances and psychoso
cial problems of trauma patients in particular, though still measurabl
e a year or even longer after the event, have rarely been taken into a
ccount in surgical studies. Quality of life is a relevant endpoint in
multiple trauma patients, insofar as rehabilitation seems to be compli
cated by non-efficient psychological coping. With reference to the pre
requisites for a scientifically sound measuring method four instrument
s are described that seem to be suitable for measuring quality of life
in multiple trauma patients. In addition, practical advice is given f
or the design of longitudinal studies focused on quality of life in tr
auma patients.
