The objective of this study was to assess the effects of health behaviors on Quality of Life QOL that are independent of the effects of health status. A sample of approximately 5,000 randomly selected Navy personnel was split into halves and analysis performed on each to establish the replicability of the findings. At step one of a multiple regression procedure, health status variables were forced into the equation next, health behavior variables were entered. As expected, the block of health status variables was significantly related to QOL self-assessed health and fitness status and lower reporting of physical symptoms accounted for 16 and 18 of the variance in QOL for the two subsamples. After controlling for health status, two behavioral measures made unique contributions to the prediction of QOL behaviors related to avoiding unnecessary risks as a driver or pedestrian and avoiding or minimizing accidents. Wellness maintenance behaviors also were associated with QOL in one subsample. After controlling for health status, health behavior measures contributed an additional 11 and 6 of the explained variance in QOL for the two subsamples. Results indicate that health behaviors influence QOL independently of health status.
