The relationships between posttraumatic stress disorder severity, depression severity and physical health.

This study examines the relationship among posttraumatic stress disorder severity, depression severity, and subjective and objective physical health in a sample of 200 adults with posttraumatic stress disorder. Posttraumatic stress disorder severity was correlated with subjective, but not objective, health. Similarly, depression symptoms had an indirect effect on the relationship between posttraumatic stress disorder symptom severity and three measures of subjective physical health. Finally, depression symptoms had an indirect effect on the relationship between both reexperiencing and hyperarousal symptoms and subjective physical health. This research underscores the important role that posttraumatic stress disorder, particularly reexperiencing and hyperarousal symptoms, and depression may have on perceptions of physical health.
