Abstract

Purpose

Comorbid post-traumatic stress disorder (PTSD) and depression are often associated with negative physical and mental health outcomes in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) combat veterans. The current study examines the individual contributions of these two disorders on health-related quality of life (HRQoL) in an OEF/OIF cohort. The study hypothesizes that PTSD and depression will each significantly predict lower physical and mental HRQoL even when controlling for overlapping symptoms: anhedonia, concentration, and insomnia.

Method

Participants were 220 OEF/OIF combat veterans who completed an interview and self-report questionnaires examining study variables. All study hypotheses were tested with multiple regression analyses.

Results

PTSD and depression significantly contributed to mental and physical HRQoL, even after controlling for overlapping symptoms. However, while independent main effects of PTSD and depression, with and without overlapping symptoms, emerged for predicting mental HRQoL, no significant independent main effects emerged for predicting physical HRQoL.

Conclusion

Findings suggest PTSD and depression contribute uniquely to the negative relationship with HRQoL, adding to the growing literature on distinctive and common effects of these disorders in OEF/OIF veterans. Results highlight the need to better understand the implications for assessment and treatment.
