The Relationships Between Self-reported Pain Intensity, Pain Interference, and Quality of Life Among Injured U.S. Service Members With and Without Low Back Pain

Abstract

Low back pain is a prevalent military and veteran health problem and individuals injured on deployment may be at particularly high risk of pain conditions. Given that increasing numbers of active duty and veteran military personnel are seeking care in community settings, it is critical that health care providers are aware of military health issues. The current study examined the prevalence of low back pain among individuals with deployment-related injuries, compared their self-reported pain intensity and interference ratings, and assessed the relationship between low back pain, self-reported pain ratings, and quality of life. Almost half of participants had low back pain diagnoses, and individuals with low back pain reported significantly higher intensity and interference due to their pain than individuals without low back pain. Finally, the relationship between low back pain and quality of life was explained by self-reported pain indices, underscoring the importance of patient-centered metrics in pain treatment.
