The purpose of the proposed project is to develop and test how well an internet-based behavioral pain self-management program, the Pain EASE program, can be used for treating low back pain in Veterans. Veterans' experiences with usability and satisfaction with the Pain EASE program will also be examined. Behavioral interventions such as exercise and cognitive behavior therapy are known to be effective for low back pain but are often not readily available or easily accessed. Veterans will be able to access the Pain EASE program via their computer with an internet connection, which will increase access to this type of treatment. Study participants will receive 10 weeks of access to the Pain EASE program, which will teach them pain coping skills to manage their low back pain. The primary outcome is pain-related functional interference.
