The goal of this project is to address psychological impairment in patients seeking conservative care for musculoskeletal pain by improving physicians’ awareness of patients’ anxiety and depression symptoms, offering patients access to an affordable, confidential, smartphone app that teaches research-based techniques to improve mental resiliency and enabling physicians to visualize how often patients use the smartphone app so that physician-patient discussions can be more personalized and effective.
