Psychological assessment is recommended for patients undergoing spinal cord stimulation (SCS) therapy based on evidence that it leads to better outcomes. A brief psychological evaluation can identify potential mental health issues like depression or anxiety that are common in chronic pain patients and associated with poorer prognoses. It also aims to ensure patients have realistic expectations of SCS and a plan for managing their pain should the treatment not achieve the desired level of relief. While certain personality traits alone may not predict outcomes, evaluations can help optimize patient selection and preparation for SCS.
