RESUMO
It is not uncommon for patients to report diminished outcomes as a result of spine surgery or a spinal cord stimulator implant. Presurgical psychological evaluations are increasingly used to identify patients at increased risk for such outcomes and use of personality assessment instruments in these evaluations provides incremental information beyond a clinical interview and medical chart review. This investigation explores the psychometric properties of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) in a sample of spine surgery patients (n = 810) and in a sample of spinal cord stimulator patients (n = 533). Results indicated that MMPI-2-RF substantive scale scores are reliable, with evidence of good convergent and discriminant validity in both samples. Incorporating the MMPI-2-RF as part of the presurgical evaluation of spine surgery and spinal cord stimulator patients can provide meaningful insight into patients' functioning and help guide pre- and postsurgical treatment in these settings.
