Reliability and Validity of the Minnesota Multiphasic Personality Inventory - 2 - Restructured Form (MMPI-2-RF) in Spine Surgery and Spinal Cord Stimulator Samples.

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 ( = 810) and in a sample of spinal cord stimulator patients ( = 533).

Associations Between Pre-Implant Psychosocial Factors and Spinal Cord Stimulation Outcome: Evaluation Using the MMPI-2-RF.

Spinal cord stimulation (SCS) has variable effectiveness in controlling chronic pain. Previous research has demonstrated that psychosocial factors are associated with diminished results of SCS. The objective of this investigation is to examine associations between pre-implant psychological functioning as measured by the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and SCS outcomes.
