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. SCS candidates at two sites (total N = 319) completed the MMPI-2-RF and measures of pain, emotional distress, and functional ability as part of a pre-implant psychological evaluation. At an average of 5 months post-implant, patients completed the measures of pain and emotional distress a second time. Poorer SCS outcomes and poorer patient satisfaction were associated with higher pre-implant MMPI-2-RF scores on scales used to assess emotional dysfunction, somatic/cognitive complaints, and interpersonal problems. Ways through which pre-implant psychological evaluations of spinal cord stimulator candidates can be informed by MMPI-2-RF findings are discussed.
脊髓刺激（SCS）在控制慢性疼痛方面效果不一。先前的研究表明，社会心理因素与SCS效果减弱有关。本研究的目的是检验通过明尼苏达多相人格调查表第二版修订版（MMPI-2-RF）测量的植入前心理功能与SCS结果之间的关联。两个地点的SCS候选者（总数N = 319）完成了MMPI-2-RF以及疼痛、情绪困扰和功能能力的测量，作为植入前心理评估的一部分。植入后平均5个月，患者再次完成疼痛和情绪困扰的测量。在用于评估情绪功能障碍、躯体/认知主诉和人际问题的量表上，植入前MMPI-2-RF得分较高与较差的SCS结果和较低的患者满意度相关。本文讨论了MMPI-2-RF结果可为脊髓刺激器候选者植入前心理评估提供信息的方式。
