There is a demonstrated link in the research literature between (a) psychological factors and neuromodulation outcomes, and (b) marital/intimate support and surgical outcomes. One such neuromodulation therapy, spinal cord stimulation (SCS), is becoming increasingly popular and is the focus of much clinical and research attention due to highly variable patient outcomes. Prior research on SCS provides sparse and conflicting evidence that psychological factors contribute to SCS outcomes. Additionally, findings are not clear regarding the predictive value of psychological testing in long-term SCS outcomes. The purpose of the present study was to investigate the utility of psychological assessments in predicting postoperative pain by utilizing a longitudinal design in which several psychological domains (depression, anxiety, perceived social support, coping, anger, pain intensity and pain sensitivity) were assessed. Specifically, using pain intensity as the dependent measure, it was hypothesized that psychological factors assessed pre-operatively would predict postsurgical pain based on time course. Data are presented for 58 patients with chronic, intractable pain who were recruited from a large midwestern university hospital. All patients underwent permanent placement of SCS after undergoing a psychological assessment that included: a clinical interview and administration of a battery of standardized measures (Minnesota Multiphasic Personality Inventory-2, Beck Depression Inventory, Multidimensional Pain Inventory, State-Trait Anxiety Inventory, Coping Strategies Questionnaire). As determined by a multivariate model, significant associations (P <= 0.05) were observed between psychological test results and surgical outcomes after controlling for possible confounds (e.g. body mass index, demographic variables). The multivariate model also identified longer duration of pain condition and heightened pain sensitivity to be predictive of increased post-surgical pain. Additionally, results suggest a positive association between marital status and post-surgical pain intensity. The findings from this study lend support for the utility of psychological assessment in patient selection for SCS
