Show moreCognitive impairment in individuals with chronic pain is frequently observed and clinically significant (McCracken, & Iverson, 2001). It has long been recognized that emotional factors contribute to both patient perception of impaired cognition and verifiable cognitive impairment on testing (Burt, Zembar, & Niederehe, 1995). However, scientific consensus is lacking regarding how specific emotions, such as depression, anxiety, and pain catastrophizing impact cognition in chronic pain patients. Research seeking to clarify such relationships has been hampered by methodological shortcomings, which include limited sample sizes, non-objective measures, and failure to examine multiple emotional dimensions in unique samples (McCracken and Vowels, 2014; Moriarty, McGuire, & Finn, 2011). The present study examined factors that might contribute to cognitive impairment in this population using a sample of 78 chronic pain patients evaluated for surgical candidacy for spinal cord stimulator (SCS) implantation at the University of Illinois at Chicago. Use of such a sample ensured patients were wellmotivated to perform to the best of their ability, so as to increase their chance of being cleared for such a highly desirable procedure. Additionally, the vast majority of participants passed well-validated objective measures of effort. Hypothesized associations between attentional function as measured objectively by the RBANS attention index and a number of predictor variables: depression and anxiety, subjective pain experience, pain catastrophizing, somatization, and engagement in pain behaviors were not found, and subsequent analyses of proposed mediating relationships could not be performed. However, fully a third (35.9 percent) of our well-motivated sample did not show clinically significant impairment (below 85, or 1 SD below the mean), as was expected. Thus, it is possible that a well-motivated sample may have been less likely than samples used in previous investigations to show cognitive impairment overall. Strengths and limitations of the study are discussed, as well as clinical and research implications.

Show moreAcute and chronic pain in sickle cell disease (SCD) are associated with functional impairment and depressive symptoms. Given the suboptimal management of pain in SCD and serious health risks associated with current treatment methods for pain, there is a need to identify factors associated with pain that impact functional outcomes and depression. The fear-avoidance (FA) model of chronic pain has been examined in other chronic pain populations as a means to understand how pain-related cognitive and behavioral factors contribute to functional impairment and depression, but has not been applied in individuals with SCD. The purpose of the present study was to apply the FA model of chronic pain to adults with SCD via mediation analyses. Additionally, mental flexibility was examined as a possible moderator in the FA model. Results demonstrated that pain catastrophizing mediated the relationship between pain severity and pain-related fear. No other mediators within the model were identified. Additionally, results did not demonstrate that mental flexibility moderated the relationship between pain severity and pain catastrophizing. Post-hoc exploratory analyses demonstrated that pain catastrophizing and pain-related fear significantly predicted functional impairment and depression, respectively, above and beyond pain severity. Overall, results suggest that the FA model of chronic pain does not apply to individuals with SCD and the predictive roles that pain catastrophizing and pain-related fear play in functional impairment and depression are not consistent with results in other chronic pain populations. Further studies are needed to identify factors that explain the relationship between pain, functional impairment, and depression so that these factors may be targeted for intervention as a means to improve pain, mood, and functional independence.

Show moreIndividuals who acquire a spinal cord injury (SCI) during their pediatric years are unique from individuals who acquire an SCI during adulthood due to the heightened risks for developing secondary health conditions and chronic pain. These concerns may significantly impede developmental milestones and experiences, such as social participation, that may decrease life satisfaction. Thus, research on pain characteristics (e.g., frequency of pain, duration of pain, level of current pain, and level of general pain) alongside the role of emotional support and social participation on life satisfaction in adults with pediatric-onset SCI is needed. This study sample consisted of 205 individuals with pediatric-onset SCI who were former patients at pediatric hospitals in three metropolitan cities. Participants were individuals who were 19 years of age or older at the time of the interview, with the age of injury at 18 years or prior. Associations between demographic, pain, and injury characteristics, emotional support, social participation, and life satisfaction were assessed via bivariate Pearson correlations and a 3-block hierarchical multiple linear regression with LS as the primary outcome. Although pain characteristics and emotional support were not associated with life satisfaction among adults who sustained a pediatric-onset SCI, social participation was positively associated with life satisfaction. These findings suggest that clinicians should evaluate various pain characteristics and highlight the role of social participation when treating individuals with SCI.
