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 moreSocial ostracism, the willful exclusion and ignoring of individuals, almost universally leads to feelings of decreased well-being and self-esteem through a neurobehavioral path similar to that responsible for physical pain (Eisenberger, Jarcho, Lieberman, Naliboff, 2006), negatively impacting overall life satisfaction (Zadro, Williams, and Richardson, 2004). This study aimed to compare the potential therapeutic benefits of acceptance based approaches, used in Acceptance and Commitment Therapy, to traditional control based approaches, such as thought blocking, in mitigating the pain of social ostracism. Participants were 111 college students. Each participant was randomly assigned to receive a brief acceptance, thought blocking, or visualization exercise before being socially ostracized through a computerized virtual ball toss paradigm. Subjective correlates of pain experience, including anger, general mood, belonging, control, self-esteem, and meaningful existence were assessed using a measure developed by Zadro, Williams, and Richardson (2004). Results revealed that participants who had received the acceptance exercise reported significantly more meaningful existence following social exclusion. Results are discussed in the context of previous research on social pain and meaningful existence (incorporating quality of life), as well as future research directions for finding strategies for mitigating the pain of social ostracism.
