Background. Comorbid chronic pain and post-traumatic stress disorder (PTSD) complicate the treatment of both conditions. Previous research has identified pain catastrophizing as a potentially important variable contributing to the relationship between chronic pain and PTSD. However, little is known regarding how the different dimensions of pain catastrophizing—rumination, magnification, and helplessness—uniquely contribute to the relationship between PTSD symptomatology and measures of pain outcome. Methods. 491 treatment seeking participants were admitted to a three-week interdisciplinary pain rehabilitation program between July 2016 and March 2020. The patients completed measures of pain severity, pain interference, pain catastrophizing, depressive symptoms, quality of life (QOL), and PTSD symptoms at pretreatment. Results. Parallel mediation analyses were conducted to evaluate the mediating effect of the Pain Catastrophizing Scale subscales on the relationship between PTSD symptomatology and pain-relevant variables. The helplessness subscale accounted for significant unique variance in the relationship between PTSD symptomatology and pain severity (b = 0.010, SE = 0.002, 95% CI: 0.006, 0.014), pain interference (b = 0.004, SE = 0.002, 95% CI: 0.001, 0.008), and mental health QOL (b = −0.117, SE = 0.031, 95% CI: −0.179, −0.059), while the rumination and magnification subscales had no significant influence. Conclusions. Pain catastrophizing is a multifaceted construct. These results suggest that the helplessness dimension of pain catastrophizing may be the primary target when treating patients with comorbid chronic pain and PTSD symptoms. This study represents the first to evaluate the influence of the individual dimensions of pain catastrophizing on the relationship between PTSD symptomatology and chronic pain outcome.

Objective: Coprevalence of chronic pain and posttraumatic stress disorder (PTSD) negatively impacts the course of both disorders. Patients diagnosed with both conditions report greater pain, affective distress, and disability when compared with those with either chronic pain or PTSD alone. While the prevalence and complexity of the comorbidity is widely acknowledged, there is a dearth of research examining potential mechanism variables that might account for the relationship between chronic pain and PTSD. The current study utilizes a series of mediation analyses to examine if pain catastrophizing mediates the relationship between PTSD symptomatology and chronic pain outcome. Materials and Methods: A total of 203 treatment-seeking participants admitted to a 3-week interdisciplinary pain rehabilitation program completed a battery of psychometrically validated measures of pain severity, pain interference, pain catastrophizing, depressive symptoms, and PTSD symptoms at program admission. Results: A series of multiple parallel mediation analyses revealed that pain catastrophizing fully mediated the relationships between PTSD symptoms and pain outcome (ie, pain severity and pain interference) above and beyond the influence of depressive symptoms. Discussion: Results suggest that pain catastrophizing may represent an important cognitive mechanism through which PTSD symptoms influence the experience of chronic pain. Psychosocial treatment approaches that directly target tendency to catastrophize in response to pain may hold the potential to have salutary effects on both chronic pain and PTSD.

Background: Lack of wellness among physicians has been associated with increased risk for physical and mental illness, interpersonal discord, and occupational liability. In academic primary care practices, physician wellness and self-care behaviors have been associated with improved patient outcomes. With the increase in team-based care structures in primary care clinics and residencies there may be opportunities to promote wellness among primary clinicians, particularly among resident physicians who are at increased risk for decreased well being. The primary objective of the study was to test an a priori hypothesis that family medicine residents’ perception of support from preceptor team leads would be associated with wellbeing. A secondary objective of the study was to test a post hoc hypothesis that examined whether the relationship between residents’ perception of support from their preceptor team leads would be associated with residents’ well being, while controlling for self-care behaviors. Methods: Our study utilized a prospective cross-sectional design with purposive sampling to survey family medicine residents. Data were collected in February 2016. The survey was sent out to 58 family medicine residents across three family medicine residencies at Mayo Clinic. The survey response rate was 55% (n=32); Ten (31.3%) residents reported being in their PGY-1, 11 (34.4%) in PGY-2; and 11 (34.4%) in PGY-3; participants included 19 (59.4%) women and 13 (40.6%) men. The Brief Resident Wellness Profile (BRWP) was utilized to assess family medicine residents’ perceived sense of professional accomplishment and mood in the past week. Results: In bivariate correlational analyses, increased perception of support from preceptor team leads (r=.40, P<.01) and reporting a male gender (r=.43, P<.01) was associated with increased resident wellness. In exploratory multivariate analysis, results suggested that while controlling for gender, frequency of self-care behaviors, and perceived preceptor team lead support, a one-point change on rating of perceived team leader support is associated with a 1.69 increase in resident wellness score on the BRWP. Conclusions: Our results provide preliminary evidence to support the relationship between preceptor team lead support and resident wellness in team-based care, above and beyond the impact that self-behaviors have on wellness. Our findings suggest evidence for the subsequent study of the impact of preceptor team lead relationship quality on resident wellness.
