The Effects of a Pain Psychology and Neuroscience Self-Evaluation Internet Intervention: A Randomized Controlled Trial.
Many patients' chronic musculoskeletal pain is strongly influenced by central nervous system processes such as sensitization or amplification. Education about pain neuroscience can change patients' beliefs but has less consistent effects on pain outcomes. Patients may have greater clinical benefits if the educational intervention is personalized, and they evaluate various psychosocial risk factors with respect to their pain. We developed and tested a brief, internet-based Pain Psychology and Neuroscience (PPN) self-evaluation intervention. ⋯ A brief PPN self-evaluation intervention, presented on-line, can yield short-term improvements in musculoskeletal pain severity and interference, especially for people with spinal/localized pain rather than FM, perhaps because the psychology/neuroscience perspective is more novel for such patients.

Chronic low back pain (cLBP) is the leading cause of disability, with a significant societal cost. It disproportionately affects non-Hispanic blacks and individuals of lower socioeconomic status. The biopsychosocial framework has been used to study and manage cLBP, yet disparities persist. ⋯ Higher perceived social status is associated with less severe depressive symptoms, which in turn is associated with less pain severity and less pain interference for whites but not for blacks with cLBP.

Although the great majority of individuals who take opioids for chronic pain use them appropriately and to good effect, a certain minority will develop the problematic outcome of opioid use disorder (OUD). Characteristics associated with the development of OUD in individuals with chronic pain have been described; however, relatively unexplored is how sensitivity to pain is associated with OUD outcomes. ⋯ Despite the small sample size and cross-sectional design, these findings suggest that experimental pain testing may be a novel technique in identifying patients with chronic pain likely to develop OUD, in that they are likely to evidence exacerbated temporal summation and to rate the associated pain as more severe.

This study examined the cross-sectional associations among pain intensity, pain catastrophizing, and sleep disturbance among patients receiving methadone maintenance treatment (MMT) for opioid use disorder (OUD) and reporting co-occurring chronic pain. ⋯ Altogether, findings suggest that the sleep disturbance to pain catastrophizing to pain intensity pathway may be a key mechanistic pathway exacerbating pain issues among MMT patients with OUD and chronic pain. These results suggest that interventions targeting sleep disturbance may be warranted among MMT patients with OUD and chronic pain. Future work in this area with longitudinal data is warranted.

We recently developed a transdiagnostic exposure treatment (the hybrid treatment) for chronic pain patients with concurrent emotional difficulties. This paper investigates the hypothesized treatment processes, specifically: (1) if changes on pain-related dysregulation (catastrophizing, fear-avoidance, and nonacceptance of pain) and general emotion dysregulation (difficulties to regulate a broad spectrum of emotional responses) mediate effects on outcomes; and (2) if mediation is more pronounced for patients who score higher on these processes pretreatment. ⋯ Our findings provide initial support for the transdiagnostic theoretical underpinnings of the hybrid treatment model. Using a hybrid treatment approach that centers on teaching patients emotion-regulation skills before commencing broad exposure successfully influenced both pain-related dysregulation and general emotion dysregulation, which in turn was associated with better treatment outcomes. It appears central to address these processes in pain patients with comorbid emotional problems, especially among patients scoring high on measures of catastrophizing, fear-avoidance, and nonacceptance of pain.
