“…Indeed, chronic pain patients have reported greater levels of anhedonia and decreased responsiveness to rewards, relative to healthy controls (Elvemo, Landrø, Borchgrevink, & Håberg, 2015), and distress tolerance has been implicated in emotion regulation and coping among persons with chronic pain (Hamilton, Karoly, & Kitzman, 2004). Moreover, decades of research have consistently demonstrated that greater levels of anxiety sensitivity predict a range of negative pain-related outcomes, including greater use of analgesic medications, greater cognitive bias toward pain experiences, and greater activation of fear-avoidance mechanisms (e.g., pain-related fear) that contribute to the development and maintenance of pain-related disability (e.g., Asmundson & Norton, 1995; Keogh & Cochrane, 2002; Wong et al, 2014). Thus, we suggest that transdiagnostic factors relevant to anxiety/depression should also be considered when addressing complex interrelations among affect, pain, and tobacco smoking.…”
