This study examined the impact of transdiagnostic psychosocial factors such as pain-related anxiety, anxiety sensitivity, emotion dysregulation, and distress tolerance on chronic pain and opioid outcomes. The results indicate that these factors have independent effects on pain and opioid outcomes, with pain-related anxiety most strongly related to pain intensity and interference, anxiety sensitivity related to opioid misuse, and emotion dysregulation related to all studied criterion variables.
Chronic pain is a significant public health problem associated with functional impairment, increased medical expenditures, and opioid misuse. Recent work has suggested that certain transdiagnostic psychosocial factors may be more important than pain intensity to better understand pain and opioid outcomes. Specifically, pain-related anxiety, anxiety sensitivity, emotion dysregulation, and distress tolerance have all been uniquely associated with both pain and opioid outcomes across a range of samples. Yet, no work has examined how these transdiagnostic constructs relate to pain and opioid misuse when accounting for the other constructs. Therefore, the current study employed two independent sample of adults with chronic pain to examine (1) the construct independence of each of these factors using exploratory structural equation modelling (ESEM) and (2) how each of these constructs relates to pain and opioid outcomes in latent structural models. Results from Study 1 provided empirical support for construct independence of the transdiagnostic constructs. Findings from Study 2 indicated that pain-related anxiety was most strongly related to pain intensity, interference, and pain-related negative affect, anxiety sensitivity with opioid misuse, and emotion dysregulation with all studied criterion variables. The current results highlight the importance of assessing and targeting transdiagnostic constructs among adults with pain.
