Abstract
Objective: Emotion regulation (ER) includes a set of cognitive and attentional processes used to change or maintain emotional state. A small but growing body of research suggests that maladaptive ER might be a risk factor for the development of chronic pain. This review aims to summarize existing literature on the association between ER and chronic pain, and to determine whether the construct of ER may further enhance our under- standing of the risk and protective factors that may contribute to the onset and maintenance of chronic pain. Methods: A systematic search was conducted using the search terms " chronic pain " and " emotion regulation. " Studies that measured both constructs across all age groups were included. Results: We found 15 studies that met our inclusion criteria. Nine studies were completed within the last fi ve years, suggesting that the evaluation of ER as it relates to pain is a new line of research. Studies that measured " response-focused " ER found associations between maladaptive ER and pain. Studies that measured " antecedent- focused " ER strategies were less likely to show a direct association with pain. Conclusion: Maladaptive response-focused ER may be an important risk factor in the development and main- tenance of chronic pain, as it is associated with pain and psychological comorbidities. Adding ER to chronic pain investigations may help to further explain individual di ff erences in the risk and protective mechanisms that are known to in fl uence chronic pain. Importantly, this line of research has potential to directly inform future in- terventions for patients with chronic pain.
