Children who develop greater negatively-biased recall of pain (ie, recalled pain is higher than the initial pain report) following surgery are at risk for developing chronic pain; therefore, identifying risk factors for the development of biased pain memories is important. Higher anxiety has been implicated in the development of greater negatively-biased recall of pain; however, studies have not examined anxiety at multiple time points before and after a surgery and its relationship to children's postsurgical pain memories after 1 year. This prospective study examined a cohort of 237 children and adolescents undergoing major surgery. ⋯ Specifically, higher anxiety sensitivity at baseline and greater tendencies to catastrophize about pain at baseline and in the immediate acute recovery phase were most strongly linked to greater negatively-biased recall of pain. Greater negatively-biased recall of pain was related to higher pain intensity at 6 and 12 months post surgery. Findings support conceptual models of anxiety and pain memory biases and can inform intervention efforts to reduce anxiety in the pre- and post-op periods to minimize negative biases in pain memories.

This study was performed to test whether the risk of developing chronic widespread pain (CWP) in those with regional pain was augmented in those with symptoms of neuropathic pain (NP). Persons free of CWP completed the Douleur Neuropathique 4 (scores ≥3 indicating NP); demographics; Hospital Anxiety and Depression scale; Pittsburgh Sleep Quality Index; and pain medications. Participants were classified as having no pain, regional pain with no symptoms of NP ((Equation is included in full-text article.)), or regional pain with symptoms of NP (NP). ⋯ The NP group were not more likely to develop CWP when compared directly with (Equation is included in full-text article.)(1.5 [0.8-2.8]). Neuropathic pain was relatively rare and predicted a small number of new-onset CWP cases. Using these estimates, treatments targeting NP would at best prevent 6% of CWP cases.
