Abstract
Psychological factors are capable of influencing an individual's perception of pain and may mediate the evolution from acute to chronic pain. Personality characteristics, such as alexithymia and anxiety sensitivity, can also influence perception of pain by somatising psychological distress associated with acute pain. The aim of this study was to understand if alexithymia and anxiety sensitivity interact with psychological distress at an early stage of recovery from orthopaedic injury, to accentuate perception of pain intensity and potentially mediate the development of chronic pain disorder. 62 patients who had recently suffered orthopaedic injury completed the British Pain Society Pain Rating Scale plus the Hospital Anxiety and Depression Scale, as well as measures of alexithymia and anxiety sensitivity. Pain intensity correlated with each of the psychological measures but a regression analysis found that only depression, in combination with anxiety sensitivity, contributed to a significant amount of the variance in pain scores. The authors suggest that early screening after orthopaedic injury could identify those vulnerable to developing persisting pain disorders. This could lead to effective early intervention using psychological methods of pain management to reduce the risk of acute pain evolving into a chronic pain disorder.
