Résumé
Objective: Pain and prescription opioid medication use are prevalent and a major source of psychological and physical health burden. This research examines whether Five Factor Model personality traits prospectively predict who will experience persistent pain and use prescription opioid medication over a 10-year follow-up.
Methods: Participants (N = 8491) were drawn from the Health and Retirement Study. At baseline, participants reported on their personality and whether they were in pain. Every two years, participants reported on their pain and, at the most recent assessment, their current use of prescription opioid medication. Logistic regression was used to test whether personality was associated with persistent pain over the up to 10-year follow-up and whether it predicted who would be taking prescription opioid medication.
Results: Neuroticism was associated with higher risk of persistent pain (OR = 1.44, 95% CI = 1.38-1.51) and opioid medication use (OR = 1.21, 95% CI = 1.14-1.29) over the follow-up. Extraversion was associated with lower risk of persistent pain (OR = 0.83, 95% CI = 0.80-0.87) and opioid medication use (OR = 0.92, 95% CI = 0.86-0.97). Similarly, Conscientiousness was associated with lower risk of persistent pain (OR = 0.83, 95% CI = 0.79-0.87) and opioid medication use (OR = 0.91, 95% CI = 0.86-0.97).
Conclusions: The findings suggest that personality traits are one psychological characteristic that modulates the likelihood of persistent pain and opioid medication use.
