Pain: May 2011 - Volume 152 - Issue 5 - p 1096-1103 doi: 10.1016/j.pain.2011.01.019 Buy Metrics Abstract The aims of the PRIME study (Prevalence, Impact and Cost of Chronic Pain) were 3-fold: (1) to determine the point prevalence of chronic pain in Ireland; (2) to compare the psychological and physical health profiles of those with and without chronic pain; and (3) to explore a predictive model of pain-related disability. A postal survey of 3136 people was conducted with a representative community-based sample of adults. Measures were obtained for sociodemographic variables, physical and psychological well-being, depressive symptoms, presence of pain, pain severity, pain-related disability, and illness perceptions. Responses were received from 1204 people. The prevalence of chronic pain was 35.5% (95% CI = 32.8–38.2) (n = 428). No gender difference in prevalence was found. Prevalence of pain increased with age and was associated with manual employment. The most commonly reported site of pain was the lower back (47.6%); however, multiple pain sites was the norm, with more than 80% of participants reporting more than 1 pain site. Approximately 12% of participants were unable to work or were on reduced work hours because of pain. Of those with chronic pain, 15% met the criteria for clinically relevant depression compared with 2.8% of those without pain. A multiple regression analysis, predicting 67% of variance, showed that pain intensity was the strongest predictor of pain-related disability. Depression and illness perceptions were also predictive of pain-related disability, after controlling for the effects of pain intensity. Chronic pain is a prevalent health problem in Ireland and is associated with significant psychological and functional disability. Psychological factors appear to influence the level of pain-related disability. Chronic pain affects approximately one-third of the population in Ireland, and depressive symptoms occur 5 times more often than in persons without chronic pain. © 2011 Lippincott Williams & Wilkins, Inc.
