Here are some interesting articles I found during a quick search on chronic pain statistics, disability, and possible malingering:
"...16.4% of the subjects with chronic pain were depressed compared with 5.7% among those with no chronic pain."
Among the major adjustments that chronic pain sufferers have made are such serious steps as taking disability leave from work (20%), changing jobs altogether (17%), getting help with activities of daily living (13%) and moving to a home that is easier to manage (13%).
Women were more likely to experience pain (in the form of migraines, neck pain, lower back pain, or face or jaw pain) than men. Women were twice as likely to experience migraines or severe headaches, or pain in the face or jaw, than men.
The percentage of person experiencing migraines or severe headaches was inversely related to age. Twenty percent adults aged 18-44 years experienced a migraine or severe headache in the 3 months prior to the interview compared with 15% of adults aged 45-64, 7% of adults aged 65-74, and 6% of adults aged 75 and over.
Adults aged 18-44 years were less likely to have experienced pain in the lower back during the 3 months prior to the interview compared with older adults.
When results are considered by singe race without regard to ethnicity, Asian adults were less likely to have pain in the lower back compared to white adults, black adults, and American Indian or Alaska Native (AIAN) adults.
Adults with a bachelor’s degree or higher were less likely to have migraine headaches, neck pain, lower back pain, or pain in the face or jaw, compared to adults who did not graduate from high school.
Adults in poor and near poor families were more likely to experience migraine headaches, neck pain, lower back pain, or pain in the face or jaw in the 3 months prior to the interview than were adults in families that were not poor.
Among adults under age 65, those covered by Medicaid were more likely to have migraine headaches, neck pain, lower back pain, or pain the face or jaw than those with private insurance or those who were uninsured. Among adults aged 65 and over, those covered by Medicaid and Medicare were more likely to have migraine headaches, neck pain, lower back pain, or pain in the face or jaw than those with private insurance or only Medicare health care coverage.
Base rates of malingering and symptom exaggeration
Twenty-nine percent of personal injury, 30% of disability, 19% of criminal, and 8% of medical cases involved probable malingering and symptom exaggeration. Thirty-nine percent of mild head injury, 35% of fibromyalgia/chronic fatigue, 31% of chronic pain, 27% of neurotoxic, and 22% of electrical injury claims resulted in diagnostic impressions of probable malingering. Diagnosis was supported by multiple sources of evidence, including severity (65% of cases) or pattern (64% of cases) of cognitive impairment that was inconsistent with the condition, scores below empirical cutoffs on forced choice tests (57% of cases), discrepancies among records, self-report, and observed behavior (56%), implausible self-reported symptoms in interview (46%), implausible changes in test scores across repeated examinations (45%), and validity scales on objective personality tests (38% of cases).
