Does the conscious exaggeration scale detect deception within patients with chronic pain alleged to have secondary gain?

Objectives: The illness behavior questionnaire (IBQ) is a test battery developed by Pilowsky to detect what he has termed abnormal illness behavior, which includes malingering. The IBQ has been widely utilized in patients with chronic pain (PWCP). Clayer developed a 21-item scale out of the IBQ, which he termed the conscious exaggeration (CE) scale.

Relationships between functional capacity measures and baseline psychological measures in chronic pain patients.

The extent to which baseline psychological measures, pain, and compensation status are related to admission and posttreatment functional capacity and employment outcome was investigated. Four pass/fail functional capacity tests based on the DOT (Dictionary of Occupational Titles) classification system and previously shown to be predictive of treatment outcome in chronic pain patients were analyzed in relation to baseline measures of depression, state and trait anxiety, and perceived stress. Statistical tests of all measures with employment level at admission to treatment, 1 month follow-up and at long-term follow-up were also performed.

Are opioid-dependent/tolerant patients impaired in driving-related skills? A structured evidence-based review.

Previous reviewers have concluded that opioids cause dose-related impairment in opioid-naive volunteers on psychomotor skills related to driving. Data relating to opioid-dependent/tolerant patients have not yet been reviewed. To determine what evidence, if any, exists for or against opioid-related driving skill impairment in opioid-dependent/tolerant patients, we performed a structured evidence-based review of all available studies addressing the issue of whether opioid-dependent/tolerant patients are impaired in driving-related skills.

Physical findings in patients with chronic intractable benign pain of the neck and/or back.

Chronic intractable benign pain (CIBP) is defined as non-neoplastic pain of greater than 6 months duration without objective physical findings and known nociceptive peripheral input. To test the CIBP concept, 283 consecutive chronic pain patients were examined independently by a neurosurgeon and physiatrist and only congruent physical findings were coded. Because they did not fit the CIBP definition, patients with the following primary treatment diagnoses were eliminated: degenerative disease of the spine and spinal stenosis; degenerative disease of the hips; radiculopathy; malignancy; deafferentation pain; and miscellaneous.
