Multicenter Study Clinical Trial
The validity and reliability of the graphic rating scale and verbal rating scale for measuring pain across cultures: a study in Egyptian and Dutch women with rheumatoid arthritis.
To compare the validity and reliability of a graphic rating scale (GRS) and a verbal rating scale (VRS) for measuring pain intensity in young female Egyptian and Dutch patients with rheumatoid arthritis (RA). ⋯ The study confirmed that the GRS and VRS were reliable and valid in the total study cohort. Within the individual countries, the GRS seemed to perform better than the VRS.

Randomized Controlled Trial
A randomized, placebo-controlled study of fentanyl buccal tablet for breakthrough pain in opioid-treated patients with cancer.
Cancer-related breakthrough pain (BTP) is typically managed with a short-acting oral opioid, taken as needed during a fixed-schedule opioid regimen. The conventional approach may not provide the onset of analgesia required for BTP for many patients, because the onset of analgesia with short-acting opioids lags behind the time course of the majority of episodes of BTP. The fentanyl buccal tablet (FBT) employs a novel delivery system that enhances the rate and extent of absorption of fentanyl through the buccal mucosa. This double-blind, randomized, placebo-controlled study evaluated the efficacy, safety, and tolerability of FBT in opioid-treated patients with cancer-related BTP. ⋯ FBT is efficacious and safe in the treatment of cancer-related BTP.

Randomized Controlled Trial
Sensitivity to change and internal consistency of the Northwick Park Neck Pain Questionnaire and derivation of a minimal clinically important difference.
To estimate the sensitivity to change and internal consistency of the Northwick Park Neck Pain Questionnaire (NPQ) and derive its minimal clinically important difference (MCID). ⋯ These results show high internal consistency and sensitivity to change for the NPQ, and provide an MCID that allows participants with varying levels of severity to demonstrate improvement.

Extramedical prescription pain reliever use has generated much public concern; however, little is known regarding its epidemiology in the general population. ⋯ This study supplies data that can improve our understanding of factors associated with the extramedical use of prescription pain relievers among 2 distinct stages of use.

To examine the factor structure of the Beck Depression Inventory version II (BDI-II) in patients seeking treatment for chronic pain, using exploratory and confirmatory factor analysis and provide comparative data for use with similar patient populations. In addition, to consider the utility of using BDI-II subscale scores to further inform the management of patients with chronic pain. ⋯ Results are consistent with studies using previous versions of the BDI in suggesting that 2-factor scores may be more clinically useful in the assessment of patients referred with chronic pain.
