Randomized Controlled Trial Comparative Study
A randomized, controlled trial of acceptance and commitment therapy and cognitive-behavioral therapy for chronic pain.
Individuals reporting chronic, nonmalignant pain for at least 6 months (N=114) were randomly assigned to 8 weekly group sessions of acceptance and commitment therapy (ACT) or cognitive-behavioral therapy (CBT) after a 4-6 week pretreatment period and were assessed after treatment and at 6-month follow-up. The protocols were designed for use in a primary care rather than specialty pain clinic setting. ⋯ Although there were no differences in attrition between the groups, ACT participants who completed treatment reported significantly higher levels of satisfaction than did CBT participants. These findings suggest that ACT is an effective and acceptable adjunct intervention for patients with chronic pain.

Randomized Controlled Trial Multicenter Study Comparative Study
Links between nurses' organisational work environment and upper limb musculoskeletal symptoms: independently of effort-reward imbalance! The ORSOSA study.
The role of psychosocial factors in the development of upper limb musculoskeletal disorders has now been clearly demonstrated. However, only a few studies have analysed the association between the organisational work environment and musculoskeletal disorders in health care workers. The main goal of this study was to test the hypothesis that some specific organisational constraints may be related to upper limb musculoskeletal symptoms experienced by registered nurses, independently of the effort/reward imbalance model and major confounding factors. ⋯ This study identified and quantified specific health care organisational factors that have an impact on nurses' upper limb symptoms, sometimes independently of ERI perception. A prospective study is needed to clarify the causal role of psychosocial and organisational work factors in upper limb injury in nurses. Organisational approaches may be more effective in improving health at work and may also have a longer-lasting impact than individual approaches.

Comparative Study
Reliability and validity of the Child Pain Anxiety Symptoms Scale (CPASS) in a clinical sample of children and adolescents with acute postsurgical pain.
Pain anxiety refers to the cognitive, emotional, physiological, and behavioural reactions to the experience or anticipation of pain. The Child Pain Anxiety Symptoms Scale (CPASS) has recently been developed and validated in a pediatric community sample. The goal of the present study was to examine the psychometric properties of the CPASS in a sample of children and adolescents with acute postsurgical pain. ⋯ Pain anxiety was significantly associated with pain intensity (r = 0.44) and unpleasantness (r = 0.32) 48–72 hours after surgery (concurrent validity) and with pain unpleasantness (r = 0.29) and functional disability (r = 0.50; but not pain intensity, r = 0.20) 2 weeks later (predictive validity). The CPASS showed adequate sensitivity to change over time (mean change = 9.52; effect size = 0.49) and good sensitivity and specificity. The results of the present study provide initial validity and reliability of the CPASS in a clinical sample of children and adolescents after major surgery.

Randomized Controlled Trial Comparative Study
The effects of total and REM sleep deprivation on laser-evoked potential threshold and pain perception.
We investigated the effects of total and rapid eye movement (REM) sleep deprivation on the thermal nociceptive threshold and pain perception using the objective laser-evoked potential (LEP) and the subjective visual analogue scale (VAS). Twenty-eight male adult volunteers were assigned into Control (CTRL), Total (T-SD), and REM (REM-SD) Sleep Deprivation groups. The T-SD and REM-SD volunteers were totally or selectively deprived of sleep for 2 and 4 consecutive nights, respectively. ⋯ No significant variations were observed in the REM-SD group, suggesting a predominant role for slow wave sleep rather than selective REM-SD in pain perception. Also, for both sleep-deprived groups, the mean values of the LEP threshold and VAS ratings showed a gradual increase that was proportional to the SD deprivation time, followed by a decrease after 1 night of sleep restoration. These findings demonstrate a hyperalgesic modification to pain perception (as reflected by the augmented VAS) and a concomitant increase in the LEP threshold following T-SD, an apparently contradictory effect that can be explained by differences in the ways that attention affects these pain measurements.
