To assess which psychological factors are important in the development of chronic whiplash symptoms. ⋯ Poor expectations of recovery, posttraumatic stress symptoms and passive coping emerged as the most consistent prognostic factors of chronic neck pain and/or disability after a whiplash injury. Anxiety, travel anxiety, depression, personality, precollision distress, general psychological distress, and avoidance behavior were not associated with chronic whiplash problems.

Perceived injustice (PI) has been identified as an important risk factor for pain-related outcomes. To date, research has shown that pain acceptance and anger are mediators of the association between PI and pain-related outcomes. However, a combined conceptual model that addresses the interrelationships between these variables is currently lacking. Therefore, the current study aimed to examine the potential mediating roles of pain acceptance and anger on the association between PI and adverse pain-related outcomes (physical function, pain intensity, opioid use status). ⋯ This is the first study to provide a combined conceptual model investigating the mediating roles of pain acceptance and anger on the relationship between PI and pain outcomes. On the basis of our findings, low levels of pain acceptance associated with PI may help explain the association between PI and adverse pain outcomes. Clinical and theoretical implications are discussed.

Meta Analysis
Neurophysiological Pain Education for Patients With Chronic Low Back Pain: A Systematic Review and Meta-Analysis.
To evaluate the effect of neurophysiological pain education (NPE) for patients with chronic low back pain (CLBP). ⋯ There was moderate evidence supporting the hypothesis that NPE has a small to moderate effect on pain and low evidence of a small to moderate effect on disability immediately after the intervention. NPE has a small to moderate effect on pain and disability at 3 months follow-up in patients with CLBP.

Research on labor pain currently uses standard scores such as numerical scales as clinical outcomes, but no clear guidelines for such an assessment have appeared since a review published in 1998. We aimed to describe and estimate the quality of the methods used to assess and analyze such outcomes in a systematic review of 215 comparative studies published since then in 27 influential journals. ⋯ This review points out the need for a better standardization of the methods in this field of research.

Controlled Clinical Trial
Effectiveness of Sucrose Used Routinely for Pain Relief and Neonatal Clinical Risk in Preterm Infants: A Nonrandomized Study.
Preterm infants (PI) requiring the neonatal intensive care unit are exposed to early repetitive pain/distress. Little is known about how pain relief strategies interact with infants' clinical health status, such as severity of illness with pain responses. This study aimed to examine main and interactive effects of routine sucrose intervention and neonatal clinical risk (NCR) on biobehavioral pain reactivity-recovery in PI during painful blood collection procedures. ⋯ Independent of NCR level, sucrose intervention for pain relief during acute painful procedures was effective to reduce pain intensity and increase biobehavioral regulation.
