Multicenter Study
Assessment and validation of prognostic models for poor functional recovery 12 months after whiplash injury: a multicentre inception cohort study.
Uncertainty surrounds prognostic factors after whiplash injury. Previously we identified a prognostic model for 6-month pain-related disability in a cohort of 80 participants with acute whiplash. Predictors included initial disability, older age, decreased cold pain thresholds, decreased neck rotation movement, posttraumatic stress symptoms and decreased sympathetic vasoconstriction. ⋯ After adjusting for site, age and Impact of Events Scale scores regained significance (r(2) = 0.56, 95% confidence interval 0.48 to 0.64). The tested model was not precise in predicting NDI as a continuous variable. However, it found good accuracy to discriminate participants with moderate to severe disability at 12 months (area under the receiver operating characteristic curve 0.89 [95% confidence interval 0.84-0.94], P<.001) which is clinically useful.

Multicenter Study
Parents who catastrophize about their child's pain prioritize attempts to control pain.
How parents respond to their child in pain is critically important to how both parent and child attempt to cope with pain. We examined the influence of parental catastrophic thinking about child pain on their prioritization for pain control. Using a vignette methodology, parents reported, in response to different pain scenarios, on their imagined motivation for 2 competing goals: to control their child's pain (ie, pain control) or to encourage their child's participation in daily activities (ie, activity engagement). ⋯ Furthermore, independently of parental catastrophic thoughts, heightened priority for pain control was observed in highly intense and chronic pain situations. Moreover, in highly intense pain, priority for pain control was stronger for mothers compared with fathers. Theoretical and clinical implications and directions for future research are discussed.
