Distinct developmental trajectories for neck disability and posttraumatic stress disorder (PTSD) symptoms after whiplash injury have recently been identified. This study aimed to identify baseline predictors of membership to these trajectories and to explore their dual development. In a prospective study, 155 individuals with whiplash were assessed at <1 month, 3, 6, and 12 months postinjury. ⋯ These findings support the proposal of links between the development of chronic neck related disability and PTSD after whiplash injury. Developmental trajectories of disability and posttraumatic stress disorder (PTSD) after whiplash injury are mostly in synchrony, and similar factors predict their membership. This suggests links between the development of chronic neck pain-related disability and PTSD.

Chronic pain is a common reason for medical visits, but prevalence estimates vary between studies and have rarely included drug treatment data. This study aimed to examine characteristics of chronic pain and its relation to demographic and health factors, and factors associated with treatment of pain with opioid analgesics. A chronic pain module was added to the 2007 Kansas Behavioral Risk Factor Surveillance System (response rate = 61%). ⋯ S. A. Overall, 45.7% of people who take prescription drugs for chronic pain reported taking opioid analgesics.

It has been proposed that goal pursuit plays a role in the development of chronic pain disorders. On the basis of (affective) motivational theories, it was hypothesized that both long-term achievement goals and short-term hedonic goals would be related to increased levels of pain and disability, particularly in patients with high negative affect. Participants with musculoskeletal pain complaints (N=299) completed a battery of questionnaires including a novel goal pursuit questionnaire (GPQ) measuring the extent to which participants preferred hedonic goals (mood-management or pain-avoidance goals) over achievement goals in various situations. ⋯ These findings provide support for the validity of an affective-motivational approach to chronic pain, suggesting that the experience of pain and the interference of pain on daily life activities depends on goal pursuit and negative affect. Interventions aimed at improving disability in chronic pain should address both patient's goal pursuit and negative affect. An affective-motivational approach to chronic pain indicates that achievement and pain-avoidance goals are associated with pain severity and disability, particularly in patients with high negative affect.

No validated screening tasks exist to distinguish children who can accurately use self-report pain measures from those who cannot. Children aged 3-7 years (n=108), each with a parent, provided data before and after day surgery. Parents rated how well they thought their child could understand the Faces Pain Scale-Revised (FPS-R), and children completed 4 screening tasks in counterbalanced order, such as rating pain in vignettes and selecting a middle-sized cup. ⋯ We failed to identify a screening tool that was better than chronological age in identifying which children could accurately self-report pain using the FPS-R. Future research should explore other screening tasks, training methods, and simplified approaches to pain assessment for young children. The ability to use self-report pain scales usually develops from age 3 to 7 years, but no valid screening method exists to identify this achievement.
