Background and Objective: Pediatric debilitating chronic pain is a severe health problem, often requiring complex interventions such as intensive interdisciplinary pain treatment (IIPT). Research is lacking regarding the effectiveness of IIPT for children. The objective was to systematically review studies evaluating the effects of IIPT., Methods: Cochrane, Medline/Ovid, PsycInfo/OVID, PubMed, PubPsych, and Web of Science were searched. Studies were included if (1) treatment was coordinated by ≥3 health professionals, (2) treatment occurred within an inpatient/day hospital setting, (3) patients were <22 years, (4) patients experienced debilitating chronic pain, (5) the study was published in English, and (6) the study had ≥10 participants at posttreatment. The child's pain condition, characteristics of the IIPT, and 5 outcome domains (pain intensity, disability, school functioning, anxiety, depressive symptoms) were extracted at baseline, posttreatment, and follow-up., Results: One randomized controlled trial and 9 nonrandomized treatment studies were identified and a meta-analysis was conducted separately on pain intensity, disability, and depressive symptoms revealing positive treatment effects. At posttreatment, there were large improvements for disability, and small to moderate improvements for pain intensity and depressive symptoms. The positive effects were maintained at short-term follow-up. Findings demonstrated extreme heterogeneity., Conclusions: Effects in nonrandomized treatment studies cannot be attributed to IIPT alone. Because of substantial heterogeneity in measures for school functioning and anxiety, meta-analyses could not be computed. There is preliminary evidence for positive treatment effects of IIPT, but the small number of studies and their methodological weaknesses suggest a need for more research on IIPTs for children., (Copyright © 2015 by the American Academy of Pediatrics.)

An introduction is presented in which the editor discusess topics within the issue including prevention of pain in children; behavioral and psychological pain research in children; and acute to chronic pain transition for different types of pain conditions.

Although pain and function improve at immediate posttreatment for youth receiving cognitive behavioral therapy for chronic pain, limited data are available to understand changes that youth make during psychological treatment. Wesought to characterize distinct trajectory patterns of change in pain and function to understand the temporal association of these changes during internet-delivered cognitive behavioral therapy (CBT). Weekly repeated assessments of pain and function were conducted during 8 weeks of treatment among 135 adolescents, aged 11 to 17 years, with chronic pain who were randomized to the cognitive behavioral intervention arm of an ongoing trial of internet-delivered CBT (Web-based management of adolescent pain; Web-MAP2). Using random-effects growth mixture models, we characterized pain and functional disability trajectories finding distinct trajectory groups indicating patterns of both linear and quadratic effects. Trajectories of change showed that some patients' pain and functional disability were improving, others worsened or changed minimally. Paired t tests compared the within-subject relative change rate in pain and function demonstrating similar change range for pain and function during the treatment period. There was no support for improvements in either pain or function to precede changes in the other domain. Findings may be useful in informing future studies of psychosocial treatments for pediatric chronic pain to consider how to target treatment strategies to distinct patient response profiles. This may lead to the development of intervention strategies that can both more effectively target children's pain and function during treatment and lead to sustained changes after treatment.
