Athletic concussion is a growing focus of attention for pediatricians. Although numerous literature reviews and clinical guidelines are now available pertaining to athletic concussion, few have focused on the pediatric athlete in particular. Sport-related concussions occur relatively frequently in children and adolescents, and primary health care providers(More)
Little scientific attention has been aimed at the non-acute clinical care of pediatric mild TBI. We propose a clinical management model focused on both evaluation and intervention from the time of injury through recovery. Intervention strategies are outlined using a framework encompassing four relevant domains: the individual youth, family, school, and(More)
The effects of childhood traumatic brain injury (TBI) on social problem-solving were examined in 35 children with severe TBI, 40 children with moderate TBI, and 46 children with orthopedic injuries (OI). The children were recruited prospectively following injuries that occurred between 6 and 12 years of age. They were followed longitudinally, and ranged(More)
This study was part of a randomized clinical trial comparing the central nervous system effects of the two vital organ-support methods used in infant cardiac surgery: total circulatory arrest and low-flow cardiopulmonary bypass. The extent to which visual-spatial deficits are (1). associated with surgical and perioperative variables, (2). attributable to(More)
OBJECTIVE The Standardized Assessment of Concussion (SAC) is a validated tool for identifying the effects of mild traumatic brain injury (mTBI). Previous research focused on sport-related sideline evaluation of adolescents and adults. Our goal was to evaluate performance of the SAC among subjects with and without head injury in a pediatric emergency(More)
Performance on the Medical Symptom Validity Test (MSVT) was examined in 193 consecutively referred patients aged 8 through 17 years who had sustained a mild traumatic brain injury. A total of 33 participants failed to meet actuarial criteria for valid effort on the MSVT. After accounting for possible false positives and false negatives, the base rate of(More)
OBJECTIVE Executive dysfunction after traumatic brain injury (TBI) in children is common and leads to significant problems in functioning across multiple settings. The objective of this study was to evaluate the efficacy of a web-based counselor-assisted problem solving (CAPS) intervention compared with an Internet resource comparison (IRC) for treatment of(More)
In adult populations, research on methodologies to identify negative response bias has grown exponentially in the last two decades. Far less work has focused on methods appropriate for children. Although several recent studies have demonstrated the appropriateness of using stand-alone symptom validity tests with younger populations, a near absence of(More)
This study aimed to characterize preinjury emotional-behavioral functioning in pediatric patients with lingering problems after mild traumatic brain injury (TBI). The clinical case series design included 278 patients 8-17 years old. Parents retrospectively rated children's preinjury emotional-behavioral functioning on a broadband questionnaire. The rate of(More)
A dynamic assessment approach was used to examine the source of poor performance on the Rey-Osterrieth Complex Figure Test (ROCF) among 202 school-age children referred for learning difficulties. The ROCF was administered in the standard format and then in a structured format that highlighted the design's organizational framework. Manipulating encoding in(More)
