The Use of Methylphenidate During Inpatient Rehabilitation After Pediatric Traumatic Brain Injury: Population Characteristics and Prescribing Patterns.

OBJECTIVE: To understand how methylphenidate (MPH) is used in youth with traumatic brain injury (TBI) during inpatient pediatric rehabilitation. SETTING: Inpatient pediatric rehabilitation. PARTICIPANTS: In total, 234 children with TBI; 62 of whom received MPH and 172 who did not. Patients were on average 11.6 years of age (range, 2 months to 21 years); 88 of 234 were female; the most common mechanism of injury was motor vehicle collision (49%); median (IQR) acute hospital length of stay (LOS) and inpatient rehabilitation LOS were 16 (10-29) and 23 (14-39), respectively; 51 of 234 were in a disorder of consciousness cognitive state at time of inpatient rehabilitation admission. DESIGN: Multicenter, retrospective medical record review. MAIN MEASURES: Patient demographic data, time to inpatient pediatric rehabilitation admission (TTA), cognitive state, MPH dosing (mg/kg/day). RESULTS: Patients who received MPH were older (P = .011); TTA was significantly longer in patients who received MPH than those who did not (P =.002). The lowest recorded dose range by weight was 0.05 to 0.89 mg/kg/d, representing an 18-fold difference; the weight-based range for the maximum dose was 0.11 to 0.97 mg/kg/d, a 9-fold difference. Patients in lower cognitive states at admission (P = .001) and at discharge (P = .030) were more likely to receive MPH. Five patients had side effects known to be associated with MPH; no serious adverse events were reported. CONCLUSION: This multicenter study indicates that there is variable use of MPH during acute inpatient rehabilitation for children with TBI. Children who receive MPH tend to be older with lower cognitive states. Dosing practices are likely consistent with underdosing. Clinical indications for MPH use during inpatient pediatric rehabilitation should be better defined. The use of MPH, as well as its combination with other medications and treatments, during inpatient rehabilitation needs to be further explored.

A survey of pediatric neuropsychologists serving inpatient rehabilitation, Part II: billing, time allocation and tracking, and professional identity and perceptions.

Professional challenges have been documented in broad surveys of neuropsychologists. While previous surveyors have included pediatric neuropsychologists, few, if any, have specifically examined practices among those who primarily work in pediatric inpatient rehabilitation settings. Therefore, the aim of this study was to survey neuropsychologists in this setting. Thirty neuropsychologists from the U.S. and one from Canada that work in inpatient pediatric rehabilitation participated in an online survey. Most respondents (83.3%) billed for their inpatient time. Sixty-four percent indicated that payor type (private vs. public) affected services a moderate amount to a lot; this was primarily due to payor's influence on length of stay. Most providers had productivity expectations (66.7%). Among those that had productivity expectations, three-quarters used "hours billed;" 37.5% were solely or additionally tracked by relative value units (RVUs). The majority of respondents conducted some type of clinical data collection, usually for research purposes. With respect to professional identity, most respondents indicated positivity about their role. The top challenges endorsed were related to workload/ability to meet the patients' needs and billing/productivity. Issues related to billing and payor may influence aspects of pediatric inpatient rehabilitation neuropsychological care. Managing challenges related to billing and the time demands associated with providing inpatient services were top concerns for many respondents. Most sites surveyed were involved in data collection, usually for research purposes; increased data collection efforts are needed to aid with program development and evaluation and to demonstrate the added value of neuropsychological services from a patient care perspective.

The role of the Neuropsychologist across the stages of recovery from acquired brain injury: a summary from the pediatric rehabilitation Neuropsychology collaborative.

Neuropsychologists working in a pediatric neurorehabilitation setting provide care for children and adolescents with acquired brain injuries (ABI) and play a vital role on the interdisciplinary treatment team. This role draws on influences from the field of clinical neuropsychology and its pediatric subspecialty, as well as rehabilitation psychology. This combination of specialties is uniquely suited for working with ABI across the continuum of recovery. ABI recovery often involves a changing picture that spans across stages of recovery (e.g., disorders of consciousness, confusional state, acute cognitive impairment), where each stage presents with distinctive characteristics that warrant a specific evidence-based approach. Assessment and intervention are used reciprocally to inform diagnostics, treatment, and academic planning, and to support patient and family adjustment. Neuropsychologists work with the interdisciplinary teams to collect and integrate data related to brain injury recovery and use this data for treatment planning and clinical decision making. These approaches must often be adapted and adjusted in real time as patients recover, demanding a dynamic expertise that is currently not supported through formal training curriculum or practice guidelines. This paper outlines the roles and responsibilities of pediatric rehabilitation neuropsychologists across the stages of ABI recovery with the goal of increasing awareness in order to continue to develop and formalize this role.

Neuropsychological functioning in children and adolescents with anti-NMDA receptor encephalitis (anti-NMDARE).

The objective of this study was to describe neuropsychological functioning and associated medical features in pediatric patients with anti-NMDA receptor encephalitis (anti-NMDARE). Retrospective data were collected from electronic medical records and neuropsychological reports of 15 children and adolescents with cerebral spinal fluid antibody-confirmed anti-NMDARE who were 7-21 years old at the time of the neuropsychological evaluation. The median time between treatment initiation for anti-NMDARE and neuropsychological testing was 228 days (IQR 431, range 41-927). Consistent with the limited literature, this pediatric sample with anti-NMDARE generally had average IQs, but had scores falling in the low average range on tests of verbal and visual memory as well as aspects of executive functioning (set shifting and phonemic verbal fluency). Other relative weaknesses were observed in visuo-constructional ability and reading comprehension. Future prospective studies are needed to replicate these data and explore disease and treatment variables that reduce or exacerbate the risk for neuropsychological sequelae, while longitudinal analyses are required to better characterize academic, vocational, and social outcomes.

Professional stakeholders' perceptions of barriers to behavioral health care following pediatric traumatic brain injury.

OBJECTIVE: To examine professional stakeholders' perspectives of barriers to behavioral health care (BHC) follow-up and telepsychology after pediatric traumatic brain injury (TBI). METHODS: Twenty-nine professionals participated in a focus group (FG) or key informant interview (KII) between January and March 2020. Professionals answered questions about facilitators and barriers to BHC follow-up and telepsychology. Given widespread telepsychology implementation since COVID-19, a follow-up survey assessing telehealth perceptions since the pandemic was sent out in December 2020. Nineteen professionals completed the survey. RESULTS: Professionals identified individual (e.g., family factors, insurance coverage/finances, transportation/distance, availability, planning follow-up care) and system-level (e.g., lack of access to BHC providers) barriers to BHC post-injury. Possible solutions, like collaborative follow-up care, were also identified. Generally, clinical professionals have favorable impressions of telepsychology and utilized services as a delivery modality for clinical care. Though telepsychology could reduce barriers to care, professionals also expressed concerns (e.g., technology issues, security/safety) and challenges (e.g., funding, accessibility, training/licensure for clinicians) with implementing telepsychology. CONCLUSION: Barriers identified highlight the need for context-specific solutions to increase BHC access, with telepsychology generally recognized as a beneficial modality for BHC. Future work should continue to focus on understanding barriers to BHC and potential solutions after pediatric TBI.

Prescribing Patterns of Amantadine During Pediatric Inpatient Rehabilitation After Traumatic Brain Injury: A Multicentered Retrospective Review From the Pediatric Brain Injury Consortium.

OBJECTIVES: To describe dosing practices for amantadine hydrochloride and related adverse effects among children and young adults with traumatic brain injury (TBI) admitted to pediatric inpatient rehabilitation units. SETTING: Eight pediatric acute inpatient rehabilitation units located throughout the United States comprising the Pediatric Brain Injury Consortium. PARTICIPANTS: Two-hundred thirty-four children and young adults aged 2 months to 21 years with TBI. DESIGN: Retrospective data revie. MAIN OUTCOME MEASURES: Demographic variables associated with the use of amantadine, amantadine dose, and reported adverse effects. RESULTS: Forty-nine patients (21%) aged 0.9 to 20 years received amantadine during inpatient rehabilitation. Forty-five percent of patients admitted to inpatient rehabilitation with a disorder of consciousness (DoC) were treated with amantadine, while 14% of children admitted with higher levels of functioning received amantadine. Children with DoC who were not treated with amantadine were younger than those with DoC who received amantadine (median 3.0 vs 11.6 years, P = .008). Recorded doses of amantadine ranged from 0.7 to 13.5 mg/kg/d; the highest total daily dose was 400 mg/d. Adverse effects were reported in 8 patients (16%); nausea/abdominal discomfort and agitation were most common, each reported in 3 patients. The highest reported dose without an adverse effect was 10.1 mg/kg/d. CONCLUSION: During pediatric inpatient rehabilitation, amantadine was prescribed to children across a range of ages and injury severity and was most commonly prescribed to older children with DoC. Dosing varied widely, with weight-based dosing for younger/smaller children at both lower and higher doses than what had been previously reported. Prospective studies are needed to characterize the safety and tolerability of higher amantadine doses and optimize amantadine dosing parameters for children with TBI.

Clinical and training practices: A survey of pediatric neuropsychologists serving inpatient rehabilitation.

Neuropsychologists in inpatient pediatric rehabilitation settings collaborate with an interdisciplinary team to educate, evaluate, and provide intervention to patients with acquired brain injury and their families, but there are no known studies that describe or define these clinical services. Thirty-one neuropsychologists in pediatric inpatient rehabilitation settings completed an online survey. Neuropsychologists (68.2% female; 86.4% with PhD versus PsyD) from the U.S. and Canada, who represented 22 pediatric inpatient rehabilitation sites comprised the final sample. Most sites (63.6%) were embedded within medical centers, with providers dedicating 2 to 32 hours (M = 14.25, SD = 9.26) weekly to onsite inpatient rehabilitation efforts. Providers most often saw patients with traumatic brain injury and other acquired brain injuries, including stroke and brain tumor. Trainees from various levels, most commonly post-doctoral fellows, provided clinical services on inpatient units, many with some degree of independence. Clinical practices that were standard across all or most sites included targeted discharge evaluations, serial cognitive monitoring, neuropsychology consultation to rehabilitation and non-rehabilitation units, and follow-up clinics. Provision of services was influenced by multiple factors including patient diagnosis, timing of return to school, inpatient census, and payor's effect on length of stay. Findings highlight many programmatic consistencies across sites and serve as an important initial step to guiding pediatric neuropsychology providers seeking to understand the current landscape of clinical care. Future efforts are needed to establish a true clinical guideline for practice. Although preliminary, data also support establishment of neuropsychology training programs, justify administrative resources, and serve to educate recipients of neuropsychology services.

Cognitive Recovery During Inpatient Rehabilitation Following Pediatric Traumatic Brain Injury: A Pediatric Brain Injury Consortium Study.

OBJECTIVES: To characterize the demographics, clinical course, and predictors of cognitive recovery among children and young adults receiving inpatient rehabilitation following pediatric traumatic brain injury (TBI). DESIGN: Retrospective observational, multicenter study. SETTING: Eight acute pediatric inpatient rehabilitation facilities in the United States with specialized programs for treating patients with TBI. PARTICIPANTS: Children and young adults (0-21 years) with TBI (n = 234) receiving inpatient rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Admission and discharge status assessed by the WeeFIM Cognitive Developmental Functional Quotient (DFQ) and Cognitive and Linguistic Scale (CALS). RESULTS: Patients admitted to pediatric inpatient rehabilitation are diverse in cognitive functioning. While the majority of patients make improvements, cognitive recovery is constrained for those admitted with the most severe cognitive impairments. Age, time since injury to rehabilitation admission, and admission WeeFIM Cognitive DFQ are significant predictors of cognitive functioning at discharge from inpatient rehabilitation. CONCLUSIONS: This work establishes a multicenter Pediatric Brain Injury Consortium and characterized the demographics and clinical course of cognitive recovery during inpatient rehabilitation of pediatric patients with TBI to aid in prospective study design.

Acute Imaging Findings Predict Recovery of Cognitive and Motor Function after Inpatient Rehabilitation for Pediatric Traumatic Brain Injury: A Pediatric Brain Injury Consortium Study.

Traumatic brain injury (TBI) is a major cause of morbidity and mortality in children; survivors experience long-term cognitive and motor deficits. To date, studies predicting outcome following pediatric TBI have primarily focused on acute behavioral responses and proxy measures of injury severity; unsurprisingly, these measures explain very little of the variance following heterogenous injury. In adults, certain acute imaging biomarkers help predict cognitive and motor recovery following moderate to severe TBI. This multi-center, retrospective study, characterizes the day-of-injury computed tomographic (CT) reports of pediatric, adolescent, and young adult patients (2 months to 21 years old) who received inpatient rehabilitation services for TBI (n = 247). The study also determines the prognostic utility of CT findings for cognitive and motor outcomes assessed by the Pediatric Functional Independence Measure, converted to age-appropriate developmental functional quotient (DFQ), at discharge from rehabilitation. Subdural hematomas (66%), contusions (63%), and subarachnoid hemorrhages (59%) were the most common lesions; the majority of subjects had less severe Rotterdam CT scores (88%, ≤ 3). After controlling for age, gender, mechanism of injury, length of acute hospital stay, and admission DFQ in multivariate regression analyses, the highest Rotterdam score (ß = -25.2, p < 0.01) and complete cisternal effacement (ß = -19.4, p < 0.05) were associated with lower motor DFQ, and intraventricular hemorrhage was associated with lower motor (ß = -3.7, p < 0.05) and cognitive DFQ (ß = -4.9, p < 0.05). These results suggest that direct detection of intracranial injury provides valuable information to aid in prediction of recovery after pediatric TBI, and needs to be accounted for in future studies of prognosis and intervention.

COVID-19 issues related to pediatric neuropsychology and inpatient rehabilitation - challenges to usual care and solutions during the pandemic.

Objective: To describe the challenges related to COVID-19 affecting pediatric neuropsychologists practicing in inpatient brain injury rehabilitation settings, and offer solutions focused on face-to-face care and telehealth.Methods: A group of pediatric neuropsychologists from 12 pediatric rehabilitation units in North America and 2 in South America have met regularly since COVID-19 stay-at-home orders were initiated in many parts of the world. This group discussed challenges to clinical care and collaboratively problem-solvedsolutions.Results: Three primary challenges to usual care were identified, these include difficulty providing 1) neurobehavioral and cognitive assessments; 2) psychoeducation for caregivers and rapport building; and 3) return to academic instruction and home. Solutions during the pandemic for the first two areas focus on the varying service provision models that include 1) face-to-face care with personal protective equipment (PPE) and social distancing and 2) provision of care via remote methods, with a focus on telehealth. During the pandemic,neuropsychologists generally combine components of both the face-to-face and remote care models. Solutions to the final challenge focus on issues specific to returning to academic instruction and home after an inpatient stay.Conclusions: By considering components of in-person and telehealth models of patient care during the pandemic, neuropsychologists successfully serve patients within the rehabilitation setting, as well as the patient's family who may be limited in their ability to be physically present due to childcare, illness, work-related demands, or hospital restrictions.

A Survivor's Journey: Preliminary efficacy of an online problem-solving therapy for survivors of pediatric brain tumor.

BACKGROUND: Although pediatric brain tumor survivors are at high risk for a variety of psychosocial and neurocognitive late effects, there are few evidence-based interventions to address their needs. The purpose of this study was to test the efficacy of an online problem-solving intervention on improving the quality of life and executive dysfunction among adolescent and young adult brain tumor survivors. PROCEDURE: A Survivor's Journey was adapted from a similar intervention for survivors of traumatic brain injuries, and involved self-guided web modules providing training in problem-solving as a tool for coping with everyday challenges, as well as weekly teleconferences with a trained therapist. Survivors (n = 19) between the ages of 13 and 25, and their caregivers, completed standardized measures of their emotional and behavioral functioning, executive functioning, and quality of life before and after the 12- to 16-week intervention. RESULTS: Participation in the intervention led to significant improvements in self-reported overall (Mpre  = 62.03, SDpre  = 17.67, Mpost  = 71.97, SDpost  = 16.75; d = 0.58, P = 0.01) and physical quality of life (Mpre  = 63.13, SDpre  = 21.88, Mpost  = 75.00, SDpost  = 21.33; d = 0.55, P < 0.01) as well as parent-reported emotional quality of life (Mpre  = 65.00, SDpre  = 28.72, Mpost  = 76.15, SDpost  = 23.47; d = 0.43, P = 0.03). Greater improvement was noted in those who were diagnosed before the age of seven and those with average or above average estimated IQs. Current age did not moderate outcomes. CONCLUSIONS: Online problem-solving therapy may be efficacious in improving pediatric brain tumor survivors' quality of life; however, further research with a comparison group is needed. Online interventions such as Survivor's Journey may decrease barriers to evidence-based psychosocial care for brain tumor survivors.

Evolution of parental knowledge and efficacy across the pediatric neuropsychological evaluation process.

OBJECTIVE: The handful of studies examining parent satisfaction after pediatric neuropsychological evaluations have focused on post-evaluation appraisals. By examining parent experiences across the course of their child's evaluation, this study aimed to provide important insights into how and when parents experience changes in knowledge, understanding of care options, and efficacy during evaluation process. METHOD: Parents of youth receiving neuropsychological evaluation completed questionnaires at four time points (prior to evaluation [n = 363], day of testing [n = 300], prior to feedback [n = 250], and post-report [n = 99]). Parents rated aspects of their knowledge and efficacy regarding their child's functioning. Parents also rated their perception of the neuropsychologist, medical provider, and school along the same domains. The resulting longitudinal data were analyzed using structural equation modeling and ANCOVA. Although primary analyses focused on the entire sample, differences between first-time evaluations and re-evaluations were also examined. RESULTS: Families receiving an initial evaluation showed lower ratings in knowledge, awareness of options, and efficacy at the beginning of the evaluation and a significant increase in ratings by the end of the evaluation. Families returning for re-evaluation showed higher initial ratings that changed comparatively little during the evaluation. Parents receiving initial evaluations also perceived increased knowledge of their child by medical providers and school. CONCLUSION: The study supports the clinical assumption that parents gain knowledge about their child and treatment options during a neuropsychological evaluation. The difference between initial and re-evaluation warrants further study. Studying the process and experience of neuropsychological evaluation may provide more nuanced findings than post hoc satisfaction measures.

Development of a Web-Based Psychosocial Intervention for Adolescent and Young Adult Survivors of Pediatric Brain Tumor.

PURPOSE: To develop A Survivor's Journey, a web-based psychosocial intervention for adolescent and young adult (AYA) survivors of pediatric brain tumors (PBTs). METHODS: Stages of development included focus groups with five AYA survivors (ages 16-23 years) and six parents to identify needs and challenges, as well as surveys and interviews with clinical care providers at a survivorship clinic. RESULTS: Concerns reported by AYA survivors, parents, and providers were similar to those reported in the literature, including fatigue, memory deficits, poor mood, health concerns, and challenging peer relationships. However, concerns varied across survivors, underscoring the need for customizable interventions. Survivors and parents were interested in an intervention targeting psychosocial functioning and late effects, and reported a strong preference for web-based interventions that would reduce cost and travel burden on the family. INTERVENTION: Based on review of the literature, survivor and parent feedback, as well as provider input, a customizable intervention, A Survivor's Journey, was developed consisting of five core sessions (addressing concerns common to AYA survivors such as memory, staying positive, and problem solving) and up to seven supplemental sessions (addressing variable needs of survivors such as managing fatigue, inattention, planning/organization, communication/relationships, and self-care). CONCLUSION: Despite growing recognition of long-term challenges and late effects, there are few interventions targeting psychosocial well-being of AYA survivors. If efficacious, A Survivor's Journey will be an accessible and cost-effective intervention to improve psychosocial functioning of AYA survivors of PBT.

Communication is key: the utility of a revised neuropsychological report format.

OBJECTIVE: The neuropsychological report is a critical tool for communicating evaluation results to multiple audiences who have varying knowledge about neuropsychology and often have limited ability to review long, complex reports. Considerable time is spent writing these reports and challenges persist related to readability, length/complexity, and billable clinical time (which may be capped by third-party payors or families' ability to pay). METHODS: This quality improvement effort systematically evaluated the redesign of pediatric neuropsychological reports in an outpatient clinic serving primarily medical populations. RESULTS: Revised reports were shorter, with improved readability, structure, and effectiveness in communicating results and recommendations. Improved clinical efficiency was also observed. CONCLUSIONS: We suggest that adaptation to efficient, readable, and effective reports is possible within the practice of neuropsychology. Findings encourage replication in other settings. Through collaboration with key stakeholders, providers can identify their populations' and audience's unique needs and set report targets accordingly. To encourage that practice, we summarize our general process, provide a set of guidelines that can be adapted across multiple settings, and include an appended sample report.

Implementing guidelines: Proposed definitions of neuropsychology services in pediatric oncology.

Several organizations have published guidelines for the neuropsychological care of survivors of childhood cancer. However, there is limited consensus in how these guidelines are applied. The model of neuropsychology service delivery is further complicated by the variable terminology used to describe recommended services. In an important first step to translate published guidelines into clinical practice, this paper proposes definitions for specific neuropsychological processes and services, with the goal of facilitating consistency across sites to foster future clinical program development and to clarify clinical practice guidelines.

A comparison of WISC-IV and SB-5 intelligence scores in adolescents with autism spectrum disorder.

In autism spectrum disorders, results of cognitive testing inform clinical care, theories of neurodevelopment, and research design. The Wechsler Intelligence Scale for Children and the Stanford-Binet are commonly used in autism spectrum disorder evaluations and scores from these tests have been shown to be highly correlated in typically developing populations. However, they have not been compared in individuals with autism spectrum disorder, whose core symptoms can make testing challenging, potentially compromising test reliability. We used a within-subjects research design to evaluate the convergent validity between the Wechsler Intelligence Scale for Children, 4th ed., and Stanford-Binet, 5th ed., in 40 youth (ages 10-16 years) with autism spectrum disorder. Corresponding intelligence scores were highly correlated (r = 0.78 to 0.88), but full-scale intelligence quotient (IQ) scores (t(38) = -2.27, p = 0.03, d = -0.16) and verbal IQ scores (t(36) = 2.23, p = 0.03; d = 0.19) differed between the two tests. Most participants obtained higher full-scale IQ scores on the Stanford-Binet, 5th ed., compared to Wechsler Intelligence Scale for Children, 4th ed., with 14% scoring more than one standard deviation higher. In contrast, verbal indices were higher on the Wechsler Intelligence Scale for Children, 4th ed., Verbal-nonverbal discrepancy classifications were only consistent for 60% of the sample. Comparisons of IQ test scores in autism spectrum disorder and other special groups are important, as it cannot necessarily be assumed that convergent validity findings in typically developing children and adolescents hold true across all pediatric populations.

Development, validation, and utility of an instrument to assess core competencies in the Leadership Education in Neurodevelopmental and Related Disabilities (LEND) program.

To describe the development and psychometric evaluation of the Core Competency Measure (CCM), an instrument designed to assess professional competencies as defined by the Maternal Child Health Bureau (MCHB) and targeted by Leadership Education in Neurodevelopmental and Related Disabilities (LEND) programs. The CCM is a 44-item self-report measure comprised of six subscales to assess clinical, interdisciplinary, family-centered/cultural, community, research, and advocacy/policy competencies. The CCM was developed in an iterative fashion through participatory action research, and then nine cohorts of LEND trainees (N = 144) from 14 different disciplines completed the CCM during the first week of the training program. A 6-factor confirmatory factor analysis model was fit to data from the 44 original items. After three items were removed, the model adequately fit the data (comparative fit indices = .93, root mean error of approximation = .06) with all factor loadings exceeding .55. The measure was determined to be quite reliable as adequate internal consistency and test-retest reliability were found for each subscale. The instrument's construct validity was supported by expected differences in self-rated competencies among fellows representing various disciplines, and the convergent validity was supported by the pattern of inter-correlations between subscale scores. The CCM appears to be a reliable and valid measure of MCHB core competencies for our sample of LEND trainees. It provides an assessment of key training areas addressed by the LEND program. Although the measure was developed within only one LEND Program, with additional research it has the potential to serve as a standardized tool to evaluate the strengths and limitations of MCHB training, both within and between programs.

Sleep restriction worsens mood and emotion regulation in adolescents.

BACKGROUND: The relationship between inadequate sleep and mood has been well-established in adults and is supported primarily by correlational data in younger populations. Given that adolescents often experience shortened sleep on school nights, we sought to better understand the effect of experimentally induced chronic sleep restriction on adolescents' mood and mood regulation. METHODS: Fifty healthy adolescents, ages 14-17, completed a 3-week sleep manipulation protocol involving a baseline week, followed by a sleep restriction (SR) condition (6.5 hr in bed per night for five nights) and healthy sleep duration (HS) condition (10 hr in bed per night for five nights). The study used a randomized, counterbalanced, crossover experimental design. Participants' sleep was monitored at home via self-report and actigraphy. At the end of each condition, participants and their parents completed questionnaires of mood and mood regulation. To assess for expectancy effects, we also analyzed parent and teen ratings of hyperactivity/impulsivity, which prior research suggests is not sensitive to SR in adolescents. Wilcoxon Signed Rank tests compared questionnaire outcomes across the two conditions. RESULTS: Participants averaged 2.5 more hours of sleep per night during HS relative to SR. Compared with HS, adolescents rated themselves as significantly more tense/anxious, angry/hostile, confused, and fatigued, and as less vigorous (p = .001-.01) during SR. Parents and adolescents also reported greater oppositionality/irritability and poorer emotional regulation during SR compared with HS (p < .05). There were no cross-condition differences in depression or hyperactivity/impulsivity (p > .05). CONCLUSIONS: Findings complement prior correlational study results to show that after only a few days of shortened sleep, at a level of severity that is experienced regularly by millions of adolescents on school nights, adolescents have worsened mood and decreased ability to regulate negative emotions.

The effect of temperament and neuropsychological functioning on behavior problems in children with new-onset seizures.

The present study is part of a larger project that seeks to identify factors that predict children's behavioral, social, and cognitive adaptation to epilepsy. Children with seizures are more likely to have internalizing and externalizing behavior problems than either healthy children or children with other chronic illnesses. The present research examines risk factors for behavior problems. Early temperament and neuropsychological functioning, specifically executive function and language abilities, are evaluated as unique and moderating predictors of adverse behavioral outcomes in 229 children with a first recognized seizure. Parents assessed temperament, children were administered neuropsychological tests, and teachers evaluated behavior 36 months after seizure onset. Results revealed that early temperament and neuropsychological functioning, specifically executive function, predicted behavioral outcomes 3 years after seizure onset.

Temperament, family environment, and behavior problems in children with new-onset seizures.

Children with epilepsy, even those with new-onset seizures, exhibit relatively high rates of behavior problems. The purpose of this study was to explore the relationships among early temperament, family adaptive resources, and behavior problems in children with new-onset seizures. Our major goal was to test whether family adaptive resources moderated the relationship between early temperament dimensions and current behavior problems in 287 children with new-onset seizures. Two of the three temperament dimensions (difficultness and resistance to control) were positively correlated with total, internalizing, and externalizing behavior problems (all P<0.0001). The third temperament dimension, unadaptability, was positively correlated with total and internalizing problems (P<0.01). Family adaptive resources moderated the relationships between temperament and internalizing and externalizing behavior problems at school. Children with a difficult early temperament who live in a family environment with low family mastery are at the greatest risk for behavior problems.
