Trial of Training to Reduce Driver Inattention in Teens with ADHD.

BACKGROUND: Teens with attention deficit-hyperactivity disorder (ADHD) are at increased risk for motor vehicle collisions. A computerized skills-training program to reduce long glances away from the roadway, a contributor to collision risk, may ameliorate driving risks among teens with ADHD. METHODS: We evaluated a computerized skills-training program designed to reduce long glances (lasting ≥2 seconds) away from the roadway in drivers 16 to 19 years of age with ADHD. Participants were randomly assigned in a 1:1 ratio to undergo either enhanced Focused Concentration and Attention Learning, a program that targets reduction in the number of long glances (intervention) or enhanced conventional driver's education (control). The primary outcomes were the number of long glances away from the roadway and the standard deviation of lane position, a measure of lateral movements away from the center of the lane, during two 15-minute simulated drives at baseline and at 1 month and 6 months after training. Secondary outcomes were the rates of long glances and collisions or near-collisions involving abrupt changes in vehicle momentum (g-force event), as assessed with in-vehicle recordings over the 1-year period after training. RESULTS: During simulated driving after training, participants in the intervention group had a mean of 16.5 long glances per drive at 1 month and 15.7 long glances per drive at 6 months, as compared with 28.0 and 27.0 long glances, respectively, in the control group (incidence rate ratio at 1 month, 0.64; 95% confidence interval [CI], 0.52 to 0.76; P<0.001; incidence rate ratio at 6 months, 0.64; 95% CI, 0.52 to 0.76; P<0.001). The standard deviation of lane position (in feet) was 0.98 SD at 1 month and 0.98 SD at 6 months in the intervention group, as compared with 1.20 SD and 1.20 SD, respectively, in the control group (difference at 1 month, -0.21 SD; 95% CI, -0.29 to -0.13; difference at 6 months, -0.22 SD; 95% CI, -0.31 to -0.13; P<0.001 for interaction for both comparisons). During real-world driving over the year after training, the rate of long glances per g-force event was 18.3% in the intervention group and 23.9% in the control group (relative risk, 0.76; 95% CI, 0.61 to 0.92); the rate of collision or near-collision per g-force event was 3.4% and 5.6%, respectively (relative risk, 0.60, 95% CI, 0.41 to 0.89). CONCLUSIONS: In teens with ADHD, a specially designed computerized simulated-driving program with feedback to reduce long glances away from the roadway reduced the frequency of long glances and lessened variation in lane position as compared with a control program. During real-world driving in the year after training, the rate of collisions and near-collisions was lower in the intervention group.

A Multi-Method Examination of Peer Functioning in Children with and without Cognitive Disengagement Syndrome.

OBJECTIVE: Cognitive disengagement syndrome (CDS) includes excessive daydreaming, mental confusion, and hypoactive behaviors that are distinct from attention-deficit/hyperactivity disorder inattentive (ADHD-IN) symptoms. A growing number of studies indicate that CDS symptoms may be associated with ratings of social withdrawal. However, it is important to examine this association in children specifically recruited for the presence or absence of CDS, and to incorporate multiple methods including direct observations of peer interactions. The current study builds on previous research by recruiting children with and without clinically elevated CDS symptoms and using a multi-method, multi-informant design including recess observations and parent, teacher, and child rating scales. METHOD: Participants were 207 children in grades 2-5 (63.3% male), including 103 with CDS and 104 without CDS, closely matched on grade and sex. RESULTS: Controlling for family income, medication status, internalizing symptoms, and ADHD-IN severity, children with CDS were observed during recess to spend more time alone or engaging in parallel play, as well as less time involved in direct social interactions, than children without CDS. Children with CDS were also rated by teachers as being more asocial, shy, and socially disinterested than children without CDS. Although children with and without CDS did not differ on parent- or self-report ratings of shyness or social disinterest, children with CDS rated themselves as lonelier than children without CDS. CONCLUSIONS: Findings indicate that children with CDS have a distinct profile of peer functioning and point to the potential importance of targeting withdrawal in interventions for youth with elevated CDS symptoms.

Examining daily stimulant medication use and sleep in adolescents with ADHD.

Research has been inconclusive as to whether stimulant treatment causes or exacerbates sleep problems in adolescents with ADHD. This study examined sleep differences in adolescents with ADHD as a function of stimulant use. Participants were adolescents with ADHD (N = 159, ages 12-14). Parents reported on receipt of stimulant treatment (n = 92, 57.86%; n = 47 amphetamines, n = 45 methylphenidate). Adolescents wore actigraphs and completed daily diaries assessing sleep and daily use of stimulants for 2 weeks. Sleep parameters included daily-reported bedtime, sleep onset latency (SOL), sleep duration, daytime sleepiness, and difficulty waking the following morning; and actigraphy-measured sleep onset time, total time in bed, and sleep efficiency. We estimated between- and within-individual associations between stimulant medication use and sleep indices with all stimulants, after removing adolescents using sleep aids and weekend days, and as a function of stimulant type. Adolescent sleep did not differ between those receiving and not receiving stimulant treatment. Within individuals using stimulants, we largely observed no significant differences between medicated and unmedicated days, though findings were most often significant for school days only. Small effects were found indicating longer SOL, later sleep onset time, and more daytime sleepiness related to medication use. In contrast, there were slight improvements to sleep duration and sleep efficiency related to methylphenidate use, though methylphenidate was also associated with later sleep onset time and more daytime sleepiness. Given the inconsistent and small effects, findings suggest that stimulant medication may impact sleep, but does not appear to be a primary contributor to sleep problems in adolescents with ADHD.

Examining Patterns and Predictors of ADHD Teens' Skill-Learning Trajectories During Enhanced FOrward Concentration and Attention Learning (FOCAL+) Training.

OBJECTIVE: Examine patterns and predictors of skill learning during multisession Enhanced FOrward Concentration and Attention Learning (FOCAL+) training. BACKGROUND: FOCAL+ teaches teens to reduce the duration of off-road glances using real-time error learning. In a randomized controlled trial, teens with ADHD received five sessions of FOCAL+ training and demonstrated significant reductions in extended glances (>2-s) away from the roadway (i.e., long-glances) and a 40% reduced risk of a crash/near-crash event. Teens' improvement in limiting long-glances as assessed after each FOCAL+ training session has not been examined. METHOD: Licensed teen (ages 16-19) drivers with ADHD (n = 152) were randomly assigned to five sessions of either FOCAL+ or modified standard driver training. Teens completed driving simulation assessments at baseline, after each training session, and 1 month and 6 months posttraining. Naturalistic driving was monitored for one year. RESULTS: FOCAL+ training produced a 53% maximal reduction in long-glances during postsession simulated driving. The number of sessions needed to achieve maximum performance varied across participants. However, after five FOCAL+ training sessions, number of long-glances was comparable irrespective of when teens achieved their maximum performance. The magnitude of reduction in long-glances predicted levels of long-glances during simulated driving at 1 month and 6 months posttraining but not naturalistic driving outcomes. FOCAL+ training provided the most benefit during training to teens who were younger and had less driving experience. CONCLUSION: FOCAL+ training significantly reduces long-glances beginning at the 1st training session. APPLICATION: Providing five FOCAL+ training sessions early on during teen driving may maximize benefit.

The Effects of Attention-Deficit/Hyperactivity Disorder Symptoms on the Association between Head Impacts and Post-Season Neurocognitive and Behavioral Outcomes.

OBJECTIVE: Having attention-deficit/hyperactivity disorder (ADHD) is a risk factor for concussion that impacts concussion diagnosis and recovery. The relationship between ADHD and repetitive subconcussive head impacts on neurocognitive and behavioral outcomes is less well known. This study evaluated the role of ADHD as a moderator of the association between repetitive head impacts on neurocognitive test performance and behavioral concussion symptoms over the course of an athletic season. METHOD: Study participants included 284 male athletes aged 13-18 years who participated in high school football. Parents completed the Strengths and Weaknesses of ADHD Symptoms and Normal Behavior (SWAN) ratings about their teen athlete before the season began. Head impacts were measured using an accelerometer worn during all practices and games. Athletes and parents completed behavioral ratings of concussion symptoms and the Attention Network Task (ANT), Digital Trail Making Task (dTMT), and Cued Task Switching Task at pre- and post-season. RESULTS: Mixed model analyses indicated that neither head impacts nor ADHD symptoms were associated with post-season athlete- or parent-reported concussion symptom ratings or neurocognitive task performance. Moreover, no relationships between head impact exposure and neurocognitive or behavioral outcomes emerged when severity of pre-season ADHD symptoms was included as a moderator. CONCLUSION: Athletes' pre-season ADHD symptoms do not appear to influence behavioral or neurocognitive outcomes following a single season of competitive football competition. Results are interpreted in light of several study limitations (e.g., single season, assessment of constructs) that may have impacted this study's pattern of largely null results.

Biopsychosocial treatment response among youth with continuous headache: A retrospective, clinic-based study.

BACKGROUND: Youth with continuous (always present) headache are vastly understudied; much remains to be understood regarding treatment response in this population. OBJECTIVE: To describe and explore biopsychosocial factors related to initial clinical outcomes among treatment-seeking youth with continuous headache. METHODS: This retrospective cohort study extracted data of 782 pediatric patients (i.e., aged <18 years) with continuous headache from a large clinical repository. Youth in this study had experienced continuous headache for ≥1 month before presenting to a multidisciplinary headache specialty clinic appointment. Extracted data from this appointment included patients' headache history, clinical diagnoses, and headache-related disability, as well as information about biopsychosocial factors implicated in headache management and/or maintenance (e.g., healthy lifestyle habits, history of feeling anxious or depressed). Additional data regarding patient headache characteristics, disability, and lifestyle habits were extracted from a subset of 529 youth who returned to clinic 4-16 weeks after their initial follow-up visit. After characterizing initial treatment response, exploratory analyses compared youth with the best and worst treatment outcomes on several potentially influential factors. RESULTS: Approximately half of youth (280/526; 53.2%) continued to have continuous headache at follow-up, ~20% of youth (51/526) reported a significant (≥50%) reduction in headache frequency. Improvements in average headache severity (e.g., percentage with severe headaches at initial visit: 45.3% [354/771]; percentage with severe headaches at follow-up visit: 29.8% [156/524]) and headache-related disability were also observed (e.g., percentage severe disability at initial visit: 62.9% [490/779]; percentage severe disability at initial follow-up visit: 34.2% [181/529]). Individuals with the worst headache frequency and disability had a longer history of continuous headache (mean difference estimate = 5.76, p = 0.013) and worse initial disability than the best responders (χ2 [3, 264] = 23.49, p < 0.001). They were also more likely to have new daily persistent headache (χ2 [2, 264] = 12.61, p = 0.002), and were more likely to endorse feeling depressed (χ2 [1, 260] = 11.46, p < 0.001). CONCLUSION: A notable percentage of youth with continuous headache show initial improvements in headache status. Prospective, longitudinal research is needed to rigorously examine factors associated with continuous headache treatment response.

Impact of preventive pill-based treatment on migraine days: A secondary outcome study of the Childhood and Adolescent Migraine Prevention (CHAMP) trial and a comparison of self-report to nosology-derived assessments.

OBJECTIVE: To examine group differences in self-reported migraine days among youth who completed the Childhood and Adolescent Migraine Prevention (CHAMP) trial prior to its closure and explore the relationship between self-reported and "nosology-derived" (i.e., International Classification of Headache Disorders, 3rd edition [ICHD-3]) migraine days. BACKGROUND: The CHAMP trial compared amitriptyline and topiramate to placebo for migraine prevention in youth and proposed to analyze change in migraine days as a secondary outcome. There is considerable variability in the field regarding what constitutes a "migraine day," how this is determined and reported in trials, and how consistent these measures are with diagnostic nosology. METHODS: CHAMP trial completers (N = 175) were randomized to receive amitriptyline (n = 77), topiramate (n = 63), or placebo (n = 35). Participants maintained daily headache diaries where they reported each day with headache and if they considered that headache to be a migraine. For each headache day, participants completed a symptom record and reported about symptoms such as pain location(s) and presence of nausea/vomiting or photophobia and phonophobia. We examined group differences in self-reported migraine days at trial completion (summed from trial weeks 20-24) compared to baseline. We also used an algorithm to determine whether participants' symptom reports met ICHD-3 criteria for migraine without aura, and examined the association between self-reported and "nosology-derived" migraine days. RESULTS: Results showed no significant differences between groups in self-reported migraine days over the course of the trial. Self-reported and "nosology-derived" migraine days during the baseline and treatment phases were strongly associated (r's = 0.73 and 0.83, respectively; p's < 0.001). CONCLUSION: Regardless of treatment, CHAMP trial completers showed clinically important reductions in self-reported migraine days over the course of the trial (about 3.8 days less). The strong association between self-reported and "nosology-derived" migraine days suggests youth with migraine can recognize a day with migraine and reliably report their headache features and symptoms. Greater rigor and transparency in the calculation and reporting of migraine days in trials is needed.

Trajectory of treatment response in the child and adolescent migraine prevention (CHAMP) study: A randomized clinical trial.

OBJECTIVE: Identify preventive medication treatment response trajectories among youth participating in the Childhood and Adolescent Migraine Prevention study. METHODS: Data were evaluated from 328 youth (ages 8-17). Childhood and Adolescent Migraine Prevention study participants completed headache diaries during a 28-day baseline period and a 168-day active treatment period during which youth took amitriptyline, topiramate, or placebo. Daily headache occurrence trajectories were established across baseline and active treatment periods using longitudinal hierarchical linear modeling. We tested potential treatment group differences. We also compared final models to trajectory findings from a clinical trial of cognitive behavioral therapy plus amitriptyline for youth with chronic migraine to test for reproducibility. RESULTS: Daily headache occurrence showed stability across baseline. Active treatment models revealed decreases in headache frequency that were most notable early in the trial period. Baseline and active treatment models did not differ by treatment group and replicated trajectory cognitive behavioral therapy plus amitriptyline trial findings. CONCLUSIONS: Replicating headache frequency trajectories across clinical trials provides strong evidence that youth can improve quickly. Given no effect for medication, we need to better understand what drives this clinically meaningful improvement. Results also suggest an expected trajectory of treatment response for use in designing and determining endpoints for future clinical trials.Trial Registration.

New insight into the neural mechanisms of migraine in adolescents: Relationships with sleep.

OBJECTIVE: This case-control study examines if measures of subjective and objective (actigraphic) sleep difficulties mediate alterations in amygdalar connectivity in adolescents with migraine compared to healthy adolescents. BACKGROUND: Adolescents with migraine have different functional connectivity of the amygdala compared to individuals without migraine. Sleep is often disturbed in adolescents with migraine, and could contribute to the alterations in functional connectivity. METHODS: Twenty adolescents with migraine and 20 healthy controls were recruited from Cincinnati Children's Hospital. Participants completed surveys about their headaches and overall sleep quality, sleep hygiene, and perceived sleep difficulties (Insomnia Severity Scale [ISI]); completed wrist-worn actigraphy; and underwent a magnetic resonance imaging scan. RESULTS: Adolescents with migraine differed from healthy controls only in perceived difficulty in sleep initiation and maintenance (ISI: 8.5 ± 4.7 and 4.5 ± 3.7 [mean ± standard deviation], -4.00 [95% confidence: -6.7 to -1.3], p = 0.005) and had greater functional connectivity between the amygdala and the posterior cingulate cortex, precuneus, dorsolateral prefrontal, sensorimotor, and the occipital cortexes. The differences in functional connectivity of the amygdala were not mediated by the subjective/objective sleep measures (ISI/wake minutes after sleep onset). CONCLUSIONS: Adolescents with migraine have greater connectivity between the amygdala and areas involved in sensory, affective, and cognitive aspects of pain. These alterations may not be due to higher levels of sleep difficulties in adolescents with migraine, suggesting that both amygdala and sleep alterations may play an independent role in migraine pathophysiology. This advances the understanding of the mechanisms underlying pediatric migraine and can potentially advance migraine management.

Multimodal Assessment of Medication Adherence Among Youth With Migraine: An Ancillary Study of the CHAMP Trial.

OBJECTIVE: Examine preventive medication adherence among youth with migraine. METHODS: Adherence (self-report, pill count, and blood serum drug levels) was assessed as an ancillary study that utilized data from 328 CHAMP Study participants (ages 8-17). CHAMP was a multisite trial of preventive medications. Participants completed a prospective headache diary during a six-month active treatment period during which youth took amitriptyline, topiramate, or placebo pill twice daily. Self-reported medication adherence was collected via daily diary. At monthly study visits, pill count measures were captured. At trial month 3 (trial midpoint) and 6 (end of active trial), blood serum drug levels were obtained. Self-report and pill count adherence percentages were calculated for the active trial period, at each monthly study visit, and in the days prior to participants' mid-trial blood draw. Percentages of nonzero drug levels were calculated to assess blood serum drug level data. Adherence measures were compared and assessed in context of several sociodemographic factors. Multiple regression analyses investigated medication adherence as a predictor of headache outcomes. RESULTS: Self-report and pill count adherence rates were high (over 90%) and sustained over the course of the trial period. Serum drug level adherence rates were somewhat lower and decreased significantly (from 84% to 76%) across the trial period [t (198) = 3.23, p = .001]. Adherence measures did not predict headache days at trial end; trial midpoint serum drug levels predicted headache-related disability. CONCLUSIONS: Youth with migraine can demonstrate and sustain relatively high levels of medication adherence over the course of a clinical trial.

Cognitive Behavior Therapy Tailored to Anxiety Symptoms Improves Pediatric Functional Abdominal Pain Outcomes: A Randomized Clinical Trial.

OBJECTIVES: To evaluate the feasibility of a stepped care model, and establish the effect of a tailored cognitive behavioral therapy, the Aim to Decrease Anxiety and Pain Treatment (ADAPT), compared with standard medical treatment as usual on pain-related outcomes and anxiety. STUDY DESIGN: Eligible patients between the ages of 9 and 14 years with functional abdominal pain disorders (n = 139) received enhanced usual care during their medical visit to a gastroenterologist. Those that failed to respond to enhanced usual care were randomized to receive either a tailored cognitive behavioral therapy (ADAPT) plus medical treatment as usual, or medical treatment as usual only. ADAPT dose (4 sessions of pain management or 6 sessions of pain and anxiety management) was based on presence of clinically significant anxiety. Outcomes included feasibility, based on recruitment and retention rates. Response to ADAPT plus medical treatment as usual vs medical treatment as usual on pain-related outcomes and anxiety measures was also investigated using a structural equation modeling equivalent of a MANCOVA. Anxiety levels and ADAPT dose as moderators of treatment effects were also explored. RESULTS: Based on recruitment and retention rates, stepped care was feasible. Enhanced usual care was effective for only 8% of youth. Participants randomized to ADAPT plus medical treatment as usual showed significantly greater improvements in pain-related disability, but not pain levels, and greater improvements in anxiety symptoms compared with those randomized to medical treatment as usual only. Anxiety and ADAPT treatment dose did not moderate the effect of treatment on disability nor pain. CONCLUSIONS: Tailoring care based on patient need may be optimal for maximizing the use of limited psychotherapeutic resources while enhancing care.

Spatial aspects of pain modulation are not disrupted in adolescents with migraine.

OBJECTIVE: To compare spatial pain modulation capabilities between adolescents with and without migraine. BACKGROUND: Conditioned pain modulation (CPM) responses at the leg are similar in adolescents with versus without migraine. However, the anatomical region of testing may affect spatial pain modulation capabilities as differences in nociceptive processing between patients with migraine and healthy controls are found in local areas that are near the site of clinical pain but not in nonlocal areas. This study aimed to examine spatial pain modulation capabilities tested by the CPM paradigm using test stimulus applied to a local body area. METHODS: Nineteen adolescents with migraine (age 14.9 ± 2.3, mean ± SD; 16 female) and 20 healthy adolescents (age 13.8 ± 2.5, mean ± SD; 16 female) completed this case-control study at Cincinnati Children's Hospital Medical Center. Pressure pain thresholds (PPT) were assessed at the trapezius before and during immersion of the foot in a cold water bath (8°C). RESULTS: In the migraine group (146.0 ± 79.1, mean ± SD), compared to healthy controls (248.0 ± 145.5, mean ± SD), significantly lower PPT (kilopascal) values were found (estimate = 124.28, 95% CI: 58.98, 189.59, p < 0.001; effect size: d = 1.40). No differences between the groups were found for pain intensity and unpleasantness ratings of cold-water immersion nor the CPM response. CONCLUSIONS: This study found altered ascending nociceptive processing of mechanical stimuli at the neck in adolescents with migraine. However, endogenous pain modulatory mechanisms were functional and not altered. In light of other studies, impairments in inhibitory control may not be involved in migraine pathophysiology in pediatric patients regardless of stimulus location.

A Longitudinal Assessment of Parenting Stress in Parents of Children with New-Onset Epilepsy.

OBJECTIVE: Parents of children with newly diagnosed epilepsy may experience elevated parenting stress. The present study examined trajectories of parenting stress over time and identified modifiable predictors of these trajectories. METHODS: Parents of youth with epilepsy (N = 102; 2-12 years old) completed questionnaires 1, 4, 13, 19, and 25-months post-diagnosis, including measures of parenting stress, family functioning, child psychosocial functioning, sociodemographics, and perceived stigma. Latent growth curve models (LGCM) were used to examine domains of parenting stress over time. RESULTS: At baseline, 25-48% of parents reported elevated parenting stress. LGCMs revealed that the parent and child domains of parenting stress were generally stable across time. However, life stress was more variable across time, and parents with higher initial life stress had a greater reduction in life stress over time. Socioeconomic status was identified as a non-modifiable predictor of life stress. Family functioning was associated with greater parenting stress in the parent domain. Child psychosocial functioning was associated with greater parenting stress in the parent and child domains. CONCLUSIONS: Parenting stress was elevated for a subset of families and appeared to be relatively stable over time, with the exception of life stress, which was more variable. With early screening, child factors and parent appraisals of epilepsy may be valuable targets for clinical intervention with families of children with epilepsy.

Relationship Between Caregiver Uncertainty, Problem-Solving, and Psychological Adjustment in Pediatric Cancer.

OBJECTIVE: The current study examined the roles of constructive and dysfunctional problem-solving strategies in the relationships between illness uncertainty and adjustment outcomes (i.e., anxious, depressive, and posttraumatic stress symptoms) in caregivers of children newly diagnosed with cancer. METHODS: Two hundred thirty-eight caregivers of children (0-19 years of age) newly diagnosed with cancer (2-14 weeks since diagnosis) completed measures of illness uncertainty, problem-solving strategies, and symptoms of anxiety, depression, and posttraumatic stress. RESULTS: A mediation model path analysis assessed constructive and dysfunctional problem-solving strategies as mediators between illness uncertainty and caregiver anxious, depressive, and posttraumatic stress symptoms. Dysfunctional problem-solving scores partially mediated the relationships between illness uncertainty and anxious, depressive, and posttraumatic stress symptoms. Constructive problem-solving scores did not mediate these relationships. CONCLUSIONS: The current findings suggest that illness uncertainty and dysfunctional problem-solving strategies, but not constructive problem-solving strategies, may play a key role in the adjustment of caregivers of children newly diagnosed with cancer. Interventions aimed at managing illness uncertainty and mitigating the impact of dysfunctional problem-solving strategies may promote psychological adjustment.

Improving self-management in adolescents with sickle cell disease.

BACKGROUND: Sickle cell disease (SCD) is associated with significant medical challenges that often worsen in adolescence when caregivers are beginning to transfer responsibility for disease management. Behavioral activation (BA) is an important precedent to improvements in self-management and ultimately health outcomes; however, few interventions targeting BA have been developed for the SCD population. The goal of the present study was to evaluate a technology-enhanced self-management intervention for adolescents and young adults (AYA) with SCD targeting BA domains (ie, disease knowledge, self-efficacy, motivation, and self-management skills). DESIGN/METHODS: Participants were randomized to one of two study arms. SCThrive participants (N = 26) completed six weekly group sessions, an in-person booster session, and used a companion app (iManage) to record symptoms, progress on goals, and connect with other group members. Each SCHealthEd participant (N = 27) received six weekly phone calls on SCD-related and general health education topics. All AYA completed questionnaires assessing BA at baseline and posttreatment. RESULTS: Separate mixed ANOVA analyses to assess for the effects of group (SCThrive/SCHealthEd), time (baseline/posttreatment), and group × time interaction indicated that there was a clinically meaningful improvement (8-point change) in self-efficacy, with a medium effect size, P = .09, η2  = .06, and there was statistically significant improvement in one self-management skill (tracking health), P = .001, d = .71, among SCThrive participants. CONCLUSIONS: The results support the potential for a self-management intervention to improve self-efficacy in AYA with SCD. Health care providers are encouraged to target BA skills to support self-management of AYA with SCD.

The impact of pediatric hematopoietic stem cell transplant timing and psychosocial factors on family and caregiver adjustment.

BACKGROUND: The impact of pediatric hematopoietic stem cell transplant (HCT) on family functioning varies, but little is known about how the timing of HCT in children's treatment course contributes to this variability. This study examines how preexisting child, sibling, and family problems, the length of time between diagnosis to HCT, and children's age at HCT are associated with family and caregiver functioning. PROCEDURE: Caregivers (n = 140) of children (≤18 years old) scheduled to undergo their first HCT completed the Psychological Assessment Tool-HCT and the Impact on Family Scale. Treatment information was extracted from electronic medical records. A bootstrapped multivariate path analysis was used to test the hypotheses. RESULTS: More preexisting family problems related to greater caregiver perceived negative impact of their child's HCT across family and caregiver functioning domains. Less time between diagnosis and HCT was associated with greater caregiver personal strain, particularly for those with younger children undergoing HCT. Younger child age at HCT was also associated with a larger negative impact on family social functioning. CONCLUSIONS: Families with preexisting problems are the most at-risk for experiencing negative impacts related to their child's HCT. The timing of a child's HCT within their treatment course and the child's age during HCT may impact families' social functioning and caregiver adjustment. Screening families for preexisting family problems, particularly for families with young children or who are abruptly learning of their child's need for an HCT, may assist providers in identifying families who would benefit from earlier or more intensive psychosocial support.

Digital Therapeutic Self-Management Intervention in Adolescents With Migraine: Feasibility and Preliminary Efficacy of "Migraine Manager".

OBJECTIVE: The objective of this study was to design, code, and pilot test the feasibility and preliminary efficacy of a self-management digital therapeutic tool for adolescents with migraine. BACKGROUND: Self-management of migraine in adolescents is complex and has important implications for health outcomes. A comprehensive and accessible approach to self-management is needed for youth with migraine, their parents, and clinicians. METHODS: An iterative co-design process was used to develop and optimize the Migraine Manager's digital therapeutic self-management tool. Subsequently, 40 adolescents, age 11-18 years, were enrolled in an 8-week single-arm open label trial (N = 36 analyzed). The primary outcome was headache days. RESULTS: Usage data for Migraine Manager were similar to other health app usage data and feedback from participants was uniformly positive, indicating acceptable feasibility. Preliminary efficacy was demonstrated by a reduction in headache days from 17.2 ± 8.5 at baseline to 7.9 ± 7.2 at 8 weeks (95% CI, -13.0 to -7.8; P < .001). There was also statistically significant improvement in patient physical functioning quality of life reported by both patients (baseline = 55.7 ± 20.4; 8 weeks = 69.7 ± 21.9, P = .005) and parents (baseline = 58.5 ± 22.8; 8 weeks = 74.3 ± 18.1, P = .002), and in parent-reported ingestion issues subscale of the adherence barriers scale from baseline to 8 weeks (baseline = 6.0 ± 2.6; 8 weeks = 5.2 ± 3.0, P = .020). CONCLUSIONS: A self-management digital therapeutic tool for adolescents with migraine can offer care to patients who might not otherwise receive such services. Migraine Manager demonstrated the feasibility and preliminary efficacy in this pilot trial, highlighting the potential beneficial impact of this tool. Larger controlled trials with long-term follow-up are needed to definitively determine the clinical efficacy of Migraine Manager.

Alterations in Brain Function After Cognitive Behavioral Therapy for Migraine in Children and Adolescents.

OBJECTIVES: This basic mechanistic study examined the changes in brain activation and resting-state connectivity after 8 weeks of CBT in youth with migraine. BACKGROUND: Cognitive behavioral therapy (CBT) is a psychological intervention that is effective in reducing pain in migraine patients. However, the neural mechanisms underlying CBT in adolescents with migraine are not yet known. METHODS: Eighteen adolescents with migraine (15 females, age 15.1 ± 2.1 years [mean ± SD]) completed 8 weekly CBT sessions. Before the first and after the final CBT session, participants underwent structural and resting-state blood-oxygen-level-dependent contrast MRI scans. Arterial spin labeling was also used to examine brain activation during the resting state. For connectivity analyses, the right and left amygdala were chosen as seed regions. Relationships of the time courses within these seeds with voxels across the whole brain were evaluated. RESULTS: Headache frequency decreased from 15 ± 7.4 headaches per month before CBT to 10 ± 7.4 after CBT (P < .001). After CBT, greater brain activations in frontal regions involved in cognitive regulation of pain were found. In addition, after CBT increased connectivity between the amygdala and frontal regions was observed. Associations between brain activation and amygdalar connectivity with a reduction in headache frequency were also observed. CONCLUSIONS: Alterations in brain function and amygdalar connectivity with areas involved in nociceptive processing, cognitive function, and emotional regulation may underlie the ability of CBT to aid in the prevention of headaches in migraine patients.

Disease Self-Efficacy and Health-Related Quality of Life in Adolescents With Sickle Cell Disease.

Adolescents and young adults (AYA) with sickle cell disease (SCD) are at risk for poor health-related quality of life (HRQOL). Research suggests that vulnerability factors (eg, disease severity) and self-management resources (eg, disease self-efficacy) jointly impact health outcomes, including HRQOL; however, this has not been studied among AYA with SCD. This study examined the relationship between disease self-efficacy, HRQOL, and disease severity in AYA with SCD. HRQOL was positively correlated with disease self-efficacy and negatively correlated with disease severity. Disease self-efficacy and severity accounted for 35% of variance in HRQOL. Findings support the impact of disease self-efficacy on HRQOL.

Null effects of boot camps and short-format training for PhD students in life sciences.

Many PhD programs incorporate boot camps and summer bridge programs to accelerate the development of doctoral students' research skills and acculturation into their respective disciplines. These brief, high-intensity experiences span no more than several weeks and are typically designed to expose graduate students to data analysis techniques, to develop scientific writing skills, and to better embed incoming students into the scholarly community. However, there is no previous study that directly measures the outcomes of PhD students who participate in such programs and compares them to the outcomes of students who did not participate. Likewise, no previous study has used a longitudinal design to assess these outcomes over time. Here we show that participation in such programs is not associated with detectable benefits related to skill development, socialization into the academic community, or scholarly productivity for students in our sample. Analyzing data from 294 PhD students in the life sciences from 53 US institutions, we found no statistically significant differences in outcomes between participants and nonparticipants across 115 variables. These results stand in contrast to prior studies presenting boot camps as effective interventions based on participant satisfaction and perceived value. Many universities and government agencies (e.g., National Institutes of Health and National Science Foundation) invest substantial resources in boot camp and summer bridge activities in the hopes of better supporting scientific workforce development. Our findings do not reveal any measurable benefits to students, indicating that an allocation of limited resources to alternative strategies with stronger empirical foundations warrants consideration.
