A Quality Improvement Network for Interdisciplinary Training in Developmental Disabilities.

Children with developmental disabilities (DD), such as autism spectrum disorder (ASD), have complex health and developmental needs that require multiple service systems and interactions with various professionals across disciplines. The growing number of children and youth identified with ASD or DD, including anxiety and depression, has increased demand for services and need for highly qualified pediatric providers. Federally funded Leadership Education in Neurodevelopmental and related Disabilities (LEND) programs across the United States address today's health care shortages by providing comprehensive, interdisciplinary training to providers from multiple pediatric disciplines who screen, diagnose, and treat those with ASD and DD. Each LEND program develops training methods independently, including quality improvement efforts. In 2014, LEND programs began designing and validating common measures to evaluate LEND training. The LEND Program Quality Improvement (LPQI) Network was established in 2016. Participating LEND programs in the LPQI Network administer validated trainee self-report and faculty-observation measures that address skills in key competency domains of Interdisciplinary or Interprofessional Team Building, Family-Professional Partnerships, and Policy. This study reports data from faculty and trainees from 22 LEND programs that participated in the LPQI Network across the 5-year data collection period. The main outcome of this study was the change in trainee knowledge, skills, and attitudes scores in key competency domains across programs. Overall, trainees made significant knowledge, skills, and attitude gains based on both self-report and faculty observation scores for all 3 competency domains. Data demonstrate the value of LEND programs and feasibility of a national quality improvement approach to evaluate interdisciplinary training and systems-level improvement.

Psychology and Developmental-Behavioral Pediatrics: Interprofessional Collaboration in Clinical Practice.

Providing high-quality clinical services to patients with neurodevelopmental disabilities (NDDs) requires interprofessional collaboration. This article highlights the importance of collaboration between psychology and developmental-behavioral pediatrics (DBP) to promote diagnosis, treatment recommendations, and integrated care for patients and their families. Interprofessional collaboration requires health care providers to work together toward solutions, including diagnosis, treatment recommendations, and ongoing care coordination. Case examples are presented to capture collaborative practice between psychology and DBP. Several established programs for providing interprofessional collaboration are highlighted, with noted benefits and barriers to collaborative care for NDD patients.

Evidence-Informed Milestones for Developmental Surveillance Tools.

The Centers for Disease Control and Prevention's (CDC) Learn the Signs. Act Early. program, funded the American Academy of Pediatrics (AAP) to convene an expert working group to revise its developmental surveillance checklists. The goals of the group were to identify evidence-informed milestones to include in CDC checklists, clarify when most children can be expected to reach a milestone (to discourage a wait-and-see approach), and support clinical judgment regarding screening between recommended ages. Subject matter experts identified by the AAP established 11 criteria for CDC milestone checklists, including using milestones most children (≥75%) would be expected to achieve by specific health supervision visit ages and those that are easily observed in natural settings. A database of normative data for individual milestones, common screening and evaluation tools, and published clinical opinion was created to inform revisions. Application of the criteria established by the AAP working group and adding milestones for the 15- and 30-month health supervision visits resulted in a 26.4% reduction and 40.9% replacement of previous CDC milestones. One third of the retained milestones were transferred to different ages; 67.7% of those transferred were moved to older ages. Approximately 80% of the final milestones had normative data from ≥1 sources. Social-emotional and cognitive milestones had the least normative data. These criteria and revised checklists can be used to support developmental surveillance, clinical judgment regarding additional developmental screening, and research in developmental surveillance processes. Gaps in developmental data were identified particularly for social-emotional and cognitive milestones.

Interobserver and Intraobserver Reliability of Hepatic Shear Wave Elastography and the Influence of Fasted Versus Nonfasted States in Healthy Volunteers.

OBJECTIVES: The primary objective of this study was to assess the effect of fasting versus ingestion of food and water on hepatic measurements by shear wave elastography (SWE) in healthy participants. The secondary objective was to assess inter- and intra-reader reliability of hepatic elastography in healthy participants. METHODS: Twenty healthy participants were enrolled in this prospective study and underwent quantitative SWE under fasting conditions and after the ingestion of water and food and water. Two blinded sonographers each independently performed a total of 6 sessions of hepatic SWE in each participant. Sessions 1 to 3 were performed on day 0 and sessions 4 to 6 on day 7. Statistical tests used included the Wilcoxon signed ranks test, the intraclass correlation coefficient, and Bland-Altman plots. RESULTS: There were no significant differences in hepatic SWE measurements after the ingestion of water versus the fasting state. Statistical significance was assessed as P < 0.05. The postprandial status had a statistically significant effect on hepatic SWE measurements at 1 hour (P = .04) but not at 3 hours (P = .08). By the intraclass correlation coefficient, there was poor-to-moderate inter-reader agreement and minimal-to-moderate intra-reader agreement. The median inter-reader difference in SWE measurements ranged from 0.66 to 0.96 kPa. The median intra-reader difference ranged from 0.43 to 0.55 kPa. CONCLUSIONS: Our study shows that the ingestion of water has no effect on hepatic SWE measurements in healthy participants. The postprandial state had a significant effect on SWE measurements at 1 hour after ingestion but not at 3 hours. The inter-reader and intra-reader agreements were variable and moderate at best.

Increasing Early Childhood Screening in Primary Care Through a Quality Improvement Collaborative.

OBJECTIVES: Multiple early childhood screenings are recommended, but gaps persist in implementation. Our aim for this project was to improve screening, discussion, referral, and follow-up of development, autism spectrum disorder (ASD), maternal depression, and social determinants of health (SDoH) to 90% by July 2018. METHODS: This 1-year national quality improvement collaborative involved 19 pediatric primary care practices. Supported by virtual and in-person learning opportunities, practice teams implemented changes to early childhood screening. Monthly chart reviews were used to assess screening, discussion, referral, and follow-up for development, ASD, maternal depression, and SDoH. Parent surveys were used to assess parent-reported screening and referral and/or resource provision. Practice self-ratings and team surveys were used to assess practice-level changes. RESULTS: Participating practices included independent, academic, hospital-affiliated, and multispecialty group practices and community health centers in 12 states. The collaborative met development and ASD screening goals of >90%. Largest increases in screening occurred for maternal depression (27% to 87%; +222%; P < .001) and SDoH (26% to 76%; +231%; P < .001). Statistically significant increases in discussion of results occurred for all screening areas. For referral, significant increases were seen for development (53% to 86%; P < .001) and maternal depression (23% to 100%; P = .008). Parents also reported increased screening and referral and/or resource provision. Practice-level changes included improved systems to support screening. CONCLUSIONS: Practices successfully implemented multiple screenings and demonstrated improvement in subsequent discussion, referral, and follow-up steps. Continued advocacy for adequate resources to support referral and follow-up is needed to translate increased screening into improved health outcomes.

Association of prenatal opiate exposure with youth outcomes assessed from infancy through adolescence.

OBJECTIVE: This study examined acute findings and long-term outcome trajectories between birth and adolescence in children with prenatal opiate exposure. STUDY DESIGN: Ninety children (45 opiate-exposed, 45 non-exposed) completed assessments between 1 month and 15 years of age. Outcome variables (medical, anthropomorphic, developmental, and behavioral) were analyzed at individual time points and using longitudinal statistical modeling. RESULTS: Opiate-exposed infants displayed transient neurologic findings, but no substantial signs or symptoms long term. There were no group differences in growth, cognitive functioning, or behavior at individual time periods; however, the trajectories of outcomes using longitudinal analyses adjusting for variables known to impact outcome demonstrated increased deficits among opiate-exposed children over time with regards to weight, head circumference, cognitive functioning, and behavior. CONCLUSIONS: Findings support concerns that maternal opiate use during pregnancy may negatively impact a child's developmental trajectory, which in turn may impose concerns to society (e.g., increased need for social, medical, and/or educational services).

Improving Developmental Screening, Discussion, and Referral in Pediatric Practice.

Objective. Although pediatricians' use of standardized screening tools for identifying developmental delays has increased, only 63% of pediatricians report performing standardized screening as recommended. The purpose of the current quality improvement project was to improve developmental monitoring, screening, and referral for developmental concerns by pediatricians. Method. Twenty-eight pediatricians completed an in-person meeting, monthly webinars, and individualized feedback from an Expert Work Group on progress across a 3-month action period. Results. Statistically significant increases were observed in rates of autism screening, discussions of screening results with families, and referral following abnormal results. There was no statistically significant change in rates of general developmental screening. Comparing self-report with record review, pediatricians overestimated the extent to which they conducted discussion and referral. Conclusions. Universal screening for all children has yet to be achieved. The current project supports that practice-based improvements can be made and delineates some of the routes to success.

Socio-demographic, maternal, and child indicators of socioemotional problems in 2-year-old children: A cohort study.

Throughout infancy and early childhood, stable and secure relationships with caregivers are needed to promote optimal socioemotional (SE) and cognitive development.The objective is to examine socio-demographic, maternal, and child indicators of SE problems in 2-year-olds living in an urban-suburban community in the southern United States.Mother-infant pairs enrolled in a prospective pregnancy cohort study.Shelby County (Memphis), Tennessee.One thousand five hundred three women were recruited during their second trimester and followed with their children through the child's age of 2 years.Child SE development was measured by the Brief Infant-Toddler Social Emotional Assessment at 2 years of age. Mothers reported their own behavioral and mental health, temperament, parenting stress, and potential for child abuse during gestation and/or when their child was 1 year of age. Examiners measured maternal IQ during data collection at the child's age of 1 year. Child communication, cognitive development, and risk for autism spectrum disorder were assessed at 1 and 2 years of age. Multivariable regression models were developed to predict mother-reported SE problems.In bivariate analyses, multiple maternal behavioral and mental health indicators and child cognitive skills were associated with reported child SE problems at 2 years of age. Regression analyses, controlling for socio-demographic, maternal, and child variables, showed the following factors were independently associated with mother-reported child SE problems: maternal education of high school or less, lower maternal IQ, higher maternal cyclothymic temperament score, greater parenting stress, greater maternal psychological distress, lower child expressive communication score, and child risk for autism spectrum disorder. Socio-demographic variables accounted for the variance often attributed to race.Since mothers in the study were medically low-risk, generalizing these findings to medically high-risk mothers is unwarranted. In addition, these SE outcomes in 2-year-old children do not reflect the trajectory of SE development throughout early childhood.Attention to independent indicators of future SE problems in children may help identify individual children and families needing intervention and target public prevention/treatment programs in communities.

Maternal and Child Characteristics Associated With Mother-Child Interaction in One-Year-Olds.

Mothers' interactions with their young children have predicted later child development, behavior, and health, but evidence has been developed mainly in at-risk clinical samples. An economically and racially diverse sample of pregnant women who were not experiencing a high-risk pregnancy were recruited to participate in a community-based, longitudinal study of factors associated with child cognitive and social-emotional development during the first 3 years. The purpose of the present analysis was to identify associations between the characteristics of 1125 mothers and their 1-year-olds and the mothers' and children's scores on the Nursing Child Assessment Teaching Scale (NCATS). A multivariable approach was used to identify maternal and child characteristics associated with NCATS scores and to develop prediction models for NCATS total and subscale scores of mothers and children. Child expressive and receptive communication and maternal IQ, marital status, age, and insurance predicted NCATS Mother total score, accounting for 28% of the score variance. Child expressive communication and birth weight predicted the NCATS Child total score, accounting for 4% of variance. Child's expressive communication and mother's IQ and marital status predicted NCATS mother-child total scores. While these findings were similar to reports of NCATS scores in at-risk populations, no previous teams examined all of the mother and child characteristics included in this analysis. These findings support the utility of the NCATS for assessing mother-child interaction and predicting child outcomes in community-based, non-clinical populations. © 2017 Wiley Periodicals, Inc.

Maternal and infant affect at 4 months predicts performance and verbal IQ at 4 and 7 years in a diverse population.

Using existing longitudinal data from 570 infants in the Maternal Lifestyle Study, we explored the predictive value of maternal and infant affect and maternal vocalizations during 2 minutes of face-to-face interactions at 4 months on IQ scores at 4.5 and 7 years. After controlling for demographic factors, maternal depression, and prenatal drug exposure, maternal positive affect and maternal positive vocalizations emerged as predictors of both verbal and performance IQ at 4.5 and 7 years. Although infant positive affect during the interaction with the mother was not predictive of these outcome measures, infant positive affect towards an examiner predicted verbal but not performance IQ at 4.5 years. These results suggest that maternal positive affect may index emotional engagement in interaction that facilitates both verbal and nonverbal cognitive development, while infant social positive affect is specifically related to the acquisition of verbal reasoning abilities. These findings are significant because they are based on a discrete snapshot of observable behavior in infancy (just 2 minutes of interaction), because they extend the range of maternal behaviors and characteristics known to support positive developmental outcomes, and because they are derived from high-risk infants where prevention efforts may be beneficial. Potential mechanisms for these associations are discussed, as are the clinical implications for identifying dyads most in need of targeted interventions.

Infants' early visual attention and social engagement as developmental precursors to joint attention.

This study examined infants' early visual attention (at 1 month of age) and social engagement (4 months) as predictors of their later joint attention (12 and 18 months). The sample (n = 325), drawn from the Maternal Lifestyle Study, a longitudinal multicenter project conducted at 4 centers of the National Institute of Child Health and Human Development Neonatal Research Network, included high-risk (cocaine-exposed) and matched noncocaine-exposed infants. Hierarchical regressions revealed that infants' attention orienting at 1 month significantly predicted more frequent initiating joint attention at 12 (but not 18) months of age. Social engagement at 4 months predicted initiating joint attention at 18 months. Results provide the first empirical evidence for the role of visual attention and social engagement behaviors as developmental precursors for later joint attention outcome. (PsycINFO Database Record

Transactional relations between caregiving stress, executive functioning, and problem behavior from early childhood to early adolescence.

Developmental psychopathologists face the difficult task of identifying the environmental conditions that may contribute to early childhood behavior problems. Highly stressed caregivers can exacerbate behavior problems, while children with behavior problems may make parenting more difficult and increase caregiver stress. Unknown is: (a) how these transactions originate, (b) whether they persist over time to contribute to the development of problem behavior and (c) what role resilience factors, such as child executive functioning, may play in mitigating the development of problem behavior. In the present study, transactional relations between caregiving stress, executive functioning, and behavior problems were examined in a sample of 1,388 children with prenatal drug exposures at three developmental time points: early childhood (birth to age 5), middle childhood (ages 6 to 9), and early adolescence (ages 10 to 13). Transactional relations differed between caregiving stress and internalizing versus externalizing behavior. Targeting executive functioning in evidence-based interventions for children with prenatal substance exposure who present with internalizing problems and treating caregiving psychopathology, depression, and parenting stress in early childhood may be particularly important for children presenting with internalizing behavior.

Early caregiving stress exposure moderates the relation between respiratory sinus arrhythmia reactivity at 1 month and biobehavioral outcomes at age 3.

There is a growing scientific interest in the psychophysiological functioning of children living in low-socioeconomic status (SES) contexts, though this research is complicated by knowledge that physiology-behavior relations often operate differently in these environments among adults. Importantly, such research is made more difficult because SES may be a proxy for a wide range of risk factors including poor caregiving and exposure to parental substance use. We used factor analysis to organize risk-exposure data collected from 827 children-many of whom were raised in low-SES contexts and exposed to substances prenatally-into dissociable components including economic stress, caregiving stress (e.g., stress the caregiver may experience, including parental psychopathology), and postnatal substance exposure. These factors, along with respiratory sinus arrhythmia (RSA) reactivity at age 1 month, were used to predict behavior dysregulation and resting RSA at age 3 years. A significant RSA Reactivity × Caregiving Stress interaction indicated that infants who exhibited high RSA reactivity at 1 month experienced the greatest behavior dysregulation at 3 years, but only when they were exposed to high levels of caregiving stress. Among African Americans, the highest resting RSA at 3 years was found in infants with less RSA reactivity, but only if they also experienced less caregiving stress. Our work is consistent with biological sensitivity to context, adaptive calibration, and allostatic load models, and highlights the importance of studying Physiology × Environment interactions in low-SES contexts for predicting behavior and resting RSA.

Cortisol reactivity to social stress as a mediator of early adversity on risk and adaptive outcomes.

Children chronically exposed to stress early in life are at increased risk for maladaptive outcomes, though the physiological mechanisms driving these effects are unknown. Cortisol reactivity was tested as a mediator of the relation between prenatal substance exposure and/or early adversity on adaptive and maladaptive outcomes. Data were drawn from a prospective longitudinal study of prenatal substance exposure (N = 860). Cortisol reactivity was assessed at age 11. Among African Americans, prenatal substance exposure exerted an indirect effect through early adversity and cortisol reactivity to predict externalizing behavior, delinquency, and a positive student-teacher relationship at age 11. Decreased cortisol reactivity was related to maladaptive outcomes, and increased cortisol reactivity predicted better executive functioning and a more positive student-teacher relationship.

Physiological correlates of neurobehavioral disinhibition that relate to drug use and risky sexual behavior in adolescents with prenatal substance exposure.

Physiological correlates of behavioral and emotional problems, substance use onset and initiation of risky sexual behavior have not been studied in adolescents with prenatal drug exposure. We studied the concordance between baseline respiratory sinus arrhythmia (RSA) at age 3 and baseline cortisol levels at age 11. We hypothesized that children who showed concordance between RSA and cortisol would have lower neurobehavioral disinhibition scores which would in turn predict age of substance use onset and first sexual intercourse. The sample included 860 children aged 16 years participating in the Maternal Lifestyle Study, a multisite longitudinal study of children with prenatal exposure to cocaine and other substances. Structural equation modeling was used to test pathways between prenatal substance exposure, early adversity, baseline RSA, baseline cortisol, neurobehavioral disinhibition, drug use, and sexual behavior outcomes. Concordance was studied by examining separate male and female models in which there were statistically significant interactions between baseline RSA and cortisol. Prenatal substance exposure was operationalized as the number of substances to which the child was exposed. An adversity score was computed based on caregiver postnatal substance use, depression and psychological distress, number of caregiver changes, socioeconomic and poverty status, quality of the home environment, and child history of protective service involvement, abuse and neglect. RSA and cortisol were measured during a baseline period prior to the beginning of a task. Neurobehavioral disinhibition, based on composite scores of behavioral dysregulation and executive dysfunction, substance use and sexual behavior were derived from questionnaires and cognitive tests administered to the child. Findings were sex specific. In females, those with discordance between RSA and cortisol (high RSA and low cortisol or low RSA and high cortisol) had the most executive dysfunction which, in turn, predicted earlier initiation of alcohol by age 16. Among boys, there also existed a significant baseline RSA by baseline cortisol interaction. Boys with low baseline RSA and high baseline cortisol had the highest levels of behavioral dysregulation. This increase in behavioral dysregulation was in turn related to initiation of alcohol use by age 16 and lower age of first sexual intercourse. We found sex-specific pathways to the initiation of alcohol use and risky sexual behavior through the combined activity of parasympathetic and neuroendocrine functioning. The study of multiple physiological systems may suggest new pathways to the study of age of onset of substance use and engagement in risky sexual behavior in adolescents.

The contributions of early adverse experiences and trajectories of respiratory sinus arrhythmia on the development of neurobehavioral disinhibition among children with prenatal substance exposure.

Neurobehavioral disinhibition (ND) is a complex condition reflecting a wide range of problems involving difficulties with emotion regulation and behavior control. Respiratory sinus arrhythmia (RSA) is a physiological correlate of emotion regulation that has been studied in a variety of at-risk populations; however, there are no studies of RSA in children with ND. Data were drawn from a prospective longitudinal study of prenatal substance exposure that included 1,073 participants. Baseline RSA and RSA reactivity to an attention-demanding task were assessed at 3, 4, 5, and 6 years. ND was assessed at ages 8/9, 11, and 13/14 years via behavioral dysregulation and executive dysfunction composite measures. Greater exposure to early adversity was related to less RSA reactivity at 3 years, increases in RSA reactivity from ages 3 to 6 years, and increased behavioral dysregulation from ages 8/9 to 13/14. RSA reactivity was examined as a moderator of the association between early adversity and changes in ND. A significant Early Adversity × RSA Reactivity quadratic interaction revealed that children with decelerations in RSA reactivity exhibited increases in behavioral dysregulation, regardless of their exposure to early adversity. However, greater exposure to early adversity was related to greater increases in behavioral dysregulation, but only if children exhibited accelerations in RSA reactivity from ages 3 to 6 years. The results contribute to our understanding of how interactions across multiple levels of analysis contribute to the development of ND.

The role of prenatal substance exposure and early adversity on parasympathetic functioning from 3 to 6 years of age.

We employed latent growth curve analysis to examine trajectories of respiratory sinus arrhythmia (RSA) from 3 to 6 years among children with varying levels of prenatal substance exposure and early adversity. Data were drawn from a prospective longitudinal study of prenatal substance exposure that included 1,121 participants. Baseline RSA and RSA reactivity to an attention-demanding task were assessed at 3, 4, 5, and 6 years. Overall, there were significant individual differences in the trajectories of RSA reactivity, but not baseline RSA, across development. Greater levels of prenatal substance exposure, and less exposure to early adversity, were associated with increased RSA reactivity at 3 years, but by 6 years, both were associated with greater RSA reactivity. Prenatal substance exposure had an indirect influence through early adversity on growth in RSA reactivity. Results are in support of and contribute to the framework of allostatic load.

Risk-taking behavior among adolescents with prenatal drug exposure and extrauterine environmental adversity.

OBJECTIVE: High-risk environments characterized by familial substance use, poverty, inadequate parental monitoring, and violence exposure are associated with an increased propensity for adolescents to engage in risk-taking behaviors (e.g., substance use, sexual behavior, and delinquency). However, additional factors such as drug exposure in utero and deficits in inhibitory control among drug-exposed youth may further influence the likelihood that adolescents in high-risk environments will engage in risk-taking behavior. This study examined the influence of prenatal substance exposure, inhibitory control, and sociodemographic/environmental risk factors on risk-taking behaviors in a large cohort of adolescents with and without prenatal cocaine exposure (PCE). METHOD: Risk-taking behavior (delinquency, substance use, and sexual activity) was assessed in 963 adolescents (433 cocaine-exposed, 530 nonexposed) at 15 years of age. RESULTS: Prenatal cocaine exposure predicted later arrests and early onset of sexual behavior in controlled analyses. Associations were partially mediated, however, by adolescent inhibitory control problems. PCE was not associated with substance use at this age. In addition, male gender, low parental involvement, and violence exposure were associated with greater odds of engaging in risk-taking behavior across the observed domains. CONCLUSIONS: Study findings substantiate concern regarding the association between prenatal substance exposure and related risk factors and the long-term outcomes of exposed youth. Access to the appropriate social, educational, and medical services is essential in preventing and intervening with risk-taking behaviors and the potential consequences (e.g., adverse health outcomes and incarceration), especially among high-risk adolescent youth and their families.

Prenatal substance exposure: neurobiologic organization at 1 month.

OBJECTIVE: To examine the autonomic nervous system and neurobehavioral response to a sustained visual attention challenge in 1-month-old infants with prenatal substance exposure. STUDY DESIGN: We measured heart rate, respiratory sinus arrhythmia, and neurobehavior during sustained visual orientation tasks included in the Neonatal Intensive Care Unit Network Neurobehavioral Scale in 1129 1-month-old infants with prenatal substance exposure. Four groups were compared: infants with prenatal cocaine and opiate exposure, infants with cocaine exposure, infants with opiate exposure, and infants with exposure to other substances (ie, alcohol, marijuana, and tobacco). RESULTS: The infants with prenatal exposure to both cocaine and opiates had the highest heart rates and lowest levels of respiratory sinus arrhythmia during a sustained visual attention challenge compared with the other 3 groups. Infants with prenatal cocaine and opiate exposure had poorer quality of movement and more hypertonicity during the Neonatal Intensive Care Unit Network Neurobehavioral Scale examination. They also had more nonoptimal reflexes and stress/abstinence signs compared with infants with prenatal exposure to cocaine only and those with prenatal exposure to alcohol, tobacco, and marijuana. CONCLUSION: Problems with arousal regulation were identified in infants with prenatal substance exposure. Autonomic dysregulation has been implicated as a mechanism by which these difficulties occur. Our results suggest that infants with prenatal exposure to both cocaine and opiates have the greatest autonomic response to the challenge of a sustained visual attention task, possibly putting these infants at risk for problems associated with physiologic and behavioral regulation, a necessary prerequisite for early learning.
