Foundational Curriculum and Core Guidelines for Training in Latinx/a/o-Hispanic Cultural Neuropsychology Across the Lifespan.

OBJECTIVE: The training competency of individual and cultural diversity is an advanced, fundamental competency to health service psychology since 2015. However, there is minimal instruction on how to integrate it into training curricula in neuropsychology, especially at the postdoctoral fellowship level. Our objective was to operationalize the individual and cultural diversity standard to provide a tangible application for educational programs on how to develop a competency-based training model for Latinx/a/o-Hispanic (L/H) cultural neuropsychology across the lifespan. METHOD: The knowledge-based and applied-based competencies necessary to train to be a cultural neuropsychologist delivering services to L/H patients and families are defined. For learners to complete these competencies, training programs need to implement clinical, didactic, research, and professional development core guidelines grounded in cultural neuropsychology. We provide a framework on how to transform each core guideline, including a Didactics Core with foundational readings across a range of L/H topics, and a Report Template to guide the documentation of sociocultural information, language usage, normative data, and other relevant factors in a neuropsychological report. CONCLUSIONS: These cultural neuropsychology competencies and core guidelines need to become a basic core requirement for all neuropsychologists in training. With focused education in culturally based competencies, training programs can cultivate a sense of responsibility, inclusion, justice, and equity to train a generation of neuropsychologists, who intentionally and consistently practice socially responsible neuropsychology.

Preliminary longitudinal evidence for stability of maternal behavior and infant stress regulation among infants born preterm at 4 and 9 months during the Still Face paradigm.

Stress regulation begins to develop in the first year of life through interactions with caregivers, particularly in the presence of stressors. High quality caregiving, characterized by maternal sensitivity and responsiveness to the infant's emotional cues, is particularly important in the development of infant stress regulation. The purpose of this study was to assess the longitudinal stability of, and associations between, maternal interactive behavior and infant stress regulation (indexed by positive infant affect and cortisol reactivity) in response to the Still Face paradigm (SF) in a cohort of infants born preterm (< 32 weeks gestation, N = 22) at four months and nine months (adjusted age). The percent of time mothers spent using specific interaction styles (contingent maternal interaction (CMI), attention seeking, and watching) during Play/baseline, Reunion#1, and Reunion#2 SF episodes was calculated To assess infant stress regulation, two indices were obtained at both 4 and 9 months during the SF paradigm: the percent of positive affect displayed over each SF episode (0-100%) and a neuroendocrine stress response score based on salivary cortisol reactivity. We found three non-significant but medium-large effect size differences between 4 and 9 month variables, with more positive findings at 9 months. Regarding stability within the 4 month and 9 month episodes, maternal behavior and positive infant affect were non-significantly but moderately stable, with maternal watching behavior being particularly stable. Positive infant affect stability between Reunion#1 and Reunion#2 at 4 months was significantly greater than positive infant affect stability across these two episodes at 9 months. Regarding stability across 4 and 9 month (same) episodes, CMI and positive infant affect showed modest but non-significant stability across (same) 4 and 9 month episodes. Finally, with positive infant affect at Reunion#2 as the "outcome" of the Still Face, CMI at both 4 month Play and Reunion#1 episodes were significantly correlated with this "outcome." Further, positive infant affect at Reunion#2 was more strongly correlated with CMI at both Play and Reunion#1 for 4 month old compared with 9 month old infants. Thus, sensitive care appears particularly important for younger infants born preterm, and mothers' behavior early in a repeated stress exposure paradigm may be particularly important in maintaining positive infant affect and in the development of infants' stress regulation more generally. Identifying the longer-term effects of early stress on infant stress regulation, and its relationship with maternal interaction, has important implications for understanding trajectories of regulatory patterns and deficits. A greater understanding of these relationships is particularly important given that greater emotion and neuroendocrine stress regulation in infancy have been directly associated with numerous positive outcomes throughout childhood.

The role of maternal interactive behavior and gestational age in predicting infant affect during the Still-Face Paradigm.

BACKGROUND: Emotion regulation develops through bidirectional affective communication. AIM: To investigate the role of maternal interactive behavior in predicting infant affect among preterm versus full-term infants. STUDY DESIGN: The association between maternal interactive behavior (contingent, attention seeking, watching) and infant affect during a modified Still Face (SF) paradigm in a sample of 22 preterm and 28 full term infants (3 ½ - 4 ½ months old) was investigated. METHODS: Maternal behavior and infant affect were coded in one second intervals. RESULTS: Maternal contingent interaction was positively correlated with positive infant affect (p < 0.001 for Play; p < 0.001 for Reunion#1; p < 0.01 for Reunion#2, respectively), with a stronger association during the second reunion for preterm infants (p < 0.001). In the preterm sample but not in the full-term sample, attention seeking maternal interaction at Play (baseline), Reunion#1, and Reunion#2 were all positively correlated with negative infant affect at Still Face#2. Maternal watching was negatively associated with positive infant affect for the full sample for both Reunion episodes (p < 0.05). Full term infants' negative affect increased from baseline to the first SF episode and then plateaued, whereas preterm infants demonstrated greater negative affect and less recovery throughout. Mothers of full-term infants showed increased contingent responding after the first SF stressor, while mothers of preterm infants did not (p < 0.05). CONCLUSIONS: Preterm infants may be more susceptible to both positive and negative maternal behaviors and mothers of full-term infants may be more responsive to infants' increased distress. Relationship-focused interventions addressing maternal behaviors may enhance positive emotionality and improve self-regulation in medically at-risk infants.

The association of infant temperament and maternal sensitivity in preterm and full-term infants.

Infants who experience sensitive caregiving are at lower risk for numerous adverse outcomes. This is especially true for infants born preterm, leading them to be more susceptible to risks associated with poorer quality caregiving. Some research suggests that preterm and full-term infants differ on temperament, which may contribute to these findings. This study aimed to investigate associations between infant temperament (negative emotionality, positive affectivity/surgency, and orienting/regulatory capacity) and maternal sensitivity among infants born preterm (M = 30.2 weeks) and full term. It was hypothesized that mothers of infants born preterm and mothers of infants with more difficult temperaments would display lower sensitivity, indicated by lower responsiveness to nondistress, lower positive regard, and higher intrusiveness. Videotaped play interactions and a measure of temperament (Infant Behavior Questionnaire) were coded for 18 preterm and 44 full-term infants at 9 months (corrected) age. Results suggest that mothers of preterm and full-term infants differed significantly in responding to their infants, but these results cannot be explained by infant temperament. Preterm status and sociodemographic risk emerged as correlates of maternal behavior, such that mothers of infants born preterm and mothers with greater sociodemographic risk displayed lower levels of maternal sensitivity.

Los infantes que experimentan un cuidado sensible se encuentran bajo un riesgo más bajo en cuanto a numerosos resultados adversos. Esto es especialmente cierto para infantes nacidos prematuramente, lo cual conlleva que ellos sean más susceptibles a los riesgos asociados con una más pobre calidad de cuidado. Alguna investigación sugiere que los infantes prematuros y aquellos de completa gestación difieren en el temperamento, lo cual pudiera contribuir a estos resultados. Este estudio se propuso investigar las asociaciones entre el temperamento del infante (sentido negativo de la emoción, afectividad/resurgencia positiva y capacidad de orientación/regulatoria) y la sensibilidad materna entre infantes nacidos prematuramente (M = 30.2 semanas) y los nacidos dentro de la gestación completa. La hipótesis fue que las madres de infantes nacidos prematuramente y las madres de infantes con temperamentos más difíciles mostrarían una más baja sensibilidad, indicado por una más baja reacción sensible a la falta de angustia, más baja consideración positiva y más alta intrusión. Se codificaron las interacciones de juego grabadas en video y una medida de temperamento (Cuestionario de Conducta del Infante) para 18 prematuros y 44 infantes de gestación completa a los nueves meses (corregidos) de edad. Los resultados sugieren que las madres de infantes prematuros y de gestación completa difirieron significativamente al responder a sus infantes, pero estos resultados no pueden ser explicados con base en el temperamento del infante. La condición de prematuro y el riesgo sociodemográfico surgieron como una correlación del comportamiento materno, al punto que las madres de infantes nacidos prematuramente y las madres con mayores riesgos sociodemográficos mostraron niveles más bajos de sensibilidad materna.

Les nourrissons qui font l'expérience de soins sensibles sont à moindre risque pour bien des résultats adverses. Cela est particulièrement vrai des nourrissons nés prématurés, ce qui les amène à être plus susceptibles aux risques liés à une plus mauvaise qualité de soins de la personne qui prend soin d'eux. Certaines recherches suggèrent que les nourrissons prématurés et les nourrissons à terme diffèrent quant au tempérament, ce qui peut contribuer à ces résultats. Cette étude s'est donné pour but de rechercher les liens entre le tempérament du nourrisson (émotionalité négative, affectivité/dynamisme positif, et capacité d'orientation/régulatoire) et la sensibilité maternelle chez les nourrissons nés prématurés (M = 30,2 semaines) et ceux à plein terme. Nous avons pris pour hypothèse que les mères des nourrissons nés prématurés et les mères de nourrissons ayant des tempéraments plus difficiles feraient preuve d'une sensibilité plus basse, indiquée par une réaction moindre à la non-détresse, un égard positif plus bas et une intrusion plus élevée. Des interactions de jeu filmées et une mesure de tempérament (Questionnaire du Comportement du Nourrisson) ont été codées pour 18 prématurés et 44 nourrissons à termes à neuf mois (âge corrigé). Les résultats suggèrent que les mères de prématurés et de nourrissons à terme ont différé de manière importante dans leur réaction à leurs nourrissons, mais ces résultats ne peuvent pas être expliqués par le tempérament du nourrisson. Le statut de prématuré et le risque sociodémographique ont émergé comme corrélat du comportement maternel, de telle manière que les nourrissons nés prématurés et les mères avec un risque sociodémographique plus élevé ont fait état de niveaux plus bas de sensibilité maternelle.

Self-regulation and emotional reactivity in infants with prenatal exposure to opioids and alcohol.

BACKGROUND: Infants with prenatal substance exposure are at increased risk for developmental problems, with self-regulatory challenges being some of the most pronounced. The current study aimed to investigate the extent to which prenatal substance exposure (alcohol, opioids) impacts infant self-regulation during a relational stressor and the association between self-regulation and infant affect. METHODS: Participants were 100 mother-child dyads recruited prenatally (Mean = 23.8 gestational weeks) and completed the Still Face Paradigm (SFP) when infants were 5 to 8 months of age (Mean = 6.9 months) as part of an ENRICH prospective birth cohort study. Based on prospective repeated assessment of maternal substance use in pregnancy, infants were grouped into: 1) Unexposed controls; 2) Alcohol-exposed; 3) Opioid-exposed due to maternal use of medications for opioid use disorder (MOUD) with or without other opioids; 4) MOUD and alcohol. Infant stress reactivity (negative affect) and self-regulation were assessed during the validated 5-episode SFP. Mixed effects linear models were used to analyze differences in the percent of self-regulation and percent of negative affect among the study groups across SFP episodes, as well as the group-by-self-regulation interaction with respect to infant negative affect. RESULTS: The MOUD+Alcohol group demonstrated significantly lower self-regulation at baseline compared to controls (p < 0.05). There was a significant group-by-self-regulation interaction (p = 0.028). Higher self-regulation was associated with lower negative affect across SFP episodes in the MOUD+Alcohol group (p = 0.025) but not other groups. CONCLUSION: Self-regulation skills are particularly important for emotional modulation in infants with prenatal polysubstance exposure, highlighting the development of these skills as a promising intervention target.

The association between maternal interaction and infant cortisol stress reactivity among preterm and full term infants at 4 months adjusted age.

The purpose of this study was to assess the association between maternal interactive behavior and infant cortisol stress reactivity in response to the Still Face paradigm (SF) in a cohort of four-month old infants (adjusted age) born preterm (<32 weeks gestation, N = 22) compared with infants born full term (>37 weeks gestation, N = 28). Infant cortisol reactivity was calculated as area under the curve (AUC) from baseline to the third cortisol sample (30 min post-SF) using the trapezoidal rule, while the percent of time mothers spent using a contingent interaction style was measured (0-100%) during episodes 1 (Play; baseline), 3 (Reunion#1), and 5 (Reunion#2) while mother-infant dyads participated in the SF paradigm. We hypothesized that because infants born preterm are at increased risk for dysregulation, they would show, compared to full-term infants, a blunted stress response, involving under-responsiveness. We found blunted cortisol stress reactivity among the preterm infants. We also found that mothers of preterm infants demonstrated less contingent maternal interaction during Renion#1 of the SF; and that contingent maternal interaction at Reunion#2 of the SF was protective against cortisol stress reactivity in response to the SF. However, we did not find that the influence of maternal interaction on cortisol reactivity was moderated by gestational age group (full term vs preterm): the association between contingent maternal interaction and stress reactivity was similar for both gestational groups across episodes. In order to improve self-regulation and longer term social and cognitive developmental outcomes in medically at-risk infants, future research is warranted to determine how these findings relate to infants' stress reactions in naturalistic settings, and the directionality and temporal relationship between cortisol stress responses and maternal interactive behavior.

Association Between Executive Functioning and Functional Impairment Among Pediatric Cancer Survivors and Controls.

OBJECTIVE: To examine the impact of cancer treatment upon neurocognitive and functional impairment; and to explore the relationship between these constructs in pediatric cancer survivors compared to controls. METHOD: A cross-sectional cohort of survivors (n = 26) and controls (n = 53) was included. Survivors were off treatment an average of 6.35 years (SD = 5.38; range 1-15 years) and demonstrated an average "medium" Central Nervous System (CNS) treatment intensity score. Participants completed measures of neurocognitive functions including intellectual assessment (RIST) and executive functions (NIH Examiner), while parents reported on children's functional impairment (BIS). RESULTS: Survivors were similar to controls in neurocognitive ability, including intellectual and executive functions, and functional impairment. Regardless of group membership, NIH Examiner performance and functional impairment increased with age. Increased impairment was associated with different neurocognitive variables for survivors versus controls. CONCLUSIONS: Research regarding functional impairment of cancer survivors and the association between neurocognitive deficits and functional impairment has been limited. Our results demonstrate that, while low treatment intensity may confer relative sparing of neurocognitive and executive functioning among survivors, functional impairment continues to be a potential risk. In conclusion, pediatric cancer survivors should be screened for functional difficulties, particularly in the areas of interpersonal relations and self-care.

Two Case Reports of Neuropsychological Outcomes following Pediatric anti-N-methyl D-aspartate Receptor Autoimmune Encephalitis.

Anti-NMDAR autoimmune encephalitis is a rare neurological condition. Limited existing pediatric case studies have shown mild, but persisting, neuropsychological impairments. This report described neuropsychological functioning in two patients treated for anti-NMDAR autoimmune encephalitis. Patient A is a 16-year-old male (10 months after symptom onset) and Patient B is a 5-year-old female (45 months after symptom onset). Contrary to expectations, their cognitive profiles were largely intact, raising the possibility of minimal cognitive implications for some pediatric patients with this condition. Additional research is needed to identify factors that contribute to better cognitive outcomes in children with anti-NMDAR autoimmune encephalitis.

Impact of Erythropoiesis-Stimulating Agents on Behavioral Measures in Children Born Preterm.

OBJECTIVE: To evaluate the impact of erythropoiesis-stimulating agents (ESAs) administered during initial hospitalization and family demographic factors on behavior at 3.5-4 years of age. STUDY DESIGN: Children were enrolled who had previously participated in a randomized study of ESAs (n = 35) or placebo (n = 14) in infants born preterm with birth weights of 500-1250 g. A term healthy control group (n = 22) also was recruited. Behavior was evaluated by parent report with the Behavioral Assessment System of Children-2. Principal component analyses identified 2 demographic factors, a Socioeconomic Composite (SEC) and a Family Stress Composite. A multivariate general linear model evaluated the impact of study group and sex on the 4 composite scales of the Behavioral Assessment System of Children-2. Demographic factors were treated as covariates and interactions with study group (ESA, placebo, and term) were examined. RESULTS: The ESA group had significantly better scores than the placebo group on behavioral symptoms (P = .04) and externalizing scales (P = .04). An interaction was observed between study group and SEC (P = .001). A beneficial effect of ESAs was maximal in the children with lower SEC scores. CONCLUSIONS: The beneficial effects of ESAs on childhood behavior were maximal in children with lower SEC scores. ESAs seemed to ameliorate the adverse impact of lower SEC on behavioral domains seen in the placebo group. This effect was independent of the beneficial effect of ESAs on global cognition we reported previously. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01207778 and NCT00334737.

Maternal touch and infant affect in the Still Face Paradigm: A cross-cultural examination.

Touch between mother and infant plays an important role in development starting from birth. Cross-cultural differences surrounding rearing practices have an influence on parent-infant interaction, including types of touch used and the development of emotional regulation. This study was designed to investigate maternal touch and infant emotional regulation in infant-mother dyads from Ecuador (n=25) and Hispanic dyads from the United States (US) (n=26). Mothers and their 4-month-old full-term infants participated in the Still Face Paradigm. Second-by-second coding of maternal touch and infant affect was completed. Overall the analyses showed that Ecuadorian mothers used more nurturing and accompaniment touch and less attention seeking touch than US Hispanic mothers during the pre-stressor (baseline) episode. Lagged multilevel models were used to investigate the effect of the different types of touch on infant emotional regulation in the groups for the episodes. The data suggest that playful touch had a significant increase in infant affect, whereas accompaniment and attention-seeking touch had a significant decrease in infant affect. Overall, this study provides support for the role of touch in mother-infant synchronicity in relation to infant's emotional regulation. Identifying touch that is more calming is important to foster emotional regulation in infancy, which can have important implications for development.
