The effects of the Newborn Behavioral Observations (NBO) system in early intervention: A multisite randomized controlled trial.

The purpose of this pilot study was to evaluate the effect of an infant mental health intervention, the Newborn Behavioral Observations system (NBO), versus usual care (UC) on infant neurodevelopment and maternal depressive symptoms in early intervention (EI). This multisite randomized trial enrolled newborns into the NBO (n = 16) or UC group (n = 22) and followed them for 6 months. Outcome measures included the Battelle Developmental Inventory (BDI-2), Bayley Scales of Infants Development (BSID-III), and Center for Epidemiologic Studies Depression Scale (CES-D). The CES-D and BSID-III were collected at 3- and 6-months post EI entry and the BDI-2 was collected at EI entry and 6-months post-EI entry. We estimated group differences [95% CI], adjusting for program characteristics. At 6 months, the NBO group had greater gains in Communication (b = 1.0 [0.2, 1.8]), Self-Care (b = 2.0 [0.1, 3.9]), Perception and Concepts (b = 2.0 [0.4, 3.6]), and Attention and Memory (b = 3.0 [0.4, 6.0]) than the UC group. The NBO group also had greater decline in maternal postnatal depressive symptoms (b = -2.0 [-3.7, -0.3]) than the UC group. Infants receiving the NBO infant mental health intervention had greater gains in cognitive and adaptive functions at 6 months than infants receiving UC. Caregivers receiving NBO care had greater improvements in maternal depressive symptoms than caregivers receiving UC.

El propósito de este estudio piloto fue evaluar el efecto que una intervención de salud mental infantil, el sistema de Observación de Comportamiento del Recién Nacido (NBO), versus el cuidado usual (UC), tiene en el desarrollo neurológico del infante y los síntomas de depresión materna en la Temprana Intervención (EI). Este ensayo al azar de múltiples lugares inscribió a recién nacidos en el NBO (n = 16) o en el grupo UC (n = 22) y les dio seguimiento por 6 meses. Las medidas de los resultados incluyeron el Inventario Battelle del Desarrollo (BDI-2), las Escalas Bayley del Desarrollo de Infantes (BSID-III), y la Escala de Depresión del Centro para Estudios Epidemiológicos (CES-D). El CES-D y BSID-III fueron implementados a los 3 y 6 meses posteriores a la entrada en EI y el BDI-2 fue implementado al momento de entrar en EI y a los 6 meses posteriores a dicha entrada. Estimamos las diferencias de grupos [95% CI], con ajustes en cuanto a características del programa. A los 6 meses, el grupo NBO presentaba mayores logros en Comunicación (b = 1.0 [0.2, 1.8]), Autocuidado (b = 2.0 [0.1, 3.9]), Percepción y Conceptos (b = 2.0 [0.4, 3.6]) y Atención y Memoria (b = 3.0 [0.4, 6.0]) que el grupo de UC. El grupo NBO también tuvo una mayor baja en síntomas maternos depresivos postnatales (b = 2.0 [-3.7, -0.3]) que el grupo UC. Los infantes que recibían la intervención NBO tuvieron mayores logros en la función cognitiva y adaptiva a los 6 meses que los infantes del grupo UC. Aquellos cuidadores que recibían el cuidado NBO presentaron mejoras significativamente mayores en síntomas depresivos maternos que los cuidadores del grupo UC.

Le but de cette étude pilote était d'évaluer l'effet d'une intervention en santé mentale du nourrisson, le système d'Observation Comportementale du Nourrisson (en anglais, Newborn Behavioral Observation system, soit NBO utilisé ici dans ce texte), par rapport aux soins ordinaires (ici abbrégé SI) sur le neurodéveloppement du nourrisson et les symptômes dépressifs maternels dans l'Intervention Précoce (IP). Cet essai randomisé effectué sur plusieurs sites a concerné des nouveaux-nés dans le NBO (n = 16) ou le groupe SI (n = 22) et les a suivis pendant 6 mois. Les mesures de résultat ont inclus l'Inventaire du Développement de Battelle (BDI-2), les Echelles Bayley de Développement des Nourrissons (BSID-III) et les Echelles de Dépression du Centre d'Etudes Epidémiologiques (CES-D). Les CES-D et BSID-III ont été faites à 3 et à 6 mois après l'entrée en IP et la BDI-2 a été faite à l'entrée en IP et à 6 mois après l'entrée en IP. Nous avons estimé les différences de groupe [95% CI), en faisant des ajustements pour les caractéristiques du programme. A six mois, le groupe NBO avait fait de plus grands gains en Communication (b = 1,0 [0,2, 1,8]), Autosoin (b = 2,0 [0,1, 3,9]), Perception & Concepts (b = 2,0 [0,4, 3,6]), et Attention & Mémoire (b = 3,0 [0,4, 6,0]) que le groupe SI. Le groupe NBO a également vu le plus grand déclin dans les symptômes dépressifs postnatals maternels (b = -2,0 [-3,7, -0,3]) par rapport au groupe SI. Les nourrissons recevant l'intervention NBO ont fait preuve de plus grands gains dans la fonction cognitive et adaptive à 6 mois, par rapport aux nourrissons SI. Les personnes prenant soin des enfants et recevant le soin NBO ont témoigné d'améliorations plus importantes dans les symptômes dépressifs maternels que le groupe SI.

A Pilot Validation Study of the Newborn Behavioral Observations System: Associations with Salivary Cortisol and Temperament.

OBJECTIVE: There are few standardized neonatal neurobehavioral instruments available for longitudinal child development research. We adapted an established clinical tool, the Newborn Behavioral Observations (NBO) system, for research by standardizing the administration protocol and expanding the 3-point coding scale to 5 points. METHODS: We administered the 5-point NBO to 144 racially/ethnically diverse late preterm or term infants born to low-income women (average age 5 weeks). Cronbach's alphas were calculated to determine internal consistency reliability of Autonomic, Motor, Organization of State, and Responsivity subscales. We examined concurrent validity using subscale associations with infant salivary cortisol reactivity to the NBO and maternally reported infant temperament. RESULTS: Two of the 4 NBO subscales, Organization of State and Responsivity, had excellent (0.91) and good (0.76) reliability, respectively, and were retained for further analyses. Infants with higher Organization of State scores (more optimal regulation) demonstrated lower cortisol reactivity (r = -0.30, p < 0.01) and temperamental negativity (r = -0.16, p < 0.05). Responsivity was unrelated to cortisol reactivity or temperament. CONCLUSIONS: State regulation, as measured by the 5-point NBO, was associated with a biologic marker of infant stress response to the NBO administration and reported temperament. Poor reliability of the NBO's 3-item Autonomic and 7-item Motor subscales suggests that further psychometric research in other samples and likely refinement are needed. Given the paucity of neurobehavioral assessment tools for infants, these findings justify such research as next steps in the incremental progression toward the development of a practical, reliable, and predictive measure of early neurobehavioral development.

A neurobehavioral intervention incorporated into a state early intervention program is associated with higher perceived quality of care among parents of high-risk newborns.

The purpose of this study is to compare two models of early intervention (EI) service delivery-a neurobehavioral intervention and usual care-on parents' perceived quality of EI service delivery. Families of newborns referred to EI were randomly assigned to a neurobehavioral intervention or usual care group and followed until the infant was 12 weeks corrected gestational age. The intervention group (n = 25) received a weekly neurobehavioral intervention. The usual care group (n = 13) received standard weekly home visits. Mothers completed the Home Visiting Index (HVI) measuring the quality of EI service delivery. Mixed linear regression was used to examine group differences in quality scores. The intervention group reported higher quality of care related to facilitating optimal parent-infant social interaction (mean difference = 2.17, 95% CI: 0.41, 3.92).A neurobehavioral model of service delivery can be successfully integrated into EI programming and appears to be associated with higher parent-reported perceived quality.

The competent newborn and the neonatal behavioral assessment scale: T. Berry Brazelton's legacy.

This article celebrates Berry Brazelton's extraordinary contribution to our understanding of child development by focusing on two representative themes. The first is that newborns are competent and organized from the very beginning and that the neonate is in a dynamic rather than passive relationship with the environment. The second is the recognition that the newborn period is an extremely sensitive stage in the transition to parenthood and as such may be the intervention "touchpoint" par excellence for professionals who are dedicated to giving children and families the best possible start in life.

Prenatal organochlorine exposure and measures of behavior in infancy using the Neonatal Behavioral Assessment Scale (NBAS).

BACKGROUND: Previous literature suggests an association between organochlorines and behavioral measures in childhood, including inattention. OBJECTIVE: This study was designed to assess whether prenatal organochlorine exposure is associated with measures of attention in early infancy. METHODS: We investigated an association between cord serum polychlorinated biphenyls (PCBs) and p,p'-dichlorodiphenyl dichloroethene (DDE) levels and measures of attention from the Neonatal Behavioral Assessment Scale (NBAS) in a cohort of 788 infants born 1993-1998 to mothers residing near a PCB-contaminated harbor and Superfund site in New Bedford, Massachusetts. RESULTS: Medians (ranges) for the sum of four prevalent PCB congeners and DDE levels were 0.19 (0.01-4.41) and 0.30 (0-10.29) ng/g serum, respectively. For the 542 subjects with an NBAS exam at 2 weeks, we observed consistent inverse associations between cord serum PCB and DDE levels and NBAS measures of alertness, quality of alert responsiveness, cost of attention, and other potential attention-associated measures including self-quieting and motor maturity. For example, the decrement in quality of alert responsiveness score was -0.51 (95% confidence interval, -0.99 to -0.03) for the highest quartile of exposure to the sum of four prevalent PCB congeners compared with the lowest quartile. We found little evidence for an association with infant orientation, habituation, and regulation of state, assessed as summary cluster measures. CONCLUSIONS: Our findings provide evidence for an association between low-level prenatal PCB and DDE exposures and poor attention in early infancy. Further analyses will focus on whether organochlorine-associated decrements in attention and attention-related skills in infancy persist in later childhood.

Neonatal behavioral characteristics and later behavioral problems.

The purposes of this study were (1) to evaluate the usefulness of the Neonatal Behavioral Assessment Scale (NBAS) as a tool to assess the risk of later behavioral problems, (2) to analyze the relationship between neonatal behavioral characteristics and behavioral problems in childhood. Subjects were 77 very-low-birth-weight infants admitted to the NICU at the Nagasaki University Hospital, Nagasaki, Japan. The results suggest that behavioral characteristics such as poor motor performance, poor state regulation, and poor interaction ability in the neonatal period are risk factors for behavioral problems in childhood. The NBAS could help clinicians to identify neonates at risk of later behavioral problems.

Comparison of kangaroo care and standard care: behavioral organization, development, and temperament in healthy, low-birth-weight infants through 1 year.

OBJECTIVE: To determine whether Kangaroo Care (KC) for healthy, low-birth-weight (LBW) infants can promote better behavioral and developmental outcomes. STUDY DESIGN: In this historical control study, 26 infants in the KC group (GA: 34.3+/-2.5 weeks, BW: 1833.9+/-167.6 g) and 27 infants in the comparison group who received the standard medical-nursing care (34.6+/-2.3 weeks, 1850.9+/-156.7 g) were analyzed by the Neonatal Behavioral Assessment Scale (NBAS) at 40 weeks of postmenstrual age, the Bayley Scales of Infant Development and the Carey's Infant Temperament Questionnaire (ITQ) at 6 and 12 months corrected ages. RESULTS: KC infants had significantly higher NBAS scores in Orientation, State Regulation, and Supplementary items; lower Intensity scores and higher Mood scores at 6 months on the ITQ; and higher Bayley Scales score at 12 months. CONCLUSION: KC effectively promoted neonatal behavioral organization and enhanced developmental outcome over the first year of life for LBW infants.

Prenatal marijuana exposure and neonatal outcomes in Jamaica: an ethnographic study

OBJECTIVE. To identify neurobehavioral effects of prenatal marijuana exposure on neonates in rural Jamaica. DESIGN. Ethnographic field studies and standardized neuro-behavior assessments during the neonatal period. SETTING. Rural Jamaica in heavy-marijuana-using population. PARTICIPANTS. Twenty-four Jamaican neonates exposed to marijuana prenatally and 20 nonexposed mnonnates were compare at 3 days and 1 month old, using the Brazelton Neonatal Assessment Scale, including supplementary items to capture possible subtle effects. There were no significant differences between exposed and nonexposed neonates on day 3. At 1 month, the exposed neonates showed better physiological stability and required less examiner facilitation to reach organized states. The neonates of heavy-marijuana-using mothers had better scores on autonomic stability, quality of alertness, irritability, and self-refulation and were judged to be more rewarding for caregivers. CONCLUSIONS. The absence of any differences between the exposed on nonexposed groups in the early neonatal period suggest that the better scores of exposed neonates at 1 month are traceable to the cultural positioning and social and economic characteristics of mothers using marijuana that select for the use of marijuana but also promote neonatal development (AU)
