Child maltreatment severity and sleep variability predict mother–infant RSA coregulation / Samantha M. BROWN in Development and Psychopathology, 33-5 (December 2021)

BROWN, Auteur ; Erika LUNKENHEIMER, Auteur ; Monique LEBOURGEOIS, Auteur ; Keri J.

Child maltreatment and sleep variability may reflect high-risk caregiving, but it is unknown whether they confer vulnerability for poorer mother–infant parasympathetic coordination. The aim of this study was to examine mother–infant coregulation of respiratory sinus arrhythmia (RSA) in relation to child maltreatment severity and night-to-night sleep variability in 47 low-income mother–infant dyads. Maternal and infant sleep was assessed with actigraphy and daily diaries for 7 nights followed by a mother–infant still-face procedure during which RSA was measured. Higher maltreatment severity was associated with weakened concordance in RSA coregulation related to the coupling of higher mother RSA with lower infant RSA, suggesting greater infant distress and lower maternal support. In addition, higher infant sleep variability was associated with infants’ lower mean RSA and concordance in lagged RSA coregulation such that lower maternal RSA predicted lower infant RSA across the still-face procedure, suggesting interrelated distress. The findings indicate that adverse caregiving environments differentially impact regulatory patterns in mother–infant dyads, which may inform modifiable health-risk behaviors as targets for future intervention.

Evaluating Sensory Processing in Fragile X Syndrome: Psychometric Analysis of the Brain Body Center Sensory Scales (BBCSS) / Jacek KOLACZ in Journal of Autism and Developmental Disorders, 48-6 (June 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-6 (June 2018) . - p.2187-2202 Titre : Evaluating Sensory Processing in Fragile X Syndrome: Psychometric Analysis of the Brain Body Center Sensory Scales (BBCSS) Type de document : texte imprimé Auteurs : Jacek KOLACZ, Auteur ; Melissa RASPA, Auteur ; Keri J.

PORGES, Auteur Article en page(s) : p.2187-2202 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Autonomic nervous system  Fragile X  Polyvagal theory  Psychometrics  Sensory processing Index. décimale : PER Périodiques Résumé : Individuals with fragile X syndrome (FXS), especially those co-diagnosed with autism spectrum disorder (ASD), face many sensory processing challenges. However, sensory processing measures informed by neurophysiology are lacking. This paper describes the development and psychometric properties of a parent/caregiver report, the Brain-Body Center Sensory Scales (BBCSS), based on Polyvagal Theory. Parents/guardians reported on 333 individuals with FXS, 41% with ASD features. Factor structure using a split-sample exploratory-confirmatory design conformed to neurophysiological predictions. Internal consistency, test-retest, and inter-rater reliability were good to excellent. BBCSS subscales converged with the Sensory Profile and Sensory Experiences Questionnaire. However, data also suggest that BBCSS subscales reflect unique features related to sensory processing. Individuals with FXS and ASD features displayed more sensory challenges on most subscales.

Sluggish vagal brake reactivity to physical exercise challenge in children with selective mutism / Keri J. HEILMAN in Development and Psychopathology, 24-1 (January 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-1 (January 2012) . - p.241-250 Titre : Sluggish vagal brake reactivity to physical exercise challenge in children with selective mutism Type de document : texte imprimé Auteurs : Keri J. HEILMAN, Auteur ; Sucheta D. CONNOLLY, Auteur ; Wendy O. PADILLA, Auteur ; Marika I. WRZOSEK, Auteur ; Patricia A. GRACZYK, Auteur ; Stephen W. PORGES, Auteur Année de publication : 2012 Article en page(s) : p.241-250 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Cardiovascular response patterns to laboratory-based social and physical exercise challenges were evaluated in 69 children and adolescents, 20 with selective mutism (SM), to identify possible neurophysiological mechanisms that may mediate the behavioral features of SM. Results suggest that SM is associated with a dampened response of the vagal brake to physical exercise that is manifested as reduced reactivity in heart rate and respiration. Polyvagal theory proposes that the regulation of the vagal brake is a neurophysiological component of an integrated social engagement system that includes the neural regulation of the laryngeal and pharyngeal muscles. Within this theoretical framework, sluggish vagal brake reactivity may parallel an inability to recruit efficiently the structures involved in speech. Thus, the findings suggest that dampened autonomic reactivity during mobilization behaviors may be a biomarker of SM that can be assessed independent of the social stimuli that elicit mutism.
