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)

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.

Impact trajectories of childhood maltreatment duration on affective and social development / Martina ARDIZZI in Development and Psychopathology, 37-3 (August 2025)  

Public ISBD [article]  inDevelopment and Psychopathology > 37-3 (August 2025) . - p.1405-1415 Titre : Impact trajectories of childhood maltreatment duration on affective and social development Type de document : texte imprimé Auteurs : Martina ARDIZZI, Auteur ; Roberto RAVERA, Auteur ; Maria Alessandra UMILTÀ, Auteur ; Francesca FERRONI, Auteur ; Silvia AMPOLLINI, Auteur ; Jacek KOLACZ, Auteur ; Stephen W. PORGES, Auteur ; Vittorio GALLESE, Auteur Article en page(s) : p.1405-1415 Langues : Anglais (eng) Mots-clés : Autonomic regulation  duration  emotions  facial mimicry  maltreatment Index. décimale : PER Périodiques Résumé : Childhood maltreatment (CM) deeply impacts victims' social competences. The aim of the present study was to investigate the effect that CM duration exerts on victims' affective and social development testing three different impact trajectories (i.e., linear, logarithmic and quadratic) and its physiological (facial mimicry and autonomic regulation of the heart) and behavioral (percentage of anger recognition false alarm) markers. In a cross-sectional design, 73 Sierra Leonean youths (all males, 5-17 years old) were enrolled in the study. Of those, 36 were homeless all abandoned at the age of 4 and exposed to CM, whereas 37 were controls. Only physiological markers of affective development were influenced by CM duration. A quadratic relation between the autonomic regulation recorded at rest and CM duration was found, indicating initial physiological compensation followed by progressive autonomic withdrawal. Furthermore, CM duration was associated to a specific linear decrease of facial mimicry and vagal regulation in response to angry and sad facial expressions whereas no influences were detected for happy and fearful faces. The results of the present study provide insightful clues on victims' natural patterns of resilience, deterioration, and chronicity, allowing a deeper comprehension of the developmental pathways through which early life adversities place youths on a track of lifelong health disparities.

The neurophysiological embedding of child maltreatment / Steven J. HOLOCHWOST in Development and Psychopathology, 33-3 (August 2021)  

Public ISBD [article]  inDevelopment and Psychopathology > 33-3 (August 2021) . - p.1107-1137 Titre : The neurophysiological embedding of child maltreatment Type de document : texte imprimé Auteurs : Steven J. HOLOCHWOST, Auteur ; Guan WANG, Auteur ; Jacek KOLACZ, Auteur ; W. Roger MILLS-KOONCE, Auteur ; J. Bart KLIKA, Auteur ; Sara R. JAFFEE, Auteur Article en page(s) : p.1107-1137 Langues : Anglais (eng) Mots-clés : autonomic nervous system  hypothalamic–pituitary–adrenal (HPA) axis  maltreatment  neurophysiology  cortisol Index. décimale : PER Périodiques Résumé : Maltreatment adversely impacts the development of children across a host of domains. One way in which maltreatment may exert its deleterious effects is by becoming embedded in the activity of neurophysiological systems that regulate metabolic function. This paper reviews the literature regarding the association between childhood maltreatment and the activity of three systems: the parasympathetic nervous system, the sympathetic nervous system, and the hypothalamic–pituitary–adrenal axis. A particular emphasis is placed on the extent to which the literature supports a common account of activity across these systems under conditions of homeostasis and stress. The paper concludes with an outline of directions for future research and the implications of the literature for policy and practice.
