However, directions of effects remain unclear. This study examined associations between aspects of HPA axis reactivity, anxiety, and externalizing problems over two years by early PTE exposure history, while statistically capturing the co-occurrence of symptom domains. Youth (N = 189; Mage = 10.96 years, SD = 2.51, Range = 8–15; 52.4% female, 47.1% male; 50.3% White, 35.4% Black/African American, 6.4% Other; 7.4% Hispanic/Latine) were included if they had early PTE exposure (n = 107) or had never experienced a PTE (n = 82). HPA axis reactivity to social stress was calculated using area under the curve with respect to ground (AUCg) and increase (AUCi). For youth with early PTE exposure, higher AUCg was concurrently associated with more externalizing symptoms and greater predominance of externalizing over anxiety. Blunted AUCi predicted increasing predominance of externalizing for the early PTE group, but elevated AUCi predicted increases in anxiety for the no PTE group. Findings highlight distinct roles of overall and reactive HPA axis functioning in shaping outcomes following early trauma.

Stress reactivity and social cognition in pure and co-occurring early childhood relational bullying and victimization / Gretchen R. PERHAMUS in Development and Psychopathology, 34-4 (October 2022)  

Public ISBD [article]  inDevelopment and Psychopathology > 34-4 (October 2022) . - p.1300-1312 Titre : Stress reactivity and social cognition in pure and co-occurring early childhood relational bullying and victimization Type de document : texte imprimé Auteurs : Gretchen R.

Co-occurring and pure relational bullying and victimization experiences were measured using a dimensional bifactor model, aiming to address methodological limitations of categorical approaches, using data from 300 preschoolers (M(age) = 44.70 months, SD = 4.38). Factor scores were then saved and used in nested path analyses with a subset of participants (n = 81) to test main study hypotheses regarding effects of HAB and skin conductance level reactivity (SCL-R). Bifactor models provided good fit to the data at two independent time points. HAB and SCL-R interacted to predict increases in co-occurring relational bullying/victimization with evidence for over- and underarousal pathways.

The development of forms and functions of aggression during early childhood: A temperament-based approach / Jamie M. OSTROV in Development and Psychopathology, 35-2 (May 2023)  

Public ISBD [article]  inDevelopment and Psychopathology > 35-2 (May 2023) . - p.941-957 Titre : The development of forms and functions of aggression during early childhood: A temperament-based approach Type de document : texte imprimé Auteurs : Jamie M.

MEMBA, Auteur ; Sarah PROBST, Auteur Article en page(s) : p.941-957 Langues : Anglais (eng) Mots-clés : aggression  development  early childhood  gender  temperament Index. décimale : PER Périodiques Résumé : This study used a short-term longitudinal design with theoretically derived preregistered hypotheses and analyses to examine the role of temperament in the development of forms (i.e., physical and relational) and functions (i.e., proactive and reactive) of aggressive behavior in early childhood (N = 300, M age = 44.70 months, SD = 4.38, 44% girls). Temperament was measured via behavioral reports of emotional dysregulation, fearlessness/daring, and rule internalization/empathy and, in a subsample that completed a physiological assessment, via skin conductance and respiratory sinus arrhythmia. Emotion dysregulation generally served as a risk factor for all subtypes of aggression, with evidence of stronger associations with reactive as compared to proactive functions of relational aggression for girls. Daring predicted increases in physical aggression, especially among boys, and rule internalization predicted decreases in relational aggression, especially among girls. Rule internalization mediated longitudinal associations between daring and proactive relational aggression for girls. Some evidence also emerged supporting associations between adaptive functioning (i.e., high empathy, high respiratory sinus arrhythmia) and proactive functions of aggression. Findings highlight distinct temperamental risk factors for physical versus relational aggression and provide partial support for gender-linked theories of the development of aggression.
