Psychophysiological responses underlying unresolved loss and trauma in the Adult Attachment Interview / Lianne BAKKUM in Development and Psychopathology, 34-1 (February 2022)

Titre : Psychophysiological responses underlying unresolved loss and trauma in the Adult Attachment Interview Type de document : Texte imprimé et/ou numérique Auteurs : Lianne BAKKUM, Auteur ; Mirjam OOSTERMAN, Auteur ; Marije L. VERHAGE, Auteur ; Florentina C. KUNSELER, Auteur ; Richard M. PASCO FEARON, Auteur ; Carlo SCHUENGEL, Auteur ; Robbie DUSCHINSKY, Auteur Article en page(s) : p.197-212 Langues : Anglais (eng) Mots-clés : adult attachment autonomic nervous system reactivity loss childhood abuse trauma recall Index. décimale : PER Périodiques Résumé : Unresolved loss/trauma in the context of the Adult Attachment Interview (AAI) has been theorised to result from dissociative processing of fear-related memories and ideas. To examine the plausibility of this model, this study tested hypothesised associations between unresolved loss/trauma and indicators of autonomic nervous system (ANS) reactivity. First-time pregnant women (N = 235) participated in the AAI while heart rate (interbeat interval; IBI) and indicators of parasympathetic reactivity (respiratory sinus arrhythmia; RSA) and sympathetic reactivity (pre-ejection period; PEP, skin conductance level; SCL) were recorded. Using multilevel modelling, ANS reactivity was examined in relation to topic (loss/trauma versus other questions); discussion of actual loss/trauma; classification of unresolved/disorganised; and unresolved responses during the interview. Responses to loss/trauma questions and discussion of loss were associated with respectively larger and smaller IBIs. There was no moderation by unresolved/disorganised status. Unresolved responses about loss were associated with smaller IBIs. Participants classified as unresolved/disorganised showed decreasing PEP and blunted SCL throughout the whole interview. The findings suggest that unresolved speech about loss co-occurs with physiological arousal, although the inconclusive findings regarding parasympathetic and sympathetic nervous system responses fail to clearly support the role of fear.

Langues : Anglais (eng) Mots-clés : Ambiguity Autism spectrum disorder Decision-making Gain Loss Risk Uncertainty Index. décimale : PER Périodiques Résumé : Although the ability to make optimal decisions under uncertainty is an integral part of everyday life, individuals with autism spectrum disorder (ASD) frequently report that they experience difficulties with this skill. In behavioral economics, researchers distinguish two types of uncertainty to understand decision-making in this setting: risk (known probabilities) and ambiguity (unknown probabilities). However, it remains unclear how individuals with ASD behave under risk and ambiguity, despite growing evidence of their altered decision-making under uncertainty. We therefore extended previous research by studying the attitudes of those with ASD toward risk and ambiguity in both positive and negative contexts (i.e., gain and loss). In gain contexts, no significant difference was observed between the groups in risk attitudes, but ambiguity aversion was attenuated in ASD. In loss contexts, ambiguity attitudes did not significantly differ between the groups, but the ASD participants were less risk-seeking compared with the controls. In addition, insensitivity to the context change under risk and ambiguity in ASD was both significantly associated with poor social skills. These results improve our understanding of altered decision-making under uncertainty by disentangling the attitudes toward risk and ambiguity in ASD individuals. Applying behavioral economic tools may provide insights into the mechanisms underlying behavioral disturbances in ASD.

BAIN, Auteur Article en page(s) : p.102326 Mots-clés : Gastrointestinal Autism Spectrum Regression Loss Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) can present with developmental regression. In this study, we hypothesize an association between Gastrointestinal (GI) symptoms and regression. We conducted a two-part analysis using data from the Simon Simplex Collection consisting of 2564 ASD probands. Independent sample t-tests or chi-squared tests were utilized comparing regression against no-regression groups, and regression in children with and without early onset of GI symptoms. The presence of GI symptoms of any kind is associated with regression (odds ratio= 1.51; 95% CI 1.25 - 2.82; p < 0.001). Early GI effects on subsequent development of regression demonstrate no association (OR=0.81; 95% CI 0.649?1.01; p < 0.062). Although a clear relationship between GI symptoms and regression is demonstrated in this study, the lack of temporal relationship between the two highlight the need for a better understanding of the underlying mechanism behind this phenomenon.
