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