Background: Stockholm syndrome or traumatic bonding (Painter & Dutton, Patterns of emotional bonding in battered women: Traumatic bonding. International Journal of Women's Studies , 8 (4), 363-375, 1985) has been used in mainstream culture, legal, and some clinical settings to describe a hypothetical phenomenon of trauma survivors developing powerful emotional attachments to their abuser. It has frequently been used to explain the reported 'positive bond' between some kidnap victims and their captor's, although scarce empirical research has supported this assertion...

INTRODUCTION: Disasters can be traumatic with a profound and lasting impact on individuals. During the COVID-19 pandemic, our team developed the Mindful Living Group (MLG) activities manual based on Eastern body-mind wisdom and Western trauma healing theory to provide psychological assistance for trauma healing. METHODS: In this study, we introduce a framework developed for the 10-session MLG activities manual, which consists of three core modules. Thirty-one participants living all over the country who had experienced traumatic stress resulting from the COVID-19 pandemic received the MLG intervention...

The collision of physician burnout and the collective trauma related to the COVID-19 pandemic warrants unique consideration in the conversation in regards to personal transformation. This article examines pathways to heal burnout and trauma through the lens of polyvagal theory and examines the post-traumatic growth theory as it relates to personal growth.

Recent efforts to improve marital therapy interventions have begun investigating psychophysiologic processes in therapy. These studies are novel and represent initial investigations into relevant phenomena associated with the therapy process. Grounded in Polyvagal Theory, this study introduces an on-going multimethod couple therapy process research (CHAMPS) and highlights the importance of establishing norms among distressed couples in therapy, which can provide context for other studies' results and instigate further investigation of physiology in marital therapy...

Research shows the disruptive effects of early maltreatment on the autonomic nervous system (ANS) functioning in adulthood. Psychotherapists not only tend to report higher rates of personal experience with early maltreatment, but also fewer mental problems and disturbances in adulthood, as compared to other professions. However, the role of the ANS in these processes has been understudied despite the relevance of the therapist's psychological state and related nonverbal communication for the therapeutic alliance...

Heart rate variabfility (HRV) has been a focal point throughout my academic history. To put into perspective, I have published studies spanning seven decades focusing on HRV (1969-2022). My interest in HRV started early in graduate school and continues to be an important portal informing my theoretical perspective. The current paper tracks some of this history, which started as an empirical observation and moved through several scientific stages including development of quantitative methods and investigations of neural mechanisms...

Porges ( Psychological Trauma: Theory, Research, Practice, and Policy , Advanced Online Publication, Jul 18, 2022, np). In the original article, the first name of Jacek Kolacz was misspelled as "Jakec" in the author byline and twice in the acknowledgments...

Due to its pivotal role in autonomic networks and interoception, the vagus attracts continued interest from both basic scientists and therapists of various clinical disciplines. In particular, the widespread use of heart rate variability as an index of autonomic cardiac control and a proposed central role of the vagus in biopsychological concepts, e.g., the polyvagal theory, provide a good opportunity to recall basic features of vagal anatomy. In addition to the "classical" vagal brainstem nuclei, i.e., dorsal motor nucleus, nucleus ambiguus and nucleus tractus solitarii, the spinal trigeminal and paratrigeminal nuclei come into play as targets of vagal afferents...

Primary school students suffer from high levels of anxiety and stress. Having emotional regulation abilities can help them to manage challenging emotional situations. Conscious and slow breathing is a physiological, emotional regulation strategy that is feasible for primary school students to learn. Following Polyvagal Theory and PMER Theory, this research presents the results of a breath-focused heart rate variability biofeedback intervention. The intervention aimed to reduce anxiety and physiological and social stress in primary school children...

The polyvagal theory, proposed by Stephen Porges, describes the adaptive responses of the mammalian autonomic nervous system. According to this novel theory, the vagus nerve functions through two independent pathways, referred to as the ventral and the dorsal vagal pathways. The ventral vagus is a myelinated nerve that has newly emerged in mammals and in coordination with cranial nerves regulates the muscles of the face and head to form the ventral vagal complex, which enables social engagement via exchange of safety cues and downregulating sympathetic defense reaction...

Hospitals provide the vast majority of cancer care. A necessary focus on survival has meant that they are less well-developed in terms of supporting patients with the emotional impact of cancer; and in supporting the frontline staff who contend with this. An integration of psychotherapeutic and neurobiological findings is used to develop an understanding of the patient-staff relationship and impact of high levels of distress within it. This includes reference to Transference and Countertransference, Mirror Neurons and Poly Vagal Theory...

OBJECTIVE: Psychological safety is increasingly recognized as central to mental health, wellbeing and posttraumatic growth. To date, there is no psychometrically supported measure of psychological safety combining psychological, physiological and social components. The current research aimed to develop and establish the neuroception of psychological safety scale (NPSS), informed by Polyvagal Theory. METHOD: The study comprised of 3 stages: (a) item generation, (b) item reduction, and (c) assessment of factor structure and internal consistency...

As a result of evolution, human babies are born with outstanding abilities for human communication and cooperation. The other side of the coin is their great sensitivity to any clear and durable violation in their relationship with caregivers. Infant sustained social withdrawal behavior (ISSWB) was first described in infants who had been separated from their caregivers, as in Spitz's description of "hospitalism" and "anaclitic depression." Later, ISSWB was pointed to as a major clinical psychological feature in failure-to-thrive infants...

Mammals show clear changes in heart rate linked to lung ventilation, characterized as respiratory sinus arrhythmia (RSA). These changes are controlled in part by variations in the level of inhibitory control exerted on the heart by the parasympathetic arm of the autonomic nervous system (PNS). This originates from preganglionic neurons in the nucleus ambiguous that supply phasic, respiration-related activity to the cardiac branch of the vagus nerve, via myelinated, efferent fibres with rapid conduction velocities...

A polyvagal perspective clarifies the neurobiological and biobehavioral shifts that occurred during evolutionary transition from asocial reptiles to social mammals. This transition enabled mammals, unlike their reptilian ancestors, to derive a biological benefit from social interactions. This innovation enabled social behavior to function as a neuromodulator that could efficiently regulate and optimize autonomic function to support homeostatic processes. This journey is highlighted by the phylogenetic transition during which the autonomic nervous system was repurposed to suppress defensive strategies to support and express sociality...

Childhood maltreatment history may influence autonomic reactivity and recovery to stressors. Hypothetically, the maltreatment history may contribute to a retuned autonomic nervous system that is reflected in a novel metric, vagal efficiency (VE), designed to assess the functional efficiency of vagal cardioinhibitory pathways on heart rate. We explored whether VE mediates the well-documented relationship between maltreatment history and psychiatric symptoms. We also investigated the relationship between measures of autonomic regulation in response to the physical and emotional challenges and psychiatric symptoms...

Contemporary strategies for health and wellbeing fail our biological needs by not acknowledging that feelings of safety emerge from internal physiological states regulated by the autonomic nervous system. The study of feelings of safety has been an elusive construct that has historically been dependent upon subjectivity. Acknowledging that feelings of safety have a measurable underlying neurophysiological substrate would shift investigations of feelings of safety from a subjective to an objective science. Polyvagal Theory provides an innovative scientific perspective to study feelings of safety that incorporates an understanding of neuroanatomy and neurophysiology...
