Research shows the disruptive effects of early maltreatment on the autonomic nervous system (ANS) functioning in adulthood. Psychotherapists 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...

Background Because there is a relationship between mental health (MH) and medical adversity and autonomic dysregulation, we hypothesized that individuals infected with COVID-19 would report greater current autonomic reactivity and more MH difficulties (emotional distress, mindfulness difficulties, and posttraumatic stress). We also hypothesized tha...

The growing population of adults with congenital heart disease (CHD) often have lifelong experience of dealing with potentially traumatic health crises and medical uncertainty whilst facing increased vulnerability to post-traumatic stress disorder (PTSD). The COVID-19 pandemic presents additional challenges for this population including increased r...

Objective Autonomic regulation of organ and tissues may give rise to disruptions of typical functions. The Body Perception Questionnaire Short Form (BPQ-SF) includes items that were developed to assess autonomic symptoms in daily life. This pair of studies aimed to establish previously unexplored psychometric properties of the BPQ-SF, develop norma...

Objectives: The growing population of adults with congenital heart disease (CHD) often have lifelong experience of dealing with potentially traumatic health crises and medical uncertainty. Further, they can face increased vulnerability to anxiety, depression and PTSD. The COVID-19 pandemic may present additional challenges for this population inclu...

Abstract Background: Adults with congenital heart disease (CHD) have lifelong experience of dealing with potentially traumatic health crises and show increased vulnerability to anxiety, depression and PTSD. The COVID-19 pandemic presents a further challenge for the CHD population who face greater risk of serious complications from the virus, psycho...

Background: The spread of the COVID-19 virus presents an unprecedented event that rapidly introduced widespread life threat, economic destabilization, and social isolation. The human nervous system is tuned to detect safety and danger, integrating body and brain responses via the autonomic nervous system. Shifts in brain-body states toward danger r...
