Innovative approaches in investigating inter-beat intervals: Graph theoretical method suggests altered autonomic functioning in adolescents with ADHD
Kvadsheim, Elisabet; Fasmer, Ole Bernt; Fasmer, Erlend Eindride; Hauge, Erik Rønneberg; Thayer, Julian F.; Osnes, Berge; Haavik, Jan; Koenig, Julian; Adolfsdottir, Steinunn; Plessen, Kerstin J.; Sørensen, Lin (Journal article; Peer reviewed, 2022)Cardiac inter-beat intervals (IBIs) are considered to reflect autonomic functioning and self-regulatory abilities and are often investigated by traditional time- and frequency domain analyses. These analyses investigate ... -
Lower Cardiac Vagal Activity Predicts Self-Reported Difficulties With Emotion Regulation in Adolescents With ADHD
Kvadsheim, Elisabet; Fasmer, Ole Bernt; Osnes, Berge; Koenig, Julian; Adolfsdottir, Steinunn; Eichele, Heike; Plessen, Kerstin Jessica; Sørensen, Lin (Journal article; Peer reviewed, 2020)Objective: To investigate the relation between cardiac vagal activity (CVA), a measure of autonomic nervous system (ANS) flexibility, and self-reported emotion regulation (ER) difficulties in adolescents with attention-d ... -
Suboptimal decision making and interpersonal problems in ADHD: longitudinal evidence from a laboratory task
Sørensen, Lin; Adolfsdottir, Steinunn; Kvadsheim, Elisabet; Eichele, Heike; Plessen, Kerstin J.; Sonuga-Barke, E. (Journal article; Peer reviewed, 2024)Over half of children with Attention-Deficit/Hyperactivity Disorder (ADHD) display interpersonal and social problems. Several lines of research suggest that suboptimal decision making, the ability to adjust choices to ... -
Vagally mediated heart rate variability, stress, and perceived social support: a focus on sex differences
Kvadsheim, Elisabet; Sørensen, Lin; Fasmer, Ole Bernt; Osnes, Berge; Haavik, Jan; Williams, DeWayne P.; Thayer, Julian Francis; Koenig, Julian (Journal article; Peer reviewed, 2022)Higher vagally mediated heart rate variability (vmHRV), reflecting vagal activity as indexed by heart function and lower stress vulnerability, is associated with higher perceived social support. Seeking social support is ... -
Variability and similarity of inter-beat intervals of the heart as markers of perceived stress and behavioral regulation
Kvadsheim, Elisabet (Doctoral thesis, 2022-08-16)The current dissertation investigated inter-beat interval (IBI) indices of variability and similarity, reflecting autonomic nervous system (ANS) modulation on heart rate. IBI indices of cardiac vagal activity (CVA) are ...
