Abstract

Objective: Vagally-mediated heart rate variability (vmHRV) is regarded as transdiagnostic marker of emotion regulation and cognitive control capacity. We analysed vmHRV of children with attention deficit/hyperactivity disorder (ADHD). Based on previous research, we expected to find comorbid symptom dimensions (i.e. internalizing symptoms, conduct problems (CP), and callous unemotional (CU) traits) to relate to vmHRV measures. Methods: The sample comprised 100 (70 boys) medication naïve children with ADHD. Children were 6 to 11 years old. High frequency HRV (HF-HRV) was measured at rest and during a delay of gratification task. Additionally, sympathetic reactivity was assessed via skin conductance responses (SCR). Comorbid symptoms were assessed by parent-report questionnaires and clinical interviews. Results: The multiple correlation between CU traits and the HF-HRV scores proved statistically significant. Higher CU traits were associated with higher HRV resting-state and response scores. CP were positively associated with the SCR score. Conclusion: In children with ADHD, increased CU traits might point to a comparatively less impaired self-regulation capacity in the reward-related context. The result corresponds to findings from previous studies. In the future, CU traits should be considered in analyses of autonomic regulation in ADHD. [ABSTRACT FROM AUTHOR]

Abstract

Reflecting a decade of tremendous growth in mindfulness research and interventions, this authoritative handbook is now in a significantly revised second edition with 75% new material. The volume examines the interface of contemporary psychological science and ancient contemplative traditions. It presents cutting-edge work on the neurobiological, cognitive, emotional, and interpersonal mechanisms and effects of meditative practices. Chapters on exemplary applications review mindfulness-based interventions for both clinical and nonclinical populations. Contributors describe the development of and evidence base for each approach and identify important directions for future investigation. New to This Edition •Most chapters are new or extensively updated. •Chapters on emotion regulation processes and interventions for chronic pain. •Chapters on interventions in school and work settings. •Chapter on adapting mindfulness-based research and interventions for Black communities. •Chapters on neurophenomenology, process-based research, and Buddhist philosophy.
