Rethinking Resting Heart Rate Variability: No Evidence of Association With Self-Regulation and Psychopathology in a Cross-Sectional Study Among Adolescents in Colombia, Nepal, and South Africa.

ABSTRACT: Resting-state heart rate variability (HRV) has been proposed by some researchers as a potential transdiagnostic measure of psychopathology. It is often found to be reduced across a range of mental health conditions and is thought to reflect self-regulatory processes, which are often impaired in these conditions. However, most existing evidence is derived from high-income countries with limited ethnic variation. This leaves a critical gap in understanding whether these associations generalize to low- and middle-income countries (LMICs) or to individuals from under-represented ethnic backgrounds. In this cross-sectional study, we examined the relationship between resting-state HRV, self-regulation, and psychopathology in a large, diverse sample of 1107 adolescents aged 13-15 years living in
