Growing evidence supports the hypothesis that temperamental traits are not static throughout adolescence. The known links between both reactive and regulatory temperament and anxiety symptoms should be investigated bearing this hypothesis in mind. This study collected self-reported data on behavioral inhibition system (BIS) sensitivity, attentional control (AC), and anxiety symptomatology, from 296 adolescents (64.

Article Synopsis
  • The study investigates non-linear cardiac measures, such as scale-invariant self-similarity and entropy, alongside traditional heart rate variability (HRV), in 55 healthy adolescents during positive and negative interactions with their mothers.
  • Results revealed significant changes in cardiac complexity during stressful interactions, suggesting that adolescents' heart rate responses become less complex when facing negative situations.
  • Although sex differences were explored, no significant effects were found, although trends indicated lower cardiac scaling in females compared to males, highlighting the need for further research on sex differences in cardiac responses.

This paper aimed to (a) validate a novel technique that quantifies the length of the trajectories the cardiac system follows within a two-dimensional state-space, and (b) test its usefulness to better understand how cognitive emotion regulation (CER) style is associated with cardiac output. A positive CER style was assessed in a sample of healthy adolescents (n = 57), and mean and total distances, in addition to heart rate variability (HRV) measures and cardiac entropy (SampEn), were calculated during a conflict discussion with the adolescents' mothers. Associations between distances and HRV measures in time and frequency-domains and SampEn were examined to better understand the physiological meaning of distances; further, whether a positive CER style would predict distances, HRV, and SampEn.

Adolescence is a vulnerable period in terms of the onset of anxiety disorders, and dyadic parent-adolescent interactions may play a key role in either increasing or reducing the risk of psychopathologies. This study examines the presence of physiological synchrony (specifically, linkage in interbeat interval series) and non-verbal synchrony in positive and negative interactions between adolescents (aged 13-16) and their fathers. Non-verbal synchrony was quantified through the coordination of the interactants' body movements, using an automated video-analysis algorithm (motion energy analysis).

Background: Anxiety disorders frequently have an onset during adolescence, which when left untreated could lead to a chronic course and outcome. This study aimed to examine the way in which a cognitive behaviour therapy-based programme (Super Skills for Life - adolescent version; SSL-A) could change the course of anxiety symptoms through adolescent's behavioural performance and cardiac function.

Method: Sixty-one adolescents at risk of developing an anxiety disorder (45.
