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-deficit/hyperactivity disorder (ADHD) and controls.
The sample comprised 11-17-year-old adolescents with ADHD (=34) and controls ( = 33). Multiple linear regression analyses investigated the relation between CVA, as indexed by high frequency heart rate variability (HF-HRV), and ER difficulties as assessed by the Difficulties in Emotion Regulation Scale (DERS). Supplemental analyses were performed in ADHD and control groups separately. Analyses assessed effects of body mass index (BMI), physical activity levels, and HF peak as a surrogate of respiration on CVA.
Lower CVA was associated with ER difficulties, and specifically with limited access to effective ER strategies. When investigating the relation between CVA and ER in the ADHD and control groups separately, there was a tendency of lower CVA predicting limited access to effective ER strategies in the ADHD group, and not in the control group.
The results suggest that lower CVA, i.e., reduced ANS flexibility, in adolescents with ADHD and controls is associated with self-reported ER difficulties, and specifically with limited access to effective ER strategies. There was a tendency for lower CVA to predict limited ER strategies only in the adolescents with ADHD and not controls.
探讨心脏迷走神经活动（CVA）（一种自主神经系统（ANS）灵活性的指标）与注意力缺陷多动障碍（ADHD）青少年及对照组自我报告的情绪调节（ER）困难之间的关系。
样本包括11至17岁的ADHD青少年（=34）和对照组（=33）。多元线性回归分析研究了以高频心率变异性（HF-HRV）为指标的CVA与通过情绪调节困难量表（DERS）评估的ER困难之间的关系。分别在ADHD组和对照组中进行了补充分析。分析评估了体重指数（BMI）、身体活动水平以及作为呼吸替代指标的HF峰值对CVA的影响。
较低的CVA与ER困难相关，特别是与有效ER策略的获取受限有关。当分别研究ADHD组和对照组中CVA与ER之间的关系时，在ADHD组中存在较低的CVA预测有效ER策略获取受限的趋势，而在对照组中则不存在。
结果表明，ADHD青少年及对照组中较低的CVA，即ANS灵活性降低，与自我报告的ER困难相关，特别是与有效ER策略的获取受限有关。仅在ADHD青少年而非对照组中存在较低的CVA预测ER策略受限的趋势。
