Purpose

Both the resting heart rate (RHR) and the callous-unemotional (CU) traits have been associated with juvenile delinquency, however the effect of their interaction is not yet clear.

Methods

Four hundred and twenty-three institutionalized adolescents divided into early adolescents (10–14 years, n = 133), late adolescents (15–17 years, n = 286), and young adults (18–22 years, n = 136) participated in the study. RHR was measured using a wristband, and CU traits and delinquency history were assessed using self-reported questionnaires. Moderation analysis was performed to understand how the combination between RHR and CU is associated to offending.

Results

CU traits were associated with offending at all ages. The interactions between RHR and CU traits were significantly related to the likelihood of offending in the early and the late adolescent. The highest likelihood of offending is related to high CU traits combined with low RHR in early adolescents and with high RHR in late adolescents.

Conclusions

These findings provide further insight in the relationship between psychopathic traits and biophysiological maturation in explaining juvenile delinquency.

研究青少年犯罪中静息心率与冷酷无情特征之间的关系

目的

静息心率（RHR）和冷酷无情（CU）特征都与青少年犯罪有关，但它们相互作用的影响尚不清楚。

方法

423 名被收容的青少年参与了研究，分为青少年早期（10-14 岁，n  = 133）、青少年晚期（15-17 岁，n  = 286）和青年人（18-22 岁，n  = 136）在研究中。使用腕带测量 RHR，并使用自我报告的问卷评估 CU 特征和犯罪史。进行调节分析是为了了解 RHR 和 CU 之间的组合如何与违规相关。

结果

CU 特征与所有年龄段的犯罪行为相关。RHR 和 CU 特征之间的相互作用与青少年早期和晚期的犯罪可能性显着相关。犯罪的最高可能性与青少年早期的高 CU 特征与低 RHR 以及青少年晚期的高 RHR 相关。

结论

这些发现为解释青少年犯罪提供了关于精神病特征与生物生理成熟之间关系的进一步见解。
