The present study investigated physiological synchrony in the parasympathetic nervous system among fathers, mothers, and adolescents during a real‐time family interaction, and child characteristics that may moderate the level of physiological synchrony. Our sample consisted of 191 families with adolescents (M_age = 12.4 years) and both of their parents, who participated in a triadic family conflict discussion. During the discussion, respiratory sinus arrhythmia (RSA) was measured for all three family members. Multilevel analysis indicated a significant positive concurrent synchrony between adolescents and their mothers, as well as between fathers and mothers on a minute‐to‐minute basis. No RSA synchrony was found between adolescents and their fathers. Furthermore, adolescent emotional insecurity significantly moderated mother‐adolescent RSA synchrony. Whereas adolescents with low emotional insecurity exhibited positive synchrony with their mothers, no synchrony was observed when adolescent emotional insecurity was high. In conclusion, findings of the present study illuminate the patterns of RSA synchrony among parents and adolescents and highlight a link between adolescent emotional insecurity and attenuated mother‐adolescent physiological synchrony.

父母-青少年生理同步：青少年情绪不安全感的调节作用。

本研究调查了父亲，母亲和青少年之间在实时家庭互动中副交感神经系统中的生理同步性，以及可能减缓生理同步性水平的儿童特征。我们的样本包括191个青少年家庭（M_年龄） = 12.4岁）和他们的父母（参加了三元家庭冲突讨论）。在讨论中，对所有三个家庭成员的呼吸窦性心律不齐（RSA）进行了测量。多级分析表明，青少年与母亲之间以及父亲与母亲之间每分钟之间都有显着的积极并发同步。青少年与父亲之间未发现RSA同步。此外，青春期的情绪不安全感明显减轻了母亲-青少年RSA的同步性。情绪不安全感低的青少年与母亲表现出积极的同步性，而青少年情绪不安全感高的青少年则没有同步性。结论，
