The present study investigated physiological synchrony across mothers, fathers, and adolescents during a conflict discussion. In particular, a multilevel, within-dyad approach was used to parameterize synchrony within the parasympathetic nervous system. Moreover, we examined how domains of conflict within the larger family system influenced the level of synchrony between family members. Participants were 191 families with adolescents (M age = 12.4 years), whose respiratory sinus arrhythmia (RSA) were measured during a triadic family conflict discussion. On the minute-to-minute basis, mothers and adolescents as well as mothers and fathers exhibited positive RSA concurrent synchrony, whereas no such concordance was observed between adolescents and fathers. In addition, the presence of conflict between parents with respect to coparenting moderated the level of mother-adolescent synchrony such that no concordant RSA synchrony emerged between mother and adolescents under high levels of coparenting conflict. In contrast, general interparental conflict did not moderate levels of physiological synchrony among any of the dyads. Findings suggest that mothers may be particularly physiologically in tune with family members in the context of conflict discussions and specific domains of family conflict may influence concordant physiological dynamics. Taken together, this is one of the first studies to examine physiological synchrony during the adolescent period and results suggest this may be an important developmental period for these dynamics.

整合多层次方法来检查家庭冲突和父母-青少年生理同步性。

本研究调查了冲突讨论期间母亲、父亲和青少年之间的生理同步。特别是，使用了多层次、二元组内的方法来参数化副交感神经系统内的同步。此外，我们研究了更大的家庭系统内的冲突领域如何影响家庭成员之间的同步水平。参与者是 191 个有青少年的家庭（M 年龄 = 12.4 岁），他们的呼吸性窦性心律失常 (RSA) 在三方家庭冲突讨论中进行了测量。在每分钟的基础上，母亲和青少年以及母亲和父亲表现出积极的 RSA 同时同步，而在青少年和父亲之间没有观察到这种一致性。此外，父母之间在共同养育方面的冲突缓和了母亲-青少年同步的水平，因此在高水平的共同养育冲突下，母亲和青少年之间没有出现一致的 RSA 同步。相比之下，一般的父母间冲突并没有缓和任何二人之间的生理同步水平。研究结果表明，在讨论冲突的背景下，母亲可能在生理上与家庭成员特别协调，而家庭冲突的特定领域可能会影响一致的生理动态。综上所述，这是最早研究青少年时期生理同步性的研究之一，结果表明这可能是这些动态的重要发展时期。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
