The aim of the study is to identify factors influencing infants' crying behaviour (total crying duration, length of crying bouts, and frequency of crying). The searching for variables explaining inter-individual differences requires a sufficient stability of the cry parameters at least over short time intervals. Thus, a second aim is to assess the intra-individual stability of the crying behaviour in an age range from 3 to 12 months. Sixty-two mother-child dyads participated in the study. The results show substantial stabilities of the crying behaviour of infants between 3 and 12 months of age. This is related to the amount of crying as well as to the pattern of crying shown by the children over a 24 h interval. The typical cry pattern is characterized by peaks at 12.00 h and early in the evening, although there are large individual differences between the children with regard to cry durations at each hour of the day. Regarding the cry durations at 3 months of age, birth complications and the perceived emotional atmosphere in the mothers' family of origin are the major contributing factors.
本研究的目的是确定影响婴儿哭闹行为的因素（总哭闹时长、哭闹发作时长以及哭闹频率）。寻找能够解释个体差异的变量需要哭闹参数至少在短时间间隔内具有足够的稳定性。因此，第二个目的是评估3至12个月龄婴儿哭闹行为的个体内稳定性。62对母婴参与了该研究。结果显示，3至12个月龄婴儿的哭闹行为具有显著的稳定性。这与哭闹量以及儿童在24小时内的哭闹模式有关。典型的哭闹模式表现为中午12点和傍晚早些时候出现高峰，尽管不同儿童在一天中每个小时的哭闹时长存在很大个体差异。关于3个月龄时的哭闹时长，出生并发症以及母亲原生家庭中感知到的情感氛围是主要影响因素。
