In order to assess stability and change in mother-infant interaction, 74 mother-infant dyads were observed at home under naturalistic conditions when infants were 1, 3, and 9 months. Both conceptually and empirically guided data-reduction procedures indicated that 4 summary constructs underlie 15 behavioral categories coded: reciprocal interaction, noninvolvement, distress, and basic care. Mean levels of reciprocal interaction remained unchanged over time, with individual differences being stable. Mean levels of noninvolvement increased from 1 to 3 months only, and remained stable across all time periods, while mean levels of distress and basic care declined linearly across the 9-month periods, with individual dyads displaying little stability. A final analysis assessed stability and change in the 9 component variables comprising the reciprocal interaction construct. Significant change was discerned with respect to several of these components, as well as a good deal of instability. These findings led to the conclusion that, in the face of sameness in mother-infant interaction across the first 9 months, there is also much change.
为了评估母婴互动的稳定性和变化情况，研究人员在婴儿1个月、3个月和9个月大时，于自然环境下对74对母婴进行了家庭观察。从概念和实证两方面指导的数据简化程序表明，15个行为类别编码背后存在4个概括性结构：相互互动、不参与、痛苦和基本照料。相互互动的平均水平随时间保持不变，个体差异稳定。不参与的平均水平仅在1至3个月时有所增加，在所有时间段内保持稳定，而痛苦和基本照料的平均水平在9个月期间呈线性下降，各母婴对之间几乎没有稳定性。最终分析评估了构成相互互动结构的9个组成变量的稳定性和变化情况。在其中几个组成部分中发现了显著变化，以及大量的不稳定性。这些发现得出的结论是，尽管在前9个月母婴互动存在相同性，但也存在很多变化。
