The objectives of this study were to establish the different developmental trajectories of hyperactive-impulsive behaviors on the basis of both mother and father ratings at 19, 32, 50, and 63 months, and to examine the predictive validity of these trajectories with respect to later hyperactive-impulsive behaviors, as rated by teachers in the first 2 years of school. Hyperactive-impulsive behaviors were assessed in a population-based sample of 1,112 twins (565 boys and 547 girls) at 19, 32, 50, and 63 months of age. The results revealed a differentiated and consistent view of developmental trajectories of hyperactive-impulsive behaviors derived from these repeated assessments, with 7.1% of children seen by mothers (7% for fathers) as displaying high and stable hyperactive-impulsive behaviors. According to mother ratings, children on a high-chronic trajectory were more likely than other children to display hyperactive-impulsive behaviors at 72 and 84 months according to their teachers. Repeated measures over time and father-based trajectories significantly added to the prediction teacher later ratings of hyperactive-impulsive behaviors. These results support the predictive validity of parental assessment of hyperactive-impulsive behaviors during the preschool years and their use to identify children at risk for further evaluation and possible intervention.
本研究的目的是根据父母在孩子19、32、50和63个月时的评分，确定多动冲动行为的不同发展轨迹，并以前两年学校教师对孩子多动冲动行为的评分，检验这些轨迹的预测效度。在一个基于人群的包含1112对双胞胎（565名男孩和547名女孩）的样本中，于孩子19、32、50和63个月大时对其多动冲动行为进行了评估。结果显示，从这些重复评估中得出的多动冲动行为发展轨迹具有差异性且一致，母亲（父亲为7%）认为7.1%的孩子表现出高度且稳定的多动冲动行为。根据母亲的评分，处于高慢性轨迹的孩子在72和84个月时，比其他孩子更有可能被教师评定为表现出多动冲动行为。随着时间的重复测量以及基于父亲的轨迹显著增加了对教师后来评定的多动冲动行为的预测。这些结果支持了父母在学龄前对多动冲动行为评估的预测效度，以及利用这些评估来识别有进一步评估和可能干预风险的孩子。
