This study examined the driving behavior of 42 parent-teenager dyads for 18 months, under naturalistic driving conditions. At baseline participants' personality characteristics were assessed. Objective risky driving measures (kinematic risky driving) were captured by accelerometers for the duration of the study. To estimate teenage and parent correlations in kinematic risky driving, separate Poisson regression models were fit for teenagers and parents. Standardized residuals were computed for each trip for each individual. Correlations were obtained by estimating the Spearman rank correlations of the individual average residuals across teenagers and parents. The bootstrap technique was used to estimate the standard errors associated with the parent-teenager correlations. The overall correlation between teenage and parent kinematic risky driving for the 18-month study period was positive, but weak (r=0.18). When the association between parent and teenagers' risky driving was adjusted for shared personality characteristics, the correlation reduced to 0.09. Although interesting, the 95% confidence intervals on the difference between these two estimates overlapped zero. We conclude that the weak similarity in parent-teen kinematic risky driving was partly explained by shared personality characteristics.
本研究在自然驾驶条件下，对 42 对亲子进行了 18 个月的驾驶行为研究。在基线时评估了参与者的个性特征。通过加速度计在研究期间捕获客观的危险驾驶指标（运动学危险驾驶）。为了估计青少年和父母在运动学危险驾驶方面的相关性，分别为青少年和父母拟合泊松回归模型。为每个人的每次行程计算了标准化残差。通过估计青少年和父母个体平均残差之间的 Spearman 秩相关系数来获得相关性。使用自举技术估计与亲子相关性相关的标准误差。在 18 个月的研究期间，青少年和父母之间的运动学危险驾驶的总体相关性为正，但较弱（r=0.18）。当将父母与青少年危险驾驶之间的关联调整为共享个性特征时，相关性降低至 0.09。虽然有趣，但这两个估计值之间差异的 95%置信区间重叠为零。我们得出结论，父母与青少年在运动学危险驾驶方面的微弱相似性部分归因于共同的个性特征。
