这项研究旨在分析参与五项针对行为问题的儿童预防性干预试验的参与者在儿童和青少年时期冲动增长的人之间的异质性。此外,我们旨在测试与成人精神病理学相关的个人资料成员资格。代表2、4、5、7、8和10年级冲动行为的测量项目,以及攻击性,物质使用,自杀意念/企图,和成年期的焦虑/抑郁从五项试验中整合(N=4,975)。我们对这个样本应用了潜在的类增长分析,以及样本分为非干预(n=2,492)和干预(n=2,483)参与者。在所有样品中,剖面的特点是高,中度,低,和低增加的冲动水平。关于成人的结果,在所有样品中,高,中度,与低调相比,低调认可了更高的攻击性。在自杀意念/企图和焦虑/抑郁方面,样本和资料之间存在细微差别。在样品中,药物使用情况之间没有显著差异.总的来说,我们的研究有助于了解冲动性的发展过程和预后,以及增加协作努力将多项研究中的数据联系起来,以更好地了解发展过程。
This study aimed to parse between-person heterogeneity in growth of impulsivity across childhood and adolescence among participants enrolled in five childhood preventive intervention trials targeting conduct problems. In addition, we aimed to test profile membership in relation to adult psychopathologies. Measurement items representing impulsive behavior across grades 2, 4, 5, 7, 8, and 10, and aggression, substance use, suicidal ideation/attempts, and anxiety/depression in
adulthood were integrated from the five trials (N = 4,975). We applied latent class growth analysis to this sample, as well as samples separated into nonintervention (n = 2,492) and intervention (n = 2,483) participants. Across all samples, profiles were characterized by high, moderate, low, and low-increasing impulsive levels. Regarding adult outcomes, in all samples, the high, moderate, and low profiles endorsed greater levels of aggression compared to the low-increasing profile. There were nuanced differences across samples and profiles on suicidal ideation/attempts and anxiety/depression. Across samples, there were no significant differences between profiles on substance use. Overall, our study helps to inform understanding of the developmental course and prognosis of impulsivity, as well as adding to collaborative efforts linking data across multiple studies to better inform understanding of developmental processes.
