In 5 of the 6 large Dutch developmental cohorts investigated here, lower SES adolescents are underrepresented and higher SES adolescents overrepresented. With former studies clearly revealing differences between SES strata in adolescent social competence and behavioral control, this misrepresentation may contribute to an overestimation of normative adolescent competence. Using a raking procedure, we used national census statistics to weigh the cohorts to be more representative of the Dutch population. Contrary to our expectations, in all cohorts, little to no differences between SES strata were found in the two outcomes. Accordingly, no differences between weighted and unweighted mean scores were observed across all cohorts. Furthermore, no clear change in correlations between social competence and behavioral control was found. These findings are most probably explained by the fact that measures of SES in the samples were quite limited, and the low SES participants in the cohorts could not be considered as representative of the low SES groups in the general population. Developmental outcomes associated with SES may be affected by a raking procedure in other cohorts that have a sufficient number and sufficient variation of low SES adolescents.

在这里调查的6个大型荷兰发展队列中，有5个中，低SES青少年的比例不足，而高SES青少年的比例较高。以前的研究清楚地揭示了SES阶层在青少年社交能力和行为控制方面的差异，这种失实陈述可能会导致高估规范性青少年能力。通过使用抽签程序，我们使用了国家人口普查统计数据来权衡队列，以更能代表荷兰人口。与我们的预期相反，在所有队列中，两个结局之间在SES层之间几乎没有差异。因此，在所有队列中均未观察到加权和未加权平均得分之间的差异。此外，没有发现社交能力与行为控制之间的相关性有明显变化。这些发现很可能是由于样本中SES的测量非常有限的事实所解释，并且队列中低SES参与者不能被视为普通人群中低SES群体的代表。与SES相关的发育结局可能受其他队列中具有足够数量和足够低SES青少年变化的其他队列中的倾斜程序的影响。
