MyChild - Guilt

The Leiden Consortium on Individual Development (L-CID) study was founded by Marinus van IJzendoorn, Eveline Crone, Marian Bakermans-Kranenburg and Rutger Engels in 2013. It was developed as one of four work packages of the overarching Consortium on Individual Development (CID). The L-CID study is a large-scale longitudinal intervention study in which 500 families with same-sex twins are followed over a six year period. L-CID has a cohort-sequential design with two cohorts: an early childhood cohort (ECC), aged 3-4 at wave 1, and a middle childhood cohort (MCC), aged 7-8 at wave 1. Annual assessments consist of alternating lab- or home visits during which behavioral and neurobiological data are collected. The collected data allow, among others, for testing which child characteristics shape the effect of (manipulated) environmental factors. The aim of L-CID is twofold: 1. To investigate the development of social competence and behavioral control in children between 3 and 14 years old; 2. To dissect the reason why not all children are equally responsive to variations in the social environment.

莱顿个体发展联盟（Leiden Consortium on Individual Development，L-CID）研究由Marinus van IJzendoorn、Eveline Crone、Marian Bakermans-Kranenburg和Rutger Engels于2013年发起。该研究是总括性个体发展联盟（Consortium on Individual Development，CID）的四大工作包之一。L-CID研究是一项大规模纵向干预研究，对500个同性双胞胎家庭进行了为期六年的追踪。L-CID采用队列序贯设计（cohort-sequential design），包含两个队列：幼儿队列（ECC），第一波时年龄为3-4岁；童年中期队列（MCC），第一波时年龄为7-8岁。年度评估包括交替进行的实验室访视或家庭访视，期间收集行为和神经生物学数据。收集的数据除其他用途外，可用于检验哪些儿童特征会影响（受操控的）环境因素的效应。L-CID的目标有二：1. 探究3至14岁儿童社会能力与行为控制的发展；2. 剖析为何并非所有儿童对社会环境变化的反应程度都相同。
