To even better understand human attachment development, longitudinal studies are needed to complement the above-described cross-sectional work. Together with my international collaborators, and in particular Tsachi Ein-Dor, Willem Verbeke, and Michal Mokry, we are moving towards this ambitious goal.
In a first step, we have obtained access to a longitudinal data set called Generation R from The Netherlands, which assessed genetics and epigenetics of over 600 children at birth and followed them up at age 14 months with the Strange Situation Procedure (SSP), with subsequent testing at ages 5-6 and 9-10. We will examine how these measures relate to each other.
In a second step, Tsachi Ein-Dor has obtained private funding to start collecting data from a new cohort of 1500 couples from Israel and to follow them through pregnancy, child birth, and child development. The first set of data will be obtained from December 2018 onward and I can be involved as one of the principal investigators.
Stay tuned for further developments.
