Developmental trajectories of parents and infants from conception to 3 months postpartum: the singularity of twins
02:00pm to 04:00pm

Twin birth rates have increased worldwide in the last decades. Compared with the well-known health risks associated with twin pregnancy, relatively little is known about the psychological adjustment of couples during the transition to twin parenthood and twins’ early development. In this seminar, the results of several empirical studies conducted as part of her PhD will be presented and discussed.

These studies aimed:

1) to describe the trajectories of parents’ psychological adjustment during the transition to twin parenthood;

2) to determine whether parents of twins and parents of singletons differ on psychological adjustment trajectories;

3) to investigate whether psychological adjustment trajectories vary as a function of mode of conception and parent gender;

4) to examine twins’ fetal development (fetal movements and heart rate) and to investigate factors associated with it.

The methodological choices made will be discussed (e.g., fetal behavior assessed from 2D ultrasound), as well as the potential and challenges of studying twins’ early development.
