Christchurch five-year-olds will be part of a three-year study to see they settle into primary school in the post-earthquake era.
University of Canterbury researcher Annabel Carter from the School of Health Sciences has looked at children who had lived through earthquakes and has found that up to 78 per cent of youngsters may experience some psychological symptoms for many years following even a single traumatic event.
A wide range of issues has been identified in the research including loss of interest in playing, becoming clingy, increasing irritability, problems with concentration and sleep problems.
Ms Carter has researched studies of children post-earthquakes in Northridge, California (1994), Kobe, Japan (1995), Athens (1999), Wenchuan, China (2008) and in other natural disasters.
This study, for Ms Carter's Masters thesis in health sciences, would look at the children's' understanding of helping, caring and learning.
