Current Research

We are currently working on two programs of research.  After having succesfully executed the largest study to date of early infant-caregiver interactions within the vaccination context (original n= 760; The OUCH Cohort), we have moved on to understand mechanisms involved with the development of pain and non-pain related distress regulation during the 2nd year of life with a new cohort (The Cardio OUCH cohort).  Using infrastructure from the Canada Foundation of Innovation and awards to the OUCH Team from all three Canadian tri-council funding bodies, we will be running studies that not only focus on behaviour but also cardiac physiology outcomes.  The other important program of research seeks out to mobilize data from the original cohort study to teach health care professionals about ways to support infant mental health principles relating to the caregiver-child relationsip within the vaccination appointment.
