Dr Jessica Armitage
Research Associate, Division of Psychological Medicine and Clinical Neurosciences
Overview
I am a Research Associate based at the Wolfson Centre for Young People's Mental Health. My research focuses on population changes in child and adolescent mental health. I am particularly interested in time trends and in understanding the factors that may have contributed to recent increases in depression and anxiety. I am also interested in resilience and predictors of positive mental health and wellbeing, and have previously conducted research on resilience following peer victimisation.
