During my MPhil in Social and Developmental Psychology at Cambridge I studied the impact of the quality of children’s human and pet relationships on their social and emotional wellbeing. I took this research a step further in my PhD in Psychiatry by examining the extent to which self-harm behaviours among adolescents can be predicted by the security of their attachments to their parents. Self-harm typically originates in adolescence, is addictive, socially contagious, and tends to escalate over time. As such, early interventions are imperative in order to prevent experimentation from becoming habit, incident from becoming epidemic, and harm from becoming suicide. I hope that by uncovering some of the etiological pathways to these deleterious behaviours, my research will lead to the development of more efficacious treatments and better prognoses for patients.
