Sarah Halligan



Sarah Halligan is Professor of Child and Family Mental Health at the University of Bath. Her research examines the development of psychological disorders, particularly posttraumatic stress disorder (PTSD) and depression, with a focus on children. In the PTSD field, Professor Halligan has studied the cognitive-behavioural, biological and social factors that contribute to disorder following trauma exposure, working with both national and international populations. She is particularly interested to learn how parents and others can support children and adolescents who are struggling with mental health problems, and to identify potential intervention targets.


Children’s posttraumatic distress: understanding the role of socio-contextual factors

Following traumatic experiences (e.g., physical or sexual assault, serious accidental injuries, natural disasters) children are at risk of developing posttraumatic stress disorder and other adverse mental health outcomes. The majority of trauma exposed children rely on informal sources of support for their psychological recovery. This presentation will consider the factors that influence child psychological adjustment following trauma exposure, with a focus on the role that families may play in determining outcomes. In addition to studies of UK children exposed to trauma, research with children growing up in high adversity international settings will be presented.
