Jordana Sommer, Dr. El-Gabalawy, Edward Noh, and Kayla Kilborn analyzing data in the HATLab
|
Research Areas
The HATlab has three related primary streams of research.
What is the impact of anxiety and trauma-related disorders on physical health and chronic pain? Understanding the relationships between anxiety and trauma-related disorders (e.g., PTSD), and physical health conditions and chronic pain. These investigations include understanding co-occurrence, mechanisms that explain co-occurrence, and correlates/outcomes of co-occurring conditions (e.g., substance misuse, healthcare utilization, suicide). How does mental health impact adverse health events, and what are common psychological outcomes following such events? Understanding psychological sequelae (e.g., post-traumatic stress disorder, delirium) of adverse health events such as the onset of an acute illness, major surgery and associated complications, and admission to the intensive care unit. Dr. El-Gabalawy is not only interested in negative reactions to such events but also potential positive psychological outcomes such as post-traumatic growth and resiliency, and what pre- and peri-event factors might contribute to particular outcomes. What are feasible interventions to improve health outcomes in adverse health events such as major surgery? Developing targeted interventions aimed at reducing negative psychological outcomes following adverse health events. |
Research Modalities
Dr. El-Gabalawy conducts both primary clinical data driven studies including randomized controlled trials and secondary epidemiological studies using rich data repositories such as Statistics Canada.
