Research Interests

Bethany is broadly interested in the eating disorder, weight, and body-image related field. Her research thus far has focused on factors related to negative body image and means by which we can improve individuals’ perceptions of their own bodies. In her Master’s work, this included examining the role of weight bias internalization in a self-compassion intervention for body image for those with excess weight.

Clinical Interests

Bethany is interested in the use of Cognitive-Behavioural Therapy (CBT) and Mindfulness-Based Cognitive Therapy (MBCT) in treating psychological disorders. She has completed a practicum at St. Michael’s Family Health Team where she developed skills in administering CBT for mood, anxiety, obsessive-compulsive, and trauma-related disorders. She is currently completing a practicum at Sunnybrook’s Frederick W. Thompson Anxiety Disorders Centre where she provides CBT and MBCT for individuals with Obsessive Compulsive Disorder. She is also working as a therapist for a randomized controlled trial in the HEAL lab, providing virtual CBT for post-operative bariatric patients.
