Research Interests

Lauren conducted psychosocial research on eating pathology across the weight spectrum. Her research interests broadly include the investigation of psychosocial factors, such as readiness for change, that predict positive outcomes for bariatric surgery patients, as well as the effectiveness of psychological interventions designed to improve outcomes for this patient population. Her Master’s thesis investigated the efficacy of Motivational Interviewing (MI) for improving motivation and self-efficacy for change for bariatric patients experiencing difficulties adhering to the post-operative dietary guidelines. In her doctoral work, she is investigating the efficacy of various strategies, including self-compassion, for improving significant body image disturbances in individuals with obesity or overweight. Additional projects include the impact of stigmatizing visual portrayals of obesity on attitudes towards bariatric surgery and mindfulness-based treatment approaches for eating disorders.

Clinical Interests

Lauren has worked as a study therapist in numerous research settings, including a trial examining the efficacy of telephone-based cognitive behavioural therapy (CBT) for bariatric surgery patients and a trial examining the comparative efficacy of CBT versus MI for facilitating rapid treatment response in patients with bulimia nervosa. She has worked as a clinical assessor on a trial investigating the concurrent treatment of Posttraumatic Stress Disorder and Eating Disorders. She also conducted MI with post-operative bariatric surgery patients for her Master’s thesis, and provided skills training in self-compassion and cognitive restructuring for her dissertation. Lauren completed her final clinical practicum placement at Humber River Regional Hospital Adult Mental Health Program, where she provided empirically driven assessment and treatment for individuals with a range of clinical presentations, including psychosis, personality disorders, and complex mood and anxiety diagnoses. She has also completed practica placements at St. Michael’s Hospital Department of Family and Community Medicine (Clinical Psychology Training Clinic) and at the Eating Disorder Day Hospital at Toronto General Hospital. Lauren’s primary theoretical orientation is cognitive behavioural; however, she values integrating other evidence-based approaches, such as mindfulness- and acceptance-based therapies, when they lend themselves to the case formulation.  Lauren completed her postdoctoral internship at St. Joseph’s Healthcare, and is currently completing a postdoctoral fellowship there.
