“…For example, outstanding work has been conducted by Dr. Kate Harkness (Queen's University) examining the impact of life stress in depression (e.g., Harkness & Monroe, 2016); the late Dr. John Abela (McGill University) who studied rumination and tested cognitive vulnerability models (e.g., the weakest link hypothesis; Abela & Sarin, 2002) in Canadian and Chinese youth (e.g., Auerbach et al, 2010); Dr. Andrew Ryder (Concordia University) who has investigated how culture shapes the experience and expression of emotional disorders (e.g., Ryder et al, 2012); Dr. David Zuroff (McGill University) who has investigated personality and interpersonal variables associated with depression (e.g., Zuroff et al, 2017); Dr. R. Michael Bagby (University of Toronto) who has explored personality dimensions in depression (e.g., Bagby et al, 2013); Dr. Brett Thombs (McGill University) who has focused on the screening and assessment of depression (e.g., Thombs et al, 2018); Dr. Marlene Moretti (Simon Fraser University) who has contributed to our understanding of sex and gender differences, attachment, and self-regulation in depression (e.g., Moretti & Higgins, 1990); Dr. Margaret Lumley (Guelph University) who has studied the impact of early maltreatment in depression and the importance of positive self-schemas (e.g., Lumley & McArthur, 2016); Dr. Shadi Beshai (University of Regina) who has investigated cognitive behavioral therapy and relapse prevention in depression (e.g., Beshai & Dobson, 2014); Drs. David Dunkley (McGill University) and Simon Sherry (Dalhousie University) who have examined the relations between perfectionism and depression (e.g., Dunkley et al, 2020;Sherry et al, 2013); and countless other university-and hospitalbased psychologists who have made outstanding contributions to research in depression. I hope that the readers of the Canadian Journal of Behavioural Science will enjoy reading the articles in this special issue, that the manuscripts will provide a sense of the breadth and depth of Canadian contributions to the science of depression, and that this issue will inspire the next generation of depression researchers.…”
