Using the Perfectionism Social Disconnection Model to Predict Disordered Eating Behaviours in an Undergraduate Sample

Physical distancing regulations implemented to limit the spread of the novel coronavirus during the COVID-19 pandemic have increased feelings of social isolation globally. Unfortunately, this presents another public health concern as social isolation has been linked to depression, anxiety, and eating disorders. Previous research has shown that people with perfectionistic personality types are more likely to experience adverse mental health outcomes in response to social isolation. This is concerning when considering that, similar to social isolation, perfectionism increases individuals' risk of developing depression, anxiety, and eating disorders. The Perfectionism Social Disconnection Model (PSDM; Hewitt et al., 2006) can be used to understand the relationship between perfectionism, social isolation, and adverse mental health outcomes. The PSDM states that perfectionism creates social disconnection, which increases the risk of experiencing mental health concerns. To the best of my knowledge, this model has not yet been applied to the understanding of eating disorders in adults. This is an important population to study as eating disorders have devastating effects both at the individual level and for society. Further, perfectionism has been found to maintain these disorders. The goal of my Master's research will be to apply the PSDM to a sample of undergraduate students to determine if this model can be used to predict disordered eating behaviours. Understanding this relationship has powerful implications for the prevention and treatment of eating disorders in adults. By addressing underlying contributing factors i.e. perfectionism and social disconnection rather than the specific symptoms, we can uncover treatment targets that can be used to prevent multiple disorders.
