The task: Critical Literature Review. Perform a critical literature review discussing biological, psychological and social factors that are most strongly linked to the aetiology and/or maintenance of the disorder in your chosen film (either Posttraumatic Stress Disorder or Cocaine Use Disorder). In so doing, you should clearly evidence whether an integrative approach is superior to unidimensional models (e.g., better than models with only biomedical, psychological, or social causes).
