Psychological trauma, stress, childhood abuse, neglect, and loss are mentioned as important features or risk factors for mental disorders in 15 out of 19 sections of the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM-5]). This means that, according to the DSM-5, trauma and stress are relevant themes throughout the mental health field, not solely an area of subspecialty. Despite the recognition of the widespread role of trauma and stress in the DSM-5, there are inconsistencies in the discussion of trauma, including its relationship to anger and aggression, that should be corrected in future editions of the manual.
