Lifetime trauma, subjective distress, substance use, and PTSD symptoms in people with severe mental illness: Comparisons among four diagnostic groups

摘要

The current study examines correlations among trauma, high risk behaviors, subjective distress from both trauma and high risk behaviors, and substance use in community mental health clients diagnosed with a severe mental illness, and tests the following key hypothesis: clients with major mood disorders (major depression, bipolar I) will show higher rates of posttraumatic stress disorder (PTSD) symptoms than clients with either schizophrenia or schizoaffective disorder when trauma, high risk behaviors, subjective distress, substance use and gender are controlled. Linear regression demonstrated that only major depression and bipolar disorder varied significantly with PTSD symptoms when controlling for other key factors.
