There is a high prevalence of traumatic events within individuals diagnosed with schizophrenia, and of auditory hallucinations within individuals diagnosed with posttraumatic stress disorder (PTSD). However, the relationship between the symptoms associated with these disorders remains poorly understood. We conducted a multidimensional assessment of auditory hallucinations within a sample diagnosed with schizophrenia and substance abuse, both with and without co-morbid PTSD. Results suggest a rate of co-morbid PTSD similar to those reported within other studies. Patients who suffered co-morbid PTSD reported more distressing auditory hallucinations. However, the hallucinations were not more frequent or of longer duration. The need for a multidimensional assessment is supported. Results are discussed within current theoretical accounts of traumatic psychosis.
