Fj. Sautter et al., PTSD and comorbid psychotic disorder: Comparison with veterans diagnosed with PTSD or psychotic disorder, J TRAUMA ST, 12(1), 1999, pp. 73-88
Symptoms of posttraumatic stress disorder (PTSD), psychosis, general psycho
pathology, role functioning, violence potential, and cognitive and emotiona
l aspects of psychotic states were compared in three groups of veterans. Gr
oups were defined on the basis of their DSM-IV diagnoses: Psychotic disorde
r and war-related PTSD, war-related PTSD without psychotic symptoms, and ps
ychotic disorder without PTSD. Veterans with PTSD and a comorbid psychotic
disorder showed significantly higher levels of positive symptoms of psychos
is, general psychopathology, paranoia, and violent thoughts, feelings, and
behaviors than the other two groups. These data show that patients with com
orbid PTSD and psychotic disorder show levels of cognitive, emotional, and
behavioral disturbance that far exceed the levels of disturbance seen in pa
tients with PTSD without psychosis or in patients with psychotic disorder.
