RATIONALE: According to the <i>Diagnostic and Statistical Manual of Mental Disorders,</i> 4th edition, schizoaffective disorder refers to schizophrenia with elements of a mood disorder, either mania or depression. The prognosis is generally better for schizoaffective disorder than for the other types of schizophrenia, but it's worse than the prognosis for a mood disorder alone. Option 1 is incorrect because personality disorders and psychotic illness aren't listed together on the same axis. Option 3 is incorrect because schizophrenia is a major thought disorder, and the question asks for elements of another disorder. Clients with schizoaffective disorder aren't suffering from schizophrenia and an amnestic disorder.NURSING PROCESS STEP: AssessmentCLIENT NEEDS CATEGORY: Psychosocial integrityCLIENT NEEDS SUBCATEGORY: NoneCOGNITIVE LEVEL: Comprehension
