There is evidence that premorbid adjustment can differentiate schizophrenia from schizoaffective disorder. We recruited 41 patients with schizophrenia and 24 patients with schizoaffective disorder without substance abuse 6 months before the assessment. Diagnoses were based on the Structured Clinical Interview for DSM-IV. Psychotic symptoms were rated with the Positive and Negative Syndrome Scale, the Calgary Depression Scale was used to assess depressive symptoms, and the Global Assessment of Functioning Scale was used to rate global psychosocial functioning. Premorbid adjustment was evaluated with the Premorbid Adjustment Scale. Patients with schizophrenia showed worse premorbid adjustment compared with the patients with schizoaffective disorder. The areas of “peer relationships” and “scholastic performance” showed deficits in schizophrenia. Significant associations were found between premorbid adjustment life periods and symptom severity in both groups. Differences found between groups may be related to an earlier illness onset in the schizophrenic group. Premorbid adjustment may be a useful clinical feature to differentiate schizoaffective disorder from schizophrenia.
