Posthospital course and outcome in schizophrenia.
To study the early course of schizophrenia, we assessed 79 early phase, young, DSM-III schizophrenic patients at two successive posthospital follow-ups, 2.5 and 5.0 years after index hospitalization. More than 50% of the sample had poor overall outcome, with either severe impairment in functioning and symptoms, or suicide, in the follow-up period. Rehospitalization rates decreased significantly during the course of the two posthospital assessments, despite the sample showing persisting psychosis. Only a small group of schizophrenic patients showed complete remission: 10% at the first follow-up and 17% at the second follow-up, when patients who suicided are excluded from consideration. While progressive deterioration is not common in schizophrenia, our relatively negative findings challenge the conclusions of some other longitudinal studies. Implications of our data on schizophrenic course are discussed.

Early longitudinal course of acute-chronic and paranoid--undifferentiated schizophrenia subtypes and schizophreniform disorder.
This prospective longitudinal study examined symptoms and adjustment at 2 and 4 years posthospital discharge in Research Diagnostic Criteria (RDC) and Diagnostic and Statistical Manual (DSM-III) schizophrenia subtypes and in DSM-III schizophreniform disorder. Delusions, hallucinations, thought disorder, anxiety, depression, and specific areas of community adjustment were assessed at each follow-up. RDC acute and subacute schizophrenia and DSM-III schizophreniform disorder were associated with more satisfactory overall adjustment and lower frequencies of psychotic symptoms over time. No significant differences in the course of symptoms or adjustment were found between paranoid and undifferentiated schizophrenia subtypes. Schizophrenia subtyping schemes based on length of illness features appear more prognostically viable than do symptom-based approaches.

Risk for suicide in schizophrenia and other psychotic and nonpsychotic disorders.
To determine the rate of suicide in young, early phase schizophrenics and other psychotic disorders, and to analyze risk factors for suicide, a large sample of patients was prospectively assessed at index hospitalization and then followed up systematically after discharge. Thirty-six patients committed suicide and these patients were compared with those who did not commit suicide for major diagnostic and prognostic factors. Results indicated the following: a) During early years, schizophrenics and other types of psychotic patients were more likely to commit suicide than nonpsychotic patients. b) Similarly, among depressives, psychotic depressed patients were more likely to commit suicide than nonpsychotic depressed patients. c) Schizophrenics and other psychotic patients were especially vulnerable to suicide within the first 6 years of their first hospitalization. d) Among the combined sample of psychotic patients (schizophrenic and other psychotic patients), those at greater risk for suicide were unmarried, white, high IQ, male patients with a more gradual onset of disorder and were of "chronic" Research Diagnostic Criteria subtypes.

Prognostic significance of cerebral status: dimensions of clinical outcome.
This report examines the relationship between a set of neurobehavioral predictor variables (premorbid cognitive-perceptual abilities, sensorimotor functions, and complex integrative skills) and three dimensions of clinical outcome (social outcome, work functioning, and rehospitalization) 2 years after discharge from inpatient treatment for a group of psychiatric disorders. Results indicated the strongest relationship was between premorbid ability levels and work performance, particularly maintaining stability of employment or work role function. This finding is discussed from the standpoint of neurological processes underlying early acquisition of basic cognitive-perceptual skills in the prediction of outcome.

Outcome of schizoaffective disorder at two long-term follow-ups: comparisons with outcome of schizophrenia and affective disorders.
OBJECTIVE: This research assessed whether the outcome of schizoaffective disorder is more similar to that of schizophrenia or that of affective disorders. METHOD: The authors conducted a prospective follow-up study of 101 schizoaffective, schizophrenic, bipolar manic, and depressed patients assessed at three times: during hospitalization and 2 and 4-5 years later. The follow-up test battery involved detailed assessment of social functioning, work performance, symptoms, posthospital treatment, and rehospitalization. RESULTS: Outcome for schizoaffective patients 4-5 years after hospitalization differed significantly from that for patients with unipolar depression. However, the differences between schizoaffective and bipolar manic patients were more equivocal. Unlike the patients with bipolar disorder, only a limited number of patients with schizoaffective disorder showed complete recovery in all areas throughout the year preceding the 2-year follow-up and the year preceding the 4- to 5-year follow-up. The differences in outcome between schizoaffective and schizophrenic patients were also mixed. These two groups showed some similarities in outcome, but there were fewer schizoaffective than schizophrenic patients with uniformly poor outcome in all areas. CONCLUSIONS: Overall, schizoaffective patients showed some similarities to both schizophrenic and bipolar manic patients. Schizoaffective patients had somewhat better overall posthospital functioning than patients with schizophrenia, somewhat poorer functioning than bipolar manic patients, and significantly poorer functioning than patients with unipolar depression. The data suggest that when mood-incongruent, schizophrenic-like psychotic symptoms are present in the acute phase, they predict considerable difficulty in outcome, even when affective syndromes are also present, as in schizoaffective disorder. It is likely that schizoaffective disorder is not just a simple variety of affective disorder.

European versus U.S. data on the course of schizophrenia.
OBJECTIVE: The present research attempts to add to the existing body of data on the course of schizophrenia by comparing the findings of a prospective study of a group of U.S. schizophrenic patients with data from two European studies. METHOD: Seventy-four U.S. patients given the diagnosis of schizophrenia according to Research Diagnostic Criteria were longitudinally assessed at hospitalization and at three intervals up to 10 years after illness onset. The longitudinal criteria for type of onset, course of illness, and outcome were derived from the European studies of Manfred Bleuler and Luc Ciompi. The type of onset, course of illness, and outcome of the U.S. patients were compared with those of the patients in the two European studies. RESULTS: A lower rate of acute onset and of episodic illness was found in the U.S. patients, but the relative frequency of a number of major overall course patterns was similar across studies. CONCLUSIONS: Despite many potential threats to comparability, the results of the European and U.S. longitudinal studies of the course of schizophrenia were fairly congruent in terms of the relative rate with which patients fell into the categories established by Bleuler and Ciompi. These results are encouraging in that they point to the possibility of estimating the rate of occurrence of particular expressions of the overall course of schizophrenia.

Outcome in manic disorders. A naturalistic follow-up study.
To study outcome in manic patients treated under routine clinical conditions, 73 manic and 66 unipolar depressed patients were followed up 1.7 years after hospitalization. A surprisingly large percentage of manic patients showed difficulty in post-hospital adjustment, and over 40% experienced a manic syndrome during the follow-up period. Manic patients showed poorer outcomes than did unipolar depressives. Manic patients taking lithium carbonate did not show better outcome than those not taking lithium carbonate. The results suggest (1) many hospitalized manic patients have a severe, recurrent, and pernicious disorder; and (2) in routine clinical practice, lithium carbonate treatment is an effective prophylaxis for fewer than the 70% to 80% of manic patients previously reported.

Rapid cycling in unipolar and bipolar affective disorders.
To characterize the nature of rapid cycling affective disorders, the authors analyzed mood fluctuation patterns in 570 patients with affective disorders hospitalized in 1960, 1975, or 1985. Patients' records were rated for the frequency, duration, and complexity of distinct affective states. Very rapid mood fluctuations were absent among bipolar patients in 1960 but were evident in 1975 and 1985. In each year, bipolar patients displayed more frequent, complex, and mixed episodes than did unipolar patients. The results suggest that more frequent episodes occur among bipolar than unipolar patients and that very rapid switch processes have become more widespread for some bipolar patients.

Impaired perspective and thought pathology in schizophrenic and psychotic disorders.
Impaired perspective was studied in schizophrenic and thought-disordered patients to analyze hypotheses about its role in thought disorder. Eighty-three schizophrenic patients, other psychotic patients, and nonpsychotic patients judged the adequacy of their own and others' verbalizations under several different conditions. Thought-disordered patients had significantly more impaired perspective than nonthought-disordered patients (p less than 0.05). Patients had significantly poorer perspective about their own verbalizations than about those of other patients (p less than 0.01). Schizophrenic and other psychotic patients showed poor perspective about their own verbalizations. Thought-disordered patients did not view their bizarre verbalizations as stranger than their nonbizarre verbalizations. Impaired perspective and bizarre responses were more frequent under certain conditions. When focusing on the adequacy of their response, patients were significantly less idiosyncratic. The results support the hypothesis that impaired perspective plays a role in thought disorder. A more comprehensive model of thought disorder and disorganization, which includes impaired perspective, is discussed.

Cyclothymic mood swings in the course of affective disorders and schizophrenia.
The authors assessed cyclothymic mood swings and psychosocial adjustment in 38 unipolar depressed, 27 bipolar, 35 schizophrenic, and 27 other psychiatric patients 4 years after hospital discharge and in 153 normal control subjects. The patients were significantly more cyclothymic at follow-up than the control subjects, but there were no differences in cyclothymia between the diagnostic groups. Cyclothymic patients showed significantly poorer posthospital functioning than noncyclothymic patients. These findings raise questions concerning the scope of the hypothesized cyclothymic-bipolar spectrum. Minor mood swings in a variety of patients with poor posthospital adjustment may reflect persistent vulnerability to psychopathology.

Schizophrenic thought disorder at follow-up. A persistent or episodic course?
This follow-up investigation examined the course of thought disorder in early, young schizophrenic, other psychotic, and nonpsychotic patients. Patients were assessed for the severity of thought disorder at index hospitalization and at two and four years after hospital discharge. Follow-up evaluations included assessments of adjustment and short-term outcome. Schizophrenic patients showed more thought disorder than nonschizophrenic patients at all three periods. Almost 40% (16/41) of the schizophrenic patients exhibited persistent thought disorder symptoms after the acute phase and an additional 37% (15/41) showed an episodic thought disorder course. Across diagnoses, patients who were thought disordered at both follow-ups demonstrated higher rates of unemployment and rehospitalization than did patients in non-thought-disordered and episodic thought disorder groups. To date, 25% (16/65) of psychotic nonschizophrenic patients showed persistent thought disorder courses similar to schizophrenia, while another 40% (24/65) showed remitting thought disorder symptoms more common to nonpsychotic patients.

Process-reactive dimension and outcome for narrow concepts of schizophrenia.
The data presented by the authors suggest a more successful prediction of outcome by the process-reactive dimension when it is applied to schizophrenic patients defined according to broad concepts of schizophrenia (e.g., DSM-II) than to narrow concepts of schizophrenia (e.g., DSM-III). Research indicates that the DSM-III is more likely than the DSM-II diagnosis to be composed of "poor prognosis" schizophrenia, as defined by the classical prognostic indicators. In general, the overall results could support the views of Herron and others that the process-reactive dimension is more valuable as a predictor for a schizophrenia spectrum than for modern, narrow concepts of schizophrenia. However, while recent data of the authors indicate that DSM-III schizophrenic patients show poorer outcome than DSM-II schizophrenic patients, they also indicate that (1) DSM-III schizophrenic patients still show heterogeneity in prehospital functioning and outcome, and (2) other prognostic indexes, such as the Zigler-Phillips Scale and the Vaillant-Stephens Scale, have some efficacy in predicting course and outcome among DSM-III schizophrenic patients. Data on prehospital functioning and outcome are discussed in terms of two contrasting models--a developmental model and a natural history model of the course of schizophrenia.

The prognostic relevance of delusions in depression: a follow-up study.
To determine whether delusional depression has a different clinical course from other types of depression, the authors followed up 31 unipolar delusional depressed patients, 28 unipolar nonpsychotic depressed patients, and 51 schizophrenic patients 14 months after hospital discharge. Patients were assessed on 1) overall outcome, 2) psychotic, anxiety-neurotic, and depressive symptoms, 3) social and work functioning, and 4) rehospitalization. The delusional depressed patients showed significantly more mood-incongruent delusions at follow-up. Surprisingly, the nonpsychotic depressed patients exhibited more depressed mood and significantly more anxiety at follow-up. The findings suggest that the diagnostic distinction between delusional and nonpsychotic depression is relevant to the clinical course of major depression.

A longitudinal study of thought disorder in manic patients.
To study the persistence of thought disorder in manic patients, 34 manic patients were compared with 30 schizophrenic and 30 nonpsychotic patients on four indexes of thought pathology at two phases of disorder: during the acute inpatient phase and one year after hospitalization. Patients were also compared with a control sample of 34 normal subjects. The data indicated that during the acute in hospital phase, both manic and schizophrenic patients were severely thought disordered; at follow-up, a subsample of manic patients showed severe thought disorder; despite the severe thought disorder found at follow-up in some manic and schizophrenic patients, both groups showed a significant reduction of thought pathology at follow-up; and there was a trend for a larger reduction of thought disorder in manic than in schizophrenic patients. The difference, however, was not significant when initial levels of severity were controlled.

Predictors of outcome in schizophrenia: the process-reactive dimension.
Premorbid social-sexual competence and the process-reactive dimension, as assessed by the Phillips Scale, were investigated as predictors of posthospital adjustment in a prospective study of two samples of 141 young, early phase schizophrenics (a private hospital sample and a state hospital sample). The Phillips Scale predicted subsequent outcome at significant levels for one of the two samples of DSM-II schizophrenics (a "broad" construct of schizophrenia). It did not predict outcome as well for DSM-III schizophrenics (a "narrow" construct of schizophrenia). Mixed results emerged from separate analyses of first-admission schizophrenics only and for male schizophrenics only. The data indicated that marital status accounts for some of the positive relationship between the Phillips Scale and later outcome. A more focused measure of prehospital social adjustment successfully predicted social functioning at followup for both DSM-II and DSM-III schizophrenics (p less than .05). There were some significant and near-significant relationships, but overall results suggest that when the influence of chronicity and marital status is reduced, the relationship between the Phillips Scale and subsequent outcome is less robust than was once thought.

The early course of schizophrenic thought disorder.
The current investigation studied the early course of positive thought disorder and its relationship to other aspects of schizophrenic outcome. Forty-eight schizophrenics diagnosed using the Research Diagnostic Criteria (RDC), 51 psychotic nonschizophrenics, and 67 nonpsychotic patients were studied at index hospitalization and at a 1.5-year followup. Most thought-disordered schizophrenics and other psychotic patients showed some reduction in thought pathology between index hospitalization and followup (p less than .02). A larger percentage of schizophrenics than other psychotic and nonpsychotic showed thought disorder at the acute phase and at followup assessment (p less than .05), although only a subgroup of 27 percent of the schizophrenics showed severe thought disorder at followup. At followup, severely thought-disordered schizophrenics showed residual signs of psychosis and poor functioning in other areas. Positive thought disorder in schizophrenics at followup most often occurred within the context of an unremitted illness and was less frequently due to a new, acute episode of disturbance. Continuously thought-disordered schizophrenics exhibited more severe impairments in life adjustment at 1.5-year followup than did episodic or nonthought-disordered schizophrenics (p less than .02). The results suggest that severe thought disorder is a persistent characteristic in a subgroup of early schizophrenics.
