Stability of DSM-III-R Diagnoses: Study of a Case Register

Abstract

We studied the diagnostic stability and the factors associated with it in 1,443 psychiatric patients with multiple admissions for a period of 45 months. We successively considered the whole population, the psychotic and then the schizophrenic patients. Demographic and DSM-III-R diagnostic information was collected on a computerized database. During the observation period, 1,443 patients were hospitalized twice or more. Diagnostic stability ranged from 34 to 86%. Psychotic disorder was the most stable, whereas adjustment and anxiety disorders were the least stable. Among schizophrenic patients, higher stability appeared for residual and disorganized types (83 and 71%, respectively). Statistical analysis did not show any variable associated with change, apart from the diagnoses themselves. The reasons that could explain changes are discussed, as well as the clinical consequences of these shifts.

First-Episode Psychosis: Diagnostic Stability over One and Two Years

“…Our findings concerning schizophrenia and its stability are in accord with those of Tsuang et al [2] , MunkJorgensen [5] , Schwartz et al [1] , Huguelet et al [4] and Schimmelmann et al [16] . Our findings of the infrequent stability of schizophreniform disorder match those of Naz et al [14] and Veen et al [15] , but not Schimmelmann et al [16] .…”

“…The stability of clinical diagnoses in psychosis has been evaluated in readmission populations [2][3][4] or in register-based populations [5,6] . As this issue has been reviewed in detail by several others [7] , only a condensation of findings will be presented.…”

Test–retest reliability of schizoaffective disorder compared with schizophrenia, bipolar disorder, and unipolar depression—a systematic review and meta‐analysis

“…Out of 4,415 articles screened and 327 articles evaluated at full‐text level, we included 49 articles on 48 studies (Fig. ).…”

Diagnostic shift in patients diagnosed with schizoaffective disorder: a systematic review and meta‐analysis of rediagnosis studies

“…We screened 4,415 articles, evaluated 327 articles at full‐text level, and included 31 studies in our quantitative analysis: 27 on the shift from SAD and 23 on the shift to SAD (Fig. ).…”
