BACKGROUND: A lack of an aetiologically based nosology classification has contributed to instability in psychiatric diagnoses over time. This study aimed to examine the diagnostic stability of @entity716 diagnoses using data from an incidence sample of @entity716 cases, followed up after 10 years and to examine those baseline variables which were associated with diagnostic change. METHOD: Data were examined from the   SOP and   SOP-10 studies, an incidence and follow-up study, respectively, of a population-based cohort of first-episode @entity716 cases from two sites. Diagnosis was assigned using @entity1479 -10 and DSM-IV-TR. Diagnostic change was examined using prospective and retrospective consistency. Baseline variables associated with change were examined using logistic regression and likelihood ratio tests. RESULTS: Slightly more (59.6%) cases had the same baseline and lifetime @entity1479 -10 diagnosis compared with DSM-IV-TR (55.3%), but prospective and retrospective consistency was similar. @entity161 , @entity162 and drug-induced @entity716 were more prospectively consistent than other diagnoses. A substantial number of cases with other diagnoses at baseline ( @entity1479 -10, n = 61; DSM-IV-TR, n = 76) were classified as having @entity161 at 10 years. Many variables were associated with change to @entity161 but few with overall change in diagnosis. CONCLUSIONS: Diagnoses other than @entity161 should to be regarded as potentially provisional.
