Objectives To determine the relationship between diagnosis and cognitive functioning in a first‐episode sample. Methods 175 subjects were diagnosed (SCID) on admission to a comprehensive treatment programme for early psychosis and 1 year later. Symptoms (PANSS), social functioning and cognitive functioning (using a comprehensive cognitive battery) were assessed initially and at 1 year. Subjects were divided into three groups: (1) Stable diagnosis of schizophrenia over 1 year ( n =84). (2) Initial diagnosis of schizophreniform, brief psychotic disorder, substance induced psychosis or psychosis NOS but who met criteria for schizophrenia at 1 year ( n =49) and (3) Stable diagnosis over 1 year of schizophreniform, brief psychotic disorder, substance induced psychosis or psychosis NOS ( n =44). Results There were significant differences amongst the three groups at both assessment periods in positive and negative symptoms and social functioning. There were no differences amongst the groups in cognitive functioning. Conclusions Individuals with psychotic disorders who do not go on to develop schizophrenia do not differ significantly in neurocognition from those who do develop schizophrenia, although they may have advantages in other areas.
