  1. Lifetime prevalence, demographic risk factors, and diagnostic validity of nonaffective psychosis as assessed in a US community sample : The national comorbidity survey.

    Article - En anglais


    We seek to estimate lifetime prevalence and demographic correlates of nonaffective psychosis in the US population assessed by a computer-analyzed structured interview and a senior clinician.


    In the National Comorbidity Survey, a probability subsample of 5877 respondents were administered a screen for psychotic symptoms.

    Based on the response to this screening, detailed follow-up interviews were conducted by mental health professionals (n=454).

    The initial screen and clinical reinterview were reviewed by a senior clinician.

    Results are presented for narrowly (schizophrenia or schizophreniform disorder) and broadly (all nonaffective psychoses) defined psychotic illness.


    One or more psychosis screening questions were endorsed by 28.4% of individuals.

    By computer algorithm, lifetime prevalences of narrowly and broadly defined psychotic illness were 1.3% and 2.2%, respectively.

    Of those assigned a narrow diagnosis by the computer, the senior clinician assigned narrow and broad diagnoses to 10% and 37%, respectively.

    By clinician diagnosis, lifetime prevalence rates of narrowly and broadly defined psychosis were 0.2% and 0.7%, respectively.

    A clinician diagnosis of nonaffective psychosis was significantly associated with low income ; unemployment ; a marital status of single, divorced, or separated ; and urban residence. (...)
