  1. Prevalence and severity of substance use disorders and onset of psychosis in first-admission psychotic patients.

    Data are from the Suffolk County Mental Health Project, an epidemiological study of first admission psychosis.

    The SCID and instruments measuring symptomatology, personality and background characteristics were administered.

    Respondents were stratified into three groups :

    • (a) no life-time substance diagnosis ;

    • (b) in remission or reporting current mild use at admission ;

    • and (c) current moderate-severe substance abuse at admission.


    Using the SCID severity rating, 17.4% of males and 6.2% of the females had moderate or severe current substance abuse, while 41.5% of males and 68.2% of females had no lifetime substance diagnosis.

    In almost all cases categorized as moderate-severe, the substance diagnosis predated onset of psychosis.

    Females categorized as moderate-severe had an earlier age of onset of psychosis than did females in the other groups.

    There were only slight differences in symptom severity among the groups but more marked antisocial behaviour in the moderate-severe group. (...)
