Was at least 1 record obtained from a hospital, clinic or clinician about the subject's psychiatric history?

Was there evidence of a history of psychotic illness in relatives? (0=No evidence of family history of a psychotic illness (MGS2 cases, complete assessment of family not made); 1=Suspected history of psychotic disorder in a first- or second-degree relative (MGS2, see protocol description); 2=Definite history of psychotic disorder in a sibling, half sibling or parent (MGS1, all diagnoses in relatives were based on full in-person assessment and consensus diagnosis)

The total of items 'cs_A1' (variable) through A5 - note that bizarre delusions (A1a) and voices commenting or conversing (A2a) count as an extra "point", so that a sum of 2 indicates that Criterion A has been med (e.g., for bizarre delusions, one would get 1 for A1 and 1 for A1a, totaling 2).
