was
given to patients and informants by research associates trained in
its use. Interrater reliability in the assessment of SCID symptoms
was evaluated by having a second research associate observe and
independently rate symptoms during in-person interviews with
42 patients. Reliability was excellent (intraclass r=0.91, 95% confidence
interval [CI]=0.86–0.95) for the number of symptoms
present. Interviewer ratings were monitored throughout the
study by the study psychologist (P.J.R.).
