at the item severity level prior to conducting interviews independently. Two clinical psychologists (RM, AJ) reviewed all cases at weekly case consensus meetings to minimize potential drift in item severity ratings by interviewers. All symptom severity level and diagnostic decisions were derived by case consensus with the interviewer(s) and both psychologists present. For the purpose of this study, our primary dependent measure of interest was the binary classification of youth based on the presence or absence of an AUD (i.e., abuse or dependence).
