Note.
DSM-III criteria;
DSM-III-R criteria;
DSM-IV criteria.
The Ns at each wave represent the number of complete case data at that one time point. Given the longitudinal nature of the sample, the DSM criteria were revised and added to the assessments as they became available, so the Ns for the final two columns represent all nonmissing data available from for DSM-III criteria (waves 1–7), for DSM-III-R criteria (waves 3–7), and for DSM-IV criteria (waves 6 and 7). Percentages not in parentheses are based upon listwise deletion (N = 363) and percentages in parentheses based upon all nonmissing data available at that wave. Cumulative assessments were based on data at waves 1–7.
