Total n for these analyses = 791. Simultaneous Multiple Multinomial Associations are adjusted for the percentage of parents who were directly interviewed and all of the variables in the column. Values in the table are odds-ratios (95% confidence intervals). Parental history of disorder is computed as the percentage of parents with each disorder. Analyses including family history variables are adjusted for the percentage of parents who received diagnostic interviews. To increase the consistency between the unconditional and conditional solutions, constraints were placed on the threshold and slope parameters for anxiety disorders in the class reflecting a consistently very low probability of having an anxiety disorder. Class 1 is the persistent depression class; Class 2 is the persistent anxiety class; Class 3 is the later onset, with increasing depression class; Class 4 is the increasing depression class; Class 5 is the initially high, but decreasing anxiety class; and Class 6 is the consistently low depression and anxiety class.
