Note. N = 241 patients with higher-risk response to acute-phase cognitive therapy were randomized to 8 months of continuation treatment (cognitive therapy, fluoxetine, or pill placebo with clinical management) and followed up to 24 additional months. The Social Adjustment Scale—Self-Report (SAS-SR), Inventory of Interpersonal Problems (IIP), and Dyadic Adjustment Scale (DYS) were predicted by a composite of the Hamilton Rating Scale for Depression, Beck Depression Inventory, and the Inventory for Depressive Symptomatology—Self-report at assessments taken at randomization and every 4 months through 32 months. Multilevel models controlled receipt of non-protocol treatment, continuation phase group, assessment time, and the group × time interaction.
