Note. N = 241 patients who had higher-risk response to acute-phase cognitive therapy and were randomized to 8 months of continuation treatment (cognitive therapy, fluoxetine, or placebo) and followed up to 24 additional months. For the Social Adjustment Scale—Self-Report (SAS-SR), Inventory of Interpersonal Problems (IIP), and Dyadic Adjustment Scale (DYS), 10 assessments occurred at intake to acute-phase cognitive therapy and approximately every 4 months thereafter. For the Range of Impaired Functioning Tool (RIFT), functioning estimates were computed at acute-phase intake, randomization, and for each month 1–32 after randomization. Tabled results are from repeated-measures multilevel models. Multilevel models controlled receipt of non-protocol treatment.
