Study Arms:
- CBT/Escitalopram (Type: EXPERIMENTAL): 12 weeks open-label escitalopram (10-20mg/day as tolerated), followed by 16 weeks individual cognitive behavioral therapy plus continuation escitalopram at same dose as end of first 12 weeks, followed by 28 weeks maintenance escitalopram at same dose as at end of first 12 weeks. Up to 3 booster sessions of CBT allowed during the 28 week maintenance phase. CBT consists of 16 sessions of relaxation training, cognitive restructuring, and problem-solving skills training.
- No CBT/escitalopram (Type: ACTIVE_COMPARATOR): 12 weeks open-label escitalopram (10-20 mg/day as tolerated), followed by 16 weeks continuation escitalopram at same dose as at end of first 12 weeks, followed by 28 weeks maintenance escitalopram at same dose as at end of first 12 weeks.
- CBT/placebo (Type: PLACEBO_COMPARATOR): 12 weeks open-label escitalopram (10-20mg/day as tolerated), followed by 16 weeks individual cognitive behavioral therapy plus continuation escitalopram at same dose as end of first 12 weeks, followed by 28 weeks of pill placebo. 28 weeks of pill placebo includes a taper period of a duration dependent on the initial dose of escitalopram, but in all cases taper to placebo is complete after 8 weeks. Up to 3 booster sessions of CBT allowed during the 28 week maintenance phase. CBT consists of 16 sessions of relaxation training, cognitive restructuring, and problem-solving skills training.
