The goal of this study is to develop new methods of administering antidepressant medications that will result in improved drug/placebo separation in randomized controlled trials (RCTs) for Major Depressive Disorder (MDD) and enhanced medication response in open clinical treatment. The highly intensive, weekly visit schedule followed in most antidepressant RCTs radically differs from how antidepressant medications are prescribed in standard clinical practice and is believed to be a major reason why the majority of studies submitted to the Food and Drug Administration (FDA) fail to show a significant difference between medication and placebo. Moreover, a "one size fits all" approach to psychopharmacologic management (i.e., weekly visits for all patients) does not take into account differences between patients that may predispose some individuals to respond positively to frequent follow-up visits, while others may respond negatively or not at all. Clinic visits comprise multiple components that may be therapeutic for depression, including activating patients' behavior, exposing them to medical procedures, permitting social interactions with research staff, and providing supportive meetings with clinicians. Two independent meta-analyses have associated more frequent study visits with increased antidepressant and placebo response as well as decreased separation between medication and placebo. Despite the high costs and potential disadvantages of weekly follow-up visits for patients receiving antidepressant medication, this clinical management strategy has not been studied prospectively to date. It is unknown whether weekly follow-up visits are needed to ensure treatment compliance and patient safety in clinical trials and to what degree contacts with clinicians influence medication and placebo response.
This study utilizes a 2 x 2, double-blind, acute, prospective design randomizing adult outpatients with MDD to "Research Frequency Management" (RFM, weekly study visits) vs. "Community Frequency Management" (CFM, every 4 weeks study visits) and antidepressant medication vs. placebo. Specifying visit frequency as the independent variable in this study has the distinct advantages of being easily operationalized for research purposes avoiding a priori assumptions about which components of study visits influence antidepressant and placebo response (i.e., behavioral activation vs. doctor-patient relationship vs. medical procedures). Close monitoring of all subjects will be assured by telephone evaluations of individuals randomized to CFM at intervals between monthly visits, and additional study contacts will be scheduled as necessary to maintain patient safety (all extra-protocol contacts will be recorded and included as a variable in outcome analyses). Additionally, subjects will be characterized extensively on clinical, demographic, and psychological measures to pilot the study assessment battery and search for predictor variables influencing the effects of contact frequency on medication and placebo response.

Escitalopram is a Selective Serotonin Reuptake Inhibitor (SSRI) medication that appears to help with symptoms of depression by increasing the availability of specific chemicals in the brain.
A placebo (or dummy pill) is an inert (inactive) substance, typically a tablet, capsule or other dose form that does not contain an active drug ingredient.

Change From Baseline Hamilton Rating Scale for Depression 24-Item Scale to Study Completion (8 Weeks)
Scale for depressive symptoms administered by trained rater. The Hamilton is the standard measure of depression severity for clinical trials of antidepressants and was chosen as the primary outcome measure over other depression rating scales to ensure compatibility of study results with our meta-analyses and ongoing studies of expectancy. The scoring is based on the first 24 items of the Hamilton. Sum of the scores of the first 24 items (range from 0 to 74): 0-7 = NORMAL 8-13 = Mild Depression 14-18 = Moderate Depression 19-22 = Severe Depression \>=23 = Very Severe Depression
Time frame: Up to 8 Weeks
Change From Baseline Hamilton Anxiety Rating Scale 14-item Scale
Scale for anxiety symptoms administered by trained rater. The Hamilton Anxiety is a standard measure of anxiety severity in pharmacotherapy studies that has been shown to have acceptable reliability and validity in studies of depressed patients. Each item is scored on a scale of 0 (not present) to 4 (severe), with a total score range of 0-56, where \<17 indicates mild severity, 18-24 mild to moderate severity and 25-30 moderate to severe.
Time frame: Up to 8 Weeks
