Outcome Measures
Primary Outcomes (3)
Response as Assessed by Participants' Change in Depression Rating
Comparison of treatment arms (Medication + ICI, Placebo+ICI, and ICI only). The Hamilton Depression Rating Scale (HAM-D-17) used here is a 17-item scale that measures severity of depression. Items are individually scored from 0-4 or from 0-2 depending on the item, and the individual scores for each item are added to comprise one score. Higher scores indicate greater severity of depression. Possible scores on the scale range from a minimum of zero (0) to a maximum of 52.Response is defined as a 50% decrease in HAMD-17 scoring. Remission defined as a HAMD-17 score of 7 or less.
Baseline, Week 8
Average Change in 3 Weeks of Participant Treatment Expectations
Patient Attitudes and Expectations Form used for assessing expectation. The California Pharmacotherapy Alliance Scale, a measure associated with outcomes of antidepressant pharmacotherapy, used to measure participants' perceptions of: (a) participants' commitment to treatment; (b) participants' working capacity; (c) treatment providers' understanding and involvement; and (d) goal and working strategy consensus between participant and treatment provider. This is a 24-item questionnaire with a 7-point Likert scale (1 = not at all, 7 = very much so). Total score ranges from a minimum of 0 and a maximum of 120. The score is determined by a combination of negative and positive items. To assure negative items are reflected, subtract each of the negative item ratings from 8; for example, a rating of 1 becomes 7 (8 minus 1). The scores are computed by summing the items and dividing the total by 6 to procure the mean rating. A lower score indicates a worse outcome.
Averaged over 3 time points (Baseline, randomization, and end of lead-in)
Change in Hamilton Depression Assessment Score
Comparison of treatment arms (Medication + ICI, Placebo+ICI, and ICI only). The Hamilton Depression Rating Scale used here is a 17-item scale that measures severity of depression. Items are individually scored from 0-4 or from 0-2 depending on the item, and the individual scores for each item are added to comprise one score. Higher scores indicate greater severity of depression/worse outcome. Possible scores on the scale range from a minimum of zero (0) to a maximum of 52.

Study Arms (3)
MED
ACTIVE COMPARATORFor medication treatment, three different types were utilized and assigned specifically to each subject depending on their condition: MED 1: Venlafaxine XR. MED 2: Duloxetine (Cymbalta) MED 3: Escitalopram (Lexapro)
Placebo (PBO)
PLACEBO COMPARATORSubjects enrolled will receive interpersonal clinical interaction (ICI) along with a placebo treatment (Interaction and assessment as in ICI plus double blinded treatment with placebo tablets).
Interpersonal Clinical Interaction (ICI)
OTHERSubjects assigned to the interpersonal clinical interaction (ICI) will undergo a one-week waiting period after the initial assessment. Visits will involve a session with a research nurse that will be approximately 20 minutes in length; visits at baseline, end of lead-in, and 1, 2, 4, and 8 weeks also will include a brief (5-10 minutes) meeting with a physician.
Interventions
Subjects assigned to the placebo (PBO) or medication (MED) condition will enter double-blind treatment with either venlafaxine XR, duloxetine, escitalopram, or placebo after lead-in. They will undergo the same schedule, structure, and intensity of visits as in the ICI condition, but also will be randomized to receive treatment with a pill. Subjects randomized to medication will be started on one tablet each morning of either venlafaxine XR 75 mg., duloxetine 30 mg., or escitalopram 10 mg. Dosages will be increased in a double-blinded manner by increasing the number of pills administered by one pill every three to five days until the final dose is achieved (225 mg., 90 mg., and 30 mg. respectively for venlafaxine XR, duloxetine, and escitalopram). In order to maintain blinding during dosage increase, the number of tablets of placebo will be increased every three to five days as well.

Interaction with and assessment by clinical research personnel on a fixed schedule, with the pharmacotherapeutic alliance assessed both by research personnel and subjects.

Limitations and Caveats
Individuals entering this study were aware that they might be assigned to a treatment condition that did not involve the use of medication; it is not certain that they are representative of people with MDD who would enter clinical trials for MDD.
