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.

| Hamilton Rating Scale for Depression | scale for depressive symptoms administered by trained rater. The HRSD 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. Although the HRSD list 21 items, the scoring is based on the first 17 items. sum of the scores of the first 17 items (range from 0 to 54): 0-7 = NORMAL 8-13 = Mild Depression 14-18 = Moderate Depression 19-22 = Severe Depression >=23 = Very Severe Depression | Baseline week |

| Hamilton Anxiety Rating Scale (HARS) 14-item Scale | Scale for anxiety symptoms administered by trained rater. The HARS 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 indi-cates mild severity, 18-24 mild to moderate severity and25-30 moderate to severe. |

| CGI Severity and Improvement | scales developed to measure the clinician's view of subjects' global functioning before and after initiating a study medication. The CGI correlates well with other standard outcome measures for depression (e.g., HRSD), is sensitive to change in antidepressant trials, and offers clinically understandable anchor points. 7-point scale: 0 = Not assessed 4 = Moderately ill 1 = Normal, not at all ill 5 = Markedly ill 2 = Borderline mentally ill 6 = Severely ill 3 = Mildly ill 7 = Among the most extremely ill patients | Baseline week |
| Treatment Emergent Symptom Scale | rating scale for physical symptoms reported during the study. This is a standard means of recording drug-related adverse effects that will allow us to assess whether contact frequency is associated with differences in side effects among study subjects. | Baseline week |
| California Pharmacotherapy Alliance Scale (CALPAS)-Clinician Version | 24 item Likert scale rating the clinician's assessment of the therapeutic alliance, particularly about medication issues, with the patient. This scale is superior to other therapeutic alliance scales because it is focused on drug treatment and does not contain items specific to psychotherapy. Prior studies using the CALPAS reported an association between therapeutic alliance and outcome, and some studies found alliance mediated the effect of expectancy on depression outcome. | Baseline week |
| Blind Assessment-Clinician Version | Rates clinician's guess as to the identity of study medication and the confidence in that guess. This assessment is necessary to document the effectiveness of the study's methods of treatment allocation concealment. | 8 weeks |
| Quick Inventory of Depressive Symptoms-Self Report (QIDS-SR) 16 Item Scale | rating scale for depressive symptoms based on DSM criteria. A self-report measure for depressive symptoms is valuable in this study, because it is less susceptible to clinician and rater bias. The QIDS-SR has been increasingly used in antidepressant studies (e.g., STAR*D) due to its equivalent weightings for each symptom item, clearly understandable anchor points, and inclusion of all DSM criteria for depression | 8 Weeks |
| Treatment Credibility and Expectancy Scale (CES) | 8 item scale in which subjects rate their impression of the credibility of the treatment and how they estimate their expectation of improvement. The CES is the most widely used measure of expectancy and has demonstrated good psychometric properties in multiple studies. For this study, the primary measure of expectancy will be item 4: "By the end of the treatment period, how much improvement in your depressive symptoms do you think will occur?" (0-100%). | 8 Weeks |
| Client Satisfaction Questionnaire 8 (CSQ 8) | self-administered scale with items rating respondents' satisfaction with mental health services they are receiving on a 4 point Likert scale. Use of the CSQ 8 will allow us to determine whether CFM and RFM are associated with differences in participant satisfaction. | 8 Weeks |
| Cornell Treatment Preference Index | scale used in mental health studies to document the type and strength of patients' treatment preferences. We will use a modified version in this study asking subjects "Based on your experience and how you feel right now, which of the visit frequencies in this study would be your first choice?" The strength of this preference will be measured on a 5-point Likert scale. | 8 weeks |
| Revised Life Orientation Test (LOT-R) | scale developed to assess individual differences in generalized optimism versus pessimism. Degree of optimism on this scale has been correlated with the magnitude of placebo response observed in studies of placebo analgesia, and we will determine whether LOT-R scores moderate effects of therapeutic contact. | 8 weeks |
| Schedule for Adaptive and Nonadaptive Personality (SNAP) | this questionnaire is a widely used assessment tool for personality disorders that we will also use to identify predictors of response to varying visit frequency. | 8 weeks |
| California Pharmacotherapy Alliance Scale (CALPAS)-Patient Version | 24 item Likert scale rating the patient's assessment of the therapeutic alliance, particularly about medication issues, with the clinician.
