  Purpose

This study will determine whether the addition of Cognitive Therapy (CT) to antidepressant medication (ADM) enhances treatment for depression. This study will also test whether the addition of CT to ADM will prevent recurrences of depression after therapy is over.

Further study details as provided by Vanderbilt University:

Primary Outcome Measures:
  • Number of Participants in Remission According to the Longitudinal Interval Follow-up Evaluation (LIFE) and the Hamilton Rating Scale for Depression (HRSD) [ Time Frame: Through month 18 of treatment ] [ Designated as safety issue: No ]
    Remission defined as four consecutive weeks of LIFE Problem Symptom Rating (PSR) values of 2 or less and HRSD scores of 8 or less for four consecutive weeks (with partial remission defined as LIFE PSR values of 3 or less and HRSD scores of 12 or less after month 12 only)

  • Number of Participants in Recovery According to the LIFE and HRSD [ Time Frame: Through 36 months of treatment ] [ Designated as safety issue: No ]
    Six consecutive months following remission without relapse (two weeks of elevated LIFE PSR scores of 4 or more and HRSD scores of 14 and above)

  • Number of Participants in Recurrence According to the LIFE and HRSD [ Time Frame: Measured up to Month 36 from recovery ] [ Designated as safety issue: No ]
    Recurrence defined as two consecutive weeks of elevated LIFE PSR scores of 5 or above and HRSD scores of 16 or above (three weeks during period of medication withdrawal)


Other Outcome Measures:
  • Serious Adverse Events [ Time Frame: Thorought study ] [ Designated as safety issue: Yes ]
    Serious Adverse Events (SAEs) as reported to the Institutional Review Boards and Data Safety Monitoring Board throughout the duration of the study

Arms Assigned Interventions
Experimental: Cognitive therapy plus medications
Participants will receive antidepressant medication plus cognitive therapy
Behavioral: Cognitive Therapy
CT sessions occur weekly during acute treatment and monthly during continuation. Acute treatment may last up to 18 months. Remitted patients are continued on medication for up to 36 months from initial randomization until they meet criteria for recovery. At recovery, patients receiving combined treatment discontinue CT.
Other Name: CT
Drug: Medications
Antidepressant medication is distributed as clinically indicated with augmentation and ancillary medications as needed. Acute treatment may last up to 18 months. Remitted patients are continued on medication for up to 36 months from the point of initial randomization until they meet criteria for recovery. All recovered patients are randomized a second time to either maintenance medication or medication withdrawal. Patients are then monitored over 36 months to ascertain risk for recurrence of depressive symptoms.
Other Name: ADM
Experimental: Medications alone
Participants will receive maintenance of antidepressant medication alone
Drug: Medications
Antidepressant medication is distributed as clinically indicated with augmentation and ancillary medications as needed. Acute treatment may last up to 18 months. Remitted patients are continued on medication for up to 36 months from the point of initial randomization until they meet criteria for recovery. All recovered patients are randomized a second time to either maintenance medication or medication withdrawal. Patients are then monitored over 36 months to ascertain risk for recurrence of depressive symptoms.
Other Name: ADM

Detailed Description:

It is commonly believed that the combination of ADM and psychotherapy is more effective in treating depression than either treatment alone. Data indicate that CT enhances the initial effects of ADM, but little research has been conducted to determine whether prior exposure to CT prevents the onset of new depressive episodes. This study will determine the effectiveness of adding CT to ADM for the treatment of depression.

Participants are randomly assigned to receive either ADM alone or ADM plus CT for up to 18 months. Remitted patients are continued on medication for up to 36 months from the point of initial randomization until they meet criteria for recovery. At recovery, patients receiving combined treatment discontinue cognitive therapy; all recovered patients are randomized a second time to either maintenance medication or medication withdrawal. Patients are then monitored over 36 months to ascertain risk for recurrence of depressive symptoms.
