Telephone Administered Psychotherapy for the Treatment of Depression for Veterans in Rural Areas

Phase 2

Completed

• Conditions: Depression; Depressive Disorder
• Interventions: Behavioral: Telephone cognitive behavioral therapy

• Registration Number: NCT00223652
• Lead Sponsor: US Department of Veterans Affairs

Brief Summary

The purpose of this study is to examine the efficacy of telephone-administered cognitive-behavioral therapy (T-CBT) in treating major depression among veterans served by community-based outpatient clinics (CBOCs) in the Veteran's Integrated Service Network (VISN) 21, which serves rural areas in Northern California and (VISN) 12, which serves rural areas surrounding the Hines, IL VA Hospital.

Detailed Description

More than 20% of patients in primary care have depressive disorders. While primary care is the principal venue for treatment for depression, fewer than 25% of depressed patients receive adequate treatment for their depression. These outcomes can be worse when there are barriers to treatment such as living in a rural area. Several studies have found that given a choice, about two-thirds of depressed primary care patients prefer psychotherapy or counseling over antidepressant medication.

This is a controlled, randomized trial in which subjects meeting criteria for major depressive disorder (MDD) from primary care settings in VISN 21 including CBOCs will be randomly assigned to one of two conditions: 1) a 16-session manualized telephone administered cognitive behavioral therapy (T-CBT) delivered over 20 weeks or 2) a treatment-as-usual (TAU) condition. Telephone-administered cognitive behavioral therapy (T-CBT) is an intervention aimed at improving coping skills and social functioning. It is divided into two phases: 1) an initial treatment phase consisting of 12 weekly sessions aimed at reducing symptoms of depression, and 2) a booster phase in which 4 sessions are provided at increasingly greater intervals to target maintenance of treatment gains. T-CBT, administered by doctoral level psychologists, will be compared to a treatment-as-usual (TAU) condition that controls for the natural course of depression during the course of treatment.

Primary Outcome Measures

Name	Time	Method
Change in Severity of Depression Using the Patient Health Questionnaire-9	Baseline, Week 12, Week 20	Self-reported depression was measured using the Patient Health Questionnaire-9 (PHQ-9).; Data across the three time points (baseline, Week 12, Week 20) were analyzed using a mixed-effects repeated measures model with random subject-specific intercepts for continuous outcome PHQ-9. PHQ-9 scores of 5, 10, 15, and 20 represent mild, moderate, moderately severe and severe depression, respectively.; PHQ-9 score ranges from 0-27, higher values indicate more severe depression.
Number of Participants Meeting Criteria for Major Depressive Disorder	Baseline to week 12, and week 20	Veterans meeting criteria for major depressive disorder were randomized to receive 16 session of T-CBT over 20 weeks or treatment as usual through the CBOC. Generalized estimating equations models with exchangeable working correlation structure was used for the binary outcome (MDE). A veteran was required to meet diagnostic criteria for severe psychiatric disorder(e.g., psychotic, bipolar, or dementia disorder; post-traumatic stress disorder \[PTSD\] patients were not excluded). DSM-IV diagnosis was assessed using the full Mini International Neuropsychiatric Interview at baseline, whereas the major depressive episode(MDE) module was administered at follow-up.
Change in Severity of Depression Using Hamilton Depression Rating Scale	Baseline, 12 weeks, 20 weeks	Evaluators administered the Hamilton Depression Rating Scale(Ham-D).; Veterans were assessed at baseline,12 weeks, 20 weeks(posttreatment), and 6-month follow-up using the Ham-D. Self-reported depression was measured using the Hamilton Depression Rating Scale(Ham-D).; Data across the three time points (baseline, Week 12, Week 20) were analyzed using a mixed-effects repeated measures model with random subject-specific intercepts for continuous outcome Ham-D.; Ham-D ranges from 0-52, higher values indicate more severe depression. A score of 0-7 is considered to be normal. Scores of 20 or higher indicate moderate, severe, or very severe depression.

Secondary Outcome Measures

Name	Time	Method
Maintenance of Treatment Effect	6-month post treatment follow-up	6-month post treatment follow-up on outcome measure of the Patient Health Questionnaire-9 (PHQ-9).; Data was analyzed using a mixed-effects repeated measures model with random subject-specific intercepts for continuous outcome PHQ-9.; PHQ-9 score ranges from 0-27, higher values indicate more severe depression. PHQ-9 scores of 5, 10, 15, and 20 represent mild, moderate, moderately severe and severe depression, respectively.
Number of Participants Meeting Criteria for Major Depression Disorder at 6 Month Follow-up	6-month follow up at week 44 post treatment	Veterans meeting criteria for major depressive disorder were randomized to receive 16 session of T-CBT over 20 weeks or treatment as usual through the CBOC. Generalized estimating equations models with exchangeable working correlation structure was used for the binary outcome (MDE).; A veteran was required to meet diagnostic criteria for severe psychiatric disorder(e.g., psychotic, bipolar, or dementia disorder; post-traumatic stress disorder \[PTSD\] patients were not excluded). DSM-IV diagnosis was assessed using the full Mini International Neuropsychiatric Interview at baseline, whereas the major depressive episode(MDE) module was administered at follow-up.
