Reducing the Burden of Depression Related Disability

Study Overview
=================
Brief Summary
-----------------
The purpose of this research study is to test the effectiveness of a new telephone counseling program for employed Veterans with depression called the Veterans Work and Health Initiative (V-WHI) using the Be Well at Work (BWAW) intervention. 250 participants will be recruited and randomly assigned to one of two groups: the V-WHI experimental group or usual mental health care. The V-WHI counselors will address mental health and job-related issues that interfere with working. This counseling is provided solely over the phone with sessions every 2 weeks for 4 months (eight sessions total). At 8 months post-baseline, the V-WHI group is provided with a booster session. Participants in both groups are administered follow-up questionnaires at two time-points: month four and month nine.

Detailed Description
-----------------
With the goal of helping employed Veterans with depression to participate fully in the labor market, this randomized controlled trial has two objectives: 1) test the effectiveness of a new evidence-based, vocationally-focused telephonic counseling program for employed Veterans with depression, the Veterans Work and Health Initiative (V-WHI), which was developed by this study's research partners from the Tufts Medical Center; and 2) if the V-WHI is effective, quantify its return on investment. This study will test the impact of the BWAW intervention in combination with the Philadelphia VA's Primary Care Mental Health Integration program, the Behavioral Health Lab (BHL). For the main hypothesis, concerning the effect of BWAW, the primary endpoint is the post-intervention at-work mean productivity loss score based on the validated Work Limitation Questionnaire (WLQ) adjusted for baseline score. For Hypothesis 2, concerning maintenance of post-intervention effects at nine months, the primary outcome is the mean difference of the change in productivity loss score. For hypothesis 3, the primary outcome was the return on investment (ROI) from BWAW. After informed consent and eligibility screening, subjects are randomized to one of two groups: the V-WHI intervention group or to the usual care group (BHL). 250 employed Veterans with depression and work limitations will be enrolled (half per group). The usual care group participants are assigned to standard behavioral health care. The second group, assigned to BWAW intervention, is the experimental group. Participants in this group are assigned to an innovative program designed explicitly to address mental health and vocational issues that interfere with working in addition to standard care. V-WHI counselors offer work coaching and modification strategies and work-focused cognitive behavioral therapy (CBT). This counseling is provided solely over the phone with sessions every 2 weeks for 4 months (eight sessions total). At 8 months post-baseline, the V-WHI group is provided with a booster session. Participants in both groups are administered follow-up questionnaires at two time-points: month four (post-intervention) and month nine.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Improvement in Work Related Disability Post Intervention | The outcome measure is the mean difference of the changes from baseline to time 1. The mean differences are then compared. The WLQ scale range=0-25 with higher scores indicating greater difficulty. | 4 months post randomization | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sustained Improvement in Work Productivity | The outcome measure is the mean difference of the changes from baseline until about 9 months post randomization. The mean differences are then compared. The WLQ scale range=0-25 with higher scores indicating greater difficulty. | 9 months post randomization | 
| The Outcome is the Return on Investment (ROI) Obtained From Implementing the V-WHI Experimental Intervention. | This variable is defined as: [marginal benefit on patient work productivity attributable to the V-WHI intervention] - [marginal cost of supplementing IC with V-WHI) / [marginal cost of supplementing IC with V-WHI]. The comparison assessed the monetized value of the difference in pre to post treatment changes in at-work productivity loss (presenteeism) + the monetized value of the difference in the changes in productivity loss due to work absences. Because both productivity loss components were measured at baseline and two follow-ups, the changes between time points (baseline to month 4 and month 4 to month 8/9) were first averaged before computing their difference. The marginal costs attributable to V-WHI included the full costs of the providing the counseling treatment and supervision of the counselors. | 9 months post randomization |
