Mental Health Link for Veterans Referred to Mental Health Services (MHL)

Background: Depression is one of the most prevalent mental health concerns among Veterans. Nearly 1 in 6 Veterans has the disorder at any given time and 50% of Veterans meet criteria for depression at some point in their lives. Depression is associated with significant adverse outcomes, and untreated can result in drug abuse, poor health outcomes, suicide and other-cause mortality. Adults with depression often delay and underutilize treatment, and such delays in care are associated with low treatment utilization.

Significance: Psychotherapy utilization rates for depression among Veterans over the past two decades have stayed below 34%. VHA has organizational priorities to decrease system barriers through various strategies. Despite these efforts, the VHA has a critical national staffing shortage. Fortunately, mental health visit wait times can be leveraged as an opportune moment to support and prepare Veteran patients for upcoming visits. Currently, there are no tools to provide support to Veterans while they wait for mental health services.

Innovation and Impact: To address this gap in care, our team developed and pilot-tested Mental Health Link (MHL),an innovative solution that does not rely on reducing wait times, but rather leverages wait times to provide support and prepare Veterans for care. MHL is a semi-autonomous text-based tool designed to improve emotional and symptom awareness, and provide support during wait periods through sharing easy to implement coping strategies.

Specific Aims. Aim 1: Determine the effect of MHL on psychotherapy initiation and adherence (number of sessions completed). Aim 2: Determine the effect of MHL on emotional awareness, a sense of connectedness, and satisfaction with the VA and mental health service. Aim 3: Identify determinants, strategies, and perceived outcomes in a subsample of MHL users (n = 24) and their providers (n = 24) to inform an implementation research logic model and intervention mapping.

Methodology: The investigators propose a 3-site, 5-year mixed-method hybrid I randomized control trial (RCT) using an altered Zelen design to compare MHL to usual care in a sample of Veterans (N = 192) referred to psychotherapy for depression. In Aim 1, the investigators will employ logistic regression and poison regression to estimate the difference between the intervention and control groups in treatment initiation rates and number of sessions (i.e., treatment adherence), respectively. In Aim 2, the investigators will employ repeated measures MANCOVAs to test for the interaction between time and group on proposed outcomes: positive and negative emotional awareness, sense of connectedness and satisfaction. For Aim 3 the investigators will use a qualitative matrix-analysis framework to analyze focus group data to identify other factors related to Aims 1 and 2 outcomes for triangulation and key determinants of implementation of MHL into clinical flow. Next Steps/Implementation. By identifying determinants of implementation the investigators will target facilitators and barriers to integrate MHL into the mental health service workflow. This work will also provide evidence of effectiveness outcomes. Overall, findings will facilitate the development of a follow-up Merit, Type II Hybrid RCT, focused on implementation and effectiveness outcomes. In the long-term, this work will support the implementation and sustainment of evidence-based mental health and suicide prevention practices by optimizing access to care, using value-based care systems.
