Reducing Anxiety and Stress in Primary Care Patients

VA Office of Research and Development35 enrolled

Overview

Anxiety is common among primary care patients, but is undertreated. The purpose of this study is to evaluate whether a brief anxiety treatment designed for VA primary care is more effective at reducing anxiety symptoms in Veterans compared to usual care. The investigators will also examine whether Veterans like the brief treatment and whether the treatment can be feasibly delivered in primary care. Forty-eight adult Veteran primary care patients from the Syracuse VAMC who are experiencing anxiety symptoms will be recruited and randomly assigned to receive the brief anxiety treatment or usual care. The brief treatment consists of up to six 30-minute sessions with a cognitive-behavioral skills focus. The investigators will compare anxiety symptom severity between the two groups at baseline and at post-assessment 16 weeks later.

Background/Rationale: Many Veteran primary care patients experience impairing symptoms of anxiety, but rates of treatment are low. Primary Care-Mental Health Integration (PC-MHI), in which mental health clinicians provide brief treatment in the primary care setting, can bridge the gap between demand for, and availability of, anxiety treatment. However, brief anxiety interventions suitable for use in the PC-MHI setting are needed. Developing an effective brief PC-MHI intervention for anxiety would address a gap in VA treatment options and facilitate high quality healthcare that improves treatment engagement, clinical outcomes, and patient experience. To ensure maximum reach, this intervention should accommodate a variety of subthreshold and diagnostic anxiety presentations, as well as comorbid depression. Objectives: The overall goal of this research program is to develop, refine, and evaluate a brief anxiety intervention that will be acceptable to Veterans and feasible for PC-MHI providers. The primary aim of the current study is to conduct a pilot randomized controlled trial to evaluate feasibility, acceptability, potential implementation barriers and facilitators, and effectiveness of the intervention compared to usual care. Methods: This will be a pilot hybrid type I effectiveness-implementation randomized controlled trial (N = 35). The primary goal is to evaluate feasibility, acceptability, and effectiveness of the intervention in reducing anxiety symptom severity compared to usual care. The secondary goal is to collect preliminary data on implementation barriers and facilitators that may affect future real-world uptake.

Outcomes

Primary Outcomes

Generalized Anxiety Disorder-7 at Post-Assessment

The primary outcome of anxiety symptom severity will be measured by the Generalized Anxiety Disorder-7 (GAD-7) self-report questionnaire, a validated measure that is widely used in VA primary care. Participants rate how much they have been bothered by each of 7 anxiety symptoms over the last 2 weeks on a Likert scale from 0 (not at all) to 3 (nearly every day). Scores are summed to create a total score ranging from 0 to 21 indicating severity of anxiety symptoms; higher scores indicate more severe symptoms. The total score is sensitive to change from treatment across the anxiety disorders. The GAD-7 has demonstrated reliability and validity and is a good screening tool for multiple anxiety disorders.

Time frame: Baseline & Post-Assessment (at 16 weeks)

Secondary Outcomes

Patient Health Questionnaire-9 at Post-Assessment

The secondary outcome of depressive symptom severity will be measured by the Patient Health Questionnaire-9 (PHQ-9) self-report questionnaire, a validated measure that is widely used in VA primary care. Participants rate how often they have been bothered by each of 9 symptoms over the last 2 weeks on a Likert scale from 0 (not at all) to 3 (nearly every day). Scores are summed to create a total score from 0 to 27 indicating severity of depressive symptoms; higher scores indicate greater severity. The total score is sensitive to change from treatment. The PHQ-9 has demonstrated reliability and validity.

Time frame: Baseline & Post-Assessment (at 16 weeks)

Depression Anxiety Stress Scale-21 Anxiety Subscale Change

The secondary outcome of anxiety symptoms will be measured with the Depression Anxiety Stress Scale-21 (DASS-21) Anxiety Subscale. Participants indicate how much each of 7 items applies to them over the past week on a scale from 0 (did not apply to me at all) to 3 (applied to me very much, or most of the time). Scores are summed and multiplied by 2 to create a total score ranging from 0 to 42; higher scores indicate higher anxiety symptoms. This measure has good psychometric properties in both clinical and non-clinical samples. The DASS-21 reliably distinguishes between symptoms of anxiety (panic/worry), stress (tension/agitation), and depression (low mood/anhedonia), which are highly comorbid.
