MPA First Friday Forum: Population-Based Approaches to Managing Anxiety Disorders
Anxiety disorders are the most common mental health condition in the United States, affecting approximately one-third of the population.1 They frequently co-occur with depression, substance, and other anxiety-related conditions. Anxiety disorders are disproportionately associated with a variety of chronic disease risk factors, such as nicotine use, alcohol consumption, and sedentary behaviors, and chronic diseases, such as cardiovascular disease, diabetes, and asthma.2 The public health impact of untreated anxiety disorders is staggering. The adjusted estimated annual economic impact of anxiety disorders is $62 billion through disability, lost wages, and healthcare costs.3 Although highly effective treatments exist for anxiety, only a minority of patients with clinical anxiety receive some form of care. Unfortunately, even among those individuals being actively treated for their anxiety disorder, very few are receiving pharmacotherapy and/or psychotherapy that meet evidence-based practice guidelines.4
Cognitive behavioral therapy (CBT), especially exposure-based interventions, is the most effective treatment for anxiety disorders. 5 CBT is highly acceptable to patients, and typically outperforms evidence-based pharmacotherapy in the longer-term maintenance of treatment gains.6 Although access to CBT remains challenging, large-scale efforts are being made to change health care delivery systems to improve the dissemination of evidence-based treatments.
