Abstract:
Anxiety disorders and related traits have become increasingly relevant to the study of physical health and health behaviors over the years. One important health behavior is healthcare utilization, and both over- and under-use have important implications within both personal and public health domains. Anxiety disorders are associated with reassurance-seeking, avoidance behaviors, and other characteristics and traits that may impact patterns of healthcare utilization. The current paper reviews the literature on the known associations between anxiety disorders and healthcare utilization, including studies (N = 70) that examined the association of healthcare utilization with generalized anxiety disorder, social anxiety disorder, panic disorder and agoraphobia, dental and blood-injection-injury phobias, and illness anxiety disorder/health anxiety. Overall, the majority of the studies reviewed indicate that anxiety disorders and health anxiety are associated with increased healthcare utilization across multiple care settings. In addition, there is preliminary but limited evidence that, in some cases, anxiety can be associated with delayed, irregular, or inconsistent use of healthcare services. More work is needed to fine-tune our understanding of the impact of anxiety disorders in healthcare settings.
