Abstract
Preventive interventions, such as universal and targeted, i.e. selective and indicated, interventions can effectively reduce the incidence of anxiety disorders and thus lower the high individual and socioeconomic burden of anxiety disorders. This review article provides an overview of internationally established prevention programs for children, adolescents and adults. The efficacy and cost effectiveness of preventive interventions are discussed. Due to the large target group, universally implemented strategies are costly and organizationally complex but can prevent a large number of manifest anxiety disorders or reduce the clinical expression, despite only small effect sizes. Selective preventive measures are aimed at persons with a high risk for anxiety disorders (e.g. with high anxiety sensitivity, behavioral inhibition, harm avoidance, family history of anxiety disorders). The indicated preventive interventions in high-risk individuals with first subclinical anxiety symptoms are successful in preventing the manifestation of anxiety disorders and constitute the most cost-effective type of preventive measures. Biological, i.e. genetic, imaging or neurophysiological markers, or their combination, are discussed as promising future targets for selective or indicated prevention of anxiety disorders.
