Risk factors associated with the development of anxiety disorders have been identified; however, the development of preventive interventions targeting these risk factors is in the nascent stage. To date, preventive interventions have tended to target specific anxiety disorder symptoms (e.g., panic attacks). Although these interventions are effective at reducing risk for the targeted disorder (e.g., panic disorder), the focus of the intervention is narrow, thereby limiting the dissemination of these interventions. One approach that may broaden the scope of our prevention efforts is the development of a transdiagnostic intervention. Currently, transdiagnostic interventions have only been used in those with diagnosed conditions (e.g., anxiety disorders); however, it stands to reason that a transdiagnostic approach may also be helpful for those at-risk for developing anxiety disorders. The present study reported on the development and use of a brief preventative intervention for those with subclinical anxiety (i.e., worry, social anxiety). Participants were randomized into either a transdiagnostic preventative intervention, focused on reduction of safety aids, or a health focused control group. Participants consisted of sixty-nine individuals with subclinical levels of anxiety. Results revealed significant between group differences in the reduction of social anxiety, worry, and levels of impairment with the active intervention group relative to the control group. Further, change in safety aid utilization was a significant mediator in the association between intervention group and social anxiety and worry at Week 1; however, it was not a significant mediator at Month 1. Implications of these results and avenues for future research are discussed.
