Psychological Treatment of Co-occurring Anxiety Disorders in Clinical Practice: A Vignette Study

'Background and Objectives' Many individuals with anxiety difficulties present with co-occurring anxiety disorders yet no evidence-based guidelines exist on how to treat this presentation. The present study investigated how Australian psychologists approach treating co-occurring anxiety disorders. 'Methods' A total of 169 psychologists practicing in Australia undertook an online survey consisting of open-questions relating to the treatment of DSM-IV anxiety disorder diagnoses and reported practice in relation to two clinical vignettes. Participant responses were coded using a directed content analysis approach. 'Results' The majority of psychologists reported utilising cognitive behaviour therapy (CBT) interventions in the treatment of single and co-occurring anxiety disorders but not specific evidence-based treatment guides or protocols. The majority of the psychologists surveyed reported that they adopt a transdiagnostic approach to addressing co-occurring anxiety disorders. 'Conclusions' Psychologists typically do not follow a specific treatment guide in the treatment of anxiety disorders and judge a transdiagnostic approach incorporating CBT techniques as the best way to treat comorbidity. More effort may be needed to disseminate evidence-based interventions for anxiety disorders and for authors of empirically supported treatments to provide clear guidelines regarding treating co-occurring anxiety disorders.
