Abstract
The aim of the present study was to identify and synthesize recent research findings in the aetiology and psychological treatment of social anxiety disorder and consider how these might improve outcome through more effective intervention. The electronic databases Medline, EMBASE and PsychInfo were searched for January 2000–December 2008. Publications of interest referred to in relevant articles were also reviewed. Case reports and publications not in English were excluded. The greatest variance in social anxiety disorder is accounted for by temperamental and personality factors and these may be associated with significant heritability. The environmental contribution is smaller and mainly due to non-shared factors, with a small contribution from shared environmental factors. Epidemiological research confirms that social anxiety disorder is chronic, and among the anxiety disorders has the lowest rates of treatment seeking, receipt of evidence-based treatments and recovery. Effective psychological treatments have been available for some time, and the research emphasis is on increasing the efficacy of treatments through innovations in programme content and delivery. Cognitive science research has contributed a better understanding of cognitive factors that maintain social anxiety disorder and informed enhancement of the cognitive elements of therapy. Internet-based programmes show promise as a novel way to deliver and improve access to effective therapy. Genetic, personality and temperamental factors contribute to the risk for social anxiety disorder. Given the associated comorbidity and disability, energy needs to be directed towards early recognition and treatment, and to increasing engagement and retention in effective therapy. Ongoing professional education is required to ensure that the disorder is recognized and evidence-based treatments received by patients who do seek help. Current cognitive behavioural treatments are being enhanced as the results of cognitive science research are being applied, and novel forms of treatment delivery show promise in increasing access.
