Abstract: BACKGROUND: Social phobia is a chronic disorder that results in substantial impairment. We conducted a qualitative review of randomized controlled trials (RCTs) of psychological interventions for social phobia. METHOD: Articles were identified through searches of electronic databases and manual searches of reference lists. They were classified by psychological interventions evaluated. Data regarding treatment, participants and results were then extracted and tabulated. We identified which psychological interventions are empirically supported, using the scheme proposed by Chambless & Hollon (Journal of Consulting and Clinical Psychology 1998, 66, 7-18). RESULTS: Thirty studies evaluating the efficacy of social skills training (SST), exposure therapy and/or cognitive treatments were identified. Cognitive behavior therapy (CBT), involving cognitive restructuring and exposure to feared and avoided social situations or behavioral experiments, was found to be an efficacious and specific treatment for social phobia. Exposure therapy was found to be an efficacious treatment since most of the evidence of its efficacy was from comparisons with no treatment. There were mixed findings regarding the relative efficacy of CBT and in vivo exposure. Some studies reported that the interventions were equivalent, while others found that patients treated with CBT had a better outcome. There was little evidence to support the use of SST. CONCLUSIONS: CBT is the psychological intervention of choice for social phobia. The findings of this review are compared to those of other major reviews and limitations are discussed.

Abstract: BACKGROUND: Several studies have identified increased medical problems among individuals with panic disorder (PD). We previously found that specific conditions--interstitial cystitis (IC), mitral valve prolapse (MVP), migraines, and thyroid disorders--aggregated non-randomly among panic families (we called this the "PD syndrome") and that families with and without the syndrome were genetically distinguishable on chromosome 13. We present data from a new case-control study that replicates and extends the syndrome phenotype clinically. METHODS: Probands with a definite diagnosis and family history of PD (n=219), social anxiety disorder (SAD; n=199), or both (n=173) and 102 control subjects with no personal/family history of anxiety were interviewed with the SADS-LA diagnostic instrument. Medical history was obtained via medical checklist and the family history screen; IC symptoms were assessed with criteria developed by the National Institute for Diabetes and Digestive and Kidney Diseases. Subjects and interviewers were unaware of the syndrome hypothesis; final best-estimate diagnoses were blind to syndrome data. RESULTS: Probands with PD or SAD, as compared with control subjects, were five or more times as likely to report IC symptoms and twice as likely to report MVP and migraines (other genitourinary and cardiovascular problems were not elevated). First-degree relatives of probands with PD or SAD were also at increased risk for IC, MVP, thyroid problems, and headaches, regardless of whether the proband reported the same condition. CONCLUSIONS: These findings are consistent with previous data supporting a PD syndrome and further suggest that this syndrome might include other anxiety disorders well.
