title: Social anxiety symptoms across diagnoses among outpatients attending a tertiary care mood and anxiety disorders service.
abstract: BACKGROUND
  Social phobia is a common, persistent and disabling anxiety disorder in which co-existing depressive symptoms are common. However the prevalence of social anxiety symptoms in patients with other mood and anxiety disorders is uncertain.
  
  
  METHODS
  In consecutive patients attending a tertiary referral mood and anxiety disorders service, depressive symptoms were assessed by the Montgomery-Asberg Depression Rating Scale (MADRS) and social anxiety symptoms by the Liebowitz Social Anxiety Scale (LSAS). The Clinical Global Impression of Severity (CGI-S) was completed following the appointment.
  
  
  RESULTS
  75 patients (48 women, 27 men; mean age 45.9 years) completed the study. 38 had a single diagnosis and 37 co-morbid diagnoses: 15 patients had bipolar disorder, 35 unipolar depressive disorder, 19 an anxiety disorder, and 6 other disorders. Independent samples t-tests and one-way between-subjects ANOVA revealed that the severity of social anxiety symptoms but not depressive symptoms was significantly greater in patients with co-morbid diagnoses (LSAS 73.7 vs 54.2, t(72)=2.44, p<.05; MADRS 21.9 vs 18.0, t(73)=1.76, p=.08; CGI-S 3.7 vs 3.2, t(73)=2.64, p<.05); and in anxiety disorders than in unipolar depression or bipolar disorder (respectively; LSAS 78.8 vs 59.4 vs 50.0, F(2, 65)=3.13, p=.05; MADRS 22.2 vs 19.8 vs 17.5, F(2, 66)<1, ns; CGI-S 3.9 vs 3.3 vs 3.1, F(2, 66)=5.43, p<.01). In the overall sample, correlation coefficients were MADRS and LSAS, R(2)=0.2628, p<.001; MADRS and CGI-S, R(2)=0.5863, p<.001; and LSAS and CGI-S, R(2)=0.327, p<.001. Correlations between MADRS and LSAS scores were higher in bipolar disorder (R(2)=0.4900, p<.01) than in unipolar depression (R(2)=0.376, p<.01) or anxiety disorders (R(2)=0.0041, ns).
  
  
  CONCLUSIONS
  Small size of convenience sample undergoing varying treatments within a single specialist tertiary referral centre.
  
  
  CONCLUSIONS
  There was only a moderate correlation between depressive and social anxiety symptoms across a range of diagnoses. Depressive and social anxiety symptoms were most severe but least well correlated among tertiary care outpatients with anxiety disorders, emphasising the need for comprehensive evaluation and treatment.
