Do Youth with Separation Anxiety Disorder Differ in Anxiety Sensitivity From Youth with Other Anxiety Disorders?

Studies on the relationship between separation anxiety disorder (SAD) in childhood and panic disorder (PD) in adolescence and adulthood have yielded results which suggest a common underlying vulnerability for both disorders. In this study, we examined whether one such possible vulnerability-anxiety sensitivity-differed for youth diagnosed with SAD versus other anxiety disorders. Anxiety sensitivity was assessed using the Childhood Anxiety Sensitivity Index (CASI) in 315 clinic-referred youth (ages 6-17, 113 girls). 145 children (46%) were diagnosed with one or more primary anxiety disorder, including SAD (n = 22), generalized anxiety (GAD) (n = 79), social anxiety (SocA) (n = 55), and specific phobia (SP) (n = 45). Children with SAD reported higher levels of anxiety sensitivity and fears of physical symptoms than children with SP and SocA, but not children with GAD. We speculate that children who have SAD and GAD and high anxiety sensitivity may be more vulnerable to develop PD.
