Both groups completed: (1) The Weschler Abbreviated Scale of Intelligence (WASI); (2) The Liebowitz Social Anxiety Scale (LSAS; Liebowitz, 1987), a measure designed to assess social fear and avoidance; (3) the Beck Depression Inventory-II (BDI; Beck, 1961; Beck Steer and Garbin, 1998), administered to assess the overall severity of depressive symptoms and to verify that the SAD group did not have significant mood symptoms.
