This study aimed to assess the relationship between clinical and behavioral manifestations of the Social Anxiety Disorder (SAD) and verify the discriminative validity of the Social Skills Inventory (SSI-Del-Prette) in the diagnosis of this disorder. The participants were 1,006 undergraduates, aged between 17 and 35 years old, both genders. Subsequently, 86 participants were randomly selected from the initial sample and grouped as SAD cases and non-SAD cases through systematic clinical evaluation. The results indicated that the more elaborate the repertoire of social skills of an individual is, the lower his/her likelihood of meeting the screening criteria of diagnostic indicators for SAD. Furthermore, the SSI-Del-Prette has demonstrated to significantly distinguish individuals with and without SAD, evidencing, thus, its discriminative validity.
