Objective: Anxiety is a complex phenomenon on which culture has a prominent influence. The present study aimed to investigate the cultural aspects of social Anxiety disorder (SAD) in an Iranian population. Method: A qualitative content analysis research was done to answer the study question. A total of 16 individuals with social Anxiety disorder (six men and 10 women) were selected using purposeful sampling method (M = 24. 43, SD = 4. 56). The study was conducted in Tehran, Urmia, and Sanandaj-Iran. Participants were from different ethnic backgrounds (LOR, FARS, TURK, and KURD). Data were analyzed by thematic analysis using an inductive method. Results: Analysis of participants’ records yielded five distinct categories with some subcategories, which are as follow: (1) Anxiety experiences; (2) core beliefs; (3) reasons of being anxious; (4) effects of SAD on life aspects; and (5) coping strategies. Conclusion: It seems that symptoms of social Anxiety and its underlying beliefs, causes and effects and coping strategies are almost experienced and interpreted in a way that could be the same as DSM-5 clinical presentation of social Anxiety, with the exception that somatic symptoms are experienced by almost all participants.
