A preliminary attempt was made to assess the prevalence of social phobia among patients attending a psychiatric outpatient clinic in Riyadh over a period of one year. The demographic characteristics of the patients presenting with the disorder were also examined. The results confirm our earlier impressions that this disorder is very frequent among our patients. Cases diagnosed as social phobia comprised 79.8% of phobic disorders, 20.3% of neurotic disorders, and 9.2% of all psychiatric disorders seen over a period of one year. The mean age of patients was 28.3 years and most (97.2%) were males. A higher percentage of patients (56.3%) were married. Data regarding educational level and occupation indicate good or above average levels of achievement and status. Explanations for findings are discussed, particularly in relation to the possible role of sociocultural factors.
