Social phobia is the most prevalent anxiety disorder. It is accompanied by a deterioration of the quality of life and social adaptation. This has further impact that this disorder begins at a young age at the time where the topic has not yet acquired a stable socio-professional status.

The aim of our study was to assess the sounding of the social phobia among a population of 200 students.

It was a cross-sectional study, focusing on a group of 200 students from 5 universities in Sfax city, Tunisia.

We used:

1. - The Liebowitz Social Anxiety Scale for screening the social phobia,

2. - The Sheehan scale for the evaluation of the sounding on the social, professional and family life.

Thirty three per cent of this population presented a social phobia.

According to Sheehan scale, the disturbance in school, social and family life was mild to moderate (schooling: 3. 29; social: 2.95; family: 2.62).

Discussion and conclusion: Our study showed that the impact of the social phobia is lightweight at the family and social level but more important in the area of schooling. This suggests the necessity for screening and treatment of social phobia among students for a better socio-family insertion and especially for better academic achievement.
