The university transition life is the most frequent source of problems. These problems results from stress academic and family relationship dysfunction. These stress factors can pose a risk in student's mental and physical health.

However, stress is the result of a transaction between the person and the environment.

Of this work is to validate the specific scale of perceived stress among Tunisian students.

To evaluate the perceived stress among students, we used the specific scale of perceived stress (Boujut E, Bruchon-Schweitzer M, 2003). This scale was constructed and validated on French students.

The scale is as a self-administered questionnaire consisting of 25 items.

The validation was made on a representative sample of university students (n = 500) randomly selected.

The main properties studied were: acceptability, reliability (Pearson’s coefficient ‘r’), face validity and content validity (Cronbach's alpha).

The acceptability of the questionnaire was good, less than 10% of students were unable or unwilling to complete the questionnaire. The Pearson coefficient showed good reliability for this scale r = 0.98, p < 0.05. The Cronbach's alpha was acceptable for all items of the scale α = 0.81.

The specific scale of perceived stress is valid among Tunisian students. It is now available for clinicians to measure the level of perceived stress among students.
