Abstract

Objective: The objectives of the present study were to adapt the Liebowitz Social Anxiety Scale from the clinician administered to the self-report version (LSAS-SR) and to perform the initial psychometric studies concerning internal consistency and item analysis.

Methods: The phase of adaptation was performed by two specialists in the Mental Health area and the face validity was tested by a group of 30 university students. As part of the psychometric study of the LSAS-SR, the internal consistency was assessed and the items were analyzed by applying the scale to 682 university students.

Results: The LSAS-SR proved to be easy to understand by the group studied, with no need to make any changes in the instructions for application. The scale showed adequate internal consistency (α = 0.96) as well as an acceptable correlation between items and total score (0.38-0.72).

Conclusions: The initial psychometric studies of the LSAS-SR presented adequate indicators, stimulating the continuation of studies involving the validation and reliability of the scale not only when applied to a sample of the general population, but also when applied to clinical groups.
