The self-report Version of the LSAS-CA: Psychometric Properties of the French Version in a non-clinical adolescent sample

The Liebowitz Social Anxiety Scale (LSAS) is one of the most popular measures of social anxiety in adults. The LSAS has been adapted for clinical assessment of children and adolescents (LSAS-CA). The psychometric properties of the self-report version of the LSAS-CA (LSAS-CA-SR) have been investigated in a Spanish population. However, no study to date has adapted and validated this scale in French. The purpose of this study was to develop a French version of the LSAS-CA-SR and to assess its score reliability and structural validity in a French-speaking community sample. The sample was made up of 1,343 teenagers from secondary schools, aged between 14 and 18 years. Confirmatory factor analyses established the structural validity of the French version of the LSAS-CA-SR and good psychometric properties, including reliable internal consistency, were observed.
