Abstract
The purpose of this study was to analyze the component structure and reliability of the Liebowitz Social Anxiety Scale for Children and Adolescents, self-report version (LSAS-CA-SR), in a Spanish community population. The sample was made up of 422 students from elementary and high schools, aged between 10 and 17 years. Exploratory factor analysis isolated one component for the Anxiety subscale and one component for the Avoidance subscale. Medium-strong associations were found between the total score and subscale scores. LSAS-CA-SR scores had stronger associations with instruments of social anxiety. Internal consistency for the Fear subscale was .91, and for the Avoidance subscale, it was .89. Gender and age effects were assessed for LSAS-CA-SR scores. Effect sizes for age and gender and interaction of age and gender were very low on both the Fear and the Avoidance subscales. There were significant differences between female and male means on the Fear subscale. The findings suggest that the LSAS-CA-SR is reliable and valid.
