Abstract: | Background/Objective: Social anxiety is a common issue arising in adolescence that can cause significant impairment and have detrimental consequences for development in the absence of treatment. In this study we examined the factor structure and the psychometric properties of a 12-item short form of the Portuguese-Language Social Anxiety Scale for Adolescents (SAS-A-SF). Method: A community adolescent sample (N = 835) and a young offender sample (N = 244) completed the SAS-A, the Basic Empathy Scale and the Reactive-Proactive Aggression Questionnaire. Confirmatory factor analysis, internal consistency, cross gender and cross sample invariance, convergent and discriminant validity of the SAS-A-SF were analyzed. Results: The confirmatory factor analysis revealed that the 3-factor second-order model obtained the best fit.The results provided evidence that the SAS-A-SF is a psychometrically sound instrument that shows measurement invariance across genders and across samples, good reliability and positive correlations with empathy. Conclusions: The Portuguese version of SAS-A-SF is a useful, time-efficient tool for both researchers and practitioners who need to assess social anxiety, a relevant construct in adolescent psychopathology. |
