Factor Structure, Reliability and Validity of the European Portuguese Version of the Revised Childhood Anxiety Sensitivity index (Casi-R) in a Clinical Sample of School-Aged Children

The present study explored the factor structure, reliability and convergent validity of the Portuguese version of the Childhood Anxiety Sensitivity Index – Revised (PT-CASI-R) in a clinical sample of school-aged children. A clinical sample of 153 children with emotional disorder symptomatology (i.e., anxiety or depressive disorder; 6-13 years) completed the CASI-R and the Revised Child Anxiety and Depression Scale (RCADS). A confirmatory factor analysis was performed and the psychometric properties of the CASI-R were assessed. The PT-CASI-R revealed good internal consistency, with a four-factor hierarchical structure. Moderate and strong correlations were found between the CASI-R and RCADS subscales, specifically the “panic disorder” RCADS subscale. Our findings suggest that the PT-CASI-R is a psychometrically valid measure for assessing anxiety sensitivity in Portuguese children with clinical emotional symptoms, between 6 and 13 years old
