Abstract

This study tested the utility of assessing anxiety sensitivity (AS) in children by investigating the long term stability and psychometric properties of a Catalan version of the Childhood Anxiety Childhood Anxiety Sensitivity Index (CASI, Silverman et al., 1991, Journal of Clinical Child Psychology, 20, 162-168) in a sample of 291 elementary-school children. The Catalan CASI demonstrated acceptable internal consistency and convergent validity estimates, similar to previous research with the English version. The measure also showed incremental validity in relation to other measures of anxiety and test-retest analyses suggested considerable three month and one-year stability in children's level of AS. Finally, a principal component analysis of the Catalan CASI yielded five lower-order factors grouped on a unique higher-order factor. The similarity of the findings to previous research on the CASI and on AS in English speaking children and adults is discussed and some suggestions for future investigations are presented.
