One factor that has been examined as a predictor in the development of anxiety in children is anxiety sensitivity (AS), which is the fear of anxiety symptoms and belief that negative outcomes will result from them (Reiss, 1991). AS has been significantly associated with anxiety—especially panic disorder—in both adults and children (e.g., Rachman, 1998; Lau, Calamari, & Waraczynski, 1996).
AS has been most commonly assessed to date using the Childhood Anxiety Sensitivity Index (CASI; Silverman., Fleisig, Rabian, & Peterson, 1991). However, a revised and expanded version of the CASI, the CASI-R, was developed by Muris (2002) to more comprehensively asses the lower-order facets comprising the AS construct.
Initial psychometric analyses using the CASI-R yielded excellent internal consistency reliability estimates for all four subscales (α=.81-.88; Muris, 2002). While a replication study assessing a French translation of the CASI-R found estimates that were much lower than that found originally (α=.62-.75), they were still considered adequate (Stassart, Hansez, Delvaus, Depauw, & Etienne, 2013). Both analyses, however, examined children aged 12 and older. The purpose of this study was to examine the psychometric properties of the CASI-R—including internal consistency reliability of its subscales as well as convergent and discriminant validity—in a novel sample of elementary and middle school-aged children.
Participants in the preliminary analysis included 73 children, aged 8 to 14 (M=11.04 years, SD=1.82)—who were recruited from private schools in a Midwestern city. Children completed self-report measures of anxiety sensitivity (the CASI and the CASI-R), as well as anxiety and depressive symptoms (the RCADS), as part of a larger study. Data collection is ongoing.
