A measure of anxiety symptoms among children.

The Spence Children's Anxiety Scale (SCAS) is a child self-report measure designed to evaluate symptoms relating to separation anxiety, social phobia, obsessive-compulsive disorder, panic-agoraphobia, generalized anxiety and fears of physical injury. The results of confirmatory and exploratory factor analyses supported six factors consistent with the hypothesized diagnostic categories. There was support also for a model in which the 1st-order factors loaded significantly on a single 2nd-order factor of anxiety in general. The internal consistency of the total score and subscales was high and 6 month test-retest reliability was acceptable. The SCAS correlated strongly with a frequently used child self-report measure of anxiety. Comparisons between clinically anxious and control children showed significant differences in total SCAS scores, with subscale scores reflecting the type of presenting anxiety disorder of the clinical samples.
