Content Validity of the Visual Similes Test II

Abstract

This study examined the content validity of the Visual Similes Test II, designed to measure affective and cognitive arousal in individuals 5 to 21 years of age. The 54 participants were asked to rate the affective and cognitive content of un-occluded stimuli from the Visual Similes Test II. The participants, whose mean age was 27.0 yr. ( SD = 8.6), included 1 (2%) man and 53 (98%) women who were enrolled in undergraduate and graduate special education courses. Paired-sample t tests comparing the affective and cognitive ratings for each item were significant for 53 of the 55 stimuli. The mean effect size (Cohen d) was 1.49 (range=.08 to 1.9).
