The study of anthropomorphism in adults has received considerable interest with the development of the Individual Differences in Anthropomorphism Questionnaire (IDAQ; Waytz, Cacioppo, & Epley, 2010). Anthropomorphism in children--its development, correlates, and consequences--is also of significant interest, yet a comparable measure does not exist. To fill this gap, we developed the IDAQ-Child Form (IDAQ-CF) and report on 2 studies. In Study 1A, adults (N = 304) were administered the IDAQ and IDAQ-CF to directly assess comparability between the measures. In Study 1B, an additional 350 adults were administered the IDAQ-CF to confirm that the new measure had the same underlying structure as the original IDAQ when the measures were not administered together. In Study 2, children (N = 90) in 3 age groups--5, 7, and 9 years old--were administered the IDAQ-CF and an Attribution Interview, which probed their conceptions of a robot and puppet. Results indicated the IDAQ-CF a) is comparable to the original IDAQ in adult (Studies 1A and 1B) and child (Study 2) samples, and b) predicts children's tendency to attribute animate characteristics to inanimate entities (Study 2). This research provides strong evidence that the IDAQ-CF is an effective adaptation of the original IDAQ for use with children.
