The Confusion, Hubbub, and Order Scale (CHAOS; Dumas et al., 2005) is a 15-item measure of environmental confusion; it asks caregivers to designate whether specific descriptions about the organization of the home are typical of the family or not (true or false). Items are derived from a list of factors typically found in chaotic homes, with 8 of the 15 items comprising one factor for chaos in the home. The internal consistency for the chaotic home environment score was .74.
