Scoring / Benchmarking
The statements are scored using a 4-point scoring system. The questionnaire consists of 15 statements, to each of which a parent or caregiver assigns a number between 1 and 4 that correspond to the following: 1 = Very much like your own home; 2 = Somewhat like your own home; 3 = A little bit like your own home; 4 = Not at all like your own home. A single score is derived from the CHAOS questionnaire by summing the responses for the 15 items. A higher score represents characteristics of a more chaotic, disorganized, and hurried home. The higher the score, the more chaotic a home is considered to be.
