The Columbia Impairment Scale (CIS) is a 13-item scale that asks about possible child behavioral problems and can be used as a global measure of impairment. The scale asks about 4 major areas of functioning: interpersonal relationships, broad psychopathological domains, functioning in schoolwork, and use of leisure time. Beginning in 2018 the CIS is fielded every other year and will only be collected in odd years. See our user note for more details on this and other changes that occurred in 2018.

Some questions on the CIS are coded to "Asked, but inapplicable" (6) when the question did not apply for the child (e.g., how much of a problem the child has getting along with their siblings for children with no siblings).

To calculate a summary score for the CIS, sum responses to all items, excluding items where the response was "Asked, but inapplicable" (6) or an unknown response (codes 7, 8, and 9). Higher scores indicate greater impairment.
