The Community Integration Questionnaire CIQ) was developed by Barry Willer Ph.D. and a group of professionals and consumers to provide a measure of community integration after traumatic brain injury that could be used in the TBI Model Systems program, funded by the National Institute on Disability and Rehabilitation Research (NIDRR). They used the following design criteria: brevity; suitable for use in an in-person or telephone interview, conducted with the person with TBI him/herself (preferably), or with a proxy; focus on behaviors rather than feeling states; no biases resulting from age, gender or socioeconomic status; sensitive to a wide variety of living situations; and value neutral.
