Psychometric characteristics of the Community Integration Questionnaire (CIQ) were replicated and extended. Retrospective CIQs assessing premorbid functioning were completed at inpatient admission for 461 patients with traumatic brain injury (TBI) or disabilities resulting from other injuries. Data were collected at follow-up from 217 persons. The total score was normally distributed, with premorbid scores showing a slight negative skew. Significant mean differences for premorbid versus follow-up samples were evident for the total score and all three subscales, except TBI home integration. Age and gender had minimal effects on total and subscale scores. Overall, results supported the utility of the CIQ as a measure of handicap following TBI. Problems in the distribution of the productivity subscale suggested that it should not be used independently of the total score. Findings also suggested that retrospective assessment may be a useful method for collecting comparative data and that the CIQ can be used to measure integration in populations other than TBI.
