The Community Reintegration of Injured Service Members (CRIS) measure consists of
three scales measuring extent of, perceived limitations in, and satisfaction with
community reintegration. Length of the CRIS may be a barrier to its widespread
use. Using item response theory (IRT) and computer-adaptive test (CAT)
methodologies, this study developed and evaluated a briefer community
reintegration measure called the CRIS-CAT. Large item banks for each CRIS scale
were constructed. A convenience sample of 517 Veterans responded to all items.
Exploratory and confirmatory factor analyses (CFAs) were used to identify the
dimensionality within each domain, and IRT methods were used to calibrate items.
Accuracy and precision of CATs of different lengths were compared with the
full-item bank, and data were examined for differential item functioning (DIF).
CFAs supported unidimensionality of scales. Acceptable item fit statistics were
found for final models. Accuracy of 10-, 15-, 20-, and variable-item CATs for all
three scales was 0.88 or above. CAT precision increased with number of items
administered and decreased at the upper ranges of each scale. Three items
exhibited moderate DIF by sex. The CRIS-CAT demonstrated promising measurement
properties and is recommended for use in community reintegration assessment.
