Computerized Assessment of Response Bias
The Computerized Assessment of Response Bias (CARB) is a computer-based assessment tool for evaluating effort. The test is one of many tests characterized as symptom validity tests (SVT), measures of response bias, tests used to assess possible malingering or poor effort, and tests of exaggeration of deficit. The test is a computerized version of the digit recognition paradigm using a forced choice format, akin to the procedure described by Hiscock and Hiscock (1989) and Binder (1990). Frequently, statistical determination of below chance performance (based on the binomial theorem) has been used with tests such as these. However, CARB has been described as an easy test to perform, resulting in the ability to detect inadequate effort using above chance cut-off scores (Millis 2008, p. 896). The test has been studied with a wide variety of populations, including head injury, chronic fatigue syndrome, musculoskeletal injuries, pain disorders, and psychiatric or...
