The SCCAN is designed to assess a broad range of neurological patients for cognitive-communicative impairment and functional ability, to determine the severity of impairment, and to guide planning of treatment. It is appropriate for use by speech-language pathologists, neuropsychologists, psychologists, and other rehabilitation professionals, especially in rehabilitation hospitals, clinics, and skilled nursing facilities. The SCCAN assesses daily activities that adults would be expected to perform for independent living. There are eight scales:
Basals and ceilings are built into the SCCAN to decrease examinee fatigue and increase efficiency of test administration.
The SCCAN was normed on 256 adults between 18 and 91 years old, from 11 states. Statistical analysis found strong evidence of content, temporal, and interscorer reliability, as well as solid evidence of content-description, criterion-prediction, and construct validity. Samples were collected to evaluate the use of the SCCAN with patients who had left- and right-hemisphere stroke, Alzheimers disease, and traumatic brain injury.
Administration and Scoring
The SCCAN takes 30-45 minutes to administer. It yields a standard score, percentile rank, and percentage score. Scores can be help make a differential diagnosis by comparing the examinees performance with three profiles particular to certain types of brain injury.
