Comparison of alternatives to multidimensional scoring in the assessment of language comprehension in aphasia.
OBJECTIVE
Multidimensional scoring methods yield valuable information about communication abilities. However, issues of training demands for valid and reliable scoring, especially in current service delivery contexts, may preclude common usage. Alternatives to multidimensional scoring were investigated in a sample of adults with aphasia.


METHODS
One alternative method involved modified multidimensional scoring; the others incorporated correct/incorrect scoring. The scores for the 3 alternative methods were derived from the scores obtained using the traditional multidimensional method. Revised Token Test scores obtained using the traditional multidimensional method were collected from 10 participants with aphasia. These scores were manipulated to yield 3 additional sets of scores corresponding to the alternative methods.


RESULTS
There were no significant differences between the traditional multidimensional method and 1 of the correct/incorrect methods. Significant differences were found between traditional multidimensional scoring and each of the other 2 methods.


CONCLUSIONS
The study findings suggest that simpler scoring systems might yield similar data to traditional multidimensional scoring. If simpler alternative methods yield similar results, using alternative scoring methods with published tests based on multidimensional scoring will help expand their use in everyday clinical practice.
