Stanine and percentile scores.

     The CADL-2 assesses the functional communication skills of adults with neurogenic communication disorders. It has 50 test items in seven areas:

	Reading, Writing, or Using Numbers
	Social Interactions
	Divergent Communication
	Contextual Communication
	Nonverbal Communication
	Sequential Relationships
	Humor/Metaphor/Absurdity

     Original CADL-2 items that required role playing, use of an audiocassette for identification of environmental sounds, and certain props were eliminated to ease test administration and reduce total test time.

     The updated norming sample included 175 adults with neurogenic communication disorders resulting primarily from left- or right-hemisphere stroke or traumatic brain injury. Level of care spanned the full continuum of acute care to subacute, long-term, home, and outpatient care. The sample was stratified to approximate the 1997 Statistical Abstract of the United States (U.S. Bureau of the Census).

     Reliability coefficients were: .93 coefficient alpha, .85 test-retest, and .99 interscorer. The CADL-2 also was found to be valid as a functional communication test for adult neurogenic populations.
