Construct and concurrent validity of the Dementia Rating Scale-2 Alternate Form.

The Dementia Rating Scale-2: Alternate Form (DRS-2: AF) was developed by Schmidt (2004) for use in serial neuropsychological assessments with the original DRS-2 (Jurica, Leitten, & Mattis, 2001). Results from two preliminary validation studies of the DRS-2: AF are presented here. In Study 1, the DRS-2: AF and four additional neuropsychological measures were administered to 49 healthy, community-dwelling participants without dementia; convergent and discriminant correlational analyses provide evidence for the construct validity of four DRS-2: AF subscales (Attention, Initiation/ Perseveration, Conceptualization, Memory).
