[Shortened version of the Barcelona test (III): criterion validity with the ADAS-Cog].
The aim of this study was to assess the criterion validity of a global score of an abbreviated version of the Barcelona Test (BTA), normalized for age and education, as a clinical neuropsychometric test for the assessment of cognitive impairment. This study made a correlational analysis between test scores of the BTA and scores of the cognitive part of the Alzheimer's Disease Assessment Scale (ADAS-Cog) adjusted for age and education. It was made in a University Hospital (Dementia Unit). A group of 172 subjects (74 male, 98 female) was distributed according the Global Deterioration Stages (GDS) from 1 to 6. GDS-1 (normal controls), n = 60; GDS-2 (subjective complaints), n = 27; GDS-3, n = 21, GDS-4, n = 22; GDS-5, n = 16; GDS 6, n = 26. All dementia patients fulfilled the NINCDS/ADRDA criteria. BTA global scores correlated significantly with adjusted scores on the ADAS-Cog (r = 0.872, r2 = 0.761), p < 0.0001. The BTA has a criterion validity as a clinical neuropsychometric test for the study of cognitive impairment.
