Objective:
Despite recent advances in cross-cultural neuropsychological test development, suitable tests for cross-linguistic assessment of language functions are not widely available. The aims of this study were to develop and validate a brief naming test, the Copenhagen Cross-Linguistic Naming Test (C-CLNT), for the assessment of culturally, linguistically, and educationally diverse older adult populations in Europe.
Method:
The C-CLNT was based on a set of standardized color drawings. Items for the C-CLNT were selected by considering name agreement and frequency across five European and two non-European languages. Ambiguities in some of the selected items and scoring criteria were resolved after pilot testing in 10 memory clinic patients. The final 30-item C-CLNT was validated by verifying its psychometric properties in 24 controls and 162 diverse memory clinic patients with affective disorder, mild cognitive impairment, and with dementia.
Results:
The C-CLNT had acceptable scale reliability (coefficient alpha = .67) and good construct validity, with moderate to strong correlations with traditional language tests (r = .42– .75). Diagnostic accuracy for dementia was good and significantly better than that of the Boston Naming Test (areas under the curve of .80 vs .64, p < .001), but was poor for mild cognitive impairment. Only 3% of the variance in C-CLNT test scores was explained by immigrant background, while 6% was explained by age and years of education. In comparison, these proportions were 34 and 22% for the BNT.
Conclusions:
The C-CLNT has promising clinical utility for cross-linguistic assessment of naming impairment in culturally, linguistically, and educationally diverse older adults.
