Versión abreviada en español del test de denominación de Boston: su utilidad en el diagnóstico diferencial de la enfermedad de Alzheimer

A short-form version of the Boston Naming Test for language screening in dementia in a bilingual rural community in Galicia (Spain)

“…The distribution of sensitivity and specificity showed that in our population many items in the BNT 60-item versions are easily recognized by most participants irrespectively of diagnosis, whereas others are never recognized either by cases or by controls. This finding encourages the development of specific shortened versions of the BNT, a similar rationale to that followed by Calero et al (2002) and Serrano et al (2001) in Andalusia and Argentina, respectively.…”

“…The study objectives were therefore to design a shortened version for a rural population of low educational level in Galicia (Spain) and to compare its performance with other short versions devised for different Spanish-speaking populations in Argentina (Serrano et al, 2001) and Andalusia (Spain) (Calero et al, 2002).…”

“…Moreover, cultural and lexical characteristics are specific for each region or for specific groups like illiterates, bilinguals, and people living in rural environments or populations with high rates of migration. Following this rationale, Serrano et al (2001) developed a shortened version (12 items) adapted to Argentina by choosing items that specifically distinguished patients with dementia from those without dementia in their target area. Later, Calero et al (2002) tested the shortened version proposed by Mack et al (1992) in southern Spain with reasonable success.…”

“…Third, it offered the highest degree of flexibility for STAWG in the selection of items that would be applicable for the use with older Spanish-speaking ADC participants from different nationalities and backgrounds. The latter is important, as most of the studies that have used the official Spanish BNT versions have been based on the samples from Spain and Argentina 50–53. It is noted that existing agreements between NACC and the BNT publishing companies required that the order of presentation of the items in the resulting UDS Spanish BNT version follow the same relative order as that in the official 1996 Spanish BNT version.…”

“…Special consideration would be given to the 12 items of the 1996 BNT Spanish version that were shown by Serrano et al53 to have high sensitivity and specificity in the identification of Spanish-speaking elderly AD patients versus those who were cognitively normal and that, in addition, were not biased by education.…”
