Abstract
Introduction: The Boston Naming Test (Kaplan, Goodglass & Weintraub, 1983, 2001) is a test of visual confrontation naming that evaluates the ability of lexical access. The influence of socio-demographic variables is significant in this task and it is important to establish its characteristics in each population.
Objective: To analyze the psychometric characteristics of BNT in a Colombian population of controls, analyze error types and raise cutoff points according to sociodemographic variables.
Materials and methods: Performance of 252 participants (74 men, 178 women, 123 <65, 129> 65, at three levels of schooling (60 low, 64 medium, 128 high). The study is comparative-descriptive study. Frequency of each of error types according to age groups and schooling was analyzed. Analysis was performed from the Classic Theory of Tests (TCT), and cutoffs were derived.
Results: We found that in people over 65 years with low education levels, the more frequent error types are visual and nonresponse, while in people under 65 and education level, semantic and visual-semantic errors predominate. An array of stimuli in increasing difficulty for the Colombian sample is presented and the particular performance of the studied Colombian controls are identified.
Conclusion: The importance of the test in the Colombian context, its usefulness, and a highlight of some clinical criteria to differentiate normal from pathological aging are discussed.
