The aim of this study was to test whether a Czech version of the Trail Making Test (TMT) yields normative data scores that approximate those based on English (North American) and Spanish normative samples. In all samples, TMT Parts A and B were administered according to the guidelines.
Completion times for healthy adults from the Czech Republic (n = 422, Bezdicek et al., 2012), the United States (n = 325, Schretlen et al., 2008) and Spain (n = 348, Ojeda, Peña, unpublished data), stratified for age and education, were compared. Czechs took less time to complete TMT-B than English and Spaniards in 70-74 and older age groups (all ps < .01) even after covarying for education, although the amount of variance explained by language (i.e.
Czech/Spanish/English) was small (0.3%; p < .001). In addition, TMT-A performance was significantly faster in Czech and English (North American) populations than in Spaniards.
In conclusion, this demonstrates a lack of sociocultural equivalence on TMT-A and B, suggesting the need for adjustment of available TMT norms for use in different cultures.
