Introduction: The main purpose of this research is develop the Turkish version of the BNT long form (consist of 60 items) [BNT-60 (TR)] and to determine the normative data for Turkish healthy geriatric population. BNT is a neuropsychological test which was widely used to measure naming disorders associated with a variety of neuropathological events. This research consists of two stages. In the stage of pilot study, adaptation of test was completed and BNT-60 (TR) version was developed; and in the stage of normative study, normative data was collected and norm determination was completed. Methods: Ninety healthy and volunteer elderly were participated in pilot study and 317 were in normative study. Three screening tests called Montreal Cognitive Assessment (MOCA), Functional Activities Questionnaire (FAQ) and Geriatric Depression Scale (GDS) were administered for participant selection. BNT-60 (TR) was applied to participants who meet the inclusion criteria. Results: According to 5 (age) x 2 (gender) x 3 (education) factorial ANOVA results, main effects of age and education level on BNT-60 (TR) total score were found statistically significant. Then according to MANOVA results, main effects of age and education level on BNT-60 (TR) sub-scores were found statistically significant. On the other hand, main effect of gender was not significant on BNT-60 (TR) scores. The age and BNT-60 (TR) total score were negatively correlated. This results consistent with other normative studies of BNT in the literature. Conclusion: Finally, BNT-60 (TR) is adopted for Turkish culture, determined normative data and a test which is evaluating naming ability of the older adults was put into use.
