Background: Frontotemporal dementia (FTD) is a neurodegenerative disease and is one of the most common causes of dementia in people under 65. There is often a significant diagnostic delay, as FTD can be confused with other psychiatric conditions. A lack of knowledge regardingFTD by health professionals is one possible cause for this diagnostic confusion. Objectives: The aim of this study was to adapt and validate the Frontotemporal Dementia Knowledge Scale (FTDKS) in Spanish. Methods: A translation was done, following cross-cultural adaptationguidelines, which consisted of forward translation, blind back translation, and an analysis by a committee of experts. For the present study, 134 professionals from different health areas responded the Spanish version of the FTDKS. The statistical analysis was performed usingR version 4.0.0 “Arbor day” and the Psych, sjPlot packages. Results: The Spanish version of the FTDKS had good reliability and internal consistency (Cronbach alpha 0.74.). The sample’s mean score was 19.78 (range = 4-32, SD 6.3) out of a maximum of 36 points. Conclusions:The results obtained show that the Spanish version has good psychometric properties. The FTDKS is applicable in our environment and can be a useful tool to evaluate the knowledge of health professionals regarding frontotemporal dementia.
