The Spanish version of the Frontotemporal Dementia Knowledge Scale (FTDKS) is a reliable tool for assessing health professional knowledge of FTD. This validated scale helps improve diagnostic accuracy for this common dementia in younger individuals.
Area of Science:
- Neurology
- Psychiatry
- Medical Education
Background:
- Frontotemporal dementia (FTD) is a leading cause of dementia in individuals under 65.
- Diagnostic delays in FTD are common due to confusion with psychiatric conditions.
- Limited health professional knowledge contributes to FTD misdiagnosis.
Purpose of the Study:
- To adapt and validate the Frontotemporal Dementia Knowledge Scale (FTDKS) for use in Spanish.
- To provide a reliable instrument for assessing FTD knowledge among Spanish-speaking healthcare providers.
Main Methods:
- Cross-cultural adaptation using forward and backward translation and expert review.
- Administration of the Spanish FTDKS to 134 healthcare professionals.
- Statistical analysis of psychometric properties using R and relevant packages.
Main Results:
- The Spanish FTDKS demonstrated good reliability and internal consistency (Cronbach's alpha = 0.74).
- The mean score on the Spanish FTDKS was 19.78 out of 36.
- The scale showed good psychometric properties in the studied population.
Conclusions:
- The Spanish version of the FTDKS is a psychometrically sound instrument.
- The FTDKS is suitable for evaluating frontotemporal dementia knowledge in Spanish-speaking healthcare settings.
- This validated scale can aid in identifying knowledge gaps and improving FTD care.
