Resumen
- Background and Objectives The number of people living with dementia is increasing globally, particularly in middle-income countries like Turkey. To reduce risk of dementia, the implementation of lifestyle changes targeting modifiable risk factors are important. This study aimed to translate and validate the Turkish version of the Motivation to Change Lifestyle for Dementia Risk Reduction (T-MOCHAD-10).
  
  Methods Cross-sectional psychometric study design was used. After translation and back translation, we assessed face and content validity. For construct validation and reliability assessment, we conducted a survey with 601 individuals aged 40 and above using a socio-demographic form and the T-MOCHAD-10. We used Exploratory Principal Axis Factoring with Oblimin rotation to explore the factor structure. We then confirmed the factor structure using fit indices. Reliability was established using test-re-test, Cronbach's alpha coefficient, item-total and item-subdimensions correlations, ceiling and floor effects, and the Hotelling's T-squared test.
  
  Results The T-MOCHAD-10 showed adequate face and content validity (Kendall W=0.09, p=0.60). As in the original scale, a two-factor solution was obtained. All fit indices were ≥0.95, and RMSEA was 0.06. A Cronbach's alpha of 0.79 was obtained and no significant differences were found between test and re-test measures (p>0.05). We found no evidence of ceiling or floor effects, nor response bias (Hotelling's T-squared=4683.80, p<0.001).
  
  Conclusion T-MOCHAD-10 is a short measurement tool which provides valid and reliable scores concerning the motivation to change lifestyle for reducing dementia risk among Turkish individuals aged 40 and over.
