Abstract

Fear of Alzheimer's Disease Scale (FADS, French, Floyd, Wilkins i Osato, 2011) is the first measure that addresses anticipatory dementia, or, more precisely, fear of Alzheimer's disease. It is intended for the general population of older adults and it considers different aspects of fear of dementia (cognitive, emotional and physical dimension). Original study showed that the scale is composed of 3 stable interrelated factors labeled General Fear, CatastrophicAttitude and Physical Symptoms. The aim of the study was to determine factor structure and test validity and reliability of the scales in acroatian sample of older adults (N=116) for the first time. Our results indicated a low expressed fear ofAlzheimer's disease in the current sample. Principal components analysis with oblimin rotation extracted 3 stable factors that correspondedby contentto the ones previously determined. Internal consistency proved to be high for the entire scale and also for each of the 3 extracted factors, as well as construct validity estimated through correlation with The State-Trait Anxiety Inventory (STAI) scores which was also found to be high, with higher correlation with trait anxiety subscale. Advantages and limitations of the current research, as well as guidelines for further research work are also presented
