Psychometric Properties of the Family Stigma in Alzheimer's Disease Scale in Greek Professional Caregivers.

BACKGROUND AND PURPOSES: The present study was undertaken in order to evaluate the validity and reliability of the Family Stigma in Alzheimer's Disease Scale (FS-ADS) in the Greek population. METHODS: The Greek version of the FS-ADS as well as the Maslach Burnout Inventory (MBI) was administered to 171 healthcare professional caring for people with dementia. Exploratory factor analysis was performed to examine the factor structure of the FS-ADS. Test-retest reliability was measured by administration of the FS-ADS in 20 individuals. RESULTS: Principal component analysis revealed 5, 8 and 3 factors (subscales) for each dimension of the original questionnaire, respectively, similar to other previously reported results in the literature. The overall Cronbach's α was .899, yielding a high internal consistency. Test-retest reliability was very high (r = 0.903, p < .001). Statistically significant relationships were found between most of the FS-ADS dimensions and Maslach subscales. CONCLUSION: The findings favor the use of FS-ADS in nurses and professional caregivers in general, for measuring stigma in dementia in Greece.
