Psychometric Properties of Forman Alzheimer’s Disease Scale (FADS)

The purpose to develop psychometric properties of the Forman Alzheimer's disease scale (FADS) is to screen-out patients with dementia in Pakistan.Through non-probability purposive sampling technique, a sample of Alzheimer's patients (N = 320) with age range of 47-87 years (M = 66.10;SD = 6.21) was taken in this study.The patients, who had dementia other than Alzheimer's disease and vascular type dementia, were excluded from the study.Information from the primary caregivers of the patients was obtained through a demographic sheet and a questionnaire.Data analysis was done by using SPSS software version 26.The factor structure of the scale was explored by using exploratory factor analysis.Preliminary analysis indicated two factors for the scale that is psychometrically valid to use with patients with dementia.The two factors are named as Cognitive deficits and activities in daily living and Neuropsychiatric symptoms.Pearson Product Moment Correlation was used to measure the correlation of age and Forman Alzheimer's disease scale.Results revealed (r = .28,p < .001)positive correlation of disease with age.
