Abstract: Objective: To identify internal structure validity evidence of a dysphagia screening questionnaire for caregivers of older adults with Alzheimer’s disease dementia and/or vascular dementia. Methods: The 24-question Dysphagia Screening in Older Adults with Dementia − Caregiver Questionnaire (RaDIDQC) was administered by interviewing 170 caregivers of older people with dementia, selected by convenience at the Outpatient Reference Center for Older People. Exploratory Factor Analysis (EFA) was used to assess the internal structure validity of the questionnaire, and Cronbach’s alpha was used to analyze reliability. Questions with factor loadings lower than 0.45 in magnitude were removed from the final questionnaire. Multivariate multiple linear regression was used to assess the percentage of variance explained by the remaining questions. Results: Kayser-Meyer-Olkin (KMO) and Bartlett’s tests suggested that the questionnaire was adequate for EFA. Principal Component Analysis (PCA) suggested that 12 components captured at least 75 % of the total variance. The corresponding 12-factor EFA model showed a statistically significant fit, and 15 out of the 24 questions had factor loadings greater than 0.45. Cronbach’s alpha was 0.74 for the 15 questions, which explained 71 % of the total variance in the complete dataset. The questionnaire has adequate internal structure validity and good reliability. Based on EFA, RaDID-QC decreased from 24 to 15 questions. Other internal validity and reliability parameters will be obtained by administering the questionnaire to larger target populations. Conclusion: The RaDID-QC applied to caregivers of older adults with dementia due to Alzheimer’s disease and/or vascular dementia produced valid and reliable responses to screen dysphagia signs and symptom.
