Translation and Validation of the Chinese Version of the Brief Adolescent Attitudes Towards Dementia Scale (Brief AADS-C): A Psychometric Study.

Abstract

BackgroundA validated instrument for assessing adolescent attitudes toward dementia in Chinese-speaking communities is currently lacking. This study aims to translate the Brief-AADS into Chinese and examine the psychometric properties of the Brief AADS-C.MethodsThe methodological study employed a cross-sectional design with 2 phases. Data was collected in Macao and Shenzhen, China.ResultsThe scale demonstrated excellent content validity(S-CVI = 0.99) and good internal consistency (Cronbach's α = 0.814). Test-retest reliability was acceptable (ICC = 0.647). EFA identified a three-factor solution "Perceptions", "Acceptance", and "Engagement" with 11items-accounting for 56.07% of the variance. CFA supported this 3-factor structure with acceptable goodness of fit indices (χ²/df = 3.076, GFI = 0.937, SRMR = 0.0579, RMSEA = 0.077). All factor loadings of the items ranged from 0. 33to 0.82, indicating strong item-factor relationships.ConclusionsThe Brief AADS-C is reliable and valid for assessing adolescent attitudes toward dementia in Chinese-speaking regions.
