社區失智友善程度感受量表（民眾版）信效度之檢測

Reliability and Validity Testing of Perceived Community Dementia Friendliness Scale (Public Version)

背景：由於失智症人口的迅速增加，失智症友善社區已成為一項重要的議題。雖然社區失智友善指標已發展，然而，缺少民眾版社區失智友善量表的信度和效度的研究。
目的：檢驗「社區失智友善程度感受量表民眾版」的認知並檢定信、效度。
方法：收集來自台北市兩個行政區200名民眾採方便取樣，該量表包含42題，從社區民眾的角度衡量社區對失智症的認知友善程度。
結果：發現社區失智友善程度感受量表民眾版具有良好的信度，Cronbach's alpha係數為.97。在效度方面，社區失智友善程度感受量表民眾版探索性因素分析「友善的失智症照護服務」(10題)、「友善的社區民眾與環境」(15題)、「友善的交通」(5題)、「友善的商家及機構」(5題)、「友善的醫院服務」(4題)、「友善的社區互動」(3題)。這六個因素解釋變異量為70.72%，符合原始量表之概念。
結論：該量表具有初步的信度和效度，可提供失智友善社區相關服務及政策發展及評值之參考。

Background: Creating dementia-friendly communities has become a critical initiative in response to the rapidly growing dementia population. While key indicators of what constitutes a dementia-friendly community have been established, there remains a gap in understanding the reliability and validity of the community dementia friendliness scale as perceived by the general public.
Purpose: This study aimed to test the reliability and validity of the Perceived Community Dementia Friendliness Scale-General Public Version (PCDF-GP).
Method: A convenience sample of 200 community members was collected from two districts in Taipei. The survey instrument included 42 items designed to assess the perceived level of dementia friendliness within the community, as reported by these community members.
Result: The PCDF-GP demonstrated excellent reliability, with a Cronbach's alpha coefficient of .97. In terms of validity, exploratory factor analysis revealed six distinct factors: ''friendly dementia services'' (10 items), ''friendly community members and environment'' (15 items), ''friendly community'' (5 items), ''friendly shops and organizations'' (5 items), ''friendly hospital'' (4 items), and ''friendly community interactions'' (3 items). These six factors collectively accounted for 70.72% of the variance, affirming the robustness and alignment of the measure with its original construct.
Conclusion: This scale exhibits strong initial reliability and validity and can serve as a valuable reference for the development, evaluation, and enhancement of dementia-friendly community-related services and policies.
