知識、態度與社區意識對協助失智者意願之關係：以台北市為例

Relationships among dementia knowledge, attitudes, sense of community, and helping intentions: a case study of Taipei City

目標：隨著全球高齡化加劇，失智症已成為重要的公共衛生議題。台灣邁向超高齡社會，社區中失智症患者人數日增，社會對失智症的識能與態度對失智友善環境的建構至關重要。然而，相關研究仍有限。本研究調查台北市18歲以上居民的失智症知識、態度、社區意識與對失智症患者的助人意願的關係，並探討態度的中介作用角色與社區意識的調節效應。方法：研究採橫斷式設計，以網路問卷收集3,259份資料，涵蓋台北市12區。問卷內容包括：失智症知識量表（DKAS-s）、失智症態度量表（DAS-6）、社區意識量表（SCI-2）、對失智症患者的助人意願以及人口學資料等。結果：結果顯示，失智症知識、態度、社區意識與助人行為意圖彼此有正相關。態度在知識與助人行為意圖間具有完全中介作用；社區意識則一方面提升助人行為意圖，另一方面也小幅度減弱態度對助人行為意圖的影響。結論：提升民眾的失智症知識，以及與失智症者相處時的舒適感和正向認知，皆有助於促進助人意願，營造社區支持氛圍亦同樣關鍵。政策應強化教育與社區營造，推動失智友善社會的發展。

Objectives: With the acceleration of global population aging, dementia has become a major public health concern. Taiwan is rapidly transitioning into a super-aged society, with a growing number of individuals with dementia living in community settings. The public’s dementia literacy and attitudes play a critical role in fostering dementia-friendly environments. However, relevant empirical studies remain limited. Accordingly, using a sample of Taipei residents aged 18 years or older, this study investigated the relationships among dementia knowledge, attitudes, sense of community, and intentions to engage in helping behaviors toward individuals with dementia. Furthermore, it examined the mediating role of attitudes and the moderating effect of community awareness. Methods: A cross-sectional study was conducted using an online survey, which yielded 3,259 valid responses from residents of 12 Taipei districts. The questionnaire comprised the Dementia Knowledge Assessment Scale–Simplified, the Dementia Attitudes Scale–6, the Sense of Community Index 2, measures of prosocial behavioral intentions toward individuals with dementia, and questions on demographic variables. Results: Dementia knowledge, attitudes, sense of community, and intentions to help were all positively correlated. Attitudes fully mediated the relationship between knowledge and behavioral intentions. A sense of community enhanced helping intentions and slightly weakened the effect of attitudes on behavioral intentions. Conclusions: Enhancing public knowledge of dementia and strengthening individuals’comfort and capacity to adopt a positive attitude when interacting with people with dementia are both crucial for promoting dementia-friendly behaviors. Additionally, fostering a supportive community environment is crucial. To promote a more dementia-inclusive society, policymakers should prioritize public education and community engagement.
