Objective: This study evaluated the psychometric property of the Chinese version of the 12-item Expectations Regarding Aging Scale (C-ERA) in China. Method: The C-ERA was finalized after forward-translation, back translation, synthesis, pilot testing, and expert panel. A convenient sample of 458 community dwellers was used. The reliability and validity were investigated using content validity, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), Split-half Reliability, Item Analysis, Convergent Validity and discriminant validity. Results: The content validity index at item level was 0.831. The overall Cronbach's coefficient of the scale is 0.953 and split-half reliability is 0.904 and 0.933 respectively. Three factors were extracted by EFA and the cumulative variance contribution rate is 84.24%, demonstrating an acceptable model fit confirmed by CFA. Convergent validity and discriminant validity were acceptable except physical health dimension. Conclusion: The psychometric properties of the CERA were confirmed and provided evidence for expectations regarding aging assessment.

目的：引進簡版老化期望量表（Expectations Regarding Aging Scale，ERA）並對其中文版進行心理學測量標準評價。方法：依據健康照護領域跨文化量表翻譯指南，原版老化期望量表經過前譯、後譯、合成、預實驗和專家諮詢法等形成最終中文簡版老化期望量表。依便利抽取中國唐山社區老人458名，運用探索性因子分析和驗證性因子分析方法檢驗簡版量表的信度與效度。結果：中文簡版老化期望量表內容效度指數為0.831。量表的整體Cronbach 係數為0.953，分半信度分別為0.904和0.933。驗證性因子分析中提取了三個因子，累積方差貢獻率為84.24％，該模型擬合良好。除身體健康維度外，收斂效度和區分效度均在可接受範圍內。結論：中文簡版老化期望量表信度與效度良好，可用於評估中國老年人老化期望情況。
