To translate, cross-culturally adapt, and validate the Malnutrition Awareness Scale (MAS) among Chinese community-dwelling older adults.
This study consists of two parts. First, we developed the Chinese version of the MAS (C-MAS) through direct translation, back translation, cross-cultural adaptation, and pilot testing. Then, we selected 380 community-dwelling older adults from two community healthcare centers in Zhengzhou from May to July 2024 for a questionnaire survey to assess the scale's reliability and validity, including internal reliability, test-retest reliability, split-half reliability, content validity, and construct validity.
The C-MAS included 4 dimensions and 23 items. At the scale level, the content validity index (S-CVI) was 0.91; at the item level, the content validity ranged from 0.86 to 1.00. The exploratory factor analysis (EFA) extracted four common factors with factor loads of 0.646 to 0.893 for each item, and the cumulative variance contribution rate was 71.418%. The confirmatory factor analysis (CFA) indicated a satisfactory fit for each indicator. The Cronbach's alpha coefficient for this scale was 0.908, with test-retest reliability of 0.952 and split-half reliability of 0.738.
The reliability and validity of C-MAS are up to standard and can be used to assess malnutrition awareness among Chinese community-dwelling older adults.
对营养不良认知量表（MAS）进行翻译、跨文化调适并在中国社区居住的老年人中进行验证。
本研究包括两个部分。首先，我们通过直接翻译、回译、跨文化调适和预试验开发了中文版的MAS（C-MAS）。然后，我们于2024年5月至7月从郑州的两个社区卫生服务中心选取了380名社区居住的老年人进行问卷调查，以评估该量表的信效度，包括内部信度、重测信度、分半信度、内容效度和结构效度。
C-MAS包括4个维度和23个条目。在量表层面，内容效度指数（S-CVI）为0.91；在条目层面，内容效度范围为0.86至1.00。探索性因子分析（EFA）提取了四个共同因子，每个条目的因子载荷为0.646至0.893，累积方差贡献率为71.418%。验证性因子分析（CFA）表明各指标拟合良好。该量表的Cronbach's alpha系数为0.908，重测信度为0.952，分半信度为0.738。
C-MAS的信效度达到标准，可用于评估中国社区居住老年人的营养不良认知情况。
