BACKGROUND
Awareness of nutrition self-efficacy dimensions can enable healthcare providers to guide their use in screening and providing a context for positive changes such as in promoting a healthy lifestyle and quality care among elderly people.
OBJECTIVES
Developing an instrument for assessing nutrition self-efficacy among Iranian elderly population.
METHODS
A sequential mixed exploratory design was applied to clarify and determine dimensions of nutrition self-efficacy in a community-dwelling elderly population in two phases. The first phase included a related literature review and a qualitative study. The validity and reliability of the tool were investigated in the second phase. The instrument's content validity was assessed by experts in nutrition self-efficacy's field and reliability was determined by internal consistency and construct reliability.
RESULTS
Three factors (adherence efficacy, preventive behaviors, and information effectiveness) and 29 items were obtained after assessing the face, content, and construct validity. The reliability of the nutrition self-efficacy questionnaire (NSEQ) exceeded α > 0.7. Concerning the cumulative percent of the variance, the three factors determined 64.05% of the total variance.
CONCLUSIONS
The NSEQ designed in this study, using the background experiences of the elderly living in the community and a review of related texts, and has acceptable reliability and validity. However, the diet self-efficacy questionnaire cannot yet be used as a gold standard, but it can be recommended for use as a measurement of individual diet self-efficacy in a community-dwelling elderly population.
背景
了解营养自我效能维度能够使医疗保健提供者在筛查中指导其应用，并为积极改变提供背景，比如在促进老年人健康生活方式和优质护理方面。
目的
开发一种用于评估伊朗老年人群营养自我效能的工具。
方法
采用序贯混合探索性设计分两个阶段阐明并确定社区居住老年人群营养自我效能的维度。第一阶段包括相关文献综述和定性研究。第二阶段对该工具的效度和信度进行调查。通过营养自我效能领域的专家评估该工具的内容效度，并通过内部一致性和结构信度确定信度。
结果
在评估了表面效度、内容效度和结构效度后，得到了三个因素（依从效能、预防行为和信息有效性）及29个条目。营养自我效能量表（NSEQ）的信度超过α>0.7。就方差的累积百分比而言，这三个因素决定了总方差的64.05%。
结论
本研究设计的NSEQ利用了社区居住老年人的背景经验并对相关文献进行了综述，具有可接受的信度和效度。然而，饮食自我效能量表尚不能作为金标准使用，但可推荐用于测量社区居住老年人群的个体饮食自我效能。
