Validation of Quality-of-Life assessment tool for Ethiopian old age people

Background: Reliable quality of life assessment is critical for identifying health issues, evaluating health interventions, and establishing the best health policies and care packages. The World Health Organization Quality of Life-Old Module is a tool for assessing the subjective quality of life in old age people. It's validated and available in more than 20 languages, except Amharic. Hence, this study was intended to translate it into Amharic language and validate it among old age people in Ethiopia.
Methods: A cross-sectional study was conducted among 180 community-dwelling old age people in Ethiopia, from January 16 to March 13, 2021. Psychometric validation was achieved through Cronbach’s alpha of the internal consistency reliability test, and construct validity from confirmatory factor analysis.
Results: The study participants aged from 60 to 90 years old with a mean age of 69.44. Females made up 61.7% of the population, and 40% of them could not read and write. The results showed ..., Study setting
This study was conducted in Ethiopia.
Study design and period
A cross-sectional study design was conducted from January 16 to March 13, 2021.
Study population, sample size and sampling procedures  
This study utilized two groups of the population. The first group was health care experts used for content validation, and the second group was community-dwelling old age people for psychometric validation. The detailed study methods for study population, sample size, and sampling procedures were described in the previous study.
Validation process
This tool validation study was conducted in three stepwise phases. The first phase was to review existing QoL assessment tools for old age people. In the second phase, selection, translation, and review of the tool by experts were conducted. In the last phase, psychometric validation among community-dwelling old age people was performed.
The novel form contains a total of 24 items assembled into six domains, each with four items: auton..., The international business machines corporation statistical package for the social science (IBM SPSS) can be used to open the data.

背景：可靠的生活质量（Quality of Life, QoL）评估对于识别健康问题、评估健康干预措施以及制定最优卫生政策与照护方案至关重要。世界卫生组织老年生活质量模块（World Health Organization Quality of Life-Old Module）是用于评估老年人主观生活质量的工具。该工具已在20余种语言中完成验证并投入使用，但阿姆哈拉语（Amharic）版本暂未覆盖。因此本研究旨在将其翻译为阿姆哈拉语，并在埃塞俄比亚老年人群中开展验证工作。
方法：本研究于2021年1月16日至3月13日在埃塞俄比亚开展，纳入180名社区居住的老年人作为研究对象。通过内部一致性信度检验的克朗巴赫α系数（Cronbach’s alpha）以及验证性因子分析（confirmatory factor analysis）得到的结构效度，完成该工具的心理测量学验证。
结果：本研究参与者年龄介于60至90岁之间，平均年龄为69.44岁。女性占总研究人群的61.7%，其中40%的参与者不具备读写能力。研究结果显示……
研究地点：本研究在埃塞俄比亚开展。
研究设计与周期：本研究采用横断面研究设计，研究周期为2021年1月16日至3月13日。
研究人群、样本量与抽样流程：本研究纳入两组人群：第一组为用于内容效度验证的医疗卫生专家，第二组为用于心理测量学验证的社区居住老年人。有关研究人群、样本量及抽样流程的详细方法已在既往研究中予以说明。
验证流程：本工具验证研究分为三个逐步推进的阶段：第一阶段为梳理现有老年生活质量评估工具；第二阶段为工具的遴选、翻译及专家评审；第三阶段为在社区居住老年人中开展心理测量学验证。
