Older person's ability to contribute covers contributions divided into five subdomains: assisting friends and neighbours, mentoring peers and younger people, caring for family, engaging in the workforce and voluntary activity.
To evaluate the psychometric properties of ability to contribute measurements as a domain of functional ability of older persons using Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology for systematic reviews.
A systematic search was performed in PubMed, Embase and PsycINFO databases, for observational studies published within the last 10 years. The measurement properties of these ability measures were evaluated against the COSMIN taxonomy. Risk-of-bias assessment was performed using the COSMIN Risk of Bias checklist.
Of the 32,665 studies identified, we selected 19, of which the main purpose was to develop or validate an instrument or have related items that measure at least one of the subdomains. None of the instruments contained items that were fully related to the five subdomains, 60% (n = 12) were related to voluntary activities and 15% (n = 3) to mentoring peers and younger people. As for psychometric properties, two studies assessed content validity. Factor analysis was used to evaluate structural validity in 10 studies. Internal consistency was evaluated in 63% of the instruments and Cronbach's alpha ranges from 0.63 to 0.92. No study reported predictive validity. A very limited overview of their scope and limitations for their application was observed.
We found no single instrument measuring all subdomains of ability to contribute. We found several instruments containing items that could indirectly measure some of the subdomains of the ability to contribute.
老年人的贡献能力涵盖五个子领域的贡献：帮助朋友和邻居、指导同龄人及年轻人、照顾家庭、参与劳动力市场和志愿活动。
使用共识基础的健康测量仪器选择标准（COSMIN）方法学对系统综述进行评估，以确定老年人能力贡献测量作为功能能力领域的心理测量学特性。
在 PubMed、Embase 和 PsycINFO 数据库中进行了系统搜索，以查找过去 10 年内发表的观察性研究。使用 COSMIN 偏倚风险检查表评估这些能力测量的测量特性。
在 32665 项研究中，我们选择了 19 项，其中主要目的是开发或验证一种工具或具有至少一个子领域相关项目的工具。没有一种工具包含与五个子领域完全相关的项目，60%（n=12）与志愿活动有关，15%（n=3）与指导同龄人及年轻人有关。关于心理测量学特性，有两项研究评估了内容效度。结构效度使用因子分析在 10 项研究中进行评估。63%的工具评估了内部一致性，Cronbach's alpha 范围为 0.63 至 0.92。没有研究报告预测效度。对其应用范围和局限性的简要概述很少。
我们没有发现单一的工具可以测量能力贡献的所有子领域。我们发现了一些包含可以间接测量能力贡献的一些子领域的项目的工具。
