Abstract：
The aim of this study was to adapt the National Aeronautics and Space Administration Task Load Index (NASA-TLX) to the home care setting and translate and validate it in Italian. An online questionnaire containing the Italian version of the NASA-TLX adapted to the home care setting was administered to home care nurses to measure workload. Content Validity Index, Exploratory, and Confirmatory Factor Analyses were used to measure the psychometric characteristics of the modified NASA-TLX. The modified Italian version of NASA-TLX_HC-IT showed good psychometric characteristics in measuring the workload of home care nurses, with excellent fit indices. The reliability, calculated with Cronbach\'s alpha, was 0.73, indicating adequate reliability. A negative correlation between workload and job satisfaction among home care nurses, as well as a positive association between high workload and intention to leave the workplace, was verified. The modified Italian version of the NASA-TLX_HC-IT was confirmed to be a valid and reliable instrument to measure workload in home care nursing. Furthermore, the correlation between workload and the intention to leave the workplace among home care nurses was an important result that community nursing managers should consider preventing the shortage of home care nurses.
摘要：
这项研究的目的是使美国国家航空航天局任务负荷指数（NASA-TLX）适应家庭护理环境，并用意大利语进行翻译和验证。对家庭护理护士进行了在线问卷调查，其中包含适用于家庭护理环境的意大利版NASA-TLX，以衡量工作量。内容有效性指数，探索性的,和验证性因素分析用于测量改良的NASA-TLX的心理测量特征。修改后的意大利语版本的NASA-TLX_HC-IT在测量家庭护理护士的工作量方面显示出良好的心理测量特征，具有出色的拟合指数。可靠性,用克朗巴赫的阿尔法计算，为0.73，表明有足够的可靠性。家庭护理护士工作量与工作满意度呈负相关，以及高工作量和离开工作场所的意图之间的积极关联，已核实。经修改的意大利语版本的NASA-TLX_HC-IT被确认为有效且可靠的工具，可用于测量家庭护理护理中的工作量。此外，家庭护理护士的工作量与离开工作场所的意愿之间的相关性是社区护理管理者应考虑防止家庭护理护士短缺的重要结果。
