The aim of the present study was to translate into Spanish and evaluate the psychometric evidence of the Impact on Quality of Life (COV19-QoL) applied to a sample of Peruvian older adults (N = 298; 58.1% women, 41.9% men, mean age 65.34 years [SD = 11.33]). The study used techniques from the Classical Test Theory (CTT) and Item Response Theory (IRT). The findings confirmed the single factor structure of the COV19-QoL, high internal consistency reliability, measurement invariance by gender, and all items demonstrated adequate discrimination and difficulty indices. In this sense, the items allow adequate discrimination between low, medium and high levels of the impact of the COVID-19 pandemic on quality of life. In addition, a greater perceived impact of the pandemic on quality of life is necessary to answer the higher response options of the COV19-QoL. In conclusion, the COV19-QoL is a valid measurement scale of the impact of the COVID-19 pandemic on the quality of life of Peruvian older adults.
本研究的目的是将适用于秘鲁老年人样本（N = 298；女性占58.1%，男性占41.9%，平均年龄65.34岁[标准差=11.33]）的生活质量影响量表（COV19-QoL）翻译成西班牙语并评估其心理测量学证据。该研究采用了经典测验理论（CTT）和项目反应理论（IRT）的技术。研究结果证实了COV19-QoL的单因素结构、高内部一致性信度、性别测量不变性，并且所有项目都显示出足够的区分度和难度指数。从这个意义上说，这些项目能够充分区分新冠疫情对生活质量影响程度的低、中、高三个水平。此外，为了回答COV19-QoL中更高的反应选项，需要对疫情对生活质量有更大的感知影响。总之，COV19-QoL是衡量新冠疫情对秘鲁老年人生活质量影响程度的有效测量量表。
