To ascertain the reliability of a standardised, short-scale measure of satisfaction in the use of new healthcare technology i.e., the LITE version of the usability metric for user experience (UMUX-LITE). Whilst previous studies have demonstrated the reliability of UMUX-LITE, and its relationship with measures of likelihood to recommend a product, such as the Net Promoter Score (NPS) in other sectors no such testing has been undertaken with healthcare technology.
Six point-of-care products at different stages of development were assessed by 120 healthcare professionals. UMUX-LITE was used to gather their satisfaction in use, and NPS to declare their intention to promote the product. Inferential statistics were used to: i) ascertain the reliability of UMUX-LITE, and ii) assess the relationship between UMUX-LITE and NPS at different stages of products development.
UMUX-LITE showed an acceptable reliability (α = 0.7) and a strong positive correlation with NPS (r = 0.455, p < .001). This is similar to findings in other fields of application. The level of product development did not affect the UMUX-LITE scores, while the stage of development was a significant predictor (R = 0.49) of the intention to promote.
Practitioners may apply UMUX-LITE alone, or in combination with the NPS, to complement interview and 'homemade' scales to investigate the quality of new products at different stages of development. This shortened scale is appropriate for use in the context of healthcare in which busy professionals have a minimal amount of time to support innovation.
确定一种新的医疗保健技术（即用户体验可用性度量的精简版（UMUX-LITE））使用满意度的标准化短尺度测量的可靠性。虽然之前的研究已经证明了 UMUX-LITE 的可靠性，以及它与产品推荐可能性的衡量标准（如其他行业的净推荐值（NPS））之间的关系，但在医疗保健技术方面尚未进行过此类测试。
120 名医疗保健专业人员评估了处于不同开发阶段的 6 种即时护理产品。使用 UMUX-LITE 来收集他们对使用的满意度，使用 NPS 来声明他们推广产品的意愿。使用推理统计来：i）确定 UMUX-LITE 的可靠性，以及 ii）评估产品开发的不同阶段 UMUX-LITE 和 NPS 之间的关系。
UMUX-LITE 表现出可接受的可靠性（α=0.7），与 NPS 呈强烈正相关（r=0.455，p<0.001）。这与其他应用领域的发现相似。产品开发的水平不会影响 UMUX-LITE 的分数，而开发阶段是促进意愿的重要预测指标（R=0.49）。
从业者可以单独使用 UMUX-LITE，或者与 NPS 结合使用，以补充访谈和“自制”量表，在不同的开发阶段调查新产品的质量。这种缩短的量表适用于医疗保健领域，因为忙碌的专业人员支持创新的时间非常有限。
