Abstract

Single-item scales of perceived usability are attractive due to their efficiency and non-verbal scales are attractive because they enable collecting data from individuals irrespective of their language proficiency. We tested experimentally whether single-item verbal and pictorial scales can compete with their 10-item counterparts at reflecting the difference in usability between well-designed and poorly designed systems. N = 1079 (Experiment 1) and N = 1092 (Experiment 2) participants worked with two systems whose usability was experimentally manipulated. Perceived usability was assessed using the 10-item System Usability Scale, the single-item Adjective Rating Scale, the 10-item Pictorial System Usability Scale and the Pictorial Single-Item Usability Scale. The single-item scales reflect the difference in usability as good as their 10-item counterparts. The pictorial scales are nearly as valid as their verbal counterparts. The single-item Adjective Rating Scale and the Pictorial Single-Item Usability Scale are thus efficient and valid alternatives to their 10-item counterparts.

在衡量感知可用性方面，语言和图形单项量表与 10 项量表一样好用。

感知可用性的单项量表因其高效性而颇具吸引力，而非语言量表则因其能够从个人那里收集数据而颇具吸引力，无论他们的语言水平如何。我们通过实验测试了单项语言量表和图形量表在反映设计良好和设计不佳系统之间可用性差异方面是否能与 10 项量表相媲美。N = 1079 人（实验 1）和 N = 1092 人（实验 2）的参与者使用了两个系统，这两个系统的可用性受到实验操纵。使用 10 项系统可用性量表、单项形容词评定量表、10 项图示系统可用性量表和图示单项可用性量表对感知可用性进行评估。单项量表与 10 项对应量表一样，都能很好地反映可用性的差异。图形量表的有效性几乎与语言量表相同。因此，单项形容词评定量表和图形单项可用性量表可以有效替代 10 项对应量表。

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
