Measuring Text Comprehension for People with Reading Difficulties Using a Mobile Application

Measuring text comprehension is crucial for evaluating the accessibility of texts in Easy Language. However, accurate and objective comprehension tests tend to be expensive, time-consuming and sometimes difficult to implement for target groups of Easy Language. In this paper, we propose using computer-based testing with touchscreen devices as a means to simplify and accelerate data collection using comprehension tests, and to facilitate experiments with less proficient readers. We demonstrate this by designing and implementing a mobile touchscreen application and validating its effectiveness in an experiment with people with intellectual disabilities. The results suggest that there is no difference in terms of task difficulty between measuring comprehension using the mobile application and a traditional paper-and-pencil test. Moreover, reading times appear to be faster in the application than on paper.
