Measuring translation difficulty: An empirical study

The purpose of this study was to find a method to measure difficulty in a translation task. Readability formulas have been suggested to be a useful tool and yet this needs to be empirically tested. In this study, NASA Task Load Index, a multidimensional scale for measuring mental workload, was used to assess the level of translation difficulty for the translator. It was found that a text’s readability only partially accounts for its translation difficulty level. Translation quality score was found to be an unreliable indicator of translation difficulty level, while time-on-task was significantly, but weakly, related to translation difficulty level. A formula was developed to predict a text’s translation difficulty level for a translator by using the translator’s pre-translation rating.
