Three items measuring how difficult, complex, and time-consuming a particular task is perceived to be. Kaiser, Schreier, and Janiszewski (2017) developed the scale to assess participant perceptions of a product customisation task, distinguishing between choosing a pre-designed product versus designing one from scratch. The items are phrased as stem completions, allowing flexible adaptation to different task contexts.
