28 +We used a modified version of the Godspeed questionnaire for our evaluation [1]. It measures the anthropomorphism, animacy, likeability, intelligence, and safety of the robot. This uses a Likert scale where the user must rate questions as a number between 1 and 5; both numbers being at opposite poles. To measure whether patients with dementia completed the activity they were meant to do, and to evaluate whether storytelling made a difference to their meal, we added the following questions:
