Eye tracking

Attribute attendance is a fundamental assumption of discrete choice experiments, a commonly used technique for investigating individual health preferences. When attribute attendance is not accomplished (also called attribute non-attendance) it presents a serious risk to the validity of the outcomes of discrete choice experiments.

One possible method for the assessment of attribute attendance is eye-tracking in which the gaze of a participant is tracked to see where they are looking during a choice task. However, there is limited research that uses eye-tracking to assess attribute attendance during choice task completion, and what research has been done frequently does not use patient populations.

The aim of this study is to investigate attribute non-attendance in different patient populations and disease contexts (i.e. group, disease, previously determined attributes of interest), and how risk attribute presentation formats impacts attribute non-attendance in different patient populations and disease contexts using use eye-tracking techniques.
