  Healthcare professionals use Activities of Daily Living (ADL) to characterize
a patient's functional status and to evaluate the effectiveness of treatment
plans. ADLs are traditionally measured using standardized text-based
questionnaires and the only form of personalization is in the form of question
branching logic. Pervasive smartphone adoption makes it feasible to consider
more frequent patient-reporting on ADLs. However, asking generic sets of
questions repeatedly introduces user burden and fatigue that threatens to
interfere with their utility. We introduce an approach called YADL (Your
Activities of Daily Living) which uses images of ADLs and personalization to
improve survey efficiency and the patient-experience. It offers several
potential benefits: wider coverage of ADLs, improved engagement, and accurate
capture of individual health situations. In this paper, we discuss our system
design and the wide applicability of the design process for survey tools in
healthcare and beyond. Interactions with with a small number of patients with
Arthritis throughout the design process have been promising and we share
detailed insights.
