Computerized Quality of Life Assessment: A Randomized Experiment to Determine the Impact of Individualized Feedback on Assessment Experience

Background: Quality of life (QoL) assessments, or patient-reported
outcome measures (PROMs), are becoming increasingly important in
health care and have been associated with improved decision making,
higher satisfaction, and better outcomes of care. Some physicians
and patients may find questionnaires too burdensome; however, this
issue could be addressed by making use of computerized adaptive
testing (CAT). In addition, making the questionnaire more
interesting, for example by providing graphical and contextualized
feedback, may further improve the experience of the users. However,
little is known about how shorter assessments and feedback impact
user experience. Objective: We conducted a controlled experiment to
assess the impact of tailored multimodal feedback and CAT on user
experience in QoL assessment using validated PROMs. Methods: We
recruited a representative sample from the general population in
the United Kingdom using the Oxford Prolific academic Web panel.
Participants completed either a CAT version of the World Health
Organization Quality of Life assessment (WHOQOL-CAT) or the
fixed-length WHOQOL-BREF, an abbreviated version of the WHOQOL-100.
We randomly assigned participants to conditions in which they would
receive no feedback, graphical feedback only, or graphical and
adaptive text-based feedback. Participants rated the assessment in
terms of perceived acceptability, engagement, clarity, and
accuracy. Results: We included 1386 participants in our analysis.
Assessment experience was improved when graphical and tailored
text-based feedback was provided along with PROMs (Δ=0.22, P
