Same study, different questions

HCI

What are the critical design decisions that will drive adults with or at risk for cardiovascular disease who are enrolled in an online walking program to participation in an online community

Behavioral Science

Among Adults with or at risk for cardiovascular disease, does adding a well designed Online community to an internet Mediated Walking Program increase adherence and step counts.

Comparison

HCI Emphasis

Design and creation of usable and useful artifacts

Publications Conferences

What’s funded Novel lines of inquiry,

particularly creation of “new” systems and processes.

Behavioral Science Emphasis

Development and evaluation of health interventions

Publications Journals

What’s funded Evaluation of

interventions, particularly those that have already been “vetted”

How might HCI help behavioral science?

Development of systems people want to use

Help reduce likelihood of Type III Error

Theoretical fidelity of intervention components

Opportunities for “big data” & A/B testing
