Health Behavior Change Design
We apply behavioral medicine and design to health behavior change, helping organizations build programs and products that make healthy actions easier to start, more rewarding to repeat and more likely to last.
The problem behind the problem.
Most people already know they should move more, sleep better, take their medications or attend screenings. The gap is not information; it is translating intention into consistent action amid busy lives, competing priorities, cost, stress and habit. Yet many health programs still rely primarily on education and reminders, assuming that knowledge will produce behavior. When participation drops, the response is often more messages, which people quickly and understandably learn to ignore.
Health behavior change is also highly individual and contextual. A person managing diabetes while working night shifts faces different barriers than a retiree with limited mobility or a young parent with little time. Programs designed for an imagined average participant miss most real ones. Without careful diagnosis, segmentation by behavior and testing, organizations invest in interventions that look sensible but fail to move the behaviors that actually influence health outcomes.
How we deliver health behavior change design.
- 01Observe
Understand behavior in context
We interview participants, caregivers and frontline staff, and observe where the target behavior does or does not happen. Contextual inquiry and journey mapping reveal real barriers: confusing instructions, time conflicts, costs, side effects, low confidence or competing demands. We pay attention to health literacy and cultural context, which often explain more than motivation alone.
- 02Signal
Find the behaviors that predict outcomes
We analyze program, claims, app or clinical data to identify the specific behaviors and early moments that predict longer-term engagement and health outcomes. We look for behavioral types, such as people who start strong then fade, and the conversion points where participants commit or drop out. These become predictive KPIs for the program.
- 03Design
Match interventions to barriers
Using COM-B, the Fogg Behavior Model and self-determination theory, we design interventions matched to each barrier: simpler first steps, well-timed prompts, implementation intentions, social support, feedback and motivational interviewing techniques that strengthen a person's own reasons for change. We respect autonomy throughout, avoiding pressure tactics that undermine long-term motivation.
- 04Test
Pilot and compare
We test interventions through pilots, A/B tests or staged rollouts, measuring both immediate behaviors and longer-term engagement. Where clinical outcomes are relevant, we work with clinical partners to design appropriate evaluation. Usability testing ensures that materials and tools are understandable to participants with varied health literacy and abilities.
- 05Scale
Implement and sustain
We help teams roll out successful interventions, train staff in behavior change techniques such as motivational interviewing, and build dashboards that track predictive KPIs. We plan for maintenance as well as initiation, since many health behaviors fade after initial enthusiasm, and we design supports that help participants recover after lapses rather than giving up.
Deliverables.
What changes.
Who engages us.
We work with health systems, payers, digital health companies, employers, public health agencies, community organizations and wellness providers. Clients include program directors, population health leaders, product managers and clinical leaders. Typical triggers are low enrollment or high dropout in a health program, a new prevention or chronic disease management initiative, disappointing results from an existing intervention, or a funder asking for stronger evidence of behavior change.

Beyond the balance sheet.
Health behavior change is one of the most direct ways behavioral science serves the social good. Small, sustained changes in activity, nutrition, sleep, medication use or screening can meaningfully improve quality of life. Designing for health literacy and real constraints helps programs reach people who are often underserved. Employees, patients and members benefit from support that respects their autonomy, and communities benefit when prevention works before illness becomes costly and disruptive.
Frequently asked questions.
What models of health behavior change do you use?
We draw on several established frameworks, choosing based on the problem. COM-B helps diagnose whether capability, opportunity or motivation is the main barrier. The Fogg Behavior Model highlights the role of ability and prompts. Self-determination theory guides how to support lasting motivation through autonomy, competence and connection. Motivational interviewing informs conversations that strengthen people's own reasons for change.
Why do health programs that rely on education often fail?
Most people already know what they should do. Information addresses capability, but behavior also depends on opportunity, such as time, access and cost, and on motivation, including habits and emotions. Education alone rarely changes these. Effective health behavior change design identifies the specific barriers for specific groups and designs interventions that make the healthy behavior easier, more prompted and more rewarding.
How do you make sure behavior change design is ethical?
We design to help people do what they already want to do for their own health. That means transparency, respect for autonomy, avoiding fear-based or shaming messages, and protecting privacy in data use. We test materials with participants, including people with limited health literacy, and we decline approaches that exploit vulnerability. Ethical persuasion tends to produce more durable behavior change as well.
Can you help us evaluate an existing health program?
Yes. We often start with an existing program, analyzing participation data, interviewing participants and staff, and mapping where people drop out. This diagnosis usually reveals a few points where targeted redesign can improve engagement. We then help design and test changes, rather than rebuilding the program from scratch, and we define the measures that will show whether those changes are working.
