How Self-Affirmation Fuels Behavior Change

One of the foundational pieces of research informing the science behind Purposeful and Kumanu’s approach to behavior change is a 2015 study published in the Proceedings of the National Academy of Sciences (PNAS). While not new, this study remains profoundly relevant to how we understand the role of purpose and values in supporting well-being today.

The study, titled "Self-affirmation alters the brain’s response to health messages and subsequent behavior change," was conducted by a team of respected researchers including Dr. Emily Falk, Dr. Ken Resnicow, and Dr. Vic Strecher—all members of Kumanu’s Science Advisory Board. This research offers deep insight into the neurological underpinnings of motivation and behavioral response, aligning closely with the core philosophy that drives Kumanu’s work.

Key Findings

Using functional MRI (fMRI), the study showed that individuals who engaged in self-affirmation prior to receiving health messages exhibited increased activity in key brain regions associated with self-related processing and valuation. These neurological changes were also linked to improved health behaviors—such as increased physical activity—weeks after the intervention.

In essence, reflecting on personal values primes the brain to be more receptive to positive change, making health messages more effective and actionable.

Relevance to Kumanu’s Mission

At Kumanu, we believe that purpose and values aren’t just abstract concepts—they are scientifically validated drivers of human behavior. This study offers a foundational link between psychological interventions and physiological outcomes, reinforcing the design of Kumanu’s Purposeful platform, which helps users identify and act on what matters most to them.

By centering well-being strategies on personal purpose and values, we support sustainable behavior change, increased resilience, and improved health outcomes. The research by Falk, Resnicow, Strecher, and their collaborators gives us even more confidence in the efficacy of our approach.

A Science-Driven Future

The inclusion of Drs. Falk, Resnicow, and Strecher on our Science Advisory Board ensures that Kumanu remains rooted in leading-edge behavioral science. Their groundbreaking work continues to guide our development of purpose-centered well-being solutions that are not only meaningful but measurable.
