Advancing mental health through clinical insight, scientific inquiry, and measurable progress. Kathryn A Walker is helping shape a future where human experience is heard, studied, and understood across communities, cultures, and countries.
Mental health deserves to be understood and followed over time. The Federal Unit Scale offers a new, brief approach to checking in with yourself through five questions—making measurement more approachable in everyday life.
We invite everyone to learn to measure their mental health: to better understand their experience, notice changes early, and make wiser, more informed decisions about seeking support. Regular check-ins can open conversations about prevention and care, helping you bring greater awareness and intention to your well-being.
Start your mental health check-in
Kathryn A Walker, CRNA, PMHNP, APRN, brings the perspective of critical care, anesthesia, and psychiatric practice to one of the most urgent questions in healthcare: how can we better understand mental suffering and meaningfully measure improvement? Her work brings clinical experience into dialogue with neuroscience, published research, and the lived experiences of the people seeking care.
As an author, clinician, and research collaborator, Kathryn is helping move that conversation forward. Her contributions include peer-reviewed work on mental health measurement, ketamine, psychotherapy, and post-traumatic stress. Through the Inflamed books and the developing Love, Safety, and Trust framework, she also translates complex questions about the mind into language people can explore in their own lives.
Mental health is moving further into the wider conversation about human health: how we sleep, connect, work, recover, and participate in our communities. The challenge is both deeply personal and global. The World Health Organization reported in 2025 that more than one billion people live with mental health conditions, while access to adequate care remains uneven.
Kathryn’s mission is to help meet that challenge through scientific inquiry, practical education, and a more complete understanding of the person. Progress means asking better questions, testing ideas, listening carefully, and measuring whether care makes a meaningful difference over time.
Kathryn’s leadership connects the questions that emerge in clinical care with the research needed to examine them.
As a co-author of the Federal Unit Scale validation study, Kathryn contributed to research examining a brief, five-question assessment of broad psychological distress. The study included a clinical sample of 1,798 people and a crowdsourced sample of 10,000, investigating reliability and relationships with established mental health measures.

A global vision requires more than taking one model everywhere. It requires listening to how people understand health within their own lives, languages, and communities.
From veterans and frontline professionals to families and local care teams, the goal is to make conversations about mental health more approachable and progress easier to communicate. Meaningful measurement should support a person’s story and help inform care.
Language, values, relationships, and circumstances shape how distress is expressed. Kathryn’s vision calls for culturally responsive collaboration and careful testing of tools in the populations they are intended to serve. Cross-cultural applicability remains an important area for further FUS research.
International research collaboration creates opportunities to share methods, question assumptions, and learn across healthcare settings. Kathryn welcomes clinicians, researchers, educators, and community leaders who want to advance that work together.
Help build a future where mental health is taken seriously, studied thoughtfully, and supported with compassion.

Research shows a two-way relationship: physical illness can increase the risk of depression, and depression is associated with a higher risk of several chronic physical conditions. LST’s vision is to help practitioners address that connected experience through a common framework, within their professional scope.
People with diabetes are two to three times as likely to have depression as people without diabetes.
