How Flexible is Your Mindset?

Aug 7, 2025 | Assessments, Behavior Change, Mindset, Performance, Resilience, Stress Management

When stress hits, do you freeze, fight, or flex?

This quick, science-backed assessment reveals your Mindset Flexibility Score—a snapshot of how well you adapt, stay grounded, and move forward when things get challenging.

Your score is based on psychological flexibility, the foundation of resilience. It reflects your ability to:

  • Stay present (instead of spiraling into worry or avoidance)
  • Accept difficult thoughts and emotions without being ruled by them
  • Take meaningful action, even when life feels messy or uncertain

It’s not about being perfect—or always calm.

It’s about having the ability to respond in any situation with greater clarity and ease. 

No one is 100% flexible.  But this assessment will help you notice what’s already working, what you may want to change, and what’s possible for a better future.

(Takes just a few minutes. Instant results.)
