RSTI Stress-Type Test Guide
What is RSTI?
RSTI (Riso-Hudson Stress Type Indicator) is a stress assessment built on the Enneagram, developed by Don Richard Riso and Russ Hudson.
The Enneagram sorts people into 9 core types; each behaves differently when healthy versus under stress. RSTI specifically measures your stress responses.
The Enneagram at a Glance
- Type 1 The Perfectionist: principled, seeks correctness and improvement
- Type 2 The Helper: attentive to others' needs, generous
- Type 3 The Achiever: goal-driven, seeks success and recognition
- Type 4 The Individualist: sensitive and unique, seeks depth and meaning
- Type 5 The Observer: rational and independent, values knowledge
- Type 6 The Skeptic: vigilant and cautious, seeks security
- Type 7 The Enthusiast: upbeat and playful, seeks fresh experiences
- Type 8 The Challenger: forceful and decisive, takes control
- Type 9 The Peacemaker: gentle and accommodating, avoids conflict
Your reaction pattern under stress
Under stress each type shifts in a specific direction; the classic three chains:
- 1-4-2 chain: under stress Type 1 turns moody (toward 4); secure, it grows helpful (toward 2)
- 3-6-9 chain: under stress Type 3 grows anxious (toward 6); secure, it relaxes (toward 9)
- 9-6-3 chain: under stress Type 9 gets anxious (toward 6); secure, it takes action (toward 3)
- 4-2-8, 5-7-8, 8-5-7 chains, etc.: stress responses in other directions
How to handle stress in a healthy way?
Knowing your stress type isn't about labels — it's about awareness. Suggestions:
- Spot your triggers: know which situations flip you into stress mode (Type 1: "unfairness"; Type 6: "uncertainty")
- Pause and reflect: stress responses run on autopilot; awareness lets you pause and respond deliberately
- Return to center: regulate with your healthy-state strengths (every type has them)
- Seek help when needed: if stress keeps disrupting life or work, see a professional counselor
This is a simplified self-assessment; the full RSTI should be taken with a professional. Results support self-exploration only.
