Every SAF chain starts the same way: a sequence of numbers that becomes a Lead, a Core, and an Anchor. But there are two different ways to actually generate that sequence, and which one you use depends on what's available to you and where you are.
The questionnaire: free, remote, and always available
The Stress-120 questionnaire (alongside the related SAF-120 and Q-24 formats) is free to complete and can be done from anywhere. It presents a subjective viewpoint: your priorities and your reality as you currently see them, with probable causes that may not be obvious to you yet. This is the method used for every remote SAF Chain Interpretation session booked through this site, conducted by Zoom.
The infrared scan: in-person, and a different kind of data
An infrared scan, taken with the ExTech IR 200 sensitizer (typically on the face), works differently. It's designed to pick up on nuances that aren't filtered through conscious self-report, translating that directly into a SAF sequence. Because it requires the physical device and a practitioner to administer it, it's an in-person method only, it isn't part of a remote session, and it's introduced formally in Course 2 training.
Neither one is "more correct"
Both methods are producing the same kind of chain, read the same way, through Lead, Core, and Anchor. The questionnaire surfaces what you already sense about yourself; the infrared scan surfaces what your body is communicating independent of what you'd consciously report. They're two doors into the same room.
What this means if you're booking a session
If you're booking a SAF Chain Interpretation session with us, it's conducted remotely by Zoom using the Stress-120 questionnaire only. If you're training toward practitioner certification, infrared work is introduced in Course 2, and the device itself is available in our bookstore.
