Secure-Functioning Relationships

How to build a relationship where both people genuinely feel safe

What does it mean to be a secure-functioning couple and how do you get there?

Secure functioning, as defined by Stan Tatkin’s PACT model, means both partners operate as a team that actively manages each other’s safety and security — rather than each person managing their own needs separately. The model has a strong mechanistic basis in attachment neuroscience; formal RCT evidence for PACT specifically is limited but growing.

Stan Tatkin, a clinician and researcher who trained with Dan Siegel and at the UCLA Mindful Awareness Research Center, developed PACT — Psychobiological Approach to Couples Therapy — around one core principle: adult intimate relationships are meant to be the primary attachment bond for both partners, and that bond requires active, mutual management of each other’s nervous systems. Most relationship friction, Tatkin argues, happens not because people are bad partners but because they manage their own stress privately instead of co-managing it together. Below are the key practices with honest reads on the mechanisms and the evidence.
