The four-quadrant translation map
Most clinical concepts can be located along two axes: target (cognition / emotion / behavior / relational pattern) and level (symptom-focused / mechanism-focused). 'Worry log' (CBT), 'thought diary' (CBT), 'observing thoughts as leaves on a stream' (ACT), and 'noticing the inner critic' (IFS) all sit in the cognition-symptom quadrant. They differ in metaphor and theory of change, but the in-session move is structurally similar: create distance between the client and a thought stream. Mapping concepts to quadrants before translating prevents superficial swaps that lose mechanism.
