How they work
ACT
Core mechanism: Psychological flexibility through acceptance, defusion, present-moment awareness, values clarification, and committed action
Ontology: Psychological inflexibility: cognitive fusion and experiential avoidance narrow behavioral repertoire
Compassion-Focused Therapy
Core mechanism: Activating the soothing/affiliative system through compassion practices counteracts threat-based shame and self-criticism
Ontology: Shame and self-criticism driven by overactive threat system and underdeveloped soothing/safeness system

What each assumes — and misses
ACT
Philosophical roots: Pragmatism (James, Dewey — truth as workability); functional contextualism (Pepper); Buddhism (attachment as suffering, mindfulness); Skinner (radical behaviorism, reframed)
Blind spots: Acceptance framing can feel dismissive of legitimate suffering; metaphor-heavy approach may not land for all clients
Therapeutic voice: What if the goal isn't to get rid of the anxiety, but to take it with you toward what matters?
Compassion-Focused Therapy
Philosophical roots: Buddhist compassion practices (Dalai Lama, Shantideva); evolutionary psychology (Gilbert — three emotion regulation systems); attachment theory; Neff (self-compassion research)
Blind spots: Compassion imagery can paradoxically increase distress in highly shame-prone individuals initially; limited outside depression/shame
Therapeutic voice: Imagine your compassionate self — wise, strong, warm. What would that self say to you right now?
Choosing between them
ACT and Compassion-Focused Therapy both sit within the Cognitive-Behavioral tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
