We propose the Multimodal Intrapersonal and Interpersonal Dynamics (MIND; Atzil-Slonim, 2025), a shared transtheoretical process language that integrates insights from diverse psychotherapy theories and empirical findings to identify the intrapersonal and interpersonal dynamics linked to therapeutic change. The MIND provides its theoretical framework and empirical implementation by breaking down patients' experiences into well-accepted core experiential building blocks (Affect, Behavior, Cognition, Desire [ABCD]; Revelle, 2007) and therapist interventions (McCullough, 1988). It offers both a common language for representing how these elements co-occur and interact moment-by-moment in therapy, and a foundation for translating and teaching AI models the fundamental concepts of complex psychotherapeutic constructs.
