How they work
Common Factors / Contextual Model
Core mechanism: Therapeutic change is primarily driven by factors common to all therapies — the alliance, therapist empathy, client expectations, and the provision of a healing ritual — not by specific techniques
Ontology: Humans heal through relationships, hope, and meaning-making rituals; specific techniques are vehicles for these universal healing processes, not the active ingredients themselves
Multimodal Therapy
Core mechanism: Systematic assessment across all seven modalities of human functioning (BASIC I.D.) identifies the specific constellation of problems and firing order, enabling targeted interventions drawn eclectically from any effective tradition
Ontology: Human problems are multimodal — they involve behavior, affect, sensation, imagery, cognition, interpersonal patterns, and biology in varying combinations; single-modality treatments miss the full picture

What each assumes — and misses
Common Factors / Contextual Model
Philosophical roots: Rosenzweig (common factors, 1936); Frank & Frank (Persuasion and Healing); Wampold (contextual model); Rogers (necessary and sufficient conditions); social psychology of healing
Blind spots: Can be used to dismiss the value of specific training; 'everything works equally' is an oversimplification; doesn't help clinicians choose what to do with a specific client; political implications (threatens modality-specific training programs)
Therapeutic voice: This framework doesn't have a therapeutic voice — it's the lens that asks: what's actually doing the healing across all our different approaches?
Multimodal Therapy
Philosophical roots: Pragmatism (what works regardless of theory); Lazarus explicitly rejected theoretical integration in favor of technical eclecticism; behaviorism (Lazarus trained with Wolpe); empiricism; Korzybski (general semantics — the map is not the territory)
Blind spots: Technical eclecticism risks superficiality — borrowing techniques without understanding their theoretical context; framework is descriptive rather than explanatory; limited controlled research
Therapeutic voice: Let's map the full picture — what's happening in your behavior, feelings, body, images, thoughts, relationships, and health?
Choosing between them
Common Factors / Contextual Model and Multimodal Therapy both sit within the Integrative 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.
