Common Factors / Contextual Model
Common Factors / Contextual Model is a body of research rather than a therapy: Saul Rosenzweig framed the question in 1936, Jerome Frank developed it in Persuasion and Healing (1961), and Bruce Wampold's Contextual Model, set out from 2001, is its principal contemporary statement. Its core mechanism: therapeutic change runs mainly through what bona fide therapies share: the real relationship, the expectations set up by a credible rationale, and the enactment of health-promoting actions. Techniques are not inert, since a treatment needs a coherent rationale and actions that follow from it, but the differences between techniques account for little of the outcome. This catalogue links it to depression, anxiety and PTSD, typically all formats.

Ontology
Humans heal through relationships, hope, and meaning-making rituals; specific techniques are vehicles for these universal healing processes, not the active ingredients themselves
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?"
View of the Person
A relational being who heals through connection, hope, and the experience of being understood, regardless of which theoretical map the therapist carries

Framework — unranked
This entry describes a framework. A treatment evidence tier does not apply; its recorded source material remains under review.
Guidelines and official sources (2)
2 professional reference checks
Read the recommendation and its scope. A source may discuss an approach without recommending it.
- What the evidence shows: psychotherapy relationships
Discussed in the source
The task-force report identifies alliance among effective relationship factors. This is not a condition-specific recommendation for a standalone Contextual Model treatment.
Scope: Relationship factors across individual, youth, couple and family psychotherapy.
- The Alliance in Adult Psychotherapy: A Meta-Analytic Synthesis
Discussed in the source
This task-force-linked synthesis examines alliance and outcome associations. It does not test a standalone treatment protocol or establish a causal effect for each relationship factor.
Scope: Association between alliance and outcomes in adult psychotherapy.
Recorded material under review
The existing notes below are retained separately from assessment records. These recorded claims await source checking, including study design, recommendations and numerical estimates.
Meta-analytic (thousands of studies synthesized)
Wampold & Imel (2015); Norcross & Lambert (2019)
Not a therapy but the framework most often invoked to explain why bona fide therapies with very different rationales produce such similar outcomes. Argues that what therapies share (alliance, empathy, expectations, ritual) accounts for more variance than what distinguishes them.

Assessment and precautions
Not applicable in the ordinary sense: this is a meta-framework describing what bona fide therapies share, not a treatment administered to a client, so it carries no client-side risk profile of its own. Contraindications belong to whichever specific therapy the clinician is actually delivering.
Blind spots
Can be used to dismiss the value of specific training, and becomes actively harmful when invoked to justify not learning the evidence-based protocols that some conditions require; '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)
Philosophical roots
Rosenzweig (common factors, 1936); Frank & Frank (Persuasion and Healing); Wampold (contextual model); Rogers (necessary and sufficient conditions); social psychology of healing

What is the 'Dodo Bird verdict' in psychotherapy?
Show answer
The finding that different bona fide therapies produce roughly equivalent outcomes, suggesting that common factors (alliance, empathy, expectations) matter more than specific techniques.
