A decision before an answer
- People often improve with no treatment at all, so a before-and-after gain is not yet evidence that a therapy worked.
- Your goal: Match major therapy families to their proposed mechanisms.
Learn the families by mechanism
- Each therapy family proposes a mechanism. Psychodynamic work targets unconscious conflict and early relationships, using transference; object-relations variants emphasise early relationships in particular. Behavioural treatment applies learning principles: systematic desensitisation traditionally pairs a graded fear hierarchy with relaxation (counterconditioning), while exposure approaches need not use relaxation pairing.
- Cognitive-behavioural therapy identifies and tests distorted thoughts and adds behavioural activation. Person-centred work offers empathy, unconditional positive regard and congruence; Gestalt work stresses the here and now. Biological treatment includes medication and, for severe depression, electroconvulsive therapy.
A client with a specific phobia is taught relaxation and then works through a graduated hierarchy of feared situations. This is:

Exposure paired with relaxation is counterconditioning, a behavioural method.
Match technique to presentation
- Match technique to mechanism and presentation: specific phobia points to graduated exposure; obsessive-compulsive disorder to exposure with response prevention; depression to cognitive restructuring plus activity scheduling.
- A therapist rooted in object relations will emphasise early life relationships, not medication or cognitive distortion lists.
The strongest design for concluding that a new therapy causes improvement is:

Only a controlled comparison separates treatment gain from spontaneous remission and regression to the mean.
Demand controlled comparisons
- Outcome claims need controls because of spontaneous remission and regression to the mean: people seek help at their worst and improve anyway. A randomised controlled trial with a waitlist or placebo comparison separates treatment gain from natural course.
- Efficacy is performance under controlled conditions; effectiveness is performance in ordinary practice. Meta-analysis pools trials for a more stable estimate.
A therapist rooted in object relations theory emphasises early life relationships. A phobia treated by a relaxation-paired hierarchy is counterconditioning. A treated group improving from pre-test to post-test shows change, not efficacy: without a control, regression to the mean and spontaneous remission remain open.
Systematic desensitisation pairs graduated exposure with ____.

The incompatible relaxed response counterconditions the fear response.
Weigh common factors
- When bona fide therapies show comparable mean outcomes, the common-factors hypothesis credits shared ingredients such as the working alliance, expectancy and empathy rather than branded techniques.
- Comparable means do not prove identical mechanisms, and a single trial cannot settle the question either way.
Inferring causation from a before-and-after gain without a control, or treating comparable means as proof of identical mechanisms.

Comparable mean outcomes across bona fide therapies prove that all therapies share identical mechanisms.

The common-factors hypothesis credits shared ingredients; equal means do not establish equal mechanisms.
Keep the distinctions
- counterconditioning 对抗性条件作用 — Replacing a conditioned response by pairing the stimulus with an incompatible response such as relaxation.
- common factors 共同因素 — Ingredients shared across therapies, such as alliance and expectancy, proposed to explain comparable outcomes.
- Match major therapy families to their proposed mechanisms.
- Evaluate treatment-outcome evidence against appropriate controls.
- Distinguish efficacy, effectiveness and common-factor claims.
