What this topic is asking
Topic 5.5 covers how psychological disorders are treated. The College Board wants the major psychotherapies (psychodynamic, humanistic, behavioral, cognitive, and cognitive-behavioral), the biomedical treatments (drugs, ECT, TMS), and the formats and ethics of treatment.
Psychotherapies
Each major perspective from Topic 5.3 has a matching therapy:
- Psychodynamic (psychoanalysis): aims to bring unconscious conflicts into awareness, using free association, dream analysis, and interpretation of resistance and transference.
- Humanistic (person-centered, Rogers): uses unconditional positive regard, empathy, genuineness, and active listening to help clients grow and accept themselves.
- Behavioral: treats the symptom as a learned behavior. Systematic desensitization and exposure therapy treat phobias by pairing relaxation with gradual exposure to the feared stimulus (counterconditioning). Aversive conditioning pairs an unwanted behavior with discomfort. Token economies apply operant rewards for desired behavior.
- Cognitive: changes maladaptive thoughts (for example through cognitive restructuring or Beck's therapy for depression).
- Cognitive-behavioral therapy (CBT): combines cognitive restructuring with behavioral change; one of the most effective and widely used therapies.
Biomedical treatments
When biology is the target, treatments act directly on the brain and body:
- Drug therapies: antidepressants (often SSRIs, which raise serotonin activity), antianxiety drugs, antipsychotics (for schizophrenia), and mood stabilizers such as lithium for bipolar disorder.
- Electroconvulsive therapy (ECT): brief electrical stimulation of the brain under anesthesia, used for severe, treatment-resistant depression.
- Transcranial magnetic stimulation (TMS): a non-invasive technique using magnetic fields to stimulate brain regions, also used for depression.
- Psychosurgery (such as the historical lobotomy) is now rare.
Formats, ethics, and the eclectic approach
Therapy occurs in different formats: individual, group, family, and couples therapy. Many clinicians use an eclectic approach, drawing on whichever techniques best fit the client. Treatment is governed by ethical standards, including informed consent, confidentiality, and competence.
The organizing logic of this topic is that the treatment follows from how the disorder is explained, which ties it directly back to Topic 5.3. A psychodynamic view yields psychoanalysis; a behavioral view yields exposure and token economies; a cognitive view yields cognitive restructuring; a biological view yields drugs, ECT, and TMS. The exam frequently gives a technique and asks for the approach, or describes a disorder and asks which treatment fits, so the skill is to map each named technique to its parent perspective. Systematic desensitization (behavioral), free association (psychodynamic), unconditional positive regard (humanistic), and SSRIs (biomedical) are the highest-yield pairings. The eclectic approach and CBT show that, in practice, the best treatment often blends approaches, and the ethics material reminds you that therapy is a regulated, consent-based relationship.

AP 2024 (style)1 marksMultiple choice. A therapist treats a client's phobia by teaching relaxation and then gradually exposing the client to increasingly fear-provoking versions of the feared stimulus. This technique is best described as which of the following? (A) Free association (B) Systematic desensitization (C) Cognitive restructuring (D) A token economy (E) Electroconvulsive therapyShow worked answer →
The answer is (B) Systematic desensitization.
Systematic desensitization is a behavioral (counterconditioning) technique that pairs deep relaxation with a gradual hierarchy of fear-provoking stimuli, so the client learns to stay calm in the presence of the feared object. It is a form of exposure therapy.
(A) free association is a psychodynamic technique. (C) cognitive restructuring changes maladaptive thoughts. (D) a token economy uses operant rewards. (E) electroconvulsive therapy is a biomedical treatment for severe depression.
AP 2023 (style)5 marksConcept-application free-response question. A clinic offers several treatments. Explain how EACH of the following could be used: psychoanalysis, person-centered therapy, systematic desensitization, cognitive-behavioral therapy, and drug therapy.Show worked answer →
A 5-point concept-application FRQ; one point per term.
Psychoanalysis (1): a psychodynamic therapy using techniques like free association to bring unconscious conflicts into awareness.
Person-centered therapy (1): Rogers's humanistic therapy using unconditional positive regard, empathy, and active listening to support growth.
Systematic desensitization (1): a behavioral technique pairing relaxation with gradual exposure to a feared stimulus.
Cognitive-behavioral therapy (1): combining cognitive restructuring of maladaptive thoughts with behavioral change.
Drug therapy (1): biomedical treatment using medications (such as antidepressants or antipsychotics) to alter brain chemistry.
Markers reward each treatment being correctly defined AND tied to its therapeutic approach.
