Nonmaleficence in AP Psychology

In AP Psychology, nonmaleficence is the APA ethical principle that psychologists in clinical or therapeutic situations must avoid causing harm to their clients. It is one of the principles, along with fidelity, integrity, and respect for people's rights and dignity, listed under Topic 5.5.

What is nonmaleficence?

Nonmaleficence is the "do no harm" rule of psychology. The APA requires psychologists working in clinical or therapeutic settings to avoid causing harm to the people they treat. The word breaks down simply. Non means not, and maleficence means doing harm. So it literally means "not doing harm."

In the CED, nonmaleficence sits alongside fidelity, integrity, and respect for people's rights and dignity as the ethical principles therapists must follow (5.5.B). In practice, it means a therapist weighs the risks of a treatment before using it. If a client becomes severely distressed, the therapist stops or adjusts. It also means the therapist doesn't keep pushing a technique that is hurting the person, even if it is supposed to work eventually.

Why nonmaleficence matters in AP® Psychology

Nonmaleficence lives in Unit 5: Mental and Physical Health, in Topic 5.5 Treatment of Psychological Disorders. It directly supports learning objective 5.5.B, which asks you to describe ethical principles in the treatment of psychological disorders. It also gives you a lens for the rest of the topic. When 5.5.F lists medication side effects like tardive dyskinesia, or invasive options like psychosurgery and ECT, nonmaleficence is the reason those risks matter. The exam likes to drop you into a scenario and ask which ethical line was crossed, so this term is less about memorizing a definition and more about spotting harm in a situation.

How nonmaleficence connects across the course

Biological Treatments and Side Effects (Unit 5)

Psychoactive medications can cause side effects like tardive dyskinesia, a movement disorder tied to dopamine regulation. Nonmaleficence is why a psychiatrist has to weigh whether a drug's benefits are worth that risk. The side effect is the harm, and the ethical principle is the reason to care about it.

Psychosurgery and the Lobotomy (Unit 5)

The lobotomy is the classic cautionary tale in Topic 5.5. It was an invasive procedure that caused serious, permanent damage. Think of it as nonmaleficence's "what not to do" example. That history is why surgical options today are rare and treated as a last resort.

Aversion Therapy and Exposure Therapy (Unit 5)

Some behavioral techniques work by making the client uncomfortable on purpose, like pairing a behavior with something unpleasant or facing a feared object. Nonmaleficence sets the limit. Planned, controlled discomfort is fine. Severe distress that the client wants to stop is not, and continuing past that point is a violation.

Cultural Humility and Evidence-Based Treatment (Unit 5)

The CED says therapists should use evidence-based interventions and show cultural humility. Both protect clients from harm. A treatment with no research behind it, or one that ignores a client's cultural view of mental health, can end up hurting the person it was meant to help.

Is nonmaleficence on the AP® Psychology exam?

Expect scenario-based MCQs. A stem describes a therapist or researcher doing something, and you pick the ethical principle involved. Typical setups include:

• A psychologist continues exposure therapy even though participants report severe emotional distress and ask to stop. That is a harm problem, so nonmaleficence is in play.
• A placebo-controlled medication study leaves some depressed participants untreated. Ask yourself whether anyone is being put at risk.
• A therapist adapts treatment for a client whose culture views mental health differently. Ask whether the change protects the client or reflects respect for their dignity.

The skill is matching the scenario to the right principle. Nonmaleficence is about harm. If the question is really about telling the client what they're signing up for (like explaining that a treatment is experimental), the answer usually points toward informed consent and respect for people's rights, not nonmaleficence. No released FRQ has used this term verbatim. Still, being able to explain why a treatment choice is or isn't ethical gives you a strong way to analyze a therapy scenario in a free-response answer.

Nonmaleficence vs Beneficence

These two get mixed up because the APA pairs them in one principle ("Beneficence and Nonmaleficence"). Beneficence means actively doing good for the client. Nonmaleficence means avoiding harm. A simple way to remember it is that beneficence is the gas pedal and nonmaleficence is the brake. On AP scenarios, if the problem is that someone got hurt or was put at risk, think nonmaleficence.

Key things to remember about nonmaleficence

• Nonmaleficence is the APA ethical principle that psychologists must avoid causing harm to clients in clinical or therapeutic situations.

• The CED lists nonmaleficence with fidelity, integrity, and respect for people's rights and dignity under learning objective 5.5.B.

• Continuing a therapy after a client reports severe distress and asks to stop is a textbook nonmaleficence violation.

• Medication side effects like tardive dyskinesia and the history of the lobotomy show why therapists must weigh a treatment's risks against its benefits.

• If a scenario is mainly about explaining a treatment to the client beforehand, the answer is usually informed consent or respect for rights rather than nonmaleficence.

Frequently asked questions about nonmaleficence

What is nonmaleficence in AP Psychology?

Nonmaleficence is the APA ethical principle that psychologists must avoid harming the clients they treat. It appears in Topic 5.5 under learning objective 5.5.B, alongside fidelity, integrity, and respect for people's rights and dignity.

Does nonmaleficence mean therapy can never make a client uncomfortable?

No. Treatments like exposure therapy involve planned, controlled discomfort and can still be ethical. The violation happens when a therapist causes unnecessary or severe harm, such as continuing treatment after a client is in serious distress and asks to stop.

What is the difference between nonmaleficence and beneficence?

Beneficence means actively doing good for the client, while nonmaleficence means avoiding harm. The APA groups them into one principle, but on the AP exam a scenario about someone being hurt or put at risk points to nonmaleficence.

Is explaining an experimental treatment to a client an example of nonmaleficence?

Not usually. Telling a client that a treatment has limited research support before starting is mainly about informed consent and respect for the client's rights. Nonmaleficence would come in if the treatment itself puts the client at risk of harm.

How do medication side effects connect to nonmaleficence?

Psychoactive drugs can cause side effects like tardive dyskinesia, a movement disorder linked to dopamine regulation. Nonmaleficence requires clinicians to weigh that risk of harm against the medication's benefits before and during treatment.
