Depression in AP Psychology

In AP Psychology, depression refers to depressive disorders: conditions marked by a sad, empty, or irritable mood plus physical and cognitive changes that impair daily functioning. The two in scope are major depressive disorder and persistent depressive disorder.

What is Depression?

Depression isn't just feeling sad after a bad week. In AP Psych, it means a depressive disorder. That's a sad, empty, or irritable mood that comes with physical and cognitive changes (think sleep, appetite, energy, concentration, self-worth) and gets in the way of a person's ability to function. Losing interest in things you used to enjoy is a classic sign.

The CED puts two depressive disorders in scope. Major depressive disorder (MDD) involves intense depressive episodes. Persistent depressive disorder (PDD), often called dysthymia, is a lower-grade depressed mood that hangs on for years. For causes, the CED wants you to think broadly. Depression can come from biological, genetic, social, cultural, behavioral, or cognitive sources. Basically, it's a textbook case for the biopsychosocial approach. No single cause explains it, so you should be ready to name several.

Why Depression matters in AP® Psychology

Depression lives in Unit 5: Mental and Physical Health, under Topic 5.4 Selection of Categories of Psychological Disorders. It directly supports AP Psych 5.4.C, which asks you to describe the symptoms and possible causes of selected depressive disorders. It also anchors AP Psych 5.4.D, because bipolar disorders are defined by periods of mania and periods of depression. If you don't know what a depressive episode looks like, you can't explain bipolar either. Depression also shows up a lot in scenario questions. Its list of possible causes (biological through cognitive) makes it a natural fit for questions about applying different psychological perspectives to one disorder.

How Depression connects across the course

Major Depressive Disorder and Dysthymia (Unit 5)

These are the two depressive disorders the CED actually tests. A useful way to picture it is that MDD is a deep, heavy storm and dysthymia (persistent depressive disorder) is a gray drizzle that won't stop for years. Both count as 'depression,' so exam questions push you to tell them apart by intensity and duration.

Bipolar I and Bipolar II Disorders (Unit 5)

Bipolar disorders are depression plus mania, cycling back and forth. The key is that a depressive episode alone points to a depressive disorder, while any history of mania or hypomania moves the diagnosis into the bipolar category. Depression is half of what bipolar is, so knowing it well makes 5.4.D much easier.

Antidepressants (Unit 5)

The biological explanation of depression and the biological treatment for it are two sides of the same coin. If a cause is about brain chemistry, a drug that changes brain chemistry is the matching fix. Linking cause to treatment is a strong move on free-response questions.

Anxiety Disorders (Unit 5)

Anxiety disorders and depressive disorders sit side by side in Topic 5.4, and both list biological, cognitive, and behavioral causes. The difference to keep straight is that anxiety disorders center on excessive fear or worry, while depressive disorders center on sad, empty, or irritable mood and lost interest.

Is Depression on the AP® Psychology exam?

On multiple-choice questions, depression usually shows up inside a clinical scenario. You get a client's symptoms and timeline, and you have to pick the right diagnosis. A common setup describes someone feeling 'down' most days for years with low self-esteem and hopelessness, but never meeting full criteria for major depression. That points to persistent depressive disorder, not MDD. Other questions test causes. For example, you might need to pick the finding that best supports a biological explanation, like the inflammatory hypothesis of depression. Bipolar questions also lean on depression, asking which symptom pattern does or doesn't fit Bipolar II.

On the free-response side, depression-related content has appeared in released SAQs, including 2021 SAQ Q1 (the Malia research-paper scenario) and 2023 SAQ Q1. What you need to DO is apply the concept to the specific person in the prompt. Name the symptom or cause, then explain how it shows up in that scenario. Just defining depression won't earn the point.

Depression vs Major Depressive Disorder vs. Persistent Depressive Disorder (Dysthymia)

Both are depressive disorders, so it's easy to mix them up. Major depressive disorder involves intense depressive episodes that fully meet the criteria for major depression. Persistent depressive disorder is milder but chronic, with a depressed mood that lasts for years without hitting full MDD criteria. On the exam, look at the timeline and intensity. 'Severe and episodic' points to MDD. 'Long-lasting, lower-grade, never quite major' points to dysthymia.

Key things to remember about Depression

• Depressive disorders involve a sad, empty, or irritable mood plus physical and cognitive changes that interfere with a person's ability to function.

• The two depressive disorders in scope for AP Psychology are major depressive disorder and persistent depressive disorder (dysthymia).

• Possible causes of depression can be biological, genetic, social, cultural, behavioral, or cognitive, so be ready to explain more than one.

• Persistent depressive disorder is chronic and lower-grade, while major depressive disorder involves more intense episodes.

• If a scenario includes any history of mania alongside depression, the diagnosis shifts to a bipolar disorder rather than a depressive disorder.

• On free-response questions, you earn points by applying depression's symptoms or causes to the specific person in the prompt, not by just defining it.

Frequently asked questions about Depression

What is depression in AP Psychology?

In AP Psych, depression refers to depressive disorders, which involve a sad, empty, or irritable mood plus physical and cognitive changes that impair functioning. It falls under Topic 5.4 and learning objective AP Psych 5.4.C.

Is feeling sad the same as having depression?

No. Ordinary sadness is a normal reaction to life events. A depressive disorder involves a persistent mood change plus physical and cognitive symptoms that actually get in the way of daily functioning.

How is major depressive disorder different from dysthymia?

Major depressive disorder involves intense depressive episodes that meet full criteria for major depression. Dysthymia (persistent depressive disorder) is a milder depressed mood that lasts for years, like the practice scenario of a client feeling 'down' most days for three years without ever meeting full MDD criteria.

Is bipolar disorder a type of depression?

No. Bipolar disorders are their own category in the CED. They include periods of depression, but what defines them is that those periods alternate with mania, which depressive disorders never include.

What causes depression according to the AP Psych CED?

The CED lists biological, genetic, social, cultural, behavioral, and cognitive sources as possible causes. One biological example the exam can test is the inflammatory hypothesis, which links depression to inflammation in the body.
