What are the DSM-5 criteria for major depressive disorder?

The DSM-5 criteria for major depressive disorder require five or more of nine symptoms during the same two-week period, present most of the day, nearly every day. At least one must be depressed mood or loss of interest or pleasure. The symptoms must cause significant distress or impairment and not stem from a substance, a medical condition, or bipolar disorder.

If you are searching this question, you may be trying to make sense of a stretch of weeks that has felt heavier than usual, or a screening score that surprised you, or a change in someone you love. This article walks through the DSM-5 criteria in plain English, explains how a licensed clinician turns that list into a real evaluation, and covers what evidence-based treatment involves and when to reach out.

What the DSM-5 Is and Why the Criteria Matter

The DSM-5 is the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, published by the American Psychiatric Association. It is the reference clinicians across the United States use to define mental health conditions, including major depressive disorder (MDD), the clinical name for what most people simply call depression.

Depression is not the same as a bad week, grief after a loss, or the low mood that follows a disappointment. The criteria exist to draw that line consistently, and they describe a pattern, not a personality. The National Institute of Mental Health describes depression as a condition that affects how you feel, think, and handle daily activities such as sleeping, eating, and working (NIMH).

The Nine Symptoms in the DSM-5 Criteria for Major Depressive Disorder

The DSM-5 lists nine symptoms of a major depressive episode, and at least one of the first two must be present. Here is what each looks like in daily life, following the criteria as summarized by the American Psychiatric Association (APA) and the StatPearls clinical reference on the National Library of Medicine Bookshelf (StatPearls, 2025).

1. Depressed mood — feeling sad, empty, or hopeless most of the day, nearly every day. In teens, this can show up as irritability.
2. Loss of interest or pleasure — also called anhedonia. Activities that used to matter feel flat, across almost everything. We explore this in Anhedonia: When Nothing Feels Good Anymore.
3. Significant appetite or weight change — eating noticeably more or less, or a weight change you were not trying for.
4. Sleep disturbance — insomnia or sleeping far more than usual, nearly every day.
5. Psychomotor agitation or slowing — restlessness, or slowed movement and speech, that other people can observe.
6. Fatigue or loss of energy — exhaustion that rest does not fix, so small tasks feel enormous.
7. Feelings of worthlessness or excessive guilt — harsh self-judgment that is out of proportion to events.
8. Trouble concentrating or making decisions — foggy thinking, rereading the same paragraph, agonizing over minor choices.
9. Recurrent thoughts of death or suicide — from passive thoughts that life is not worth living to specific plans. Any thought in this category deserves attention right away.

If you are having thoughts of suicide or self-harm, please reach out now. Call or text 988 (Suicide & Crisis Lifeline) any time, day or night. In Georgia, you can also call the Georgia Crisis & Access Line at 1-800-715-4225. If you or someone you know is in immediate danger, call 911 or go to your nearest emergency room.

Notice how physical this list is. Depression does not always look like sadness. For many adults it shows up as irritability, foggy thinking, and a body that feels heavy, so that climbing the stairs feels like wading through wet concrete. One way to picture it: a phone running on 1% battery with dozens of apps open in the background, quietly draining power you cannot see. Those are symptoms of a system under strain, not character flaws.

The Five-of-Nine Rule and the Two-Week Rule

The criteria work like a simple formula: a two-week time frame, plus at least five of nine symptoms with one from the core pair, minus any substance or medical explanation, and the result has to be getting in the way of your life.

Five of nine. You do not need all nine symptoms. Five is the threshold, in any combination, as long as one is depressed mood or loss of interest. This is why two people with depression can look very different: one sleeps twelve hours a day, another is awake at 3 a.m. with no appetite. Our short answer to what the 5 symptoms of major depressive disorder are explains why there is no fixed set.

Two weeks. The symptoms must be present together for at least two weeks and represent a change from how you were functioning before. NIMH describes the same standard: symptoms most of the day, nearly every day, for at least two weeks (NIMH). A terrible weekend after bad news does not meet the duration rule. Two straight weeks of feeling flat and dragging yourself through everything might. Think of it this way: a rough weekend is passing bad weather. Two straight weeks is a change in the climate.

"Most of the day, nearly every day." This phrase separates a persistent pattern from the normal ups and downs of being human. Thoughts of death or suicide are the exception: the criteria describe them as recurrent rather than daily, and even one serious episode of suicidal thinking is a reason to get help immediately.

The Impairment Requirement: It Has to Affect Your Life

Meeting the symptom count is necessary but not sufficient. The DSM-5 also requires that the symptoms cause clinically significant distress or impairment in social, work, or other important areas of life. In everyday terms, the symptoms have to be getting in the way: calling out of work, falling behind in classes, pulling away from people, or struggling with basic routines.

This is the part people with so-called high-functioning depression tend to doubt. If you are still showing up, does it count? Distress counts. The criteria say distress or impairment, not both. Suffering quietly while keeping every plate spinning is still suffering, and it is still worth evaluating.

Rule-Outs: What Has to Be Excluded First

The DSM-5 criteria for major depressive disorder include several exclusions, and a clinician works through them before confirming the diagnosis.

Substances and medications. The episode cannot be better explained by the effects of a substance. Alcohol, some recreational drugs, and certain prescribed medications can all produce depression-like symptoms. This is a question of cause, not a judgment.

Medical conditions. NIMH notes that certain medications and medical conditions, such as viral illnesses or thyroid disorders, can cause the same symptoms as depression, which is why a provider may order a physical exam and lab tests (NIMH). The American Psychiatric Association likewise recommends screening for conditions that mimic depression, including hormonal imbalances and vitamin deficiencies (APA).

No history of mania or hypomania. If you have ever had a manic or hypomanic episode (a distinct period of unusually elevated or irritable mood, racing energy, and much less need for sleep), the diagnosis shifts toward a bipolar spectrum disorder. The depressive episodes can look identical; the history changes the treatment plan. See Bipolar II Disorder: The Most Misdiagnosed Mood Disorder.

A note on grief. Grief after a major loss can bring deep sadness, poor sleep, and appetite changes without being depression. The two can also occur together, and a clinician uses history, judgment, and cultural context to tell them apart.

Specifiers: The Details After the Diagnosis

Once the criteria are met, clinicians add specifiers, which describe the episode in more detail and help shape the plan. In brief:

• Severity — mild, moderate, or severe, based on symptom count, intensity, and impairment.
• Single episode or recurrent — a first episode, or one of several.
• Features — with anxious distress, melancholic features, atypical features, psychotic features, or catatonia.
• Timing — with peripartum onset (pregnancy and the weeks after delivery) or with seasonal pattern.

Specifiers do not change whether you have depression. They tell the clinician which kind of help to prioritize.

Why a Checklist Is Not a Diagnosis

The nine criteria look a lot like the questions on an online depression quiz, and that is on purpose. The PHQ-9, one of the most widely used screening tools, asks about each of the nine symptoms over the past two weeks. But a screening score is a signal, not a verdict. A checklist cannot rule out a thyroid problem, ask about a hypomanic episode you never thought was significant, or tell whether your low mood is grief, an adjustment to a major life change, or a persistent depressive disorder that has quietly lasted for years. It is a bit like a car that will not start: a dead battery and a failing alternator look identical from the driver's seat, and you need a mechanic to tell them apart.

Self-diagnosis in either direction is risky. Some people score high and assume the worst; others score below the cutoff and dismiss real suffering. Only a licensed clinician can diagnose major depressive disorder, and they do it by looking at the whole person.

What a Depression Evaluation Actually Looks Like

A depression evaluation with a licensed therapist is a conversation, not a test you can fail. It usually moves through a few stages:

1. Your story first. What brought you in, when things changed, and what a typical day looks like now compared with six months ago.
2. Symptom review. The clinician walks through the nine criteria, often starting from a PHQ-9, and asks about duration, frequency, and impact.
3. Safety check. Expect direct, calm questions about thoughts of death or suicide. This is standard, and answering honestly is the safest thing you can do.
4. History and rule-outs. Past periods of unusually high energy or little sleep, substance use, medical conditions, medications, and family history.
5. A shared plan. You should leave understanding what the clinician is seeing and what they recommend, whether therapy, a medical workup, a referral to a prescriber, or some combination.

At Coping & Healing Counseling, this conversation happens by secure video from anywhere in Georgia, with licensed clinicians (LCSWs, LPCs, and LMFTs) who evaluate and treat depression every week.

Evidence-Based Therapy for Major Depressive Disorder

Several psychotherapies have strong research support for depression. The American Psychological Association's clinical practice guideline recommends a set of psychotherapies for adults, including behavioral therapy, cognitive behavioral therapy, and interpersonal psychotherapy (APA, 2019).

Cognitive behavioral therapy (CBT) works on the loop between thoughts, feelings, and actions. Depression generates harsh, absolute thoughts ("I always ruin things"), and CBT teaches you to notice those patterns, test them, and respond differently. NIMH lists CBT among the therapies with evidence for depression (NIMH).

Behavioral activation (BA) works from the outside in. Depression shrinks your world: you stop doing things, which removes pleasure and meaning, which deepens the depression. BA helps you schedule small, specific actions, such as a ten-minute walk or a five-minute phone call, and do them before motivation returns, because waiting until you feel like it can mean waiting forever. A meta-analysis of 26 randomized trials found behavioral activation more effective than control conditions for depressive symptoms (Ekers et al., 2014).

Interpersonal therapy (IPT) focuses on the relationships and role changes tied to a depressive episode, such as grief, conflict, a major transition, or isolation. It is time-limited and structured, and NIMH names it alongside CBT as an evidence-based option (NIMH).

None of these approaches promise a particular result, and no honest clinician will. What the research supports is that many people experience meaningful improvement with structured therapy, with progress building over weeks rather than days.

What about medication? For some people, medication is part of the plan. That decision belongs to a prescriber, such as a psychiatrist, psychiatric nurse practitioner, or primary care provider, and therapy can continue either way.

We dove deeper into this on our YouTube channel. Watch the full episode — about 19 minutes — for a plain-English walk-through of the two-week rule, the physical symptoms people miss (heaviness, fog, irritability), why thyroid problems and substances have to be ruled out, and how CBT, behavioral activation, and interpersonal therapy are built for someone running on empty.

What You Can Do This Week

• Track two weeks honestly. Jot down mood, sleep, appetite, and energy each evening. Patterns are easier to see on paper, and the notes are useful in a first session.
• Take a validated screener. Our free depression test is built on the same nine criteria. Treat the result as information, not a verdict.
• Tell one person. Depression isolates. Naming it to someone you trust often loosens its grip a little and makes the next step easier.
• Pick one small activity and do it anyway. Borrow from behavioral activation: a ten-minute walk, one text message, one chore. Action can come before motivation.
• Look again at someone who seems "difficult." If a friend, coworker, or family member has been unusually irritable, distant, or hard to please for weeks on end, you may be seeing unrecognized distress rather than a change in character. A gentle check-in costs little.

Frequently Asked Questions

How many symptoms do you need for major depressive disorder?

You need at least five of the nine DSM-5 symptoms during the same two-week period, and at least one must be depressed mood or loss of interest or pleasure. The symptoms must cause significant distress or impairment and must not be better explained by a substance, a medical condition, or a history of mania or hypomania.

Can you have major depressive disorder without feeling sad?

Yes. The DSM-5 allows the core symptom to be loss of interest or pleasure rather than depressed mood. Some people describe feeling numb, flat, or irritable instead of sad. If at least five symptoms, including loss of interest, are present for two weeks and cause distress or impairment, the criteria can still be met.

Is two weeks really enough to be diagnosed with depression?

Two weeks is the minimum duration in the DSM-5 criteria, not the typical length of an episode. Many people have been struggling for months before they seek help. The two-week rule exists to separate a persistent pattern of symptoms from a short, understandable reaction to a hard event or a difficult few days.

What if I have some symptoms but not five?

Fewer than five symptoms does not mean nothing is wrong. You might be experiencing a milder depressive condition, an adjustment to a stressor, persistent depressive disorder, or the early signs of an episode. Distress at any level is a good enough reason to talk with a therapist, who can help you understand what is happening and what might help.

When to Seek Professional Help

If you recognized yourself in five or more of the symptoms above, and they have been with you most days for two weeks or longer, that is a reason to talk with a licensed clinician. You do not need to be certain, and you do not need to be in crisis. Wanting to feel better is enough.

A good first step is our Free depression test, a brief screener built on the same nine criteria. Bring the result to a first session, or simply reach out.
