Understanding Results

Formula

PHQ‑2 scoring is a simple sum of two items. Each question is answered for the last two weeks using four choices: Not at all (0), Several days (1), More than half the days (2), and Nearly every day (3). Your total equals Item 1 + Item 2, for a range of 0–6. No weights or multipliers are used.

Reference Ranges & Interpretation

A common interpretation is that totals under 3 are a negative screen and totals of 3 or more are a positive screen. A positive screen does not diagnose depression—it indicates that a more detailed questionnaire such as the PHQ‑9 may be helpful to understand symptom pattern and severity. Some settings prefer a more sensitive threshold of 2 or more. If your score is low but you still have concerns, you can still complete the PHQ‑9 or talk with a clinician.

Assumptions & Limitations

The PHQ‑2 is intentionally brief and cannot cover all areas of life. Results can shift with sleep, stress, illness, medications, or major events. The tool does not provide medical advice or an emergency response. If you ever feel unsafe or think about harming yourself, seek immediate help through local emergency services or established crisis lines in your region.

Use our PHQ-2 calculator to screen for depression in under a minute. Answer two questions, see a 0–6 score, and know when to follow up with the PHQ-9.

What is the PHQ‑2?

The PHQ‑2 is a two‑question screening tool that checks for core symptoms associated with depressed mood over the last two weeks. The items ask about little interest or pleasure in doing things and about feeling down, depressed, or hopeless. Each answer is scored from 0 to 3 based on frequency: Not at all (0), Several days (1), More than half the days (2), and Nearly every day (3). The two item scores are added for a total from 0 to 6. The PHQ‑2 is designed to be quick and practical. It is not a diagnosis, but it can signal when a longer questionnaire like the PHQ‑9 may be useful.

Many clinics use the PHQ‑2 during routine visits because it is fast, easy to repeat, and helps open a conversation. A higher score suggests that symptoms may be present more days than not, which can be a good reason to take a closer look at patterns, stressors, sleep, and daily routines.

In research and clinical settings, the PHQ‑2 has been studied as a front door to more comprehensive screens. While different studies report slightly different sensitivity and specificity at various cut points, the shared theme is consistent: it is a quick filter. When used as intended—as a starting point rather than a final word—it supports thoughtful next steps and more personalized decisions.

How the PHQ‑2 calculator works

This PHQ‑2 calculator mirrors the original scoring exactly. You select one option for each question, and the app adds the two values to show your total (0–6). Once both items are answered, you immediately see whether your screen is considered positive or negative and a short note about common next steps, such as completing the nine‑item PHQ‑9 depression calculator for a more complete view. The layout is phone‑first: large tap targets, clear labels, and readable results without scrolling sideways.

Your answers are not saved on our servers. If you want to keep a copy, you can use the built‑in “Copy summary” button or take a screenshot. Privacy is one of our core design principles across the site.

We designed the interaction to be simple on purpose: two questions, one total, and a short explanation in plain language. There are no distracting charts or widgets because the intent is clarity. If you decide to complete the PHQ‑9 afterward, you will see a little more detail, including a severity band and space to reflect on how much the symptoms make daily life harder.

How do you score and interpret PHQ‑2 cut points?

Your PHQ‑2 total is the sum of your two answers. The most common cut point is a total of 3 or higher, which is often called a positive screen. A positive screen means you might benefit from a fuller look at symptoms using a tool like the PHQ‑9, and that it could be useful to discuss how you have been feeling with a licensed professional. Some settings use a more sensitive threshold of 2 or higher, which can catch more people with possible symptoms at the cost of more false positives. Either approach treats the PHQ‑2 as a quick indicator that guides the next step rather than a final answer.

Remember, a negative screen (for example, 0–2) does not rule out every concern. If you feel that your mood, motivation, or energy are changing in a way that affects daily life, you can still take the PHQ‑9 now or talk with a clinician. Screening tools are meant to be helpful prompts, not gatekeepers.

One practical way to think about cut points is trade‑offs. A higher threshold (like 3) reduces false positives but may miss some people who would appreciate a fuller check‑in. A lower threshold (like 2) catches more possible cases but increases the number of positive screens that are ultimately not related to clinical depression. There is no universal right answer; the best choice depends on your setting, goals, and tolerance for follow‑up.

PHQ‑2 vs. PHQ‑9: when should you use each?

The PHQ‑2 and PHQ‑9 are part of the same family. The PHQ‑2 is the ultra‑brief screener; the PHQ‑9 expands the scope to nine items that cover sleep, appetite, energy, concentration, movement changes, and thoughts of self‑harm in addition to low mood and reduced interest. In many workflows, the PHQ‑2 is used first because it takes only a few seconds. If the PHQ‑2 is positive—or if someone prefers a deeper snapshot regardless of the two‑item score—then the next step is the PHQ‑9.

Sometimes people arrive with mixed symptoms where anxiety feels stronger than low mood. In those cases, brief tools focused on anxious feelings can be helpful too. You can try the two‑item GAD‑2 anxiety calculator or the seven‑itemGAD‑7 anxiety calculator. If you want a combined four‑item snapshot that shows both anxiety and depression subscores, check the PHQ‑4 mental health calculator.

Choosing between these tools is not about passing a test. It is about finding the right level of detail for the moment. If you are looking for a quick nudge toward reflection, the PHQ‑2 makes sense. If you want more nuance and a severity band, the PHQ‑9 is the stronger option. You can also use both: start with the PHQ‑2 and move to the PHQ‑9 right away.

What does a positive PHQ‑2 screen mean?

A positive PHQ‑2 usually means your answers suggest low mood or loss of interest has been present several days or more in the last two weeks. It does not diagnose a condition. Instead, it is a prompt to consider completing a more detailed questionnaire like thePHQ‑9 and to reflect on how symptoms affect work, school, home, or relationships. If symptoms are making life harder or less enjoyable, you might also consider talking with a licensed mental health professional.

If your screen is positive and sleep has been off, tools like the sleep calculator or theinsomnia calculator can help you plan a steadier schedule. Small changes to sleep timing, routines, and light exposure can support mood over time.

A positive screen can also be a cue to check in with supportive habits: time outdoors, movement, social connection, and manageable steps at work or school. None of these guarantee a change in mood, yet they often provide a helpful base while you consider more formal options. If you choose to speak with a professional, bringing your recent PHQ‑2 or PHQ‑9 results can make the conversation more concrete.

How should you track PHQ‑2 scores over time?

Many people take the PHQ‑2 weekly or monthly to notice patterns. It works best when you answer under similar conditions—for example, the same day of the week and similar time of day. If you start a new routine like a short walk, a sleep schedule, relaxation practice, or a conversation with a counselor, you can compare scores in the following weeks to see whether things feel different. Try to pair the PHQ‑2 with notes about sleep, caffeine, alcohol, stressors, or life events so changes make sense in context.

If tracking feels helpful, you may also like our meditation timer for short breathing breaks or thestress calculator to reflect on pressure from work or life. None of these tools are medical care, but they can support awareness and small, practical steps.

When you look back at your own notes, consider patterns rather than single measurements. A one‑off higher score after an exhausting week might not mean much by itself. A steady upward trend over several weeks, especially if it matches tough mornings, reduced interest in usual activities, or changes in sleep and appetite, might signal that a deeper look would be useful.

What are the limitations and good practices?

The PHQ‑2 is brief by design. It checks only two symptom areas and cannot capture the full picture of your life, history, environment, or strengths. Results can also shift with short‑term events: a rough week at work, a cold, a family stressor, jet lag, or poor sleep. Because it uses a two‑week window, today’s score may look different next week. That does not make the tool unreliable—it simply reflects that mood is responsive to daily reality.

Good practices include answering honestly without overthinking, using the same time frame each time you check, and avoiding a score‑chasing mindset. The goal is to notice patterns, not to “get a perfect number.” If you are curious about a broader view, the nine‑item PHQ‑9 adds helpful detail.

Another limitation is that brief screens do not account for culture, identity, or context. The same score can arise from very different stories. When in doubt, consider a conversation with someone who can understand your situation and values. A caring discussion with a clinician or a trusted person often helps make sense of numbers.

Practical examples and scenarios

Example 1: You answer 1 on the first item and 1 on the second (total 2). That is a negative screen with the common ≥3 cut point. You have noticed a few low‑energy days but feel okay overall. You decide to keep an eye on sleep and mornings for two weeks and recheck. You bookmark the sleep calculator to help you plan consistent bedtimes.

Example 2: You answer 2 and 1 (total 3). That is a positive screen. You complete the PHQ‑9 and notice your total falls in the moderate range, with sleep and appetite changes standing out. You decide to schedule a conversation with a clinician and also plan a few simple support steps this week: a short walk most days, a consistent wake up time, and a call with a friend.

Example 3: Your PHQ‑2 is 1 today, but last month it was 4 during a stressful period at work. The change lines up with a lighter workload and better rest. You feel more like yourself again. You keep your notes and plan to recheck monthly for a while so you can spot early signs if things start to drift.

Which tools pair well with the PHQ‑2?

The most direct pair is the PHQ‑9 depression calculator. If anxious feelings stand out, try the GAD‑2 or theGAD‑7. For a compact snapshot of both domains, use thePHQ‑4. If you are working on sleep routines, thesleep calculator and insomnia calculatorcan be a practical complement.

How to talk about your results

If you choose to share your results with a clinician or someone you trust, simple language works well. You might say: “I used a brief tool that checks for low mood. My score suggests a positive screen, and I’ve noticed mornings feel heavier and I enjoy hobbies less.” Concrete examples help: sleep shifts, appetite changes, trouble concentrating, or skipping usual activities.

If you are not sure what you want from the conversation, you can also lead with a goal such as: “I want to understand what this score might mean and whether there are small steps I can try.” Many people find it easier to start with what feels hardest right now rather than a long history. Bringing your PHQ‑2 or PHQ‑9 summary can keep the discussion focused and specific.

When should you seek help or urgent support?

If you are thinking about harming yourself or feel unsafe, seek immediate help from local emergency services or established crisis lines in your region. The PHQ‑2 is not a crisis tool and cannot provide emergency support. If your score is positive, if symptoms make daily life harder, or if you want a place to start, consider talking with a licensed professional who can listen, understand your context, and discuss options.

Common questions about accuracy and next steps

How accurate is a PHQ‑2 calculator for screening? It performs well as a brief screener when used as intended: to prompt a fuller look, not to make a diagnosis. A common approach is to treat totals of 3 or more as a positive screen and then complete the PHQ‑9. The nine‑item version provides a wider range of information, including sleep and energy changes, which helps interpret the big picture.

If your PHQ‑2 is negative but you still do not feel like yourself, a longer screen can still be useful. You know your experience best. Consider repeating the PHQ‑2 in a week, trying thePHQ‑4, or discussing how you are doing with someone you trust. Small, steady steps add up.
