Depression symptoms often arrive as a pattern rather than one isolated feeling. Mood, energy, sleep, appetite, concentration, self-criticism, interest, and outlook can shift together, and a person trying to explain the last few weeks may remember the worst day, the most recent day, or the symptom that feels easiest to name. A structured inventory gives that experience a consistent shape so the same time window and the same symptom topics are considered each time.

The Beck Depression Inventory-II, commonly shortened to BDI-II, is a 21-item self-report measure for depressive symptom severity. It uses a two-week recall window, and each item is rated from 0 to 3 by intensity. The item scores are added into one total from 0 to 63, then read against minimal, mild, moderate, and severe ranges. Higher totals usually mean heavier current symptom burden, but the number still needs context from safety, daily function, medical issues, medication effects, grief, trauma, substance use, sleep disruption, and the setting in which the inventory was completed.

Recall window
The same recent two-week period should guide every answer.
Item score
Each symptom topic contributes 0, 1, 2, or 3 points.
Total score
The 21 item scores sum to a 0 to 63 depression-symptom total.
Severity band
The total is compared with published BDI-II cutoffs.
Item 9
The suicidal thoughts or wishes item needs separate attention even when the total is not high.

Severity bands are signposts, not diagnoses. A score near a cutoff can feel very different from a score in the middle of the same range, and two people with the same total may have different main concerns. One person may score through fatigue and concentration difficulty, while another may score through guilt, pessimism, and self-dislike. Looking at the highest-scored items prevents the total from hiding the symptom areas that need the most careful review.

Two-week BDI-II answers flow from 21 item ratings to a total score, severity band, cutoff context, and separate Item 9 review.

BDI-II results are most useful when they lead to a clearer conversation, not when they are treated as proof by themselves. The inventory does not explain the cause of symptoms, decide treatment, or replace a licensed assessment. It also does not make suicidal thoughts safer because the total is low. If self-harm thoughts are present, active, specific, or hard to dismiss, contact emergency services, a crisis line, or a trusted person who can stay with you. In the United States, calling or texting 988 connects to crisis support.

A careful BDI-II reading keeps three facts together: the total score, the symptom pattern behind that total, and the safety context. That combination is more useful than a single label when preparing for counseling, primary care, psychiatric care, or a repeat check-in.

How to Use This Tool:

Answer every item from the same recent two-week period. The report appears after all 21 item ratings are complete.

  1. Select Start BDI-II assessment to open the item-by-item flow.
  2. For each symptom item, choose one response from 0 - Not at all, 1 - Mild, 2 - Moderate, or 3 - Severe. The item help text keeps the two-week time frame visible while you answer.
  3. Use the progress bar and question navigator to find missing answers. If the progress count is still below 21/21 answered, the final score, severity band, and report will not appear yet.
  4. Read the completed summary first: Total score, Overall lane, Cutoff context, Support urgency, and the Item 9 badge carry the most important first-pass meaning.
  5. Review Score lane dial, Current score lane and cutoff context, Highest-scored driver items, and Higher-scored items and lower anchors to see which symptoms shaped the total.
  6. Use Suggested next steps as a plain-language follow-up prompt. If Item 9 is above zero, treat the support note as more important than the overall severity word.
  7. Copy or export the Answer review only when you are comfortable sharing sensitive symptom answers. A copied result link can preserve the answer pattern in the URL.

Interpreting Results:

The Total score is the main BDI-II result, but the safest reading also checks Item 9, Support urgency, the Cutoff context, and the highest-scored items. A low total can still matter when suicidal thoughts are present, daily function is slipping, or one symptom area is driving most of the score. A high total suggests a stronger current depression signal, not a stand-alone diagnosis.

  • 0 to 13, Minimal: lower current symptom burden on this inventory, while persistent symptoms still deserve attention.
  • 14 to 19, Mild: noticeable symptoms, especially important when the cutoff context is close to 20.
  • 20 to 28, Moderate: direct clinical follow-up is commonly reasonable.
  • 29 to 63, Severe: prompt clinical review is generally warranted.

The Top area and Highest-scored driver items help explain why the total landed where it did. Cognitive and outlook items point toward thoughts, guilt, pessimism, and worthlessness. Self-view and engagement items include self-dislike, suicidal thoughts or wishes, crying, agitation, withdrawal, irritability, and sex interest. Energy and body rhythm items include energy loss, sleep change, appetite change, concentration difficulty, and fatigue.

If the output feels wrong, verify the Answer review before acting on the band. Look for accidental clicks, a missing item, answers based on different weeks, or a response chosen for one extreme day rather than the whole recall window.

Technical Details:

BDI-II scoring is additive. Each of the 21 symptom items contributes one integer from 0 to 3, and no item is reverse-scored. That makes the total easy to audit: every point in the final score comes directly from an endorsed item, and the maximum possible total is 21 items multiplied by 3 points.

The two-week recall window is part of the measurement. Ratings based on a single bad day, a lifetime pattern, or an older episode can change the meaning of the total because the published bands assume recent symptom severity. Comparisons across repeated BDI-II runs are strongest when the same instrument, recall window, and answering conditions are kept as similar as possible.

Formula Core

The BDI-II total is the sum of all answered item scores. A final total is shown only after all 21 items have valid scores.

BDI-II total = ∑ i=1 21 qi 0 ≤ qi ≤ 3

For example, if the 21 item scores add to 24, the Total score is 24/63. That lands in the moderate band because 24 is greater than or equal to 20 and less than or equal to 28.

Scoring element Rule Meaning for interpretation
Item scale 0, 1, 2, or 3 points for each item Higher item scores indicate greater recent symptom intensity for that topic.
Item count 21 items All items are required before the total is final.
Reverse scoring None Every item adds points in the same direction.
Total range 0 to 63 The maximum is 21 items times 3 points.
Item 9 Included in the total and flagged separately when above 0 Safety review is not replaced by the total score.
Severity band Lower bound Upper bound Boundary rule
Minimal 0 13 Includes totals from 0 through 13.
Mild 14 19 Begins at 14 and ends at 19.
Moderate 20 28 Begins at 20 and ends at 28.
Severe 29 63 Begins at 29 and includes the maximum possible total.

The cutoff context is a distance note around those boundaries. In the minimal, mild, and moderate bands, it reports how many points remain before the next band starts. In the severe band, it reports whether the score is at the severe entry point or how many points above 29 it sits. This does not change the official band; it helps prevent a 19 and a 14 from being read as equally close to moderate.

Review group Items included Maximum points Use
Cognition and outlook 1, 2, 3, 4, 5, 6, 14 21 Organizes sadness, pessimism, past failure, pleasure, guilt, punishment feelings, and worthlessness.
Self-view and engagement 7, 8, 9, 10, 11, 12, 13, 17, 21 27 Organizes self-dislike, self-criticalness, suicidal thoughts or wishes, crying, agitation, interest, indecisiveness, irritability, and sex interest.
Energy and body rhythm 15, 16, 18, 19, 20 15 Organizes energy loss, sleep change, appetite change, concentration difficulty, and fatigue.

The three review groups are report aids, not official BDI-II subscales. The formal score remains the 0 to 63 total and its severity band. Driver items are sorted by item score, with item number breaking ties, so the highest-scored symptoms stay visible without changing the arithmetic.

Limitations and Privacy Notes:

BDI-II output is informational self-report screening support. Depression symptoms overlap with many other conditions and situations, and a proper diagnosis depends on a clinical interview, history, impairment, timing, risk, and differential causes.

  • Do not use the score as a diagnosis, treatment decision, or emergency safety assessment by itself.
  • Do not ignore Item 9 because the total is minimal or mild.
  • Do not compare the total with a different depression scale such as PHQ-9 or CES-D as if the scores were interchangeable.
  • Scoring runs in the browser, but copied text, exported files, and shared result links can contain sensitive answer information.
  • The BDI-II is a copyrighted professional instrument; an informational scoring summary is not a licensed replacement for official materials or qualified interpretation.

Worked Examples:

A lower total with a clear driver item

A person completes all 21 items and gets Total score: 12/63 with Overall lane: Minimal and Support urgency: Routine monitoring. If Highest-scored driver items shows Tiredness or fatigue at 3/3, the total is still minimal, but the follow-up conversation should not ignore fatigue, sleep, workload, medical issues, or medication changes.

A mild score one point below moderate

A Total score of 19/63 produces Overall lane: Mild. The Cutoff context says the score is 1 point below moderate, so the word mild should be read with care, especially if several items are at 2 or 3 and daily function is getting harder.

A safety item changes the response

A result may show Total score: 15/63 and Overall lane: Mild, but Item 9 1/3 changes the next step. The Support urgency output becomes Direct human follow-up, because suicidal thoughts or wishes should not be left as routine monitoring.

No report appears yet

If the progress bar shows 20/21 answered, the final report is incomplete. Use the question navigator to find the unanswered item, choose its 0 to 3 response, and then review the Total score, Item 9 badge, Score lane dial, and Answer review.

FAQ:

Can a BDI-II score diagnose depression?

No. The score is a self-report measure of symptom severity. Diagnosis requires clinical judgment, history, impairment, risk assessment, and possible medical or substance-related causes.

What should I do if Item 9 is above zero?

Treat it as a direct human follow-up signal, even when the total score is not severe. If safety feels uncertain now, use emergency services, a crisis line, or someone trusted who can stay with you.

Why does the report not appear after I started?

The report appears only after all 21 items have a 0 to 3 answer. Check the progress count and use the question navigator to find any item that is still unanswered.

Are the review groups official BDI-II subscales?

No. Cognition and outlook, self-view and engagement, and energy and body rhythm are local report aids. The formal BDI-II result is the 0 to 63 total and its severity band.

Are my answers sent away for scoring?

Scoring runs in the browser. Sharing a result link, copying answer rows, or exporting files can expose sensitive answers, so use those actions only when the recipient and storage location are appropriate.

Can I compare this total with PHQ-9 or CES-D scores?

No. Different depression scales use different items, scoring ranges, and cutoffs. Compare BDI-II totals only with other complete BDI-II results gathered under similar conditions.
