Depression, anxiety, and stress scores are concise summaries of how often symptoms showed up over the past week. They support reflection and timely care decisions.

You answer a set of everyday statements and choose how much each applied. The totals for three domains reveal where your scores sit from low to very high.

Results highlight the highest area, list stronger and quieter items, and suggest next steps you can try. You can review every answer before finishing so you know what drove the result.

A quick run might sound simple yet small measurement habits raise clarity. Answer in one sitting, keep the same time of day, and focus on the past seven days.

Estimates are informational and do not replace professional care. If safety is a concern speak to a qualified clinician.

Technical Details:

The assessment measures how frequently experiences related to low mood, anxious arousal, and tension occurred in the past week. Scores are organized into three domains labelled Depression, Anxiety, and Stress, each summarizing fourteen items on a four‑point scale from never to most of the time.

Each domain total is the sum of its item responses, with higher totals reflecting greater severity. These totals are interpreted using cut scores that place results into Normal, Mild, Moderate, Severe, or Extremely Severe bands. Values that sit near a boundary should be read with care, and retesting after a short interval can help confirm direction.

Comparisons are most reliable within the same person over time. People with identical totals may endorse different item patterns, so the strongest individual items can be useful for planning small changes.

D = ∑ i∈Dep ri A = ∑ i∈Anx ri S = ∑ i∈Str ri
Symbol Meaning Unit/Datatype Source
D Total for Depression domain integer (0–42) Derived
A Total for Anxiety domain integer (0–42) Derived
S Total for Stress domain integer (0–42) Derived
ri Response to item i integer (0–3) Input
Worked example. Suppose the fourteen item sums are D = 16, A = 10, and S = 22. Using the bands below, all three totals map to Moderate. The most elevated area is Stress at 22, so near‑term actions can focus there first.
Domain Band Lower Upper Implication
Depression Normal 0 9 Within typical range.
Mild 10 13 Monitor and support basics.
Moderate 14 20 Consider guided self‑help.
Severe 21 27 Seek structured support.
Extremely Severe 28 42 Prioritize professional care.
Anxiety Normal 0 7 Within typical range.
Mild 8 9 Monitor and support basics.
Moderate 10 14 Consider skills practice.
Severe 15 19 Seek structured support.
Extremely Severe 20 42 Prioritize professional care.
Stress Normal 0 14 Within typical range.
Mild 15 18 Monitor workload and rest.
Moderate 19 25 Add breaks and boundaries.
Severe 26 33 Seek structured support.
Extremely Severe 34 42 Prioritize professional care.

Units, precision, and rounding:

  • Item responses are integers from 0 to 3.
  • Domain totals are integers from 0 to 42.
  • Severity bands use inclusive bounds at each cut score.
  • Progress percentage rounds to the nearest whole number.

Validation and bounds extracted from the app:

Field Type Min Max Step/Pattern Error Handling
Item response number 0 3 step 1 Not applicable
Responses array array 42 42 length 42 Required to complete scoring
Encoded responses r string 42 42 [0-3\-]{42} Invalid strings are ignored

I/O formats and outputs:

Input Accepted Families Output Encoding/Precision Notes
42 item choices four‑point frequency scale Domain totals and severity bands integers and labels Chart appears after all items are answered
Answer exports copy or file CSV or DOCX summary text rows and table Exports list items and selected responses

Networking and storage behavior:

  • Scoring runs on the device; no server calls are made during scoring.
  • Answers can be encoded in the URL parameter r to resume later.
  • No server‑side storage of responses is used.

Performance and determinism:

  • Computation is linear in the 42 items and completes instantly on typical devices.
  • Identical inputs always yield identical totals and bands.

Assumptions and limitations:

  • Heads‑up Results reflect the past seven days only.
  • Heads‑up Band labels are coarse categories, not diagnoses.
  • High totals may arise from a few very strong items or many moderate items.
  • Incomplete responses prevent charting and document export.
  • Comparison across people can be misleading without context.
  • Cut scores are fixed in the app and do not adjust for population mix.
  • Self report may vary with time of day and recent events.
  • Sharing a link with encoded answers may reveal personal information.

Edge cases and error sources:

  • Accidentally skipping items lowers totals.
  • Choosing the same option for every item can hide meaningful differences.
  • Using a screen reader without focus cues may skip the next item.
  • Very fast answering can reduce reliability.
  • Manually editing the encoded string r can invalidate loading.
  • Clearing the page state loses unsaved progress.
  • Blocked clipboard permissions can stop the copy option.
  • File download prompts may be disabled by device policy.
  • Chart will not render until all items are answered.
  • Rounding near boundaries can make a score look tied across domains.

Step‑by‑Step Guide:

The assessment summarizes the past week into three domain scores and bands.

  1. Read each statement and select a choice for how much it applied.
  2. Move through all forty two items until the progress shows complete.
  3. Review the highlights and the most elevated domain.
  4. Check the strongest items and the suggested next steps.
  5. Optionally export your answers or copy them for records.
Example. If Stress totals highest, try small breaks, clearer boundaries, and fewer late notifications this week, then retake to compare.

Finish by choosing one small action based on your strongest items.

FAQ:

Is my data stored?

Scoring runs on the device and responses are not sent to a server. You can optionally keep answers via export or an encoded link.

Avoid sharing links that include sensitive responses.
How accurate is this?

Totals reflect your answers and band rules in the app. Repeating under similar conditions improves reliability, especially when near a boundary.

What formats are supported?

You can copy a comma separated table or download a document summary of questions and selected responses.

Can I use it offline?

Once the page has loaded, scoring continues without a connection. Exports and copying depend on device permissions.

How long does it take?

Most people finish in under three minutes. Taking a moment to reflect can improve consistency across items.

How to calculate DASS 42 scores?

Add item values within each domain to get three totals, then read the band from the cut score table for each domain.

What does a “borderline” result mean?

Values near a cut score can move bands on a retest. Recheck in a few days, keep inputs consistent, and focus on item patterns.

Are there costs or sign ups?

No accounts are required. You can use it without registering.

Troubleshooting:

  • No progress change → be sure a choice is selected for the current item.
  • Chart missing → answer all items to unlock the chart.
  • Copy fails → allow clipboard access or use the download option.
  • Download blocked → check device policy or choose a different folder.
  • Encoded link does not load → confirm it contains exactly 42 characters.
  • Scrolling the question list is difficult → use the main choices area to advance.

Advanced Tips:

  • Keep runs comparable by using the same part of the day.
  • If items feel unclear, jot a quick example to guide future runs.
  • Track one or two high items with a simple daily note.
  • Compare the range across domains to spot skew toward one area.
  • Revisit next steps after a week and adjust one variable at a time.
  • Use exports to discuss patterns with a trusted supporter.
