This radar keeps the four CES-D cluster totals on a normalized scale so it is easy to see whether the week leaned more toward mood, somatic strain, interpersonal strain, or reduced positive affect.
The cluster chart adds structure to the screening readout, but the total score and selected threshold profile remain the primary screen context.

CES-D-20 is a screening instrument, not a diagnosis. These threshold profiles change the comparison line only; they do not change the raw total.

Depressive symptoms are patterns in mood, energy, sleep, appetite, concentration, and social withdrawal that can build across an ordinary week. The CES-D-20 turns that recent pattern into a structured screening score, which helps you see whether the last seven days look closer to a passing rough stretch or to a symptom load that deserves follow-up.
This package asks all 20 CES-D items, scores them on the usual 0 to 3 scale, and returns a Total score from 0 to 60 alongside a Band, a selected screening threshold, and a Dominant cluster. That makes it useful when you want a repeatable snapshot before a therapy visit, after a difficult week, or at the start of a recheck plan.
The output still needs restraint. A high CES-D score does not by itself diagnose depressive disorder, and a lower score does not prove that symptoms are trivial, temporary, or unrelated to health, medication, grief, stress, or another condition. The tool measures recent self-reported symptom burden, not cause, prognosis, or treatment need.
Privacy needs the same kind of caution. Scoring stays in the browser, but the package also mirrors the encoded response string and settings into the page URL, so a copied link can expose answers even though the score is not sent to a bundled server endpoint.
A sensible first pass is to leave Threshold profile on Community screen (16+), answer the items for the last seven days as they were actually lived, and treat the first result as a baseline rather than a verdict. If you are using the tool to prepare for a clinical follow-up conversation, the stricter Clinical follow-up screen (20+) can be useful, but it changes the comparison line rather than the underlying score.
The most useful trust check is to read the snapshot in sequence. Start with Total score, then look at Threshold and Above threshold, and only after that use Dominant cluster to see what is carrying the week. A total that is being pushed by sleep, appetite, concentration, and effort can call for a different next conversation than the same total driven mostly by loneliness, sadness, and hopelessness.
A common misread is to switch from Community screen (16+) to High-specificity screen (24+), watch the Band change, and assume the symptom week improved. It did not. The tool only changed the threshold used for interpretation. Another misread is to treat Positive affect (reverse keyed) as a positive score. In this package, a higher value there means fewer positive endorsements during the week, not better mood.
If the result is concerning, open Symptom Clusters and confirm which items are actually contributing before you share or compare the score. Then keep the same Threshold profile and the same seven-day recall window on the next run so the trend means something.
The CES-D-20 is a symptom-frequency screener, not a diagnostic interview. Each item asks how often something was true in the last seven days, and the package converts each answer into a scored value from 0 to 3 before summing the full set into Total score.
Most items follow the obvious direction: more frequent symptoms add more points. Four positive-affect items are reverse keyed so that higher final values still mean more symptom burden. In this package those are items 4, 8, 12, and 16, which means strong positive endorsements reduce the score while missing or rare positive experiences raise it after reversal.
The result is then broken into four cluster totals. Depressed mood covers sadness, fear, loneliness, and failure-type thoughts. Somatic / activation captures appetite, concentration, sleep, effort, and getting-going problems. Interpersonal strain comes from the two relationship-friction items. Positive affect (reverse keyed) summarizes the reversed positive items. The Dominant cluster is whichever subtotal is largest.
Threshold profile changes interpretation, not measurement. The package compares the same Total score against 16, 20, or 24 points, then assigns a Band by fixed boundaries above that threshold. Guidance focus and Recheck window do not affect scoring at all. They only change the follow-up text and reminder interval that appear after the assessment is complete.
That distinction matters when you compare runs. If you want week-to-week tracking, keep the same threshold profile each time and keep the same seven-day recall frame. Otherwise, a changed Band may reflect a different interpretation rule rather than a real symptom shift. It also matters for privacy because the response pattern is encoded into the query string, so the package is local for scoring but not automatically private once the URL is shared.
The scoring model is a sum of item scores after reverse handling for the four positive-affect items. In the notation below, x_i is the raw answer, s_i is the scored answer, T is Total score, and theta is the selected Threshold.
Once each item is scored, the package adds all 20 values to produce the final total.
Banding is fixed: Below threshold when T < theta, Elevated symptoms when theta <= T < theta + 8, High symptom load when theta + 8 <= T < theta + 16, and Very high symptom load when T >= theta + 16.
A concrete example shows why threshold and score must be kept separate. If the 16 non-reverse items add to 18 raw points and the four reverse-keyed items are answered 2, 2, 1, and 0, those four become 1, 1, 2, and 3 after reversal. The final total is therefore T = 25. Under Community screen (16+) that lands in High symptom load. Under Clinical follow-up screen (20+) the same 25-point week becomes Elevated symptoms.
A consistent run is short, but the details matter if you plan to compare scores later.

A score below the threshold means the chosen screen boundary was not crossed. It does not mean symptoms are absent, mild in every domain, or irrelevant to current functioning.
If the score reaches or exceeds the threshold, the next check is whether the pattern is just over the line or much further above it. Above threshold and Band tell you that part. Dominant cluster tells you where to look next. A high total with Somatic / activation on top invites a different follow-up conversation than a high total dominated by Depressed mood or Interpersonal strain.
Do not overread the labels. Very high symptom load is not a diagnosis, and a lower band does not clear the situation if safety, function, or persistence are worsening. The best verification step is to cross-check the total against the item-level table and then rerun later with the same Threshold profile so the comparison stays fair.
A first self-check stays on Community screen (16+) and ends with Total score = 14, Threshold = 16, Band = Below threshold, and Dominant cluster = Somatic / activation. That does not cross the package's default screen line, but it still points to a week where sleep, appetite, concentration, or effort may be carrying more of the problem than mood items alone.
Another run uses Clinical follow-up screen (20+) and finishes with Total score = 20. The package reports Above threshold = 0 and Band = Elevated symptoms because the total lands exactly on the selected threshold. If the same answers were read under Community screen (16+), the total would still be 20, but Above threshold would become 4. The week did not change. Only the comparison frame did.
A common troubleshooting moment happens when a user answers 19 items and waits for a result that never appears. In this package there is no partial score card. The progress bar must reach 20/20 answered before CES-D-20 Snapshot, Interpretation, and Mood Signal Gauge render. If those sections are missing, check for the unfinished item before you assume the tool failed.
This assessment is informational and should not be used as a diagnosis or as a stand-alone treatment decision. If symptoms are intense, persistent, or tied to safety concerns, use the score as a prompt for qualified local support rather than as a reason to wait for another recheck window.
