Formula Used

This tool estimates recurrence using episode counts across the selected observation period. It converts the observed count into monthly, quarterly, and annualized frequency values for easier review.

Total Episodes = Depressive + Hypomanic + Manic + Mixed

Episodes Per Month = Total Episodes ÷ Observation Months

Annualized Episode Frequency = Episodes Per Month × 12

Total Symptom Days = Depressive Days + Hypomanic Days + Manic Days + Mixed Days

Average Days Per Episode = Total Symptom Days ÷ Total Episodes

Weighted Episode Burden Score = (Depressive × 2) + (Hypomanic × 1.5) + (Manic × 3) + (Mixed × 3.5) + (Hospitalizations × 4) + (Emergency Visits × 2) + (Missed Treatment Days × 0.1)

Annualized Burden Score = Weighted Burden Score ÷ Observation Months × 12

Quarterly Episode Estimate = Episodes Per Month × 3

The burden score is a tracking measure, not a diagnosis. It helps compare periods using the same input method over time.

How to Use This Calculator

Enter the number of months covered by your observation period. This can be a quarter, half year, full year, or another tracking window.

Fill in episode counts for depressive, hypomanic, manic, and mixed episodes. Then enter the total symptom days recorded for each mood state.

Add supporting care indicators, including hospitalizations, emergency visits, and missed treatment days. These values affect the burden score.

Press the calculate button. The result panel will appear above the form and below the header, showing frequency metrics, trend indicators, and a graph.

Use the export buttons to save a CSV file or a PDF summary. This can support case reviews, personal logs, or appointment preparation.

This tool is educational and organizational. It does not diagnose bipolar disorder or replace professional mental health assessment.

Frequently Asked Questions

1. What does this calculator measure?

It summarizes episode counts, symptom days, annualized frequency, and a weighted burden score. It helps track patterns over a chosen period.

2. Is this calculator a diagnostic tool?

No. It is a tracking and planning tool. Diagnosis and treatment decisions should come from a qualified mental health professional.

3. Why does the tool annualize episode frequency?

Annualizing helps compare different observation periods fairly. A six-month record and a twelve-month record become easier to interpret side by side.

4. What is the burden score used for?

It combines episode types and care events into one trend measure. It supports period-to-period review, not clinical diagnosis.

5. Can I use partial-year data?

Yes. Enter the exact number of months you tracked. The calculator scales the result to monthly, quarterly, and yearly estimates.

6. Why are mixed and manic episodes weighted more?

They are often tracked as higher-impact events in monitoring systems. The weights are practical scoring choices for comparison only.

7. What if I recorded symptom days but no episode count?

Enter the best documented episode counts available. The tool can still total symptom days, but frequency metrics need episode numbers.

8. Should I share exported results with a clinician?

Yes, if you want structured discussion support. Exported summaries can help organize timelines, recurrence, symptom days, and care events.
