This calculator estimates mixed symptom burden using paired manic and depressive symptom ratings. It highlights total severity, domain balance, and a combined index for structured self-reflection.
Calculator Inputs
Rate each symptom from 0 to 4. Use 0 for absent and 4 for very severe.
Example Data Table
| Symptom | Sample Score | Domain | Meaning |
|---|---|---|---|
| Elevated Mood | 2 | Manic | Mild but noticeable uplift. |
| Irritability | 3 | Manic | Frequent agitation and reactivity. |
| Racing Thoughts | 3 | Manic | Fast and crowded thinking. |
| Decreased Need for Sleep | 2 | Manic | Sleeping less than usual. |
| Depressed Mood | 3 | Depressive | Low mood most days. |
| Anhedonia | 2 | Depressive | Reduced pleasure and interest. |
| Fatigue | 2 | Depressive | Lower energy and stamina. |
| Concentration Issues | 3 | Depressive | Focus and decisions feel harder. |
Formula Used
Manic Domain Score = Sum of 6 manic symptom ratings.
Depressive Domain Score = Sum of 6 depressive symptom ratings.
Total Symptom Score = Manic Score + Depressive Score.
Normalized Index = (Total Score ÷ 48) × 100.
Balance Score = 100 − ((|Manic Score − Depressive Score| ÷ 24) × 100).
Mixed Intensity Index = (Normalized Index × 0.70) + (Balance Score × 0.30).
The balance component increases the index when both domains are active together. That helps the calculator reflect overlap, not just raw severity.

Frequently Asked Questions
1. What does this calculator measure?
It estimates mixed symptom burden by combining manic and depressive self-ratings. It also checks how balanced both domains are, because overlap matters in mixed presentations.
2. Is this a diagnostic tool?
No. It is an informational scoring tool only. It cannot diagnose bipolar disorder, depression, or any other mental health condition.
3. Why are there two domain scores?
Mixed features involve symptoms from more than one mood state. Separate domain totals show whether one side dominates or both are active together.
4. What is the balance score?
The balance score rewards symptom overlap. If manic and depressive totals are closer together, the balance score rises and the mixed intensity index becomes higher.
5. What score range is possible?
Each symptom ranges from 0 to 4. The full symptom total ranges from 0 to 48, while the mixed intensity index is reported as a percentage.
6. Can I use this for follow-up tracking?
Yes. Repeating the same ratings over time can help you compare patterns, discuss changes, and monitor whether overlap appears more or less prominent.
7. Does a high score mean severe illness?
Not by itself. A high score means greater reported symptom burden and overlap within this tool. Clinical context and professional assessment still matter.
8. Why include a chart and exports?
The chart makes domain differences easier to read quickly. CSV and PDF exports help with recordkeeping, trend reviews, and structured conversations.
