FACIT Score Calculator
Use this tool to calculate a FACIT-style score with optional reverse scoring and prorating for skipped answers. Enter item responses from 0 to 4, where 0 is the lowest and 4 is the highest response value.
Tip: Check "Reverse-score" only for items that should be inverted. For reversed items, the calculator uses adjusted score = 4 - raw response.
What Is a FACIT Calculator?
A FACIT calculator helps you score patient-reported outcome questionnaires in the FACIT family (Functional Assessment of Chronic Illness Therapy). These tools are commonly used in research and care settings to measure quality of life, fatigue, and symptom burden over time.
The challenge with manual scoring is consistency. Some items may need reverse coding, and missing responses often require prorating. A calculator reduces arithmetic errors and gives you a quick summary you can track from one visit to the next.
How This FACIT Calculator Works
1) Set the number of items
Start by entering the total item count for your specific FACIT form or subscale. The calculator generates one input row per item.
2) Enter each item response
Type values from 0 to 4 in the response box for each answered question. Leave any skipped items blank.
3) Apply reverse scoring when needed
If an item is reverse-coded in your scoring guide, mark the reverse checkbox for that item. The tool automatically converts the score using:
Adjusted item score = 4 - raw item score
4) Prorating for missing responses
When some items are unanswered, FACIT methods often allow prorated scoring if enough items were completed. This tool applies:
Prorated total = (Sum of adjusted answered items × Total items) ÷ Number answered
What Results You Get
- Answered Items: How many responses were entered.
- Raw Sum: Total before reverse adjustments.
- Adjusted Sum: Total after reverse coding.
- Prorated Score: Estimated full-scale total when items are missing.
- Percent of Maximum: Prorated score expressed as a percentage of the scale maximum.
Important Interpretation Notes
Different FACIT instruments can have different interpretation rules. In some scales, higher is better; in others, domain context matters. Always interpret scores using the official scoring documentation for the exact instrument and language version you are using.
This calculator is designed for education and workflow support. It does not diagnose disease, replace clinician judgment, or substitute for validated software in regulated research workflows.
Best Practices for Accurate FACIT Scoring
- Use the exact questionnaire version and official scoring key.
- Confirm which items are reverse-coded before calculating.
- Set a minimum answered-item threshold and apply it consistently.
- Document whether scores are raw, adjusted, or prorated.
- Track changes over time rather than relying on one score alone.
