How StressCast works
Everything here can be reproduced with a calculator.
What it calculates
StressCast calculates a 0–100 work-related burnout score from the seven Work-related items of the Copenhagen Burnout Inventory (CBI). Each response maps to 0, 25, 50, 75 or 100 points and the seven values are averaged. The item about having enough energy for family and friends is reverse-scored.
The score describes your current self-reported experience. It is not a diagnosis and does not claim that you have a condition. The World Health Organization classifies burnout as an occupational phenomenon, not a medical condition.
The seven items
| Item | Scale | Direction |
|---|---|---|
| WB1To what degree is your work emotionally exhausting? | Degree | Direct |
| WB2To what degree do you feel burned out because of your work? | Degree | Direct |
| WB3To what degree does your work frustrate you? | Degree | Direct |
| WB4How often do you feel worn out at the end of the working day? | Frequency | Direct |
| WB5How often are you exhausted in the morning at the thought of another day at work? | Frequency | Direct |
| WB6How often do you feel that every working hour is tiring for you? | Frequency | Direct |
| WB7How often do you have enough energy for family and friends during leisure time? | Frequency | Reverse-scored |
What the 30-day scenarios mean
The scenarios are not a clinical prediction or a probability. They are a conditional what-if simulation: No change keeps your current score; Improve shows the arithmetic if up to two eligible items moved down one category; Worsen shows it if they moved up one category. One category change in one item moves the average by about 3.6 points (25/7).
The two-item rule is a product sensitivity assumption, not evidence that the change will happen in 30 days.
A worked example
Responses: high, somewhat, somewhat, always, often, sometimes and seldom (energy item, reverse-scored). Burden points: 75, 50, 50, 100, 75, 50 and 75. Mean = 475 / 7 = 67.9. Improve = 67.9 − 2 × 3.57 = 60.7; worsen = 67.9 + 2 × 3.57 = 75.0.
| Item | Response | Burden points |
|---|---|---|
| WB1Emotional exhaustion at work | To a high degree | 75 |
| WB2Feeling burned out because of work | Somewhat | 50 |
| WB3Work frustration | Somewhat | 50 |
| WB4Feeling worn out at the end of the day | Always / almost always | 100 |
| WB5Exhaustion in the morning at the thought of work | Often | 75 |
| WB6Every working hour feeling tiring | Sometimes | 50 |
| WB7Low energy for family and friends (reverse-scored) | Seldom | 75 |
| Current score | 67.9 | |
| Conditional improve | 60.7 | |
| Conditional worsen | 75.0 | |
Where the data comes from
The questionnaire and scoring come from Denmark’s National Research Centre for the Working Environment (NFA). The PUMA material reports, for Work-related Burnout, a mean of 33.0, a standard deviation of 17.7, N = 1,910 and a Cronbach alpha of 0.87; in that population of human-service professions, 19.8% scored 50 or above. Validation studies exist for Spanish and Brazilian Portuguese, but Danish values are not global norms.
How reliable is it?
The arithmetic is exact and deterministic. The CBI shows good internal consistency in the cited studies. StressCast v1 has not been validated to predict an individual’s score 30 days later, which is why scenarios are presented as what-if paths and never as probabilities.
Limits
The score depends on self-report and can vary with moment, context and how you read the questions. The PUMA comparison comes from a Danish sample of human-service professions and is not a global percentile. Do not use the result for employment decisions about another person.

What the 30-day curve means
The curve is not a clinical prediction or a probability. It is a conditional scenario simulation:
- “No change” keeps your current score.
- “Improve” shows the mathematical result if up to two eligible drivers move down one response category.
- “Worsen” shows the result if up to two eligible drivers move up one category.
One category change in one item moves the average by about 3.6 points (25/7). The “two items” rule is a product sensitivity assumption, not evidence that the change will happen in 30 days.
Data and confidence
The questionnaire and scoring come from Denmark’s National Research Centre for the Working Environment (NFA). NFA’s PUMA material reports contextual reference statistics for Work-related Burnout. Spanish and Brazilian Portuguese validation studies also exist, but Danish reference values are not global norms.
The arithmetic is deterministic and auditable. StressCast v1 has not been validated to predict an individual’s score 30 days later; that is why scenarios are presented as “what if” paths rather than probabilities.
Limits and notice
Results depend on self-report and may vary with context. Do not use StressCast to make employment decisions about another person. StressCast is a wellbeing and work-load reflection tool; it does not diagnose or treat medical or mental-health conditions and does not replace a qualified professional. If distress is severe, persistent, or affects safety or daily functioning, seek appropriate professional support in your country.
