Hello, fellow math enthusiasts and mood detectives! Get ready to crunch some numbers and decipher your feelings with the Major Depression Inventory (MDI) Calculator. Who said math was only for figuring out how many slices of pizza you can afford or how much tip to leave?

MDI Calculation Formula

To unravel the mystery of your mood, here’s the secret formula:

MDI Score = Sum of all item scores

Each item is scored from 0 (as absent as your ex) to 5 (as present as your shadow).

MDI Score Interpretation

MDI Score Interpretation
0-20 No or doubtful depression
21-25 Mild depression
26-30 Moderate depression
31+ Severe depression

MDI Calculation Examples

Example Calculation Interpretation
Alice scores 1 on all items (Alice is a bit of a minimalist) 1*12 = 12 No or doubtful depression
Bob scores 3 on all items (Bob is a bit generous with his scores) 3*12 = 36 Severe depression

MDI Calculation Methods

Method Advantages Disadvantages Accuracy Level
Self-Report Easy to administer May be biased (like your mom’s opinion about you) Moderate

Evolution of MDI Calculation

Year Change
1995 MDI introduced (like the new kid on the block)
2001 Validation of MDI for clinical use (MDI got its diploma)

Limitations of MDI Accuracy

  2. Bias – Individuals may under- or over-report symptoms, like a fisherman describing the size of his catch.

Alternatives to MDI Calculation
