Introduction:
The Beck Depression Inventory-II (BDI-II) measures how intensely you have experienced 21 depressive symptoms during the past two weeks. For each item you choose one of four statements that best matches your recent mood, energy, or outlook, generating a numeric reflection of emotional wellbeing. The instrument is brief yet clinically validated, making it suitable for personal screening or session preparation.
Scores for each statement range from 0 (not at all) to 3 (severe). Adding the 21 scores yields a total between 0 and 63. Thresholds partition that range into Minimal, Mild, Moderate, and Severe bands, offering an evidence-based snapshot of depression level that clinicians and researchers use to track change over time.
Complete the questionnaire privately in under three minutes to review the result with a counsellor or doctor later; do not change medication or therapy without professional advice.
This self-assessment does not provide a medical diagnosis.
Technical Details:
The calculation treats each response as an ordinal value and sums all 21 numbers to obtain a single depression-severity index, then classifies it into one of four evidence-based severity bands.
Although each symptom differs qualitatively, summing them produces a unidimensional score closely correlated with clinical ratings and treatment outcomes, supporting rapid screening and progress monitoring.

Calculations & Scoring:
The tool converts each chosen statement into a numeric value, sums all 21 values, then maps the total to a severity band.
Each chosen statement holds a preset score from 0 to 3.
Adding all 21 values produces your raw BDI-II score.
The total falls in the Moderate band, indicating clinically notable symptoms.
Final Result
Your BDI-II score and severity band appear above the interactive chart.

FAQ:
Quick answers to common questions:
What does my score mean?
A higher score reflects more severe depressive symptoms. The severity band under your total explains the range.
Is my data stored?
No. All calculations run locally in your browser and nothing is sent to any server.
How often should I retake it?
Weekly or fortnightly retesting helps track mood trends, but always discuss persistent concerns with a professional.
Can this replace professional evaluation?
No. The inventory aids self-reflection but cannot diagnose or plan treatment.
What if I score high?
Consider contacting a qualified mental-health provider promptly and share your results to guide the conversation.
