A Depression Screening Score Is Not a Diagnosis

A questionnaire can organize information about symptoms, but its total cannot establish a diagnosis on its own. What happens after the score is important.

The key distinction

Screening usually means checking a defined population before a condition is known or suspected. Assessment prompted by symptoms is a different situation. A clinician considers history, functioning, context, physical health, other conditions, and safety rather than treating a score as the entire story. Different guidelines also reach different conclusions about routine population screening. Those disagreements should not be reduced to a claim that people should avoid discussing concerns.

What the research adds

A 2025 CMAJ guideline recommends against routine questionnaire-based depression screening of all adults in its defined population, while emphasizing attentive clinical care. Its recommendation excludes people with current symptoms suggesting depression, a history of depression, or an existing diagnosis. A 2023 US recommendation reaches a different conclusion for population screening. Read the journal source.

Different guideline groups can weigh evidence and healthcare systems differently. Neither recommendation says to ignore symptoms or avoid seeking help. Screening, a clinical assessment prompted by concerns, and a diagnosis must not be treated as the same event.

A useful next step

If you have completed a questionnaire, bring the responses and any concerns about how questions fit your experience. Explain changes over time and what is becoming difficult. Do not use a low score to dismiss severe distress or a high score to select a treatment yourself. Ask what the tool is intended to do, whether follow-up is available, and how the clinician interprets it in context. This article intentionally omits scoring thresholds because a threshold without assessment can create false certainty.

Questions to consider

• Is this screening or an assessment of symptoms I already have?
• What follow-up does this result lead to?
• What important context does the questionnaire miss?
