Screening vs Diagnosis

Understanding this difference is essential for using test results wisely. Online questionnaires are usually screening tools: they can highlight patterns and risk levels, but they do not provide clinical diagnoses.

What screening means

Screening is a quick method to estimate whether your answers are consistent with a pattern of symptoms or traits. It is designed to be practical and often prioritizes sensitivity (catching potential cases early).

What diagnosis means

Diagnosis is a clinical judgment made by a qualified professional. It requires more than a score: it integrates symptom patterns with context, duration, impairment, history, and alternative explanations.

Why online tests are usually screening

Online tests typically rely on self-report answers without a clinical interview. This makes them great for accessibility and quick insight, but it also limits certainty.

False positives and false negatives (in plain language)

Screening tools can sometimes flag risk when a diagnosis is not present (false positives) or miss a case (false negatives). This is normal and depends on cutoffs, the population, and how the test is used.

When to consider a professional evaluation

  • Symptoms are persistent (weeks or months) and feel hard to manage
  • Daily functioning is affected (work, relationships, sleep, routines)
  • You have safety concerns, panic episodes, or thoughts of self-harm
  • You want a clear differential picture and a personalized plan

FAQ

Can an online test diagnose me?

Most online tests are screening tools and cannot provide a diagnosis. Diagnosis requires a broader clinical assessment that considers context, duration, impairment, history, and alternative explanations.

Why do screening tools sometimes give false positives?

Screening aims to catch possible cases early. Stress, temporary life events, response style, and overlapping symptoms can raise scores even when a diagnosis is not present.

What does a professional assessment add?

Professionals integrate interview, history, context, differential considerations, and sometimes multiple instruments to reach a diagnosis and a personalized plan.
